Is time energy? When the speed of the particle increases the time on it slows. And when the particle reaches the speed of light time stops in it. But slowing the time in particles can be made by simply pumping energy to them. Time dilation means that the existence of particles is extended. Sooner or later all particles in the universe are turning to wave movement. The reason for that is they are losing the energy that keeps them in the form of particles. But is wave movement practice. Yeas and no the wave-particle duality means that the material can turn to wave movement. And wave movement can turn to the material form. But the wave-particle duality is possible only in the world of elementary particles. The wave movement can crepe to particles like quarks and electrons. But protons and neutrons cannot turn back to the particles because they are groups of particles. So existence or lifetime of a particle means the time that protons and neutrons exist in their form. And ...
