NASA Says 2 Asteroids Will Safely Fly By Earth This WeekendScientists Discover Possible Interstellar Visitor Stay on target Stephen Hawking got the ball rolling in his final theory on the origin of the universe, which provides evidence for the presence of a “multiverse.”Which, if he’s right and it does exist outside of Marvel Comics, means there may be extraterrestrial life out there after all.New research from the UK and Australia shows that other universes may not be as inhospitable to life as we previously thought. The key, researchers said, is dark energy—a mysterious “force” accelerating the expansion of the cosmos.By adding more of it (up to a few hundred times the amount observed in our universe), the international team of cosmologists were able to simulate its “modest impact” on star and planet formation.These reproductions were produced under the EAGLE (Evolution and Assembly of GaLaxies and their Environments) project.“For many physicists, the unexplained but seemingly special amount of dark energy in our universe is a frustrating puzzle,” Jaime Salcido, a postgraduate student in Durham University‘s Institute for Computational Cosmology, said in a statement.“Our simulations show that even if there was much more dark energy or even very little in the universe,” he continued, “then it would only have a minimal effect on star and planet formation, raising the prospect that life could exist throughout the multiverse.”Introduced in the mid- to late-1980s, the idea of a multiverse explains the “luckily small” amount of dark energy in that enabled life.As the story goes, our universe began with the Big Band. During a period of rapid expansion (known as inflation), the cosmos swelled from subatomic to gold ball-sized almost instantaneously—possibly creating various pocket worlds, i.e., the multiverse.Which, according to Hawking, may not be so different from our own.“The multiverse was previously thought to explain the observed value of dark energy as a lottery,” Luke Barnes, a Templeton Research Fellow at Western Sydney University. “We have a lucky enough ticket and live in the universe that forms beautiful galaxies which permit life as we know it.“Our work shows that our ticket seems a little too lucky, so to speak,” he continued. “It’s more special than it needs to be. This is a problem for the multiverse; a puzzle remains.”This sounds like a job for Supergirl and The Flash!The findings are published in two papers—one led by Durham University, the other by the University of Sydney—in the journal Monthly Notices of the Royal Astronomical Society.
