What is the 5th dimention?

The 5th dimension in Quantum Physics is considered to be different parallel universes similar or very different to our own.

To understand this, you have to consider the 4th dimension as a straight line representing time. The 5th dimension would be a series of lines branching off of that preliminary line - or different outcomes of the current time. It helps to think of it as different "fates" of the universe or different "paths" we can take.

According to this dimensional theory, we are actually 5th dimensional beings: free to move across different 5th-dimentional pathways via chance, luck, choice, and the influence of others.
