We are all familiar with the Big Bang theory—an event that is widely accepted to have occurred 13.7 billion years ago, which led to the creation of planets, stars and galaxies. In simple words, this theory explains our existence on Earth, which is, in the larger scheme of things, a small speck of dust in the cosmos.
But not all of us know that something extraordinary happened moments after the Big Bang, something our scientists failed to notice. There wasn’t just one explosion, but multiple ones in succession that created an endless number of ‘pocket universes’, just like ours. At least that’s what some of the greatest modern physicists, including professor Stephen Hawking, believe.
In one of his last researches, professor Hawkins said it is possible that we have an infinite number of universes in our cosmos, and reality might not differ much in these parallel worlds. If his research has merit, it’s possible that we all have our doppelgangers, living in a neighbouring universe on a different planet Earth. Someone who is a postman or a football coach on our Earth might be the President of the United States or a National Geographic photographer on the other. There, Hawaii could be a continent, Russia a tiny island; birds might swim in the oceans, while fish fly like kites in the air. Each universe could have its own version of reality that is very, or not very, different from ours.
It is a fascinating thought, indeed, but there is no concrete proof that such a multiverse exists. However, there are various studies that point towards such a possibility. One such paper, published by a string of prominent experts, hails parallel universes as one of the reasons for the origin of Cold Spots—an unusually sized patch in the outer space whose genesis has kept scientists mystified for ages. Co-author of the paper, Professor Tom Shanks of Durham University, said in an interview, “… Cold Spot was caused by a collision between our universe and another bubble universe. If further, more detailed analysis (…) proves this to be the case then the Cold Spot might be taken as the first evidence for the multiverse.” What a day it would be for science when we can finally say for sure that parallel universes exist!
