Physicist Sean Carroll spoke about his vision of a theory that predicts the existence of many parallel versions of reality.
We all perceive the world around us subjectively, but we know one thing from childhood: an object in the world exists regardless of whether we are looking at it or not. However, theoretical physicists and researchers of quantum physics have defended the concept of interpreting reality as a collection of many worlds for years. In essence, they argue that every time a choice is made between event A and event B, reality splits into two parallel branches. In one version, for example, you took an orange from the table, and in another you left it alone. This is how the number of variations of the worlds, which are born every second, is close to infinity.
Physicist Sean Carroll of the California Institute of Technology addresses this problem in his new book, Something Deeply Hidden. In a recent interview with NBC, Carroll clarifies his position on this issue: he considers the hypothesis of "multiple worlds" to be perfectly valid.
According to Carroll, physical reality is largely dependent on the observer, although we are used to thinking otherwise. "Take, for example, an electron or even an atom: they are not in any particular place in space, we can only assume the likelihood of its appearance here or there." Note that both Erwin Schrödinger and Stephen Hawking were seriously engaged in the issues of parallel realities. In his most recent work, Hawking even suggested that it was thanks to quantum mechanics that the Big Bang spawned not one, but an infinite number of universes.
But can you visit them? Alas, as much as science fiction writers want this, Carroll considers it impossible - at least with the current level of technology development. “Parallel worlds do not affect each other in any way, they are completely independent. Finding the point of their intersection is like conquering and surpassing the speed of light, it's incredibly difficult,”he writes.
