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
(formally
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
. News:
A partial solar eclipse will occur tomorrow.
