I can tell with certainty, but I'm not gonna discuss my mother's dieting problems here.

Where did energy come from to move a universe? Presumably the big bang. And what happens when that energy runs out?

Then inertia happens. And before you start with gravity, the entire thing is pretty gravity-defying to begin with.

[Descan]

Things stop accelerating.

Of course, velocity doesnt require energy, so they'll continue moving apart. And if they're far enough apart? Gravity would be unable to pull them back together.

Couldn't put humpty dumpty together again"

Perhaps then, that would form a much bigger form of singularity, and then energy would (Somehow) be built up over millenia and another big bang occur.

Or perhaps there is an outer limit to the universe, and when it is reached everything will rebound.

By "runs out" I am assuming you are referring to a state of absolute entropy, the "heat death" and not the energy being destroyed in a direct opposition to the laws of thermodynamics?

[TD1]

I know that energy can neither be created or destroyed. I meant it would cease to be kinetic.

That scenario has...potential.

Wow. Lol. I thought I was the one who used terrible, terrible puns

Latest experimental data suggests that the universe is accelerating thanks to dark energy (which granted is not fully understood), which suggests a cold, dark fate for the cosmos.

Luckily not in our lifetime. As a species.

Preaching to the choir, man. TBH if we even make it through the 4bil years until the sun goes all omnomnom I will be surprised. If we make it that far though, we should be long gone out of the solar system, and probably far removed from the bipedal stacks of meat we currently are.

I like to think that the expansion of the universe is like zooming into a fractal.

It's expanding, always has been expanding, always will be expanding. There was no 'big bang', is no god, just new particles popping out of the quantum foam like graceful spirals from what appeared to be a single pixel of a Mandelbrot set; with our wiewport limited by the speed of light.

I like that idea, but it's probably not true.

Aren't we supposed to run into another galaxy at some point in the astronomically near future? Forget how far out that one is...

I can guarantee that our view of the Universe will change completely in less than 50 years.

Andromeda. And yes, in about 3 billion years.

Yeah, we are due a merger with Andromeda conveniently in around 4billion years, just as the sun does its middle age spread... not because we are moving in "different directions", rather we are both moving away some "somewhere" (whatever that means in a cosmological sense) at different relative velocities - Andromeda is closing at around 100 km/sec. Though seeing as the stars in each galaxy are sufficiently spread it is highly unlikely there will be any colliding going on, rather a big fuck off gravitational smearing into some kind of mega-blob galaxy. Within the solar system, you probably would not really notice much happening, save for a few more stars in the sky over a few million year period
