Even black holes will die

[frigidweirdo]

This hawkings radiation is just brilliant
All BH actually lose mass by quantum mechanics and Emc2
The gravitational energy is so extreme that particles pop out of existence outside the event horizon .
It’s always paired ones and one goes back into the black hole and the other goes away from it
So even black holes will evaporate and die

Racist. Only white holes will die. Black holes will live forever.

But yes, in theory everything in the universe will die. The universe is expanding, which means it'll probably contract at some point and go back to another Big Bang. Or maybe it's expanding AND contracting at the same time.

All the evidence points to rapid expansion and death by ice

Firstly I doubt all the evidence points to this. Some of it might.

Secondly the evidence we do have probably makes up about 0.000001% of what is actually out there....

All the evidence shows this 100 percent due to the mysterious dark energy

What?

So, there's evidence that the universe will only expand and will not contract? I'd love to see that evidence.

Curious Kids: will the universe expand forever, or contract in a big crunch?

Pretty much as soon as we understood what galaxies were, we realised they are all moving away from each other. And the ones that are further away are moving faster. In short, the universe is expanding.

The problem with this is that A) we don't know what shape the universe is. B) We don't know what's outside the universe. C) we don't know how the universe functions.

So, to say "hey, if we throw something at 11KM a second it'll get out of Earth's orbit, isn't the same as saying "if we throw a galaxy at X speed, it'll continue to expand forever."

For example. Imagine the universe is a bike inner tube. At one point in the inner tube someone has put a ring around it and the space for everything to fit through is the size of one atom.

Then we blow the air through the inner tube forcing it to all go in one direction.

If the universe is the same then as the matter and time moves away from the big bang hole, then it's expanding. But it's also heading directly for the big bang hole. So, it can't expand forever because the space in which is can expand will, at some point, not be much space at all.

And that's just one possibility. There are billions of possibilities.

This is the consensus by the wise men

Which means nothing. "wise men" who know nothing are just as wise as anyone else.

Literally no one knows what will happen to the universe. There's no evidence for it. There's guess work, some more guess work and some pouting maybe. But no evidence.

They can measure the rate of expansion by its speed caused by dark energy

But we're not talking about just expansion, are we?

Just because something expands, doesn't mean it'll do it forever.

We don't know the shape of the universe. It could be that it goes around and then ends up back where it started. Knowing it's expanding doesn't help us know that.
