So what kind of a partical is the partical that escapes from a black hole is it a photon, electron, a quark ?
I really want to know
usually photons. this may seem unintuitive because photons have no antiparticle loosely speaking, but strictly speaking photons are their own antiparticles.
since photons have no charge to begin with, all that needs to be conserved is momentum, which is conserved as both particles move in opposite directions (one towards the singularity, one towards infinity away from the event horizon)
Thanks

So you are saying black holes aren't actually black? Just very dark.
>>9091235
No, they're black because Hawking radiation isn't real
>>9091235
Nope, they're black. Hawking radiation come from slightly before the horizon of event, which is the actual frontier of the black hole.
Also, they generally have a lot of matter orbiting aroung, which radiates due to heat and is quite visible, and we have trouble to distinguish Hawking's radiation in it.
So, the black hole, in itself, is black. But its surrounding isn't.

>Hawking radiation come from slightly before the horizon of event, which is the actual frontier of the black hole.
Yes, but photons are coming out of it, not necessarily from within but close enough. And terribly redshifted, but still photons.

Wouldn't any photons produced at the event horizon remain trapped in the photon sphere? In essence the matter/energy mass of the black hole remains the same. It's just moving outside the event horizon.

Yes but by design this happens just outside the horizon so it's not trapped.
>>9092354
By whose design
>>9092354
The photon sphere of a non Kerr hole is I think 1.5 times rs? If so how can photons created at less than that travel outside that? Every photon created at the horizon travels along an arc that reintersects the horizon or circles endlessly around it.

Hawking radiation doesn't real.

Is the explanation to why there is more matter than antimatter the universe really as simple as "black holes?"
