dark energy, repulsive force that is the dominant component (69.4 percent) of the universe.The remaining portion of the universe consists of ordinary matter and dark matter.Dark energy, in contrast to both forms of matter, is relatively uniform in time and space and is gravitationally repulsive, not attractive, within the volume it occupies.The nature of dark energy is still not well understood.
https://en.wikipedia.org/wiki/Dark_energy
In physical cosmology and astronomy, dark energy is an unknown form of energy that affects the universe on the largest scales. Its primary effect is to drive the accelerating expansion of the universe.Assuming that the lambda-CDM model of cosmology is correct, dark energy is the dominant component of the universe, contributing 68% of the total energy in the present-day observable universe

Some scientists think that dark energy is a fundamental, ever-present background energy in space known as vacuum energy, which could be equal to the cosmological constant, a mathematical term in the equations of Einstein's theory of general relativity. Originally, the constant existed to counterbalance gravity, resulting in a static universe.

About halfway into the universe's history — several billion years ago — dark energy became dominant and the expansion accelerated. While ground-based studies had measured this accelerating period, Hubble's observation of 1997ff stretched back to the decelerating part of the expansion. This shift between two different eras of the

Researchers have measured the expansion history of the universe with the highest precision ever, providing a more detailed look at the nature of dark energy and its effect on the universe. The results are from an analysis of spectra of galaxies and quasars recorded by the Dark Energy Spectroscopic Instrument (DESI).

The dark lines are known as absorption lines and the bright lines emission lines. Each line is due to an energy transition in a particular type of atom or molecule and always occurs at the same wavelength. For example, the hydrogen alpha spectral line occurs at a wavelength of 656.3 nanometres. The hydrogen alpha line occurs when an electron

Dark Energy is the name given to the acceleration of the expansion of the universe. While it is a powerful force on the scale of the entire universe, it should be noted that it is not a very powerful force on scales smaller than the distances between galaxies.
