Particle-antiparticle pairs

Particle-antiparticle pairs are pairs of fundamental particles that have opposite properties, such as electric charge. They are created together from energy, often in high-energy environments like the early universe or particle collisions. When they meet, they can annihilate each other, converting back into energy. This process exemplifies Einsteins's equation, E=mc², showing how energy and matter are interchangeable. These pairs are essential in understanding the behavior of matter and energy at a fundamental level and play a key role in particle physics and cosmology.
