OT: Earth's orbit changing?

But why? Does the universe have an end? Why can we not live forever without fear of being roasted alive by our own sun?

because if worse comes to worse, the Last detterent is fear. that is why the police have guns.

because, atrocities, everything is cyclic.

Is this something from the Matrix?

Well, I tried to think of something that has a beginning but no end, but I couldn't think of anything.

Entropy. The universe began at (relatively) 0 entropy, but entropy always increases without end.

Again this goes back to one of my old topics about how rare life realy is and that that rareness of life is extactly why I feel there are very few, less than 100 or so simular planets to earth in the galaxy that have humaniod type life of one type or another.

I thinkw e closed that one ages ago with the conclusions that
A) "Life" doesn't equal little greeen men but can be a 1 micro meter blob of green goo.
B) Life will be very common in the universe
C) How common intelligent life is is anybodys guess
D) How common humanoid type life is is anybodys guess

We just don't know how much advantage humanoid type life gives to a species... and we really need to if we are to make any resonable assumptions on its rarity/commonness

Well this isn't really true. From a pure physical point of view and if we don't iclude some of the weird new age quantum physics that allows from WEIRD STUFF TO HAPPEN for no apparent reason... the universe has a maximum level of entrophy.

It is when everywhere in the universe the temperature will be the same and when all mass will be equally distributed everywhere in the universe. That is when Entropy will be maximal.

But since the universe is expanding... who knows... the classical entropy definitions don't allow for an "inclosed system" to increae in volume as that would mean that some "External" force would have to act upon it...

[Fyron]

The very fact that the universe is expanding makes it true... if the universe expands, the particles keep moving outwards, thus increasing entropy.
