Virtual particles are particles which flash into and out of existence spontaneously. ... Virtual particles are particles which flash into and out of existence spontaneously. They are allowed to "borrow" rest energy via the uncertainty principle...

The virtual particle then completes the decay process. In some cases, the intermediate virtual particle has more mass than the initial particle or the final set of decay products; ... Heisenberg's uncertainty principle, which explains the virtual particle phenomenon, is most commonly stated as follows: It is impossible...

Any isolated real particle satisfies the generalized Einstein relativistic relationship between its energy, E, its momentum. p, and its mass, m (c is the speed of light): ... Virtual particles are a language invented by physicists in order to talk about processes in terms of the Feynman diagrams. These diagrams are a...

The lifespan of a virtual particle is on the order of 10-43 second and decreases as the non- existant energy used to create the particle and its antiparticle increases. Virtual particles, unlike their real counterparts, are undectable and do not interfere with the physical world.

And what if one virtual particle falls into a black hole? ... If one virtual particle falls into the black hole and the other one escapes, it escapes as Hawking radiation from the black hole. This radiation shows the same allocation as black body radiation. This assumes that black holes do have a temperature too.

The Virtual Energetic Particle Observatory (VEPO) serves the heliophysics data user community as a focus group component operating within the domain of the Virtual Heliospheric Observatory (VHO) for improved discovery, access, understandability, and usability of energetic particle data products from selected spacecraft...

Now, when I first read this my reaction sounded a lot like this, "Well what the heck does that mean!" What does Hawking mean when he says the particle is virtual, that it can't be detected directly but it does have measureable effects.

(Created prior to 1993) Question: In the book/movie "A Brief History of Time," Steven Hawking mentions that black holes can be detected by looking at virtual particle creation and annihilation events near a black hole event horizon.
