More Than Meets the Eye

Scientist have long speculated that our universe has more dimensions than we now realize ... some offer as many as 24. Imagining an universe beyond four dimensions (length, width, depth and time) gets a little dicey. This has to do with our senses. Unless we can sense things with our eyes, we have difficulty imagining them as dimensions of our world (time being somewhat of an exception).

But what about our other senses? If gravity (or related "force") is a dimension, we actually can sense it without the use of our eyes. Same thing with temperature. What about color (yes, eyes are involved but,more broadly, the entire electromagnetic spectrum ... maybe adding brightness and saturation to the mix)? What about sound? What about magnetism? In this case other animals are said to have such sensors. My guess is when it is decided what any additional dimensions beyond four are finally agreed upon, they will not be tiny strings curled up (as string theory postulates) but much more pedestrian things like suggested above.

There is more to life (and science) than meets the eye ...

Afterward: Add speed (of light) to the above list. Didm't Einstein tell us that speed was absolute and not relative to its platform?
