The lifetime of a particle refers to the amount of time it exists before undergoing a decay or transformation into other particles.
Scientists use particle accelerators and detectors to measure the lifetime of a particle. By observing the decay products and their rates, the lifetime of the original particle can be calculated.
The lifetime of a particle is determined by its fundamental properties and cannot be changed. However, external factors such as temperature and pressure can affect the rate of decay.
Studying particle lifetimes can provide insight into the fundamental laws of physics and the behavior of matter at the subatomic level. It also helps in understanding the formation and evolution of the universe.
No, the lifetime of particles varies greatly. Some particles, such as protons, have a lifetime that is longer than the age of the universe, while others, like muons, have a very short lifetime of only a few microseconds.
