We used to think of the universe as all that exists around us, but scientists are here to show us there’s more than that. They’ve started for some time to study the idea that there might be more than one universe. All of the unknown and possible universes are known as the multiverse.
Scientists in the U.K. and Australia have a new question:
Could the multiverse host life?
Using computer simulations, researchers have found out that, if a multiverse exists, it could host life. You can find the papers in the journal Monthly Notices of the Royal Astronomical Society, which were published on 14 May.
This research is based on the idea of the multiverse which astrophysicists calculated by taking into consideration dark matter. Dark matter continues to accelerate the expansion of our universe. Astronomers used the multiverse theory in the 1980s to explain the small amount of dark energy from our universe. It seems that a small amount of dark energy has enabled life in our universe. If dark energy enables a universe to host life, then the same could happen in the multiverse.
We Got the Lucky Lottery Ticket
Lead author on one of the papers published today explains that our universe just happens to have “… a lucky [lottery] ticket.” That’s because if our universe had more dark matter, it would have expanded faster and matter would have been diluted before stars, planets, and life could have time to form.
Jaime Salcido is a postgraduate student in Durham University’s Institute for Computational Cosmology and the lead author on one of the recently published papers. He said:
“For many physicists, the unexplained but seemingly special amount of dark energy in our universe is a frustrating puzzle.”
Trying to add in the simulations more or less dark energy, Salcido and his colleagues found this:
“Our simulations show that even if there was much more dark energy or even very little in the universe then it would only have a minimal effect on star and planet formation, raising the prospect that life could exist throughout the multiverse.”
