sourceAre We Alone in the Universe?
Richard A. Kerr
Alone, in all that space? Not likely. Just do the numbers: Several hundred billion stars in our galaxy, hundreds of billions of galaxies in the observable universe, and 150 planets spied already in the immediate neighborhood of the sun. That should make for plenty of warm, scummy little ponds where life could come together to begin billions of years of evolution toward technology-wielding creatures like ourselves. No, the really big question is when, if ever, we'll have the technological wherewithal to reach out and touch such intelligence. With a bit of luck, it could be in the next 25 years.
Without FTL travel (or at least communication) I've always found this highly doubtful. It's a popular science fiction concept, but physics (as far as we can tell so far) doesn't support it.No, the really big question is when, if ever, we'll have the technological wherewithal to reach out and touch such intelligence.

Scientific discovery and mechanics is accelerating at the speed of imagination. We'd better hurry up though, with our closest planet-ful neighbour being 90 LY away.chcr said:Without FTL travel (or at least communication) I've always found this highly doubtful.

means indeed we shall answer them.
Evidently because Q hasn't fucked with it yet.so Chicka-pet, why can't stuff arrive at it's destination before it leaves it's point of origin, if it isn’t traveling through normal space time?
Imagine how fast light 'could' go if it didn't have to stop and wave.Winky said:Hey Dood I ain't gotta clue!
That's just it we don't know, yet.
So if space-time is indeed infinite
and there isn't anything 'outside'
of it and the absolute speed limit is
299,792.458 kilometers per second
then fine I'm sure we can have a real
funtime nevertheless.

C'Mon you craggy old codger!
One hundred years ago all the things we take for granted today would have seemed like science fiction or the work of the Devil.
500 to a thousand years from now danged near anything might be possible. We might even have answered most if not all of those questions on the list Hell we might even BE Q by then Heh heh heh.
Just not in this universe.Actually - its not proven that we can't go faster than light...
Sorry, quantum theory allows for the possibility but that's as far as it goes so far. No such have been proven to exist.several things do.
Well, that's substantially correct, but do you understand why? In relativity equations, mass becomes infinite at the speed of light. How do you continue to accelerate infinite mass? This is why you need "hyperspace" or "warp-drive."We just can't accelerate TO the speed of light.
Its the part of the theory of relativity which people often misunderstand.chcr said:Just not in this universe.

I hope you made that up because if it's from a textbook, it's a little simple. No, the photon or photons do not (in fact cannot) exceed the speed of light (in a vacuum) in normal space. What happens is it disappears (from normal space anyway). Matter is annihilated at the event horizon of a black hole (hence the xrays), why not light? The simple fact is that anything that happens past the event horizon of a black hole cannot be described in terms of normal space because all equations involving speeds faster than light involve the square root of -1. Maybe you know what it is, I haven't figured it out yet.MrBishop said:Its the part of the theory of relativity which people often misunderstand.
Here's a nice theorum for you. Light curves because of gravity, light slows because the medium through which it passes. If a beam of light is heading towards a black hole (from which light cannot escape) does light accelerate as it gets closer and closer? From 186k mi./sec to lets say... 300k mi/sec?
If so...what is the 'real' speed of light? Can light be stopped if it finds itself at a black hole's nodal point?
I think that it's only a matter of time and a huge chunk of fluke-luck before we figure out how to use those questions to our advantage. Maybe not in my lifetime, or my son's...but eventually.
Part of it was made up...part of it is from a brainstorming session that I heard at Mensa.

we can guess or calculate what happens
Hell...I can barely wrap my brain around some of the math to describe our own universe (let alone tax-forms). I'll leave the imaginary numbers stuff to the uber-geeks.chcr said:Well, we can guess. Calculating would once again involve that -1/eleventyseven. I understand a lot of math, but I just can't get around imaginary numbers. My sense is that they describe other universes (other realities?), but until someone shows me one I'll withhold judgement.![]()
