I was watching Stephen Hawking's documentary and in there he explained how he realized why black holes eventually disintegrate:
There are ripples in space, an antiparticle and a particle get created for a brief time then annihilate each other. When this happens very close to a black hole sometimes an antiparticle will be sucked in, but normal particle will escape. Hence the black hole radiation is due to extra particles escaping and black hole disintegration is due to antimatter getting sucked in.
That made me think what happens around ordinary matter. If the antiparticle is close enough to a normal particle then it will annihilated. So is this what is responsible for Radioactive Decay? And how does it affect normal matter? For example a human being? Does it mean that all the atoms will eventually disintegrate?
I am not QM savy so if you can explain it in layman terms that would be very appreciated.
