What is the 5th dimension?

Question

We were talking in class about it, and my teacher said she would not tell us now. I have a feeling she forgot.

Answer 1

In physics, the fifth dimension is a hypothetical extra dimension beyond the usual three spatial and one time dimensions. Some scientists have speculated that the graviton, a particle thought to carry the force of gravity, may "leak" into the fifth or higher dimensions which would explain how gravity is significantly weaker than the other three fundamental forces. The Kaluza-Klein theory used a fifth dimension to unify gravity with the electromagnetic force, and now is seen as essentially a gauge theory with gauge group the circle group. M-theory suggests that space-time has eleven dimensions, seven of which are "rolled up" to below the sub-atomic level.

In 1993 the physicist Gerard 't Hooft put forward the holographic principle, which explains that the information about an extra dimension is visible as a curvature in a spacetime with one fewer dimensions. For example, holograms are three dimensional pictures placed on a two dimensional surface, which gives the image a curvature when the observer moves. Similarly, in general relativity, the fourth dimension is manifested in observable three dimensions as the curvature of path of a moving infinitesimal (test) particle. Hooft has speculated that the fifth dimension is really the spacetime fabric.

The Fifth Dimension (also known as The 5th Dimension) is an American popular music vocal group, whose repertoire also includes R&B, soul, and jazz.

The Fifth Dimension were best-known during the late 1960s and 1970s for popularizing the hits "Up, Up and Away" and "Aquarius/Let the Sunshine In."

The five original members were Billy Davis, Jr., Florence LaRue, Marilyn McCoo, Lamonte McLemore, and Ron Townson. They have recorded for several different labels over their long career. Their first work appeared on the Soul City label, which was started by Imperial Records/United Artists Records recording artist Johnny Rivers. The group would later record for Bell/Arista Records ABC Records and Motown Records.

Some of the songwriters popularised by The Fifth Dimension later went on to careers of their own, especially Ashford & Simpson, who wrote "California Soul". The group is also notable for having more success with the songs of Laura Nyro than Nyro did herself, particularly in the cases of "Wedding Bell Blues," "Stoned Soul Picnic," and "Save The Country".

Answer 2

The 5th Dimension was a Motown group in the sixties.

Answer 3

I have a feeling she doesn't know. It was a singing group in the 70's.

Answer 4

how about this?
