Our universe is gigantic. While its actual size is not known, the observable universe has a diameter of 28.5 gigaparsecs (93 billion light years). But is our universe the only one, or are there other universes out there? This question has baffled scientists.
The multiverse is a hypothetical set of all universes. This concept has been discussed throughout history and has evolved. Now, the concept focuses on if there is a multiverse, will it have different laws of nature compared to ours? Speaking to Forbes in March, Welsh astrophysicist Geraint F. Lewis said, "Some suggest the burst of inflation in the early stages of our universe might be eternal, with individual universes crystallising out of it, each written with its own unique laws of physics."
There is no direct evidence of a multiverse. So far, the evidence supporting the idea of numerous universes is theoretical.
Experts are divided on two sides when it comes to debating the existence of a multiverse. As per a report by Nat Geo, some experts have argued that it might have been a coincidence that the Big Bang forged a perfectly balanced universe that is just right for our existence. However, others have said it is more likely that any number of physical universes exist, and we simply inhabit the one that is right for our survival.
