1. Soon afterwards exactly such a particle - the antielectron, or positron - was detected, and we now know that for every type of particle there is an appropriate antiparticle.
2. The particle of matter is instantly whipped towards the black hole by the huge gravitational tug; the antiparticle is simultaneously repelled, and zips off to become a part of our Universe - although probably not for very long, because it will annihilate itself as soon as it encounters another matter particle.
3. That is, the universe would develop in the same way as its mirror image if, in addition, every particle was swapped with its antiparticle!
4. In this case, however, one member of the pair will be a particle and the other an antiparticle (the antiparticles of light and gravity are the same as the particles).
5. Normally they do so in such intimate contact that they immediately annihilate each other, because the force of gravity - and hence of antigravity - is weak over tiny distances when compared with the strong nuclear force and the electromagnetic force, which pull the particle and antiparticle inexorably together.
6. Another way of looking at the process is to regard the member of the pair of particles that falls into the black hole -; the antiparticle, say - as being really a particle that is traveling backward in time Thus, the antiparticle falling into the black hole can be regarded as a particle coming out of the black hole but traveling backward in time.
7. The forsaken particle or antiparticle may fall into the black hole after its partner, but it may also escape to infinity, where it appears to be radiation emitted by the black hole.
8. Two antiparticles could therefore be drawn together by antigravity, but a particle of matter would be repelled by an antiparticle.
9. Just as a particle and an antiparticle will totally annihilate each other if placed in contact, there is no reason why pairs of particles and antiparticles cannot abruptly spring into existence - the accent being on the word "pairs".
10. First, "neutrino" can be used as a general term describing both the particle and its antiparticle counterpart, in a general discussion; secondly, when Wolfgang Pauli coined the name to describe a then hypothetical particle in the 1930s, he used "-neutrino" as the name for the decay product.
11. We now know that every particle has an antiparticle, with which it can annihilate.
12. Because the particle and antiparticle in effect cancel each other out, their appearance together does not violate the laws of physics.
