back to article Note to Captain Kirk: Warp speed will kill you

A US boffin has effectively put the mockers on Star Trek-style warp speed travel to the stars by warning that interstellar hydrogen gas would become deadly to humans as they approached the speed of light. Professor William Edelstein of the Johns Hopkins University School of Medicine explained to New Scientist that while …

    Also I thought the warp engines (nacelles) create a kind of warp bubble around the ship allowing it to go at warp speed so surely the hydrogen would not affect the ship or crew?

    Besides, the whole point of warp drive is the ship is not travelling at FTL in the traditional sense.

    It's warping space around it so the space itself, the "warp bubble" enclosing the ship travels FTL while the space within the bubble the ship's going at sublight.

      Yeah. If you have already pulled off the seemingly impossible feat of FTL (ie;overcome what currently appears to be a sacrosanct limitation of the universe) then you can surely invent some other widget that overcomes the relatively banal issue of high-speed collisions.

      Personally I'd favour using a hyperdrive to jump out of realspace for the bulk of the journey that way I'm travelling in my own universe and I can make up all the rules.

      The biggest problem with any form of FTL travel is causality. It's a real bugger when you arrive back at your home with the groceries before you've actually arrived at the shop. Tesco get real arsey about that kind of thing..

    science and common sense

    Any normal person would know that in the startrek universe, they use Bussard ramjets for sub lightspeed travel. One caracteristic part of this system is the Bussard hydrogen collector on the front of each ship, that is used to capture interstellar hydrogen to be used as fuel in the ship's reactor. Actually, the writers of the original startrek seems to be better in science than the us professor. (remark: a Bussard ramjet consists of a hydrogen collector on the front, a fusion reactor in the middle and a plasma accelerator /vasimir/ in the back with plasma and electrical conduits between these parts and it is named after its inventor Robert W. Bussard)

    Warp bubble

    Wouldn't the hydrogen atoms (and anything else in the ship's path) be pushed aside by the warp field? The ship sits in a bubble of normal space surrounded by the warp field, which distorts spacetime outside the bubble, thus creating motion.

    Such matter could actually be useful as fodder for a more conventional MHD drive.

    Stupid

    This is stupid, because clearly ships powered by warp drives aren't operating in normal space; otherwise the Enterprise wouldn't be able to exceed the speed of light as handily as it does, as well as being able to avoid time dilation and other effects of near-lightspeed travel. If you are going to buy into the concept of warp drive to begin with, you'd have to acknowledge that it's not actually travel in any conventional sense, so pesky things like hydrogen atoms are irrelevant. Rather poor attempt at a thought experiment here, I'm afraid....

    Well gravity and acceleration never seemed

    Other solutions

    Magnetic shielding is the most likely way to go, along with ice (thick cometary fragments as shields, for example). However, assuming we do ever bother going deeper into space, it will be at speeds far below light speed for a long time to come, so I'm sure technology will figure out an answer to this as and when the technology to achieve it progresses. It's meaningless to compare a hypothetical future development with a modern-day prevention system. That's like somebody in the 1400s predicting computers, but complaining that there would be nothing to power them with.

    Faulty ASSumptions

    The assumption here is that the warp drive works the same way as conventional propulsion system - push from the back, with the front displacing any matter that gets in the way (air, water, etc)

    I propose that the warp drive works (at least partly) by displacing the matter in front of the craft, thus creating (even more of) a vacuum and pulling the craft forwards... a _bit_ like a jet engine if you will, but applied to the whole craft and over distances in the order of light-seconds.

    Warp speed

    I'd like to resalt the fact that warp speed, as seen in Star Trek films, exceeds c, so there have to be different physics involved, thank you.

    Primary, the branch that studies fictional physics.

    Of course, that don't invalidates the professor's study, that is applicable to our very real world, and if I one day happen to be flying in a spaceship fast enough to nottice its effects, i'll fondly remeber him.

    On the other way, there are far more bigger problems to get to such speed, as the acceleration needed would be far greater than the one my body would resist, for example, or the amount of energy involved to accelerate the ship.

Nacelles are usually separated from the main structure of the ship because of radiation generated by the nacelles; when at optimal levels, the radiation could be deleterious to the safety of ship and crew. (citation needed • edit)Nacelles are separated from the ship by large pylons, and usually house a Bussard ramscoop at the fore end, primarily used for collecting hydrogen from space. "

    But...

    Not that I'm trying to say Star Trek was real or resolved this issue in any way, but didn't the star ship have navigational deflectors to create a field around the ship which kept things like hydrogen away from the ship itself whilst it was traveling through space? Effectively putting it in some kind of 'happy bubble' for travel. It was a big enough thing in the show that when the navigational deflector was down they couldn't travel.

    "The navigational deflector (also called the deflector dish, the deflector array or the nav deflector) is a component of many starships, and is used to deflect space debris, asteroids, microscopic particles and other objects that might collide with the ship. At warp speed the deflector is virtually indispensable for most starships as even the most minute particle can cause serious damage to a ship when it is traveling at superluminal velocities."

    Potentially Star Trek still covers it's behind, as hydrogren still falls into the category of "....even the most minute particle...."

    Geek

    Star Trek Warp Speed is equal to or greater than the speed of light - involves a bubble of real-space, rather than flying through normal space-time - and all Federation ships have a navigational defelector specifically to protect the ship from particle strikes notwithstanding energy shielding designed to protect the ship from phasers, disruptors and other high energy weapons.

    Impulse (sub-light) propulsion is limited to a fraction of light speed to avoid the worst of time-dilation effects, further reducing the validity of this allusion.

    Bussard ramjet [Geek Alert]

    But with out the hydrogen the Enterprise wouldn't fly.

    From what I remember reading, the glowing front of the warp nacelles are Bussard Hydrogen Scoops. see [Bussard ramjet]

    These use huge magnetic fields to "scoop" up the hydrogen in front of the ship which is then used as fuel.

    This was the reason they on stalks away from the hull since the magnetic fields would rip the iron from your blood stream.

    It is also worth noting that hydrogen would only be a problem at impulse, since at warp speed, you are warping space around the ship and the ship is relatively stationary with in the warp bubble.

    Yes I know this is all pseudo-science, but you need to include the pseudo-facts.

    1. Kevin 6

      RE:Bussard ramjet [Geek Alert]

      Yup hence the term warp speed the ships not moving which is why its not outside the laws of physics. If you went at the speed of light from point A to get to Point C you would have to go through point B, but with warping the space you pretty much bend space and pull point C closer to you and go that way.

      And don't see how impulse power would be an issue either seeing there not going near the speed of light. Only time I can remember a ship actually going near the speed of light was StarTrek IV The Voyage home when they did a sling shot around the sun in a Klingon vessel, that almost ripped itself apart, to go through time.

    Wrong, wrong, wrong.

    In Star Trek the warp engines do not make the ship travel really, really fast (i.e. past light speed which according to Einstein is impossible anyway). The warp engines warp space around the ship and let you take a short-cut across space-time.

    Now impulse engines, which do move the ship really, really fast (close to the speed of light) they would cause the ship to have problems with colliding with hydrogen in space. Well except that in Star Trek every warp-capable ship has navigation shields for pushing aside space debris, which would cover the odd bit of hydrogen.

    In short: Star Trek is 40 years ahead of today's scientists: already thought of the problem and came up with a solution.

    If that's the biggest hurdle (which I'm pretty sure it isn't, I'd have thought the laws of physics would have been more of an obstacle) then it's hardly insurmountable. It's not like you can merrily bob about in space as it is - there's a huge amount of radiation already.

    So presumably all it needs is a way to shield against radiation and this no longer becomes a problem? Then you just have the laws of physics to contend with.

    I dunno about star trek specifically, but I recall several sci-fi settings where it's explicitly stated that ships simply use their normal battle defenses (deflector shields, force fields, whatever) while flying at relativistic speed. Once you accept the existance of an energy shield that can absorb hits from the sort of weaponry you see in average sci-fi, mere interstellar hydrogen can't possibly be a problem.

      And I'm sure I'm missing some obvious stuff.

      Honestly if it wasn't for the insanely vague patents big companies hold we'd probably already have most the stuff made that was in the shows that a sci-fi author dreamed up.

    :::trekkie alert:::

    erm yeah they thought of that already i know this shows i watched to much star trek but the large "deflector" dish on the front of the was there to push stray atoms out of the way so they didn't smash into the ship not just a gaint design feature (see gene did think about it)

    also since wrap drive is about compressing space and travelling across the compressed space so the enterprise relative to it self only ever traveled at 1/4 of the speed of light just to rest of the universe it seemed faster. Wrap is a factor of compression not a speed it just happens that the compression means they get they faster so the to get confused.

    the biggest problem is the amount of power needed to compression space was something like all the power the earth produces in a year for a few seconds at "warp one".

    they released a book called the science of star trek where they detailed all the issues and supporting theories for various technologies and i was good at physics at school and like startrek so i get it quite interesting (if your into physics) havn't read it in about 5 years so that's why the figures are abit vague.

    Warp -- emphasis on the warp -- drive

    Here I was thinking that a warp drive worked by warping space around you so you can cross from point A to point B, bypassing all the Space, and everything in it, between those two points.

    I'm no physicist, so I don't know why you might run into hopping across warped space using a fictional warp drive, but I hope this wasn't Edelstein's PhD dissertation.

    Hydrogen atoms move with the ship

    Warp drive is supposed to work by messing with the space along the path between the starting point and the destination. In the moving region near the Enterprise, space is normal. Around this normal region is a moving region that has a short distance from the start point to the destination. To compensate for this, space has a large distance between the start point and the destination when the ship is not nearby.

    Star trek's warp field is generated by the ship. As distortions in space travel at the speed of light, the Enterprise would not be able to distort the space ahead as required without magic. The solution is to send the required gravitational waves from the start point years before the journey starts so they will reach the destination when they are needed. (To get the right shaped space, the destination has to send gravity waves back to the source as well. The journey cannot start until those waves arrive.)

    The distortions in space that make the Enterprise's path short also affect the hydrogen along the path. Near the Enterprise you find the hydrogen that started near the Enterprise and travelled with the ship. Around that, hydrogen gets moved out of the way while the ship is nearby. Everywhere else, there is more hydrogen in the way.

    In real life, stars and black holes in tight orbits light years away do not create gravity waves big enough to be detected here by the most sensitive equipment currently available. Equipment big enough to make waves that could get the Enterprise to the nearest star in a few days would weigh more than the entire solar system. On the other hand, using slower than light ships and crews in suspended animation would remove all the urgency and excitement from a television series.

    Ok so hydrogen kills, give him a nobel prize

    the theory of warp speed is that space is compressed to allow the ship to move.

    hence why in voyager when tom paris breaks the warp 10 barrier he ends up being in all places at one time, because he has colapssed space into his warp field.

    the deflector moves things out the way, there bassard (SP) collectors collect up things that they want to reuse, the necelles generate the field hence them being symetricle allowing for a equal two bubbles to merge into one big field of protection.

    Star treks theory was all based on possible achiements.

    Are we going to have the same problem with 'news' that we have with patents? "I've not heard of anything, so I must be the first to (insert idea/patent)..."

    Wiki:

    The Bussard ramjet is a theoretical method of spacecraft propulsion proposed in 1960 by the physicist Robert W. Bussard.

    Bussard proposed a ramjet variant of a fusion rocket capable of fast interstellar spaceflight, using enormous electro-magnetic fields (ranging from kilometers to many thousands of kilometers in diameter) as a ram scoop to collect and compress hydrogen from the interstellar medium. High speed forces the reactive mass into a progressively constricted magnetic field, compressing it until thermonuclear fusion occurs. The magnetic field then directs the energy as rocket exhaust opposite to the intended direction of travel, thereby accelerating the vessel.

    Wiki:

    Project Daedalus was a study conducted between 1973 and 1978 by the British Interplanetary Society to design a plausible interstellar unmanned spacecraft... The ship would be protected from the interstellar medium during transit by an erosion shield. This would be made from beryllium due to its lightness and high latent heat of vaporisation. Larger obstacles that might be encountered while passing through the target system would be dispersed by an artificially generated cloud of particles, ejected by support vehicles.

    Oh dear

    Years ago, someone proved mathematically that one way to do Star Trek FTL would be to wrap a bubble of space-time around a ship and moving that bubble through normal space (at any speed you want - c limits are irrelevant because the two space-time strata are effectively separate universes).

    The hydrogen inside the bubble is not moving at any significant speed relative to you, so you don't have a problem with it. The hydrogen outside the bubble is in a different universe and has no way in to yours.

    As for how you fold space-time like that and propel it relative to the rest of space-time outside it, that's a different matter...

      @ Michael H.F. Wilkinson RE: After all, they allow cross-breeding

      There was an ST episode where they discovered that the humanoid races (Humans, Klingons, Vulcans,...) had a common ancestor - so the DNA would be nearly the same, with much less than a hundred thousand years of genetic drift.

      As for appearances being so different within such a relatively small time - note that dogs have amazing variability in appearance despite being virtually identical in DNA (hence being able to cross-breed).

      They never followed up that episode unfortunately....

      I once read a short story where the preponderance of humanoid races in this section of the galaxy (in the story!) is because a very intelligent race visited all the planets nearby and left behind their equivalent of cockroaches - which became humans.

    Mass Increase

    Since as speed approaches c, relative m increases, I would think that this problem should take care of itself. A normal hull should have significantly more mass under this formula than the atoms it would encounter. Time slowing in the frame of reference is indicative of this. A hull atom or molecule would be much harder to move, and thus more resistant to a particle that is relatively slower.

    Warp drive

    The ship never actually travels at relativistic speeds. While space is being warped, the ship uses its standard, newtonian-physics based impulse engines to move. This is why phasers can be fired at warp - because the ship isn't actually travelling faster than light, it just reaches its destination in a period of time that suggests it were.

    Bussard Ramjets!

    I'm being a trekker cynic here, but I don't believe that ST-TOS (The Original Series) EVER mentioned Bussard Ramjets in the series. This is real science grafted on to the story by fans who were keen to try to fill out the specifications of ships with something approaching real science (Bussard Ramjets being theoretical at the moment).

    I actually doubt that this type of propulsion fits, anyway. Hydrogen ramjets are only suitable for sub-light propulsion, and I'm sure that in Ringworld Engineers or Protector or one of Larry Niven's other novels (only a tenuous Trek link, but one of his stories was adapted for the ST-TAS (The Animated Series)), the sciency bit at the end says that hydrogen ramjets will only take you to half the speed of light, assuming that you can eject the hydrogen nuclei at close to the speed of light.

    If you look at pretty any of the Enterprise schematics, (NX-01 through 1701-E), I'm fairly certain that the impulse engines (sub-light propulsion) are on the back of the saucer, not in the nacelles. The nacelles are for generating the warp field, which has no current scientific grounding, and nothing to do with Bussard Ramjets.

    But there is a strong consensus that the dish at the front of the engineering hull (or on the front of the saucer on the NX-01) is to do with shields that are used when traveling at speed to deflect dust (and presumably hydrogen atoms).

    The problem of dust at speed has always been recognized in SCI-FI. EE 'Doc' Smith (one of the original Masters of Space Opera) used to equip his ships with armor several metres (I'm sure he used metres, strange really as he was an American) thick, and he made them tear-drop shape to reduce the drag.

      Yep, correct. All explained in great detail in the Star Trek Technical Manual. Enterprise-D actually had two sets of impulse engines, one on the saucer section and one on the primary hull, otherwise separating the saucer section would not be much use to anyone.

      The blobs on the front of the nacelles are actually called Bussard _Collectors_, and while they are indeed for collecting hydrogen, it's purely to supplement the onboard fuel supply.

      And yes, I know it's made-up pseudoscience, but it's interesting anyway :p As an aside, The Physics of Star Trek makes an interesting read if you're curious how plausible some of the technology in Trek actually is.

According to them (and no, I've not checked their calculations), it's completely theoretically possible to create a warp bubble around a starship.

    Occasionally they allow some through to supplement their fuel.

    See page 70 of the technical manual, and you'll know about the "Bussard Ramscoop Fuel replenishment system" that scoops up atoms of Hydrogen in front of them.

    Each nacelle has a Bussard collector in front.

    At sublight speed the coils sweep forward and collect particles.

    At warp speed the coils slow down the incoming matter so they can be collected if wished.

    But more usually the shields deflect the majority.

    See also page 48 where it talks in detail about the deflection of low-mass particles.

    See page 87+88 for detail about the deflector dish and a diagram for the shields deflecting the submicron particles.

    The main forward deflector dish deflects most of the matter at high speeds but a little is allowed to filter through to allow collection and so does not swamp the Bussard collectors.

    Bussard Ramscoops but no Bussard Ramjets

    The "Star Trek The Next Generation" guys, when doing the series' bible and the "science" behind the show, certainly did a good job at spotting the most obvious issues and formulating adequate treknobabble. That ST:TNG Technical Manual is a delight for science fiction aficionados.

    One problem with any scientist or science journalist that tries to har har at the series is that the people doing it had some scientific knowledge or knew who to consult. Of course, Trek's science is pants, mostly, but they acknowledge its problems even if just by plugging the holes with some dandy buzzword.

    So, anyway, there we go: the show's version of Warp Drive implies that the "subspace" bubble that propulsively distorts spacetime and also lowers the apparent mass of the ship to avoid a relativistic snafu is permeable to external particles in the way. So the navigational deflector pushes them out of the way or, if too big, the ship alters course and avoids them. That has been so since the original series.

    About the Bussard Ramscoops: they are there to collect interestellar hydrogen but they are not Bussard Ramjet engines at all. The idea is to collect matter and feed part of it into a matter-to-antimatter converter. Its efficiency is terrible, but as a M/AM reaction is the only means to feed the warp engines, the ramscoops are the only way to collect fuel if you run out of antihydrogen and have not enough hidrogen left to convert (one can imagine lots of nitpicks here, but…).

    I think they have never been used as intended in the show, really, but they have been featured here and there as some means to escape some tricky situations.

    I love technology-fiction, and I collect spacedrives as others do coins or stamps. I also happen to not have a life, sad anorak that I am.

    Misunderstaning

    First, Star Trek very clearly states that the ships main deflector is used to deflect matter away from the ship as it moves forward keeping the warp field clear. This would I assume include Hydrogen atoms just as it did micro meteors in "year of hell" in Star Trek Voyager.

    Second, ships in Star Trek don't travel at the speed of light. Instead they warp the space around them so there is less distance to travel at standard speeds, the higher the warp factor the greater the effect. It's like travelling straight between the top two points of a "U" instead of all around the "U" following the shape of the letter. Time would stop is you travelled at the speed of light so what fun would that be.

    Just to clarify about the bussard collectors, they are only designed as a fall back option in case the primary supply of deuterium is exhausted somehow -- enabling said vessel to "limp" back home where presumably it could be refueled. It would not be a viable long-term solution from what I understand of the fictional universe.

      Bussard collectors are on the nacelles, used to collect said hydrogen for the matter-antimatter reaction. Why carry both when matter is so plentiful, even in interstellar space. The deflector dish is a separate array for clearing space in front of the ship. Of course, neither of these are used at warp speeds since space itself is moving with the ship inside the warp bubble(s).

    Factual errors

    I think as a professor in Medicine he has no knowledge of the Faraday shield effect, but lets not kill a good story with facts...

  126. Charles 9 Silver badge

    I'm not the swiftest on the innards of Star Trek Warp tech...

    ...but the way I understand it, it works around the limitations of physics by creating a field around the ship that distorts (warps) its relation to the universe allowing it superluminal travel. I would imagine such fields could also function to deflect or displace the ambient hydrogen outside the warp field, preventing it from affecting the ship and all within. It's up to the trekkies now to write up some possible explanations.

      Re : Factual errors in your Factual errors?

      I'm not really sure that the Faraday Shield Effect would have any bearing on this problem. If we are talking about neutral atomic hydrogen, then there is no effect at all.

      If it is charged, that is one hell of a current you are "flying into" at one hell of a speed. I'm not convinced that the Faraday Shield Effect works as you anticipate when you are travelling to within a millionth of the speed of the magnetic field mediator itself.

      My money is on the guy with the PhD from Harvard, and a distinguished career in gravitational wave physics and the study and application of magnetism and magnetic resonance. I think it is safe to assume he knows a bit about the Farady Cage effect.

        talking out of my hat here, but ...

        Obviously, for a shield of this sort to work, the gaps in the mesh have to have a similar spacing to the wavelength of the incoming radiation. But since we're talking about hydrogen atoms which are accelerated to nearly c, we'll have a hard time creating a crystal lattice that's hard enough and dense enough to stop the radiation. Not to mention the size...

        But in one way, Faraday Cages aren't too far from the basic physics principles at play. The solution appears to be to use metamaterials, which are crystals or layered materials with the interesting property that they have a negative refractive index. When placed in front of the ship, incoming particles should be scattered in a cone away from the craft due to Cerenkov Radiation.

        I could have just copied and pasted some bits from the wiki page on Cerenkov radiation, but I figured talking about photonic crystals would probably have sounded like pure sci-fi.

      only at superluminal sppeds

      The Warp fields only apply for FTL travel, not at the impulse speeds mentioned (99.9999998% light speed). They carry the space around the ship through the Universe, compressing or 'warping' space in front and elongating space behind the ship since nothing in real space-time can exceed light speed.

    One more reason FTL travel is not currently possible possible.

    So, we have one more reason FTL travel might not be possible.

    This is to add to all the various dangers that they have already said will prevent it, be they radiation, gravity of local objects or anything.

    Well, 200 years ago, they thought it would be impossible for man to travel faster than 20 miles per hour because to go any faster would crush the skeleton. Guess what.. That theory turned out to be wrong. Even though there is a point at which acceleration causes the human body to cease working, that point occurs when you are travelling a lot faster than 20 mph. Even then, to some extents, technology allows use to mitigte the effects.

    My point is that for many reasons (this included), FTL travel is currently impossible. However, it may be that 200 years down the line, technology has progressed to the point where it can overcome the problems.

    1. Anonymous Coward
      Anonymous Coward

      Which is it?

      You're mixing acceleration with speed - the human body can survive travelling at any constant speed (within reason, as this article discusses). But I suspect it would disintegrate by accelerating up to as little as 5mph, if the time taken was short enough, and thus the acceleration to that speed great enough...

      If you accelerated from zero to 5mph in a thousandth of a second, that is a rather speedy and likely deadly acceleration of 2279g. It would rip you apart.

      "Even though there is a point at which acceleration causes the human body to cease working, that point occurs when you are travelling a lot faster than 20 mph."

      This so much fun but what has speed/velocity to do with acceleration. ?

      Acceleration between 0 and 5 mph would kill you if it were sufficiently rapid. Don't take my word for it just drop a fine wine glass onto concrete from ~20 cm

        I disagree with your example. "Acceleration between 0 and 5 mph would kill you if it were sufficiently rapid. Don't take my word for it just drop a fine wine glass onto concrete from ~20 cm" You cite a example of deceleration to prove your point of acceleration. I think a more appropriate example would be. Throw a very full water balloon too quickly and it will exploded in your hand from the gravities created by inertia. However there as been some work done, I beleive in Russia creating a dampening field. So far it requires 16 Tesla's to generate the power to lift a single frog and some modifications to the frog. It's still progress though.

          Relativity

          This is where that whole theory of relativity comes into play. Acceleration is just a change in velocity and direction over time. In the glass's frame of reference it is standing still and the ground is, in relative terms, moving towards it at high speed, thus when the ground impacts with the glass it is suddenly accelerated in a different direction relative to its own frame of reference.

    Warp does work

    Ok!.... so the original Phoenix was supposedly constructed of titanium, which in theory probably would not be able to withstand the Ionized radiation, but Zephram Cochrane survived so this must mean that the cockpit was lined with something else that was able to withstand the warp speed trial. lol

    But more modern ships such as the NX Enterprise had Polarized Duranium Hull Plating which protected the ship from phased energy beams, which also travel at the speed of light. Not only that but the NX Enterprise is equipped with a navigational deflector which if I am not mistaken is explained to be a shield that is operational during warp speed to deflect stray particles.

    So I guess that proves MR US Boffin Incorrect.

    Maybe his equations were based on strapping a pair of warp engines to as Cadillac. hahhahahahhahahhaha

    How can you call ANYONE a "boffin" when they clearly haven't watched/read enough Star Trek to know how this isn't a problem?!?

    Warp bubble - protects the ship while it travels at sub-light speeds therefore mitigating the collision speeds.

    Navigational deflector dish - what part of the word "deflector" befuddles you?

    BTW, for all those talking about the Bussard Ramscoops - may I point out that they are at the end of the warp nacelles, therefore BEHIND the leading edge of the dish? Not relevant.

    Note about relativity;

    When in a warp bubble, the ship travels at significantly BELOW light speed. There was a novel written (I think a TNG story) where some-one had lost everyone they knew apart from those on the ship because their warp drive failed and they spent a couple of years travelling at high impulse speed. Because they had then been travelling closer to light speed, time dilation was more noticeable and they had aged at a reduced rate relativr to everyone else in the universe.

      @Tony

      Check what a Bussard Ramscoop is. It projects a large magnetic field *ahead* of the ship to guide the hydrogen where it needs to go. Looking at the design of the ships, it would have to be a highly shaped field to avoid subjecting the saucer section to a possibly damaging strong magnetic field. And if the same basic design was used in the Intrepid class of ships (like NCC74656 Voyager), then it would have to be even more sophisticated, as the nacelles move (supposedly to make them more in line with the center of gravity of the ship).

      As I said before, I don't believe that the design of the NCC1701 Enterprise in the original series was actually scrutinized by engineers or scientists. The function of various parts of the ship was assigned by fans, some of whom ended up writing books. I would be interested to see how many of these works are actually regarded as canon, and have made it into the production bible for the various series.

    How to create a warp field

    spin a disk so tha it's axis is perpendicular to the surface of the earth and the outside edge exceeds orbital velocity. It will begin to negate the Earth's gravity field. The closet thing to a Warp engine on Earth at present is the LHC. Fashion a LHC which is coil shaped rather than cirular and you will have the beginnings of a subspace warp engine. (Didn't say this would be easy)

    PS The laws of Space Time Physics only apply to Matter, not empty space. It is the same time everywhere in the Universe. The "Clock Speed" of matter slows down as you approach the speed of light. In other words the speed of the electrons and protons slow down. Time doesn't speed up here on Earth if you blast thru space at Warp speed. Your atoms slow to a stop. To you the trip is nearly instantaneous. The trick will be STOPPING. Subspace is that space that exists beyond the speed of light. And yes Virgina, a deflector shield would be advisable.

    Warp Speed etc

    Hydrogen would not have any effect on a warp-capable ship due to the following:

    1. The warp nacelles create a bubble of sub-space through which the ship travels. The ship does not actually reach FTL but can travel such great distances due to the nature of sub-space. So, during warp travel the ship is not in normal space, but can 'see' normal space (hence the streaky stars and the ability to use sensors etc).

    2. The crew would not be mashed against the rear bulkhead nor the ship torn apart during acceleration due the the Inertial Dampening Field which surrounds the ship and the Structural Integrity Field.

    3. During normal impulse speeds the navigational deflector (the dish below the saucer section) would deflect any particles or debris that would damage or destroy the ship at these speeds. The main shields are not normally active unless needed to enhance the navigational deflectors or in a battle situation.

    Ignoring that part of physics that has always bothered me (go away, pesky mass increase) it would take about a year at 1 gravity acceleration to hit close to light speed.

    A couple of things

    Warp drive doesn't isolate the ship from surrounding space (it isn't really an Alcubierre-type drive but a "grab a wet soap bar and press until it shoots out your grip" drive, with extra apparent mass reduction effects), so the deflector beam must be active while at warp, as the warp bubble is permeable to external matter.

    Shields are gravity-based instead of magnetic.
