They would form one bigger black hole, though the mass of the new black hole would be less than m1+m2.

black hole =/= worm hole

now wikipedia black hole

now think about it for a second

now delete this thread

>>6944433
Why x<m1+m2?

2 colliding black holes give birth to your moms anus

>>6944443
some energy is liberated during the merging

pents speak truth

>>6944421
collision is incredibly unlikely.
they may orbit each other and then throw away from each other

>>6944453
black holes pull things toward them though?

wouldn't they pull each other together?

>>6944448
Ah thanks

>>6944459
The closer to things orbit to each other the faster they orbit so if their velocity overcomes the force of gravity they will be flung away.

>>6944459
black holes are not magical vacuums. if you have a star with gravity X, and a black hole with gravity X, they will both "pull" the same strength at the same range. black holes happen because they are EXTREMELY massive.

two black holes getting close to each other would behave the same as two other extremely massive objects getting near each other. generally a huge calamity for anything nearby.

if you deliberately threw them directly towards each other, who knows. probably nobody on this planet.

Specifically, it's supposed to be released in the form of gravity waves.

>>6944453
If the singularity of the small black hole went beyond the event horizon of the larger BH, but kept orbiting faster and faster, could it manage to escape?

>>6944761
>gravity waves
What is that exactly?

If we orbited two black holes that collided and sent out a "gravitational wave", how would we experience that? An influx in our gravity temporarily?

>>6944771
No. Remember that the event horizon represents the point where the escape velocity starts exceeding the speed of light. It just isn't possible to orbit faster and faster.

>>6944775
It would be a series of waves released as they coalesced (see pic). I suppose it would be like a vibration. Gravity waves still haven't been conclusively experimentally confirmed though, so it's still hypothetical.

>>6944810
I guess another interesting thought is how fast would gravitational waves travel? Would they be limited to the speed of light?

All I wanna know is what the goddamn composition of these things are.

A star collapses and turns into a black hole, but that shit isnt just a real tiny star in there. What does this shit turn into, what composes it, why exactly do they emit all this crazy radiation, what processes are converting the matter to radiation.

nigga what the fuck inside that black hole doe

>>6944821
Yes g waves travel at C

Nobody knows. It would basically be like dividing by zero.

>>6944448
>some energy is liberated during the merging
How is energy going to escape faster than the speed of light?

>What does this shit turn into
Matter. A star is just atoms and particles going crazy as plasma. A Black hole wouldn't be any different, just waaaaaaaaay more dense

.>what composes it

All kinds of matter and elementary particles. Think a huge chunck of atoms in one dot... sorta.

>why exactly do they emit all this crazy radiation

It's not exactly the Black Hole that emits radiation, because radiation can't escape it. It's the energy on vacuum that generates pairs of paticle and anti-particle, then one of them gets sucked in the event horizon while the other escapes and reaches our sensors.

If you have any sensors that have detected that Hawking radiation go claim your Nobel prize.

What we detect is matter falling into the black hole heating up and emitting radiation.

>>6944941
Cosmic radiation has enough energy to create miniature black holes in the upper atmosphere, they destruct immediately by Hawking radiation.

>>6944897
So it doesn't depend on the strength of the gravitational field it's traveling through? Like a sound wave traveling through matter?

>>6944935
>A Black hole wouldn't be any different
No it's very different.

Look at neutron stars compared to regular stars. Black holes form when the gravity is so strong that not even a neutron star can support its own weight, there wouldn't even be electrons or protons in a black hole, as they would have collapsed inward two.

In other words we have no fucking idea what matter in a black hole is like. All we can basically say is that it isn't teleporting/traveling anywhere (like a wormhole) as the black holes gravitational field isn't getting weaker.

>doesn't know about quantum tunneling

>>6944421
This is amazing!!! You know what lies behind the event horizon of a black hole, please share this!

>>6944436
not op but..
what would happen if a worm hole collided with another worm hole?
