The universe is expanding due to mergers with ‘baby universes’, according to research

Scientists have written different theories about why our universe is constantly expanding, but none of them have been completely confirmed. As explained in a new study published in the Journal of Cosmology and Astroparticle Physics, A team of researchers suggests that the expansion is possible through the merger of ‘baby universes’.

Astronomers know from data collected in experiments with the cosmic microwave background that the universe is expanding at an accelerating rate. In fact, some experts Although there is no possibility yet to confirm the existence of dark matter or dark energy, we note that dark energy is responsible for the expansion.

Researchers of the new study came up with the idea that all of this is the result of fusion through interaction with other universes. Mathematical calculations show that the merger of universes could increase the expansion rate; In fact, scientists argue that the mathematical concept of this theory fits current observations better than the Standard Cosmological Model.

“The main conclusion of our study is that there may be a simple and intuitive explanation for the accelerated expansion of our universe caused by mysterious dark energy, the merger of so-called baby universes, and that a model for this may fit the data better,” said the study’s lead author, physicist Jan Ambjørn from the University of Copenhagen, in a post on the website than the Standard Cosmological Model,” he said in a message. Live Science.

Merger with ‘baby universes’

According to the study’s authors, the mysterious expansion occurred rapidly in the first moments after the Big Bang and may have been influenced by a hypothetical field; This last line of research is covered by the Standard Cosmological Model. According to experts, this super-fast expansion occurred because our young universe was absorbed by a much larger universe.

It was after that The authors explain that our universe continues to collide and merge with ‘baby universes’ after being absorbed by a larger universe. In any case, they plan to continue working on the new proposal to understand whether the expansion is truly affected by this specific process. The James Webb and Euclid space telescopes will help collect more reliable data.

“Our late expansion of the Universe differs from standard cosmological predictions, and we believe that observations from the Euclid Telescope and the James Webb Telescope will determine which model best describes the current expansion of our Universe,” said Tokyo Institute of Technology physicist Yoshiyuki Watabiki. , to the website Live Science.
