Sometimes is introduced very interesting theory about the origin of dark energy. The theory claims that the empty bubbles in the universe are the origin of dark energy. The idea is that when photons and all other particles are traveling in the empty bubble they are traveling faster than outside that bubble. And when those particles are smashing to the edge of the empty bubble that particle releases its energy in the form of wave movement. When a particle would fly in an empty bubble where the effect of the quantum fields is lower than other places in the universe there is the possibility that the particle's speed will rise higher than it would be in the regular universe. And when the particle travels outside the empty bubble. It will release its kinetic energy to the universe around it. When that particle hits the "core" of the bubble of nothingness. It releases energy when its speed is slowing. The energy will transmit to the quantum fields of atoms and ions. Th...
