Just think that not even 100 years ago, people would probably not be able to comprehend us posting messages/conversing on a medium such as this, or a
cell phone, or a bunch of other stuff we have. Just think what could and probably is out there that we can't even imagine. I mean by 2108 there will
probably be stuff on Earth that would blow our mind. Thats why I don't doubt intergalactic travel and the like is possible for some very advanced
civilizations.

Sorry SoundFX - missed this when I was reading through before.
The point I make about reaching the limits of possibility (which SkyFloating for one quite reasonably disagrees with) is that, there may come a time
where the curve of our achievement, like most curves, flattens out. I put forward the hypothesis that we may be nearer that than we think. Others on
this thread have talked about the idea that we only have 1% of the knowledge that we might have - but they don't offer any evidence that that is so.
Well, they can't really, I suppose - if they knew what it was we don't know, we'd know it, wouldn't we? I'm starting to sound like Donald
Rumsfeld...
It could be said, though, that there is evidence that we
have reached the limits. We know that to traverse great distances in the universe we
need to find a way to move at near or more than light speed - but it may be that the laws of physics prevent us from doing so. We may have reached the
point at which we can no longer break down particles to even smaller constituent parts. We may, as it were, have reached the event horizon of our
understanding.
Many people rely on the idea of superior understanding elsewhere in the universe to protect them from the limits of their own knowledge. If there's
someone who knows more out there, they may help us - goes the theory. I'm postulating the idea that we know nearly as much as there is to know (this
is a postulation, not necessarily my belief, I'm not arrogant enough to believe anything of the sort).
But If that is so, how should we go about dealing with the fact that we will never cross the universe, and no one will cross it to reach us?
