Brian Greene introduces us to a new look at the dimensions of common experience by proposing we live in a multidimensional reality.
Based on the studies of Einstein, gravity is nothing but warps and ripples in the 4 familiar dimensions of space and time. Physicist, Theodor Kaluza takes it one step further proposing that electromagnetism might also be ripples, thus concluding that an additional hidden dimension of space would need to exist.
These theories surrounding spatial dimensions give rise to a greater understanding of 'String Theory' and its place in our reality.
