Quotes About Antiparticle

The antiparticle of any particle has the same mass as the particle, and the same spin. But the antiparticle has the opposite charge.

We now know that every particle has an antiparticle, with which it can annihilate. (In the case of the force-carrying particles, the antiparticles are the same as the particles themselves.) There could be whole antiworlds and antipeople made out of antiparticles. However, if you meet your antiself, don't shake hands! You would both vanish in a great flash of light.

Normally, the energy of the particle is still positive, but the gravitational field inside a black hole is so strong that even a real particle can have negative energy there. It is therefore possible, if a black hole is present, for the virtual particle with negative energy to fall into the black hole and become a real particle or antiparticle.

So, one can regard the pair of particles as a single particle moving on a closed loop in space-time. When the pair is moving forward in time (from the event at which it appears to that at which it annihilates), it is called a particle. But when the particle is traveling back in time (from the event at which the pair annihilates to that at which it appears), it is said to be an antiparticle traveling forward in time.

In fact, the particle-antiparticle annihilation and the closing of the string is necessary, if the theory is to be consistent with relativity, meaning the theory is required to have both open and closed strings. But this means it must include gravity. And the difference between gravity and the other forces is naturally explained, in terms of the difference between open and closed strings. For the first time, gravity plays a central role in the unification of the forces.

There is no such thing as an indescribable material object. Every particle that meets its antiparticle gives up its identity and becomes radiative energy. In the process, the energy is conserved, but the structure of the particle-be it Democritus's sphere or a die, be it charged or neutral-vanishes. It dissolves into pure energy. All identity is absorbed in the sea of pure energy.

Particle-antiparticle pairs fluctuating in the vacuum also permit the fusion of two real photons into a single one, in the presence of an external field.
