"Well, reliable evidence is yet to come to our notice, but, according to an international team of scientists, they could be living in a parallel universe," says an article posted on livescience.com.
The team comprising researchers from England, Australia and the Netherlands came to this conclusion after running a programme called 'Evolution and Assembly of Galaxies and their Environments'.
The team has published its results in the journal Monthly Notices of the Royal Astronomical Society.
In their research, dark energy (opposite of gravity) appeared as a crucial factor.
They found out that even if dark energy is hundred times the amount in our own universe, galaxies can still be formed, making up a parallel Universe and then becoming home to a life.
