How many dimensions are there?

The world as we know it has three dimensions of space—length, width and depth—and one dimension of time. But there’s the mind-bending possibility that many more dimensions exist out there. According to string theory, one of the leading physics model of the last half century, the universe operates with 10 dimensions.

Can you give more dimensions aside from what is written?

Probability, time are another samples of dimensions. Like the probability of universe. In physics, meters and feet are both units for the dimension of length, whereas seconds and jiffys1 are units for the dimension of time.

Very informative. Thank you.

That is a good refresher. Thank you.
