The so-called dark energy, according to the current popular saying, dark energy refers to a kind of energy with negative pressure that fills space. According to the theory of relativity, this negative pressure is similar to a kind of anti-gravity at long distances. This conjecture is one of the most popular solutions to explain the accelerated expansion of the universe and the lost matter in the universe.
In physical cosmology, dark energy is an imperceptible form of energy that fills space and increases the expansion speed of the universe. The dark energy hypothesis is one of the most popular interpretations of the observations of the accelerated expansion of the universe. In the standard model of the universe, dark energy occupies less than 70% of the mass and energy of the universe.
Astronomer Edwin Hubble discovered that other galaxies in the universe seem to be moving further and further away from the Milky Way where people live, and the farther they move, the faster they move. However, astrophysicists have previously pointed out that gravity will gradually slow down the expansion of the universe. Then in 1998, the two research teams overturned the theory put forward by astrophysicists by observing Type Ia supernovae — a rare phenomenon in which stars explode and emit a huge amount of long-lasting light.
By carefully measuring how the light from these activities changes toward the red end of the visible spectrum — similar to the "Doppler effect" in which the tone of the train whistle becomes lower and lower when the train gets farther and farther away from you. "Vacuum" (some scientists believe that "vacuum" is not empty) space itself seems to be acting as a force that can separate matter. ( Ref. to see Baidu Encyclopedia )

Comment: The kind of dark energy that scientists are currently studying is likely to be the mixture of life wisdom wave energy and gravitational wave energy we are talking about, because these two waves are usually mixed together. The gravitational wave is biased towards celestial bodies, and the life wisdom wave is biased towards animals and plants. Part of the energy of electromagnetic waves is light, which is bright energy. Scientists usually mess up this part of the concept.

The so-called dark matter refers to matter that cannot be studied through the observation of electromagnetic waves, that is, matter that does not interact with electromagnetic force. At present, people can only know through the effect of gravity, and it has been discovered that there is a large amount of dark matter in the universe.
Modern astronomy detects dark matter through methods and theories such as gravitational lensing, the formation of large-scale structures in the universe, and microwave background radiation. According to the ΛCDM model, obtained from the data detected by the Planck satellite: In the composition of the entire universe, the matter we often say accounts for 4.9%, while dark matter accounts for 26.8%, and 68.3% is dark energy ( Mass-energy equivalent ). The existence of dark matter can solve the inconsistency in the big bang theory and is also critical to the formation of structures. Dark matter is likely to be composed of one ( or several ) new particles outside the standard model of particle physics. The study of dark matter ( and dark energy ) is an important subject of modern cosmology and particle physics. ( Ref. to see Wikipedia )

Comment: The dark matter currently studied by scientists may be the life wisdom body we are talking about. It is in the form of mass-energy conversion with the life wisdom waves, gravitational waves or electromagnetic waves.
