Is the following correct about virtual particles

In summary, the answer states that virtual particles are the result of quantum indeterminacy and cannot exist without immediately annihilating. However, at the boundary of a black hole, one particle may become trapped while the other escapes and becomes real, causing the black hole to emit energy in the form of Hawking radiation.

On yahoo I asked if "since virtual particles cone to existence out of nothing. Is it possible that anything else ( discovered or not yet discovered in any universe) would be able to do the same, besides other virtual particles "

And I got this answer

Is it correct?

"No. Virtual particles are simply the result of quantum indeterminancy. It is not possible for empty space to have exactly zero energy, so virtual particles continually pop into existence, only to annihilate again a sliver of a second later. If they didn't annihilate, it would violate the conservation of energy."

True in general, but at a black hole boundary things may be a little different.

In what way may it be a little different

Stated very loosely, a virtual particle pair in the vicinity of a black hole horizon has the potential for one particle to remain trapped, while the other escapes and becomes "real". The black hole thereby radiates energy - hawking radiation.
 

1. What are virtual particles?

Virtual particles are particles that exist for a very short period of time and cannot be directly observed. They are believed to constantly pop in and out of existence in the quantum vacuum.

2. Are virtual particles real?

While virtual particles have measurable effects in quantum mechanics, they are not considered to be physically real in the same way that particles with mass and energy are. They are more accurately described as mathematical constructs used to explain certain phenomena.

3. How do virtual particles work?

Virtual particles are a product of quantum mechanics, specifically the uncertainty principle. They are constantly being created and destroyed, and can interact with other particles, causing observable effects such as scattering and radiation.

4. Can virtual particles be detected?

No, virtual particles cannot be directly detected because they exist for such a short period of time and have no measurable mass or energy. However, their effects can be observed and measured through various experiments in quantum mechanics.

5. Are virtual particles important in everyday life?

No, virtual particles are not important in everyday life because their effects are only observed at the quantum level. However, they play a crucial role in our understanding of the universe and are necessary for explaining certain phenomena in particle physics.
