Albert Einstein spent the latter part of his life pursuing a "single, all encompassing theory of the universe" to describe all of nature's forces. Brian Greene, who is probably best-known for his NOVA specials, is on this path this path of discovery. He says that achieving this may require a whole new way of looking at the world around us.
A professor of mathematics and physics at Columbia University, Greene explains string theory, the concept that minuscule filaments of energy vibrating in 11 dimensions, tucked into the fabric of space, "create every particle and force in the universe." String theory fills in the gaps of Newtonian physics, especially in regards to how gravity works.
Einstein's Unification Theory depends on the existence of extra dimensions, which contain these filaments. Don't miss this peek into the "ultramicroscopic landscape" of our reality — and our upcoming show with string theorist S. James Gates!
