Aliens 'exist in the multiverse' like every new superhero film, says expert

Some scientists now propose that alien life could be more likely to exist in parallel universes, or a "multiverse," rather than in our own universe, explaining why no other life forms have made contact with Earth yet. This intriguing idea is laid out in a recent study by a team from Durham University, led by Daniele Sorini, which explores the impact of "dark energy"—a mysterious force thought to drive the universe's expansion. Sorini and his colleagues published their findings in Monthly Notices of the Royal Astronomical Society.

Their research suggests that universes with different dark energy densities could be more conducive to life than ours. Dark energy comprises about 70% of our universe, and the team theorized that life might flourish in universes with an even higher dark energy density. According to their model, a universe with 27% of ordinary matter forming into stars would create ideal conditions for alien life, whereas in our universe, only about 23% of ordinary matter becomes stars.

While traditional searches for alien life have focused on our galaxy, Sorini’s team shifted the perspective by suggesting that the multiverse could be the key to finding extraterrestrial life. Universes with different fundamental constants and optimal conditions might be hiding these unknown life forms, challenging our current understanding of cosmic life possibilities.

However, the researchers clarify that rather than parallel universes as traditionally imagined, these alternate realities might be more like sequential universes existing within a broader multiverse framework. This multiverse theory offers a compelling new angle for the search for alien life, hinting that perhaps life exists just beyond our current reach, in realms of space-time we have yet to understand.
