Parallel Universes

Parallel Universes

One idea that comes from the String theory is the idea of “Braneworlds” – parallel universes that are just out of reach of our own. The idea is proposed by Princeton University’s Paul Steinhardt and Neil Turok of the Perimeter Institute for Theoretical Physics in Ontario, Canada. The idea springs from the notion that there are many more dimensions than the three of space and time that we know. Along with this three dimensional “brane” that we inhabit, other three-dimensional “branes” may float in a higher dimension of space. Columbia Univesity physicist Brian Greene describes the idea as the notion that “our space is one of potentially numerous ‘slabs’ floating in a higher-dimension space, much like a slice of bread within a grander cosmic loaf,” in his book “The Hidden Reality” (Vintage Books, 2011). If these parallel universes are indeed true, then movies like THOR might have some possibilities if the “Braneworlds” ever coincide or run into each other.
