You know how it happens? You come to the beach — the water is cold. You are not sure whether you should swim or not. There is a beautiful girl standing next to you. She has doubts about swimming as well. She is looking at you. And you know that if you ask for her name, you will leave with her and forget about everything and everybody — even the person who accompanied you to the beach. All you need to do is ask. But you don’t do it and later keep thinking about her at first once a day, then once a week. For whatever reason, that moment doesn’t leave your head. You can’t stop thinking about the moment when everything could have gone differently, when your life could have taken a whole new direction.
This piercing reasoning of the hero from the movie, Changing Lanes made Bright Side think: Are there really “other lives” in which our destiny could have turned out differently? Spoiler alert: Yes!
Let’s look at this question from the point of view of different sciences.
To prove the theory of alternative realities, we have to go deep into history for a moment: In 1915, two stunning ideas turned the scientific world upside down. One of these being Einstein’s theory of relativity and the birth of quantum mechanics, which radically changed our understanding of the universe. While groundbreaking, these studies didn’t answer all of our questions.
Having realized the gaps in concepts like The Big Bang Theory and the consequences of these theories, the world’s brightest heads have been looking for a universal theory of everything for more than a decade. And finally, from behind the scenes came The String Theory which helped fill the gaps in the inconsistencies of present research.
The String Theory states that everything that exists in this universe consists of the smallest vibrating strings of energy (which are inside the atoms of molecules) with each string oscillating in its own way, generating different particles — similar to notes on a guitar string. To put it simply, the universe is an endless symphony of an orchestra and absolutely everything that surrounds us is music from these tiny strings.
There is another good explanation to this theory using the idea of fire. From the side, a flame seems material, but in fact, it is just energy that cannot be touched (not only because of temperature but in terms of physics). And like a flame, you cannot put your arm into oscillating strings since it is an excited state of space that becomes tangible.
With all the simultaneous simplicity and genius of The String Theory, there was one problem — the solution of which led to the realization of alternative realities.
