A Higher Dimensional Universe?

Explanation: Does our universe have higher but unusual spatial dimensions ? This idea has been gaining popularity to help explain why vastly separated parts of our universe appear so similar , and why the geometry of our universe does not seem to result naturally from the amounts of matter it seems to contain . The idea is also prevalent in modern attempts to combine gravity and quantum mechanics that include M-theory (formerly string theory ) and Randall-Sundrum theory . Such models involve branes and bulks and frequently attempt to explain, among other things, why some quantum energies and the measured cosmological constant are so small. Above , a dynamic three-dimensional drawing (two spatial plus one time) of a four-dimensional depiction of a five-dimensional cube (a hypercube with four spatial dimensions is also known as a tesseract ) is shown. Donning red-blue glasses will give the best multi-dimensional perspective .
