The latest study of black holes, the source of dark energy causing the expansion of the universe

Liputan6.com, Jakarta – A new theory finds potential black hole or black holes as the reason behind the expanding universe. This theory was proposed by a research group led by Gregory Tarlé, professor of physics at the University of Michigan.

This theory was published in the Journal of Cosmology and Astroparticle Physics on October 28, 2024. Launching the Live Science page on Monday (04/11/2024), these astronomers have found evidence showing that dark energy, or mysterious energy, driving the acceleration of expansion. universe which may be related to black holes.

Dark energy makes up about 70 percent of the universe. It is believed that this energy appeared after the Big Bang 13.8 billion years ago and fueled the growth of the universe.

However, it is not known where the secret energy comes from. In recent years, several astronomers have put forward a theory that dark energy could emerge from the core of a supermassive black hole instead of spreading throughout space.

Some other astronomers consider this suggestion implausible. Now, a new study claims to have found the first glimpse of a link between the two phenomena, a match between the increasing density of dark energy and the increasing mass of black holes. grow as the universe ages.

By comparing proxy data for dark energy with the growth of black holes at different stages of the life of the universe, the researchers made this idea interesting. These two phenomena are consistent with each other, as new black holes are created during the death of massive stars, the amount of dark energy in the universe is increasing.

Over the years, astronomers have discovered that the universe appears to be expanding at different rates, depending on where they look. This problem is called the Hubble voltage.

Some measurements try to confirm humanity’s current best understanding of the universe, while others try to refute it. Despite the intriguing link between black holes and dark energy, astronomers say more observations, both with the Dark Energy Spectroscopy Instrument (DESI) and other experiments, are needed before definitive conclusions can be made .
