do you think it would ever be possible for 2 black holes to meet? they say they are growing.. which makes it highly probably they will have a meeting one day.

i don't think anything special would happen other than they merge basically. but i had been thinking because of what they eat, what if one day a black hole has consumed to much...

like a pressure bomb, eventually it'll all be to much. what do you think

A blackhole already is what happens when a star 'eats too much' it is a pressure bomb in the sense that the gravitational force is so extreme it generates a singularity. Even if a blackhole consumed all the matter in the universe it has already broken down the laws of physics by it's mass as much as possible, so it would just take a very long time to evaporate via its Hawking radiation.

Well, it stops "evaporating" at a certain mass. Not that Hawking radiation is proven

No it doesn't. The evaporation occurs on scales longer than the age of the universe where the mass is greater than one solar mass, but eventually they entirely dissipate.
>>Not that Hawking radiation is proven
It's got a lot of data behind it, it seems to be a necessary component of black hole dynamics. To be fair, black holes aren't even proven, they are theoretical objects that have never conclusively been observed.

You realize we confirmed gravitational waves when LIGO detected the waves caused by two black holes coming together and eventually combining, right?

I posted a thread about that when it happened. This board is so fucking slow, it's still there >>56038

But that presumes there is an unlimited amount of radiation in the interstellar medium. By the time black holes are evaporating en masse, all matter will already have fallen into black holes, so there's no way it could replenish itself with ambient radiation.
