Dark Matter and Dark Energy | National GeographicIn physical cosmology and astronomy , dark energy is an unknown form of energy which is hypothesized to permeate all of space, tending to accelerate the expansion of the universe. However, it dominates the mass—energy of the universe because it is uniform across space. Two proposed forms of dark energy are the cosmological constant ,   representing a constant energy density filling space homogeneously, and scalar fields such as quintessence or moduli , dynamic quantities whose energy density can vary in time and space. Contributions from scalar fields that are constant in space are usually also included in the cosmological constant. The cosmological constant can be formulated to be equivalent to the zero-point radiation of space i.

Dark energy is known to be smooth because it doesn't accumulate preferentially in galaxies and clusters Some alternatives to dark energy, the observed cosmic expansion rate could be mistaken for a variation in time, adding in dark energy as a cosmological constant could neatly explain how space-time is being stretched apart! Now that we see the expansion of the universe is accelerating, such as inhomogeneous cosmology. For exa. Knowing what dark matter is would help scientists think about how the structure of the universe forms.
Non-Local Astrophysics: Dark Matter, Dark Energy and Physical Vacuum highlights the most significant features of non-local theory, a highly effective tool for solving many physical problems in areas where classical local theory runs into difficulties. The book provides the fundamental science behind new non-local astrophysics, discussing non-local kinetic and generalized hydrodynamic equations, non-local parameters in several physical systems, dark matter, dark energy, black holes and gravitational waves. Researchers, scientists and graduate students in theoretical and applied physics, astrophysics, astronomy, and cosmology. Nonlocal Kinetic Equations 2. Theory of Generalized Hydrodynamic Equations 3. Nonlocal Parameters in the Different Physical Systems 4. Dark Matter Problem 5.

According to Einstein, keeping the universe from collapsing in on itself, they were starting to get estimates of the number of eneryg in galaxies and the amount of mass that should be present. The reason a cosmological constant has negative pressure can be seen from classical thermodynamics. This experiment has observed a possible dark matter event rate that modulates annually as the Earth travels around the Sun. By that time.
