One of the reasons why humanity has not found evidence of aliens so far may be that they exist in a parallel Universe. This assumption was presented in a paper published in Monthly Notices of the Royal Astronomical Society. A team of astrophysicists led by Daniele Sorini of Durham University has proposed a new approach to analyzing the Drake equation and explaining the Fermi paradox.
The famous equation created by Frank Drake in the 1960s allows us to estimate the number of advanced civilizations in our galaxy. It takes into account the rate of star formation, the number of habitable planets, and the probability of intelligent life. However, Sorini and his colleagues adapted this equation to the conditions of the Multiverse, a hypothetical concept that assumes the existence of other Universes with different parameters.
Role of dark energy
The main focus of researchers is on dark energy, the mysterious force that accelerates the expansion of the Universe. The team found that in parallel Universes with more optimal dark energy densities, life could evolve much more easily. For example, worlds where 27% of ordinary matter turns into stars have a higher probability of life than ours, where the figure is 23%.
“We were surprised to find that even at much higher densities of dark energy, life could exist. This hints that our Universe may not be the most favorable for the development of life,” Sorini noted.
The Multiverse Hypothesis
The idea that aliens “hide” in other Universes may sound too fantastical. But it allows us to link the exotic hypotheses of modern physics to the search for extraterrestrial life. Scientists believe that studying dark energy and its influence on the evolution of the Universes could help find answers to questions about our own existence.
“This study opens up the possibility of rethinking fundamental questions about the Universe. For example, how different parameters governing universes affect the emergence of life,” added Lucas Lombriser, a professor of cosmology at the University of Geneva and co-author of the paper.
Thus, the Multiverse not only expands our understanding of the cosmos, but also helps explain why we have not made contact with alien civilizations to date.
We previously reported on how the public’s growing belief in the existence of extraterrestrials could prove dangerous.
