Just welcome our new tea eating alien overlords.
There are billions of habitable planets in the Milky Way where aliens could be having their tea right now, according to a new six-year study. "Our results show that planets orbiting around stars are more the rule than the exception. In a typical solar system approximately four planets have their orbits in the terrestrial zone …
Just welcome our new tea eating alien overlords.
"You'll have had your tea, then?"
Add in the moons around planets in the habitable zone and the number of stars with no habitable bodies should be nearly zero.
maybe they're all too busy playing "Angry Gnarfgles"
They are mostly all looking up at the stars and wondering "are we alone?"
Remember, our own radio signals aren't even all that far out yet. That is, if they can even be heard at all on that kind of scale.
They went digital eons ago, so all our analog transmissions file by as noise.
Basically you think the light is on but no one is home. Bit like Earth then.

It is a set of jump coordinates, converted from another song Kara Thrace's father taught her as a child.
It probably can be reduced to the equivalent of NGC-1252 Tuvan Throat Singers' tonals in an acoustic conduit.
On a Galactica threat/note, I really wish that we are just the descendants of interbreeding, and that our distant relatives are out there, looking for us after hearing of a band of refugees seeking a new home. Wouldn't it be something to have distant cousins "find us". They might come to regret it, though -- if they exist at all.
I'd prefer to believe that if comets brought water to the Earth, then it can and ought to have happened for other worlds. Even if only 1,000 other worlds, even if they are too far for *us* to detect yet. Unfortunately, we may not as a species/world find other advanced life until 5 or 10 more lifetimes from now, assuming they cannot cloak themselves to decieive us into looking elsewhere, assumng they've been approached by others and learned to remain anonymous, hehehe.
To me, it would be sad if we are all there is of sentient life forms. It would be a cosmic waste of the universe's sheer size to have this vast support system of gravity, wells, energy, and so forth, a huge cosmic show, just for *us*. Kinda depressing. I hope there's more, a LOT more life (intelligent, sentient, comparable) out there -- even if we don't get to find out.
oh hang on the forbidden fruit planet is patented...
Out there, in the vastness of the cosmos, there could be completely new and exciting forms of patent trolling and fanboi flame wars.....
“This means, statistically, every star in the galaxy should have at least one planet, and probably more,”
"Statistically, the research team extrapolates that [...] two-thirds have an Earth 2.0."
So now we know that "Fp" is about 1 and "Ne" is 2/3. How does this affect current estimates?
See maccys slightly mis quoted quote 'so where is everyone?'
1) They never made it past our equivalent of WW3 or some other self made disaster
2) They have made it past that stage and are far advanced. Possibly observing. Possibly not
3) Some kind of natural disaster killed them all
4)Their radio hasn't reached us yet and are most likely 'dark' to our listening abilities by now. (We can only measure that which we know how to measure)
5) Space. It's big!
"....I mean really big. You wouldn't believe how big it really is. You may think it's a long way...."
6. Radio of a type capable of detection across interstellar distances becomes obsolete within a couple of centuries of its invention.
We know that's true because it's happening all around us. Analogue broadcasting (with easy-to-detect carrier frequencies) is being turned off. Digital signals are far more efficient, meaning far harder to detect at interstellar distances. Also for how long will radio broadcasting exist at all? The Internet is starting to replace broadcast in developed countries.
I doubt that 22nd-century Earth will be radio-detectable from tens of light-years out, let alone hundreds or thousands. (I'm assuming technological progress continues ... but it's also true if we blow ourselves up).
That's what I meant when I said they had gone 'dark'
And every star where the axis of the planetary orbits is not perpendicular to our line of sight, which is most of them, are missed by transit observations because nothing transits.
@Alan - Fortunately this fraction can be estimated and extrapolated. And we still have star wobble for the others.
Radial velocity will also only catch an exoplanet candidate if Earth is roughly in line with its orbital plane. The gravitational microlensing approach is not as sensitive to the relative geometry, but it will also miss most exoplanets because of the time sensitivity (the exoplanet has to pass nearly between us and the distant star while the near star is transiting the distant one).
It's all statistical; you can make assumptions about the distribution of the angles of rotation of nearby stars, and hence their ecliptic, and you adjust your estimated population of planets based on the maximum number it would be possible to detect with each method.
That the only practical Star Ship designs are really "Generation Ships", We probably could build one or two.
No warp or hyper drive :(
Not even an Ansible yet.
Seems that finding the right star for a destination isn't actually hard - almost any one will do.
Think of all the souls to save, but the 'in God's image' thing may need a reword!
"And other sheep I have, which are not of this fold: them also I must bring, and they shall hear my voice; and there shall be one fold, and one shepherd."
And if you think "made in God's image" means "looks like a monkey" you're really not thinking very hard. This may be remarkably demonstrative.
...of a 'metaphor'? ;-)
... required reading for any one with the specified missionary zeal.
I'm not worried about alien armies - if they can get here, they are either so advanced they will wipe out out instantly, or are so advanced in science they don't need our pitiful resources, and could get what they want far easier in the asteroid belt.
No, what I am afraid of is alien missionaries - "People of Earth: have you accepted Glub as your personal saviour?" After all, look at how well that sort of thing has generally worked out in our past.
to invade another planet is to take over a small number of leaders and opinion formers.
You can then steer the natives towards terraforming (or xenoforming) the planet to make it more hospitable for your own requirements on the planet's own dime, without all the wasteful drama produced by giant invading armies, etc.
Extra points for persuading the natives that none of this is happening, that - for example - temperature increases don't matter, and that possible developments in the wrong direction - like sustainable power - are a bit mad really, and no one should take them seriously.
That way the natives can cook themselves, and you can start eating them when you're ready.
And you've saved me having to actually read any of David Icke's books.
...which is basically what the entire Bible is... admitting an ancient collection of writings, written by dozen of people in the bronze age and arranged by even more obtuse ones during the Middle Age era, has any authority over how we were actually made.
David Icke wrote the bible?
Oh but to be serious, the bible isn't a metaphor. It contains a great deal of metaphor (neatly buggering up the still annoyingly popular "metaphor was only invented in the last 400 years" belief that I keep seeing EVERYWHERE), but it isn't one in total. It's a collection of sociological and historical documents charting the evolution of a set of religious beliefs over approximately 3000 years. Once understood in a correct historical context - and when parts are understood within the context of other parts - it becomes much less obtuse and much more readable.
Well, not readable... but at least understandable. Frankly, the sheer number of misconceptions people have about scripture still stagger me. I' often staggered by how much of it I completely misread.
And now back to Arkham City. Batman keeps dying for my sins, poor chap.
Imagine if they exist and think WE are fugly.
Would that make us the zit of god, or the wart of god, or the cancre of god? For all we know, we could be cysts, pollops, hangnails, and the mites of God's very aged, virtual skin... hahhaha
Again, "in the image of God" doesn't refer to physical appearance.
...but how many of them have Simon Cowell burning holes through their culture?
But poor PH only has one!
This fellow seems to think some of these exoplanetarians are already in our neighbourhood:
My vote is for non-carbon based life forms. Or should that be 'thing that'd be interesting to see'.
The physics of chemistry is universal. There's no other element that has even half the versatility for building complex molecules that Carbon does. Single bonds, double bonds, rings with de-localised electrons, stereochemistry where one carbon is bonded to four different groups or the cis/trans arrangement around a double bond or the sequence of groups around a ring ....
Alien biochemistry may look nothing like ours, but I'll eat my hat if it's not based on Carbon, with Hydrogen, Nitrogen and Oxygen in important supporting roles. I also think it highly likely it'll have proteins (loosely defined as long chains of amino acids, CO-NH bonded).
"The physics of chemistry is universal. There's no other element that has even half the versatility for building complex molecules that Carbon does." -- or at least you hope it does
that your hat is also carbon-based - after all, cannabalism is the name of the game !...
"Scientists have discovered that there are more planets in the solar system than there are stars."
"If the Universe Is Teeming with Aliens ... WHERE IS EVERYBODY?: Fifty Solutions to the Fermi Paradox and the Problem of Extraterrestrial Life" by Stephen Webb.
“perhaps other coincidences in other solar systems have led to entirely different and exciting new forms of life"
Doesn't seem to be said enough i reckon.
You mean like coneheads and tentacled blobs or like Kim Kardashian and Pee Wee Herman?
Or maybe they just all realised taking the time to build complicated space crap to invade other planets isn't as fun as frolicking in the oceans, eating fish and asking the babble fishes for a lift when they need to leave.
the jalopy they're driving is red-lined at 50,000 miles per second.
It appears that everyone's jalopy is red-lined at 1 ly/y, and furthermore you need an infinitely large team of horses to pull you up to that speed, and infinitely large brakes to dump the energy should you wish to stop. Where is everyone? Out there, a long way away, and that's where they're forced to stay.
"I'll have grounds more relative than yours" (pardon the pun)
Until you have more convincing proof of the earth's alien repellent field, I will continue to sleep with the light on. But thanks for sharing.
