back to article Rock star physicist Cox: Neutrinos won't help us cheat time

Fire up the DeLorean and grab the almanac, time travel is here... or maybe not. Atom-smashers at CERN's subterranean Alpine lab seized the headlines recently when they found a set of subatomic particles once obscure outside the world of boffinry had turned scientific convention on its head by travelling faster than light. …

    There are other, simpler, discoveries in physics that have been made by studying what's on Twitter?

      . <-- The point You -->

      The point is that many people have been suggesting overly simplistic potential solutions on Twitter, Cox is saying that these have already been thought of. He's not saying that you can make scientific discoveries by looking at Twitter.

    2. Thomas 4

      Very well

      By analysing Twitter, we can deduce that stupidity travels faster than the speed of sound, using a set of particles known as morons.

      Cox is referring to Inevitable Internet Omniscience Syndrome, something that pops up everywhere that a bunch of people with a bare minimum of knowledge congregate and discuss things they don't really understand, combined with a fair bit of bashing academics and specialists who despite having worked on the problem for many, many years lack the piercing insight of a forum troll who can see the simple solution in moments.

      Cox is a fair bit more polite about the issue that I could be, or indeed the guilty parties deserve.

        No place for new thought?

        Agree that bashing the professional academics (especially on personal level) is uncalled for, but you seem to imply that anyone who is not already a professional scientist can't have a good idea? I seem to recall part of Einsteins success was that he didn't buy into the current accepted rules, and proposed what he thought made better sense, same with many other great thinkers and revolutionaries who challenged established thought?

        Sometimes, like maybe when all of science seems to agree that nothing can move faster than light speed, it takes a so called "person of minimum" knowledge to not know or accept this and actually maybe prove it wrong?

        And yes even the smartest minds sometimes miss the obvious, and sometimes the simplest minds discover it.....

          Einstein wrote papers which were accepted into journals and peer reviewed, his ideas were new, but they were backed up with hard science and the review from others. It was certainly not all people who liked him, especially at first, but suggesting that this equates to a bunch of people commenting on the Internet with no other knowledge of the subject, other than their personal theory, just doesn't stack up.

    This whole speedy neutrino business has no scientific merit whatsoever

    I think if we're going to crack this whole time travel thing we need to do what Superman did at the end of Superman The Movie and fly really really fast around the Earth until its rotation changes.

    It worked for Superman; Lois Lane died and then he brought her back to life.

      Superman did not change the rotation of the earth at the end of Superman: The Movie. That wouldn't reverse time on the planet below.

      No, Superman used the earth's gravitation pull to allow him to fly faster than light (which is why we see him flying into his own image from the previous orbit resulting in the stretched out "bands" of Superman image that we see circling the planet) allowing *him* to go back in time so he can save Lois.

      Because this shit is important to remember when discussing FTL neutrinos in real-life science. I think I've been nerdbaited.

      1. Grease Monkey Silver badge

        The explanation given by one of the films makers at the time of the film's release was that Superman simply flew backwards around the planet several times in order to go back in time by the simple expedient of crossing the international dateline backwards. Which of course wouldn't work.

      I think you're missing the point...

      It's not a question of breaking the Cause and effect, but in explains why something appears to be moving faster than c, the speed of light.

      In the other article i was trying to explain how it's possible...

      Here in this article they talk about representing 3Dspace as the surface of a paper. If its flat, and nothing can move faster than c, all things will hit the target at the same time.

      But what if the paper wasn't flat?

      Now the laws of physics still have light, gravity etc moving along the paper's surface.

      Again taking the same amount of time. But if the neutrinos still moving at c aren't restricted to moving along the paper's surface, you will see them hitting the target sooner than the photons.

      The question is what is causing the surface of the paper to bend?

      My bet is gravity.

      1. Anonymous Coward
        Anonymous Coward

        Huh?

        Space-time is already bent by gravity. Einstein wrote quite a lot about it. It's long-established.

        The concept that neutrinos are short-cutting via higher dimensions suggested by M-Theory has also long been on the table. Simply stating 'they're taking a short-cut through... um something' is exactly the kind of 'this isn't going to be solved by suggestions on Twitter' kind of comment that Dr. C was referencing.

          "Space-time is already bent by gravity"

          Noooooooooooooooooooooo !

          That's not General Relativity - it's almost the opposite

          The presence of matter & energy curves spacetime - the effect of moving through 'bent' spacetime is *perceived* as a fictitious force called gravity.

            Gravity is a force that acts on mass, which may or may not be an 'frictive' effect of motion through the Higgs field. Either the Standard Model is bang on or it's way off.

            If what they are observing at Opera is a real effect and not due to systematic or statistical error it could provide an insight into experimental designs to test M theory - which is exiting.

    Not a scientist but, aren't neutrino's really small, like sub atomic particles? which would place them in the quantum area of physical laws, which don't function at all like Newtonian physics and pretty much do their own thing.

He then proceeded to give the clearest explanation I've seen of why faster than light information transfer would break cause and effect (if Einstein is correct).

    Check your facts please author

    " Fellow scientists in November claimed to have disputed the faster-than-light Neutrino findings – after the CERN OPERA physicists that produced the results had themselves run them again just to make sure."

    That's not true. The results disputing the finding were published in October BEFORE the second experiment by OPERA. In fact the results for the energy of the Neutrinos is from the same experiement that first produced the faster than light result. The results were re-published in November so they appear to have been after the second experiment, and the media have jumped on them. The results are from the same data as the first experiment. They have no bearing on the result of the second experiment. They don't disprove the result anyway, just add to the pile of questions surrounding this event.

      >"It's the foundation of cause and effect, and dictates that when throwing a brick through a window you see the movement of the brick through the air and towards the window before the window shatters – not vice-versa."

      The principle of cause and effect is a lot older than Einstein, and relativity showed how it was in fact dependent on your frame of reference and that the same two events could occur in one order in one frame, the other in another or be simultaneous as seen from a third.

      >"Space-time, according to Einsteinian thinking, puts the 3D world of space on a flat plane along with time to calculate the way we observe events."

      "Puts the 3D world of space on a flat plane"? What is that even supposed to mean?

      >"Ninety-nine percent of the energy in a dying star is emitted by neutrinos, but it is light that has reached the observers on Earth first, not neutrinos"

      No, the neutrinos reached here first - the light has to struggle its way up through the infalling dense outer layers of the collapsing star, where the neutrinos just sail through it without interacting. The problem is that the neutrinos only got here four hours ahead of the light, rather than the four years we'd have expected if they were travelling the same amount faster than light that the OPERA measurements suggest.

      This was not a good day for the public comprehension of science. The article attempts to simplify matters for a lay audience but just ends up getting them flat wrong.

    tosh - wikipedia science

    The problem with all of this is that it is complete tosh. The theory of special relativity (and clasical mechanics) has 3 possible outcomes

    1) something travels slower than light and would require infinite amounts of energy to get it to light speed (ordinary mass)

    2) something is stuck travelling at the speed of light (photons)

    3) something travels faster that light to start with and can never drop below light speed without destruction.

    It happens because in classic mechanics you can have a negative velocity that is the squared (basic kinetic energy) therefore making it a positive so at lower than light speeds the energy of the particle would be negative, e.g. non-existent which happens quite a lot in theories like dropping to absolute zero where a particle has no energy so can have no mass. It's perfectly possible to travel faster than light but only if one starts faster so in "the real world" one would require negative energies and mass. Possibly CERN generated neutrinos of this type but probably not. How is light altered by gravity in the parallel plane if gravitons aren't particles faster than light ? (and so giving use the red shift used to correct astronomical observations to give us an idea of the make up of stars). Just because no theoretical model has predicted that a neutrino could be created starting off faster than light doesn't mean it couldn't have happened. Stating that something is "impossible" based on a theory is a dodgy starting point for any discussion, otherwise we'd still be stuck with Newtonian mechanics. Best to see if the experiment can be replicated by a different lab.

    I blame the media and the second paragraph of wikipedia on lightspeed myself.

    Relativity and speed of light

    I am getting sick of all this stuff that relativity says nothing can go faster than light. IT SAYS NO SUCH THING. What it does say is that nothing with a none zero rest mass can be accelerated through the speed of light, which is something entirely different. So photons which have zero rest mass always zip around at the speed of light, things with real mass can never get to the speed of light, and if we can ever find anything with imaginary mass they can never slow down below the speed of light.

    Finally anything that can warp space time could take a short cut and appear to be moving faster than light to an observer while never actually doing so.

    1. DJO Silver badge
      Headmaster

      Relativity blah blah blah

      "nothing with a non zero rest mass can be accelerated through the speed of light"

      Close but no cigar, it should be "to" not "through" or more pedantically:

      "nothing with a non zero rest mass can attain the speed of light"

      because saying “through” implies that it can be reached, which it cannot.

      Here, do the maths yourself:

      M (motion) = M (rest) / SqRoot( 1 - (v^2 / c^2) )

      Where M = Mass, c = Speed of Light, v = velocity, ^2 = squared

      This shows an object approaching the SoL gains apparent mass until at the SoL it has infinite mass, beyond the SoL the mass becomes imaginary which may cause some problems in the real universe (or possibly not).

      So yes nothing can (or at least should be able to) move from moving at the SoL or above or below it to any other one of the 3 states.

      As for “short cuts” like warping or hyperspace or infinite improbability drives or Harry Harrison’s splendid Bloater Drive, bring ‘em on, with any luck one of them will actually work.

      Assuming the equation is correct and there is a vast body of empirical evidence to support it, we can say for certain that nothing with mass has been accelerated to the SoL because the gravitational effect of an object with infinite mass would be noticed, the destruction of the universe would be a subtle clue.

      1. Just Thinking

        Imaginary mass?

        What is all this imaginary mass business?

        Imaginary numbers were invented by mathematicians and turned out to have some interesting properties and practical applications.

        They don't tell us anything about the physical world.

        Just because an equation has a square root in it doesn't mean there is some special undiscovered physics with imaginary properties. Would an object have negative kinetic energy if it was travelling at an imaginary velocity?

    AC doesn't understand General Relativity...

    ... which claims that moving clocks tick slower. This has been proven with the GPS system as their clocks have to adjust for the high speed they are travelling at when orbiting around the earth.

    However, the two assumptions that particles with mass cannot travel faster than light and that the speed of light is constant are very difficult to prove.

    1. Poor Coco
      Thumb Down

      “High speed”?

      While a satellite may move quickly compared to, say, a car, it is FAR FAR FAR slower than relativistic speed.

      The relativistic time compensation required for GPS relates to the fact that here, deep in Earth’s gravity well, time runs more slowly. Has nothing at all to do with the motion of the satellites.

    Bad Science

    Obviously they are going to question any observations that challenge current theories, but it seems to me that the scientific community is going out of it's way to explain away these inconvenient findings. Surely what they should be trying to do is simply explain the findings and if this causes them to modify Einstein's theories then so be it.

    The surprise to me at least is that they are not embracing these findings as something that opens up a whole new field of research. After all this would mean more funding and job security. Plus of course a chance for somebody to make a big name for themself. After all there would surely be lasting fame for the person who proved Einstein wrong.

    It seems we have a similar problem here to the one we have with global warming. Too many people are treating Einsteins theories as articles of faith.

    Question everything.

    1. Chemist

      "trying to do is simply explain the findings"

      Oh, good grief !!

      What they will be doing first is to try and duplicate the finding, preferably somewhere else with different equipment

      Measurable and repeatable are two key words here.

      When someone claims to invent cold fusion, the scientific world does not immediately run around going 'yay' and fist-bumping. Nor should you do the same with any other finding which defies both current theories and other experiments which were designed to test the same thing. The speed of Neutrinos has already been measured and found not to break the speed of light; which is why people are first looking at experimental error.

      If I were to claim to have turned wine into water, would you 'embrace it', or would you say 'ok... show me?'.

      You ensure that there is no experimental error, and you repeat the experiment. At present, people are repeating the experiment, and attempting to find any experimental errors.

      The world of Physics is doing it's damnedest to open up new fields of research. Thousands of people in the field will be over the moon if the findings are true. But running around saying they are without repeating the experiment is just the kind of bad science that you are labelling the converse as.

    Just had a thought - If nothing can speed up to the speed of light without requiring infinite energy, how the hell do torches and light bulbs and lasers etc work?

      I think you're confused.

      Obviously light does not have infinite energy! Photons (light) have negligable (infinitely small) mass which effectively allows light to be so fast. It is arguable whether photons have any mass at all.

              basically, the central tenet of special relativity is that the speed of light (ie maximum speed, also called C) is fixed for all observers, everywhere, no matter what they are doing, or how they are moving.

              so your question about what happens when two masses / observers are moving toward / away from each other at close-to the speed of light has some interesting consequences. If both observes always agree on what the maximum speed limit is, and neither of them observe the other going faster than it, ... then they must disagree on how the other is experiencing time.

              (and when you start looking at other equations, you see that mass, and even length are effected by travelling fast,... but not the speed C).

              look up "time dilation" in youtube. there are over a thousand videos.

    RockStar Physicists Have No Clue

    So physicists have no idea why the speed of light is the speed limit. Was it a guess all along? It sure seems that way, doesn't it? Otherwise, they would know that the neutrino FTL result was in error and the whole nonsense would have never made the news.

    Truth is, if physicists really had a clue about the nature of motion, they would know that the speed of light is not just the fastest speed in the universe but the *only* speed in the universe. Nothing can move faster or slower. A body that seems to be moving at a much slower speed than c is really making a series of quantum jumps at c, with lots of wait periods in between. This is true no matter how smooth motion appears at the macroscopic level.

    And if physicists really understood the causality of motion, they would also know that we are moving in an immense lattice of energetic particles without which there could be no motion. Google "Physics: The Problem with Motion" if you really want to understand motion. Believe me, you don't understand motion even if you think you do. And while you're at it, Google "Why Space (Distance) Is an Illusion" for more surprises.

The reason is simple: if the lattice was 3-D, it would quickly run out of energy because the lattice particles interact with normal matter and are jettisoned from their positions of origin and sent flying in all directions. Empty areas would be created everywhere and this would drastically diminish movement. This is not observed. Therefore, in order to keep the observable 3-D universe moving and doing its thing, it must be refreshed with a new lattice at every instant!" - You

      You do realise that many of the denizens of this place are scientists, engineers and other sorts of folk you can't abide?

      Some standard steps in science according to the world at large:

      1) Make a new observation. Check it.

      2) Get other people to see if they can see it too

      3) Postulate an explanation for what you've seen. Check it.

      4) Get other people to see if your postulated explanation works with their related, or independent observations

      5a) Try and make a prediction using your explanation that differs from prevailing explanations - see if it happens

      or if 5a not possible

      5b) Use your explanation and existing data to attempt to accurately post-dict real events

      6) Repeat 5 until dead, retired or bored of the topic

      If you fail at any point, go back to 1)

      Scientific method according to Louis Savain:

      1) Have a particularly vivid dream

      2) Convince yourself that it is both right and obvious

      3) Have a quick google to see if you can find any off-the-cuff remarks from long-dead philosophers, natural philosophers or scientists that don't entirely contradict your dream

      4) Publish (NB self-editing for blatant contradictions is not only optional, but to be discouraged)

      5) Slag off anyone who contradicts you

    But but but...

    Isn't all speed relative? There's no absolute zero-point of speed to measure anything relative TO is there?

    In the LHC, for example you bung some particles in opposite directions round Ye Ringe at 0.8c, say but doesn't one particle 'see' the other (or not, thinking about it) approaching at 1.6c? Relative to itself, of course, but all the same...

    So is it then impossible for any object in the universe to 'see' another approaching it at >2.0c ? (obviously photons travelling head on to each other should be at 2c relative).

      but^3

      So many words, so little understanding!

      Look up "Time Dilation" - Here's a quick précis, as velocity tend towards the SoL time slows. An object such as a photon moving at the SoL is not subject to time at all so from the perspective* of a photon the whole universe is stationary.

      Nothing is "obvious" in the quantum world!

      *Apologies for the anthromorphication of the photon but at twenty to five on a Friday I’m never going to bother to explain it properly.

    2. Poor Coco
      Boffin

      That is essentially it...

      Since there are many effects involved with relativistic speeds (time dilation, length contraction, mass increase etc.) the observer sitting on an LHC proton at .99999c would see the other photon (which, to the boffin in the control room, is also moving at .99999c) approaching at, say, .999999999c or so — but still possessing the appropriate amount of kinetic energy.

      However, it is NOT true that massive physical objects can’t APPARENTLY move faster than light w.r.t. each other; the expansion of space itself, which results in the redshift of distant galaxies, results in APPARENT motion at speeds greater than c if you look at points more than about 20 billion light-years away. This is further than the 14-or-so-billion-light-year limit imposed by the fact space was opaque for a while after the Big Bang; but it is nevertheless accurate.

    3. Chemist

      "universe to 'see' another approaching it at >2.0c "

      Worst than that.

      The two proton beams at the LHC each almost travel at c. To an observer outside the beam it appears that the closing speed is ~2c, but to an observer traveling with a proton the closing speed will always appear to be <c

      It's one of the reasons relativity always appears so bizarre to non-relativitists Worth looking up 4-velocity.

    The whole space/time/lightspeed connection is just wrong and physicists need to wake up like their forefathers before and admit they were wrong, again.

    The speed of light is just that, a speed. There is no universal rule saying that just because a photon in a vacuum travels at 'c', nothing can travel faster. Bollocks. That's just what our current, limited undertstanding tells us and what the maths says - the very maths that was created from what we currently understand to describe and 'prove' what we currently understand!

    Time is not linked to the speed of light, whatever the rules currently say. Why should it be? Now, observable time, that is linked to the speed of light since we are limited to obeserving and measuring anything by that speed maximum but just because something travelling faster than 'c' would appear to act strangely to us and to any measurements, it is not really changed at all.

    Just because something may appear to arrive before it was sent doesn't mean it travelled back in time. It did arrive after it was sent it's just that any observation or measurement of when it was sent is limited to 'c'.

    Clocks in orbit losing time as evidence of time dilation? Absolute proof that they have experienced time dilation or just proof that atomic clocks can run slower in certain conditions?

    As to "Why Does E=MC2" - Of course it does, it was 'created' to do so just as any equation you think up linking one existing value to another newly created one via a large constant. It simply equates energy with mass. Energy is mass except that they wanted energy to be a very large number so they decided to multiply it by the square of c. There is no connection between energy and the speed of light beyond this equation. It's a bit of a con really and nothing special.

    there is nothing particular in this discovery

    The relativity theory stated an upper limit for speed correctly, according to the observations. Einstein`s big failure was to state that light itself possesses this maximum speed. No clear evidence proved this, although the two speeds are very near to each other.

    Neutrinos are just more closer to the maximum speed, but we still don`t know if they reach it or not.

    I'm not qualified to talk about Quantum/Relativity theories as I don't have a Twitter account, but that won't stop me...

    The thing I find slightly irritating is that some 'experts' are too often cock-sure that 'facts' are static - but they aren't. Facts (or 'truth') are relative (sorry) to our understanding at any one moment in time. Scientific history is littered with 'immutable facts' over the centuries (earth is flat, thylidamide is safe, Norwich will never make it to the Premier league).

    Knowledge is always constrained by the bounderies of our understanding. As our understanding expands, so does our knowledge. It may not be verbally elegant, but adding "... to the best of our current understanding" to the end of every 'factual' comment by an expert would be more accurate.

    And wasn't Brian Cox just saying that *if* these incy-wincy particles were travelling faster than light, we would just need to adjust our understanding and come up with an alternative theory that explained all the 'facts' as we see them? The world won't end... well, not for ages.
