Re: How many dimesions are there in the universe/space?

What Bo said struck my thinking.

Hey, dimension could be well defined as degree of freedom!

Then we get many different types of dimension systems, though.

Take: Observer frame D.S.
D1- left-right
D2- front-back
D3- up-down

Take: World space D.S., cartesian style
D1- +ve x axis, -ve x axis
D2- +ve y axis, -ve y axis
D3- +ve z axis, -ve z axis

Take: World space D.S., Polar style
D1- Dist from origin
D2, D3, D4: Angles with axes

Finally if we get some sort of a degree of freedom in time, +ve time, -ve time etc.

How's that for a flash insight?
