When this happens near the event horizon of a black hole, one of these particles call fall in, stopping them from annihilating.

• The escaping particle is hawking radiation. ultimately the mass of this particle must come from the black hole, so over eons black holes...

So what will happen with black holes as the universe ages and dies around them?

• Again, we don't know but we have some ideas based on our current understanding of physics: Hawking radiation.
• In quantum field theory the vacu...

• ….. was a star so massive that it had collapsed in on itself.
• It’s so massive that not even light can escape its gravity, which is why it’s almost perfectly black.
• It’s gravitational pull is so powerful, it warps and distorts not only light but also...
