A new study published in the Royal Astronomical Society has found that if more than one universe does exist, then life could potentially be far more hospitable than earlier thought. Questions about whether other universes might exist as part of a larger multiverse, and if they could harbour life, are burning issues in modern cosmology.
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.
"For many physicists, the unexplained but seemingly special amount of dark energy in our Universe is a frustrating puzzle", said Jaime Salcido from Durham University in Britain.
The research team claims that the stars and planets would still have time to form even if the universe had 100times the dark energy that ours does - increasing the likelihood that alien life could exist outside of our own universe.
The Multiverse theory, introduced in the 1980s, can elucidate the fortunately small quantity of dark energy in our universe because of which life could thrive among many universes that could not.
Using massive computer simulations of the cosmos, the researchers discovered that the addition of dark energy (as much as a few hundred times the amount that is observed in our Universe) would have a significant impact on planet and star formation.
The multiverse theory was first advanced in the 80s.
Although the results do not rule out the Multiverse, it seems the tiny amount of dark energy in our universe would be better explained by an undiscovered law of nature.
The previously proposed theory of dark energy shows that our universe has "perfect" dark energy - a resistance against gravity, which is responsible for making the universe expand at a faster rate. He further said that the multiverse concept shows baby universes getting birth like that of bubbles in a huge multiverse with many fundamental constants and physical laws.
"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", he added.
The Multiverse is a hypothetical group of numerous separate Universes, including the one where humans reside.
The main theory about dark energy is that our universe was created by a short burst, and this explosion made it expand rapidly.
The number of universes could be infinite, meaning there are infinite versions of reality, some of which are very similar to our own.
The European Space Agency says: 'Shine a torch in a completely dark room, and you will see only what the torch illuminates.
Dark matter is thought to be the gravitational "glue" that holds the galaxies together.
