Dark energy may be caused by the pressure of giant voids that seem to tear the universe apart.
An international panel of experts suggests that the giant voids that make up most of the universe may be responsible for the acceleration of the universe’s expansion. These areas are called voids. Space reported it.
It is generally accepted that they occupy up to 80% of the entire space. The rest is occupied by the cosmic web – galaxies are placed in the form of long cosmic filaments, and clusters of galaxies are formed at their intersection. These barren regions are great cosmic voids, the smallest reaching 20 million light-years in diameter, while the largest may be more than 160 million light-years across.
Astronomers suggest that there are voids more than 300 million light-years across. For comparison, our galaxy is only about 100,000 light-years across.
As for dark energy, which astronomers first discovered in the late 1970s, they found that it contributes to the fact that the universe is not only expanding every day, but also accelerating every moment. It is believed that the cosmos began to expand rapidly about five billion years ago.
A new research paper by a group of Iranian theoretical physicists claims that dark energy is not only present in voids, but caused by them.
Scientists believe that these voids will continue to grow and will eventually erase the connections of the cosmic web. This means that the voids in the next few billion years will merge with the help of dark energy, forming larger structures. As a result of this process, the galaxies will separate despite the gravitational attraction between them.
It was previously reported that astronomers, using new data from the Gaia space telescope, have mapped the life of the Sun, and how its history will end.
