Hawking Radiation: Can Particles Appear with Relativistic Velocities?

In summary, virtual particles do not have speeds and the Hawking radiation comes from a pair of complementary particles, an electron and a positron for example, coming into existence spontaneously near the event horizon as a result of the intense gravitational field. One particle gets captured by the Black Hole while the other escapes, taking a bit of the BH mass with it. The mass of the two particles is "borrowed" from the BH.

My problem is that in order to escape. that particle must come into existence already moving radially outwards at close to the velocity of light, otherwise it cannot overcome the gravity. Do these particles really pop into existence with relativistic velocities?

Well, your first paragraph is not true: it is a story to help make sense of the mathematics. So asking about the details is kind of pointless.

Is it pointless to suggest that to escape from near the event horizon one has to have a velocity close to c?

I looked at your past posts. You've spent years tossing these random what-ifs at us. In that time, you could have learned GR.

And yes, what you write is pointless. Meaningless, actually. Virtual particles do not have speeds. Further, you missed an important point I wrote: your first paragraph is not true: it is a story to help make sense of the mathematics. Asking us to flesh out the details of something that is not true wastes everybody's time.

Agreed; thread is closed. The OP's profile page says that he has a BS in Physics, so he should be able to do a bit more reading to figure this out. Maybe he'll do that reading and start a new thread with some current journal references if he still is having issues understanding the math behind Hawking radiation. :wink:

1. What is Hawking Radiation?

Hawking Radiation is a theoretical concept proposed by physicist Stephen Hawking in 1974. It suggests that black holes emit radiation due to quantum effects near the event horizon, causing them to slowly lose mass and eventually evaporate.

2. How does Hawking Radiation relate to particles appearing with relativistic velocities?

Hawking Radiation is thought to consist of pairs of particles, one of which falls into the black hole while the other escapes. The escaping particle can reach relativistic velocities due to the extreme gravitational pull near the event horizon.

3. Can particles really appear with relativistic velocities?

According to the theory of Hawking Radiation, yes, particles can appear with relativistic velocities near the event horizon of a black hole. However, this phenomenon has not yet been observed and remains a topic of ongoing research and debate.

4. What is the significance of particles appearing with relativistic velocities in Hawking Radiation?

If this phenomenon is confirmed, it would provide evidence for the existence of Hawking Radiation and support the theory of black hole evaporation. It could also have implications for our understanding of quantum mechanics and the nature of space and time.

5. How is Hawking Radiation being studied and observed?

Hawking Radiation is difficult to observe directly due to its small scale and the extreme conditions near black holes. Scientists use mathematical models and simulations to study its effects and look for indirect evidence of its existence through observations of black holes and their surroundings.
