Question

Are there other universes?​

Answer 1

Our universe is a very unlikely place. Alter some of its settings even slightly and life as we know it becomes impossible. In an attempt to unravel this “fine-tuning” problem, physicists are increasingly turning to the notion of other universes. If there is an infinite number of them in a “multiverse” then every combination of settings would be played out somewhere and, of course, you find yourself in the universe where you are able to exist. It may sound crazy, but evidence from cosmology and quantum physics is pointing in that direction.
