How many demensions are there?

Answer 1

In physics and mathematics, the concept of dimensions can vary depending on the context. Traditionally, we experience three spatial dimensions (length, width, height) and one temporal dimension (time), making four dimensions in total in our observable universe. However, theories like string theory propose the existence of additional dimensions—up to 10 or 11—beyond our perceptible reality. These extra dimensions are often compactified and not directly observable.
