Number of Dimensions
Date: Winter 2011-2012
I related to my class that there are more than 3 dimensions; to date, how many dimensions are there? What are they?
All we know of are 3 spatial dimensions and 1 time
dimension. Anything greater than that is highly speculative. There
are several variations of theories which require higher numbers of
dimensions are needed. However, as of yet the predictions have
either not been observed, or the theories postulate dimensions that
are far beyond our ability to directly measure.
