The secret of dark energy

A study published in the journal Monthly Notices of the Royal Astronomical Society says dark energy is real. This energy makes space - time and the universe expand.

The study was carried out by 26 scientists, including Dr. Chris Blake of the University of Melbourne , Australia, who gave the first independent evidence confirming the existence and expansion of dark energy. . " The study shows that the theory of the famous physicist Albert Einstein is completely accurate. Dark energy is a constant cosmological constant throughout the universe and not a change in the law of gravitation " - Tien Mr. Blake commented.

100 years ago, scientists believed the universe was stable and unchanged. Albert Einstein invented a cosmological constant extending the spatial structure - the time after his own formulas of relativity in general failed to prove that the universe did not move when in a steady state.

Soon, astronomer Edwin Hubble discovered that in fact the universe expanded, like Albert Einstein's original general theory of relativity. Now, before the concept of cosmological constant was proved by visual methods, Einstein abandoned this concept because it showed that he failed to predict the expansion of the universe in theory. Einstein considered it his most stupid mistake.

In 1998, astronomers studied distant exploding stars in the cosmos called Type 1A supernovae, and they found that the universe not only expanded but the cosmic expansion rate was increased by a unknown type of dark energy. Einstein's cosmological constant problem was further studied.

According to Dr. Blake, the acceleration of space expansion is a surprising finding because it shows that scientists need to study more about theories of physics.

To confirm the supernova discovery , Blake and his colleagues spent four years using a state-of-the-art spectrophotometer at the Australian Astronomical Observatory to collect data about 240,000 galaxies returning 7 million times. years ago, when the universe dates to nearly half the current "age" of the universe.

" The observed results show that the structure in the universe increases while the cluster of galaxies and super-massive star clusters grows slowly. This phenomenon shows that the most remote regions in the universe were previously composed of "The ordinary and gravitational forces dominate. However, now the dark energy against gravity has replaced, " Blake said.

Besides, scientists study more about the distance between galaxies.

According to Dr. Blake, the average distance between galaxies is 500 million light-years. Galactic bands tend to grow on compression waves called baryon sound vibrations that spread throughout the universe. These compression waves can be detected as ripples in cosmic microwave background radiation. Dr. Blake also said that the average distance between galaxies has also increased due to space-time expansion. This once again confirms the existence of an anti-gravity agent.

However, Blake acknowledged that the research team has just gathered the above evidence and the exact physical hypotheses needed to explain the phenomenon of darkness are still a mystery. He claimed that asserting dark energy exists is an important step in understanding the origin, evolution and "fate" of the universe.
