Superstring theory posits that the universe exists in 10 dimensions at once. ... These different aspects are what govern the universe, the fundamental forces of nature, and all the elementary particles contained within. The first dimension, as already noted, is that which gives it length (aka. the x-axis).
Why does string theory need 10 dimensions?
In our personal human experiences, we seem to exist in a universe with three spatial dimensions. Some theories in physics, including string theory, include the idea that there are additional spatial dimensions. Such theories suggest that there may be a specific number of spatial dimensions such as 10.
Why does string theory need 11 dimensions?
In string theory, the multiverse is made of different dimensions but the highest is 11th dimension. Beyond 11 dimensions, the universe would become unstable and dimensions higher than 11 would collapse to an 11-dimensional universe.
