Antimatter

The video explains that for every particle of ordinary matter, there is a corresponding antiparticle with the same mass but opposite charge. When a particle, like an electron, collides with its antiparticle, a positron, they annihilate each other, releasing pure energy. This process can also occur in reverse.

Explain the concept of mass in relation to particles and antiparticles.

Can the annihilation process take place in reverse? If so, explain how.
