How is ~73% of the universe made up of Dark Energy if energy doesn't take up physical space?
Energy is a propery of a system. E.g. potential energy of a body in a gravitational well of another body, or kinetic energy of a body w/r to some reference frame.Bradfordly1 said:How is ~73% of the universe made up of Dark Energy if energy doesn't take up physical space?
Not all bosons are massless. Mesons are bosons and have a mass. But, of course, all bosons are volume less, since they are not subject to Pauli's dxclusion principle.Chronos said:Force carriers, called bosons, are massless and do not occupy space, only massive particles, called fermions, occupy space so there is no limit on the number of bosons that can occupy any given space.
Dark energy is a hypothetical form of energy that is thought to make up about 73% of the universe. It is believed to be responsible for the accelerating expansion of the universe.
Dark energy is not directly observable, but its existence is inferred from observations of the expansion of the universe. The rate of expansion is found to be increasing, which suggests the presence of a repulsive force, which is attributed to dark energy.
Dark energy and dark matter are two different concepts. While dark energy is a hypothetical form of energy, dark matter is a type of matter that is believed to make up about 27% of the universe. Dark matter interacts with gravity, while dark energy is believed to have a repulsive effect on the expansion of the universe.
The Big Bang Theory is the prevailing explanation for the origin and evolution of the universe. It is believed that dark energy was present at the time of the Big Bang and has been expanding alongside the universe ever since. The presence of dark energy is necessary to explain the accelerated expansion of the universe predicted by the Big Bang Theory.
At this time, there is no known way to harness or use dark energy. Its effects are only observed on a cosmic scale and are not currently understood enough to be utilized in any practical way. However, research into dark energy is ongoing, and it may hold potential for future discoveries and advancements in our understanding of the universe.
