What is Dark Energy?

Dark energy is the energy that drives the movement of the universe. Neither it nor dark matter absorbs, reflects, or radiates light, so humans cannot directly use existing technologies for observation.

Dark energy

The origin of the concept of dark energy has to be traced back to the master of science

The Japan Physical and Chemical Research Institute issued a press release saying that a research team led by Nao Hisao and the Suriname University of Stanford University of Japan has observed about 23,000 quasars in space to find the "gravity lens effect" Affected quasars.

The so-called "

If these alternative dark energy theories can hold, they will point to a very different future for the universe:

What is dark energy and what does its existence mean? Scientists are just beginning to try to answer these

By observing and analyzing the X-rays emitted by distant galaxy clusters, European Space Agency scientists have obtained results that are inconsistent with dark energy theory. However, experts point out that whether the new results mean that the cosmic dark energy that people have been discussing "may not exist" needs more observational research to prove.

According to foreign media reports, according to a recent study, the universe may not be accelerating. This means that the mysterious "dark energy" may not actually exist. This is a quite shocking claim. You know, in 2011, the Nobel Prize in Physics was awarded to three astronomers from two research teams, because they independently proved that the distant type Ia supernova (an exploding star) is better than celestial bodies near Earth Faster away from the earth. In other words, our universe is accelerating. These surprising results, published in the late 1990s, strongly suggest that there are some strange forces separating time and space.

The reason is that without these forces, the expansion of the universe from the Big Bang 13.8 billion years ago could not continue to accelerate. Instead, it will gradually slow down due to the gravitational effects of all galaxies, black holes, and other matter in the universe. Since astronomers did not know the exact nature of this force at the time (and in fact do so now), the force in this hypothesis was called dark energy . But a report published Friday (October 21) in the journal Science Report questioned this Nobel-level conclusion. The first author of the article was JT Nielsen of the Niels Boll School of the University of Copenhagen. Together with his colleagues, he analyzed more than 740 Type Ia supernovae using a different theoretical framework than the Nobel Prize team of the 1990s.

According to the temperature spectrum of WMAP generated by Li Tizhen, an academician of the Chinese Academy of Sciences, and Liu Hao, a doctoral student, the proportion of dark energy and dark matter in the total energy of the universe has changed. Dark energy has dropped from 74% to 68% as announced by the WMAP team, while dark matter has risen from 22% to 28%. They claimed in the paper that this result is in better agreement with the results of the WMAP group than other observations, such as "darts" ball-borne telescopes, baryon oscillations, type Ia supernovae, etc.
