Even if we somehow achieve 1/100th of light speed, which is orders of magnitude faster than the fastest thing made by humanity, it would still take a long long time to get there. And the chances of any person getting there are null since they would be dead. I suppose we would need a ship that could support itself completely including population wise for hundreds of years. Who would sign themselves and all their descendants up for that?
And no way humanity sees the end of the earth. We'll have been killed by something by then. Probably ourselves.
Pretty much. I think so many people fantasize about living on another planet, but it's just greener grass.

I would imagine that not only is there life somewhere out there, but in many, many places out there (perhaps millions).
This is why I find it so hilarious when people begin speaking in terms of millions and billions of miles, years, etc. as if we can wrap our little minds around such numbers. We're a pretty confident species...

Funniest thing I've heard in a long while..
wake wrote:I remember watching a special on either the History or Discovery Channel awhile back on the seven most likely ways mankind will end. I'm not sure on the order of their probabilites but it went something like-
6) Robots take over
5) A black hole
4) Disease(natural or man-made)
2) Nuclear War
1) Climate change (not necessarily caused by man, could just be another Ice Age)
I forget what the 7th one was but it was an interesting special.
Something along those lines:
Highway 1: Extinction (Highly unlikely, but becoming more probable over great lengths of time unless we find our way to Highway 3).
A. Extinction by Natural Event
(1) Climate Change Has to be catastrophically extreme to achieve total extinction.
(2) Impact by asteroid or comet
(3) Change in Solar Output, resulting in an uninhabitable Earth.
(4) Disease or Catastrophic Pandemic
B. Extinction Through Man-Made Event
(1) Human-Induced Climate Change Once again this would have to be extreme.
(2) Nuclear Holocaust
(3) Man-Made Illness
(4) Unforeseeable Catastrophic technology
Highway 2: Status Quo (This will inevitably deadend at Highway 1 given enough time, unless
a path to Highway 3 is found).
A. Repetitious Rises and Falls
B. Stable civilization held together by some unforeseen social science or social philosophy,
but falling short of the third highway.
Highway 3: Transcendence (Highly desirable)
A. Interstellar Travel, maintaining our present physical form or biologically similar.
B. Transfer of ourselves to an artificial form, capable of surviving independent of our planet and sun.
C. Evolution, either natural or artificial, into a higher biological form able to devise new
and unforeseeable methods of survival.
