# Exploring the Possibilities Whether Parallel Universes Do Exist

The concept of parallel universes have intrigued scientists for centuries, and has been an integral part of our science fiction. Can there be replicas of our universe? Can there be more than one "us"? Do things work the same way in alternate universes?

Quantum Theory and Many-Worlds Interpretation

Understanding It

He came up with the

*universal wave function*to describe how elementary particles move around. This function describes how elementary particles like an electron, can take up different positions.*Copenhagen interpretation*of quantum mechanics which states that all quantum particles do not exist in one state or other, but rather in all of its possible states at once. This is known as superimposition. The only difference is our observation which allows the object to choose just one state.

What it Implies

What it means is that there are different and equally real set of circumstances in separate universes. It is our choice that splits the universe. So, if you have a near fatal accident in your current universe, in another parallel universe you would probably be dead. The probabilities are endless.

String Theory and "Bubble Universes"

Understanding It

According to this theory, the universe can be explained in form of ten to eleven strings that vibrate in not one, but eleven dimensions. Instead of the point-like particles of particle physics, they are replaced by one-dimensional strings which oscillate in many ways.

What it Implies

According to string theorists, the parallel universes or the soap bubbles, can come into contact with each other. When this happens the gravity can flow between these two bubbles leading to a Big Bang, similar to the one in which our universe was created. They believe that the laws in these universes can be vastly different from the one which we inhabit.

String Theory and "Brane multiverse"

*The Hidden Reality.*

Understanding It

One of the best ways to understand the concept of "braneworlds" is provided by Brian Greene. He says that "

*our universe is one of potentially numerous 'slabs' floating in a higher-dimensional space, much like a slice of bread within a grander cosmic loaf*."What it Implies

These branes are not necessarily parallel to each other, and may at some point slam into each other, thus causing the Big Bang. This cyclic multiverse resets the universe multiple times.
