It is widely believed that dark matter exists far more than we have in the universe, so that stars and planets will not be able to form - but scientists at Durham University may claim that it may not be so simple, and the lives of aliens This may be made possible.
But a new study suggests this limit is far more generous than experts once thought, meaning that the conditions needed to sustain existence may not be that rare.
Ever since then, the debate around whether many universes might exist as part of a larger multiverse - and if they could harbour life - has been burning in modern cosmology.
"The Multiverse was previously thought to explain the observed value of dark energy as a lottery - we have a lucky ticket and live in the Universe that forms attractive galaxies which permit life as we know it", saidLuke Barnes of Western Sydney University.
Radio astronomers from around the world have been glued to their sets for decades to listen to that one sound from somewhere in space which would prove that an alien life, sufficiently advanced, exists somewhere in our universe.
The simulations were produced by a team involving scientists at Durham as well as a number of Australian universities.
" We have actually discovered in our simulations that universes with far more dark energy than ours can gladly form stars".
Overall, it's clear that our understanding of dark energy is lacking.

Smith denied feeling frustrated, but the plays sure looked connected. "We can't just expect him to do everything". After a poise-challenged pair of turnovers by the Cavs , Horford nailed a jump shot from 21 feet.
"Even increasing dark energy many hundreds of times might not be enough to make a dead universe".
The findings will be published across two papers in the Monthly Notices of the Royal Astronomical Society. It's more special than it needs to be for life.
The research depicted that if humans would be live in a Multiverse then they should be observing near about fifty times higher dark energy that they are doing at the present.
We would expect to see up to 50 times more in our cosmos based on the multiverse theory, they said.
We can't go beyond our own universe to find the lives of aliens, but this new knowledge of dark energy may adjust the way we look for ways in the future.
"The formation of stars in a universe is a battle between the attraction of gravity, and the repulsion of dark energy", saidRichard Bower of Durham University.
"We found in the simulation that the universe, which is much darker than our energy, can happily form stars". So why such a paltry quantity of dark energy in our universe?
"I think we should be looking for a new law of physics to explain this odd property of our Universe, and the multiverse theory does little to rescue physicists' discomfort".
The multiverse theory suggests that our cosmos is one of a number of different "alternate" universes.
