Heat death isn't the end of the universe?

No. Things merely get very boring and increasingly entropic.

Considering that universe, like a corpse, will essentially do nothing ever again...

Untrue. You can run a simulated universe (or universes) inside it for an infinite timespan by gradually lowering the clock speed on the simulation (nobody inside can tell). Freeman Dyson did the math.

ooo, that is... awesome.

I like this thread.

While we're discussing fates of the universe, whatever happened with the whole "Bip Rip" theory?  I know it required the strength of dark energy to increase over time, or something of that sort, but I haven't heard anything new about it despite it being a seemingly big deal a few years back, and I haven't heard that it's been entirely ruled out either.  Anyone know of new information/data regarding the Big Rip?

Speaking of which, http://www.aleph.se/Trans/Global/Omega/dyson.txt. Or just search for Eternal Intelligence on wikipedia.

So I was thinking about quantum immortality and I was wondering if the same would apply if you died in your sleep or other state of unconsciousness.
yes or no? why or why not?

This is also really cool:

In the description of the quantum immortality gedanken experiment, a
physicist rigs an automatic rifle to a geiger counter to fire into him
upon the detection of an atomic decay event from a bit of radioactive
material. If the many worlds hypothesis is true, the self-awareness of
the physicist will continue to find himself alive after any length of
time in front of his gun, since there exist parallel worlds where the
decay does not occur.

On a microscopic scale this is analogous to the observing a reality in
which the second law of thermodynamics does not hold. for example,
since there is a non-zero probability that molecular interactions will
result in a decrease in entropy in a particular sealed volume under
observation, there exist histories in which this must be observed.

This is never observed. Therefore the MWI is shown to be false.

That's not cool at all! It shows I'm not really immortal D:

[Topgun]

I don't want to be immortal if it doesn't mean I would be forever young and healthy.

Flawed logic. It assumes that there are only two universes, the one where the physicist gets shot and the one where he doesn't. If every single interaction causes the universes to split then there would be billions where the scientist got shot for every single one where he didn't.

So it could simply be that we haven't had enough people shoot themselves to prove it is wrong.

well its actually flawed for other reasons too. He isn't taking into account the entropy needed to set up the devices and the fact that the second law is probabilistic.
