Alien life could exist in other universes, according to a group of scientists studying a mysterious force known as dark energy.
Previous theories suggested our universe has the perfect amount of dark energy, which acts against gravity and is making the cosmos expand at an accelerated rate.
It was understood that any more would create such rapid expansion that stars and planets wouldn’t have time to form.
The multiverse theory, first put forward in the ’80s, said there was a “luckily small” amount of the force in our universe.
But researchers at Durham University in England claim these celestial bodies would still have formed even if a universe had 100 times the dark energy that ours does.
“The formation of stars in a universe is a battle between the attraction of gravity and the repulsion of dark energy,” said professor Richard Bower of Durham University’s Institute for Computational Cosmology.
“We have found in our simulations that universes with much more dark energy than ours can happily form stars. So why such a paltry amount of dark energy in our universe?
“I think we should be looking for a new law of physics to explain this strange property of our universe and the Multiverse theory does little to rescue physicists’ discomfort.”
Their findings are published in two related papers in the journal Monthly Notices of the Royal Astronomical Society.
