The truth is...

It's impossible to write a program in Pascal that will loop forever.

#Earth #forever #loop #universe

@Pat wait huh?

while true do
begin
// loops forever.
end;

@freemo

Forever?

@Pat Forever. it turns your computer into a perpetual motion machine and even if you pull the plug it continues to run anyway because it cant shut down the loop so it starts pulling energy from zero-point fields.

@freemo

That's a quantum computer, right?

@Pat my computer is sub-quantum. It uses quarks and the strong nuclear force rather than electron spins and EM force. I figure while everyone else is wasting time trying to build quantum computers I'd just skip ahead to the next gen.

@freemo

When I used the term "sub-quantum" the other day, I was being facetious but I just searched and it turns out some folks are using the term legit.

I thought this out. If we're in an open universe, everything cools down to nothing and all information is lost. But if we're in a closed universe, it collapses to a singularity and all information is lost. So, either way, the program has got to stop at some point.

And if we ever figure out how to control time and run the program within a temporal loop, it still doesn't run forever, it just runs during the fixed amount of time in that temporal loop an infinite number of times.

There's no forever.

@Pat singularities, or what you really mean is a black hole, does not cause the information to be lost. It persists as a hologram on the event horizon.

@freemo

I'm familiar with the hologram theory (or theories). I don't think it applies to the collapse of the universe. It's a theory about black holes, which is different.

@Pat depends.. 1) the universe is theorized to be little more than the inside of a black hole... 2) if there were a gravitational collapse of the universe it would form a black hole, so data would be preserved. 3) if there is a topological collapse, where spacetime itself shrinks, a reverse of the big bang, then yes you'd be correct blackholes wouldnt form.

@Pat Actually I kinda take back #3.. even a topological collapse would result in blackholes.

The reason blackholes didnt form in the big bang/inflation was due to uniformity which didnt disappear until things were too far spread out to collapse. But in reverse things are no longer uniform and thus I would expect them to collapse into lots of blackholes if the universe collapsed.

That said I'm no expect on these things, at best its an interest of mine. So I would defer to people more comited to this subject.

@freemo @Pat is this why we topologically sort
