Why doesn't Hawking radiation add to the mass of a black hole just as much as it subtracts from it? [duplicate]
If 'quantum foam'-generated particles are made of matter and antimatter in equal amounts, why don't the matter particles that fall into the black hole add to the black hole's mass just as much as the ...

Why does Hawking radiation cause black holes to die? [duplicate]
If a particle is being expelled from a black hole and an antiparticle is being driven into it, shouldn't the opposite occur as well and in the same frequencies?
I mean, black holes should emit ...

How does negative energy from Hawking Radiation cause a Black Hole to shrink? [duplicate]
Hello this is expanding upon a question that was previously asked on stack exchange that I linked below. From what I understand of Black Holes is that overtime Hawking Radiation results in the Black ...

How does virtual particle become real particle in Hawking radiation? [duplicate]
I am new to black hole and general relativity and am just getting introduced to these concepts.
According to my understanding, virtual particle that forms because of quantum fluctuation becomes real ...

Why does Hawking radiation outside the Schwarzschild radius decrease a black hole's mass? [duplicate]
When a pair of virtual particles is created outside the event horizon of black hole, there is a chance for one of the particles to escape. Zero chance on the surface of the event horizon and my ...

Hawking radiation and black hole evaporation [duplicate]
As I understand it, Hawking radiation predicts black hole evaporation because of quantum effects. After the creation of a particle/anti-particle near the horizon of the black hole, if the one gets ...

Why black holes lose energy? [duplicate]
It is often said that black holes lose energy throughout the process called Hawking radiation. My question is, since the process of creating particles is random, why do the black holes captures more ...

Hawking radiation (black hole evaporation) [duplicate]
I understand that one of the simplified ways of looking at Hawking radiation is a pair of virtual particles close to the event horizon (but outside of it). The particle with negative energy falls into ...

hawking radiation [duplicate]
My question is regarding Hawking Radiation and its effect on black hole. Now as we know that particle and particle pairs create at every place in space and it is true near black hole horizon. Then why ...

Why does one particle in Hawking radiation have negative energy? [duplicate]
So as I understand it, Hawking radiation occurs when virtual antiparticle-particle pair are created near the event horizon of a black hole due to vacuum fluctuations because of Heisenberg uncertainty ...

Why does Hawking Radiation not add up to zero? [duplicate]
First off: I am not familiar with the details of quantum mechanics or relativity.
My understanding of Hawking radiation is as follows: Pairs of particles and anti-particles can and will spontaneously ...

Hawking radiation and mass annihilation [duplicate]
Now, i just heard that the particle anti particle pairs that zip in and out of existence every planck second both have positive mass. if that is so, how does hawking radiation work? black holes lose ...

Why isn't Hawking radiation of negative energy? [duplicate]
Hawking radiation is explained by particle-antiparticle creation. A particle with positive energy escapes away from the black hole while the particle with negative energy falls down.
Why isn't that ...

Why would a black hole evaporate? [duplicate]
Hawking radiation doesn't make sense to me, with respect to black holes getting smaller.
It would seem that any particle (or anti-particle) leaving the Schwartzchild radius would have a similar anti-...

Hawking Radiation: Couldn't virtual particles make black holes more massive? [duplicate]
From what I understand about Hawking radiation, a virtual particle comes into existence very near the event horizon of a black hole. This causes one part of the particle to fall into the black hole, ...
