What does string theory say about multiple dimensions?
String theory smooths out the mathematical inconsistencies that currently exist between quantum mechanics and the theory of relativity. It posits that the entire universe can be explained in terms of really, really small strings that vibrate in 10 or 11 dimensions — meaning dimensions we can’t see.
What is string theory in layman’s terms?
In short, string theory refers to the mathematical models which seek to find a common explanation for the four main forces seen in nature. These forces are the electromagnetic force, the strong and weak nuclear force and gravity.

Why does string theory have 26 dimensions?
However, if these particles happen to be massless, they are permitted and have fewer internal states than massive particles, just like how a photon in four dimensions has two degrees of freedom – its two polarisations. Thus, for them to be massless and preserve Lorentz symmetry, we must require M2=0, so d=26.
Are there 26 dimensions?
There could be an infinite number of dimensions. But as it turns out, at least for SST, 10 dimensions work for fermions and 26 dimensions work for bosons. It was found that the vibrating waves of fermions travel clockwise using 10 dimensions and the vibrating waves of bosons travel counterclockwise in 26 dimensions.
Why does string theory only have 10 dimensions?
Answer Wiki. String theory requires 10 dimensions because it doesn’t work in any other number of dimensions. Roughly speaking, the problem is that the classical string has a certain very important symmetry, and this symmetry is broken when you try to describe a quantum string.
Why is the number 11 important in the string theory?
The number 11 comes from the fact that you can add another dimension to get M-theory in 11 dimensions. This is not really a theory, it’s more a hypothesis that a theory should exist, but no one knows how the String theory requires 10 dimensions because it doesn’t work in any other number of dimensions.
What is string theory and why is it important?
String theory is a theoretical framework that attempts to address these questions and many others. The starting point for string theory is the idea that the point-like particles of particle physics can also be modeled as one-dimensional objects called strings.
Is string theory a consistent theory of gravity?
In coming to understand this calculation, Edward Witten became convinced that string theory was truly a consistent theory of gravity, and he became a high-profile advocate. Following Witten’s lead, between 1984 and 1986, hundreds of physicists started to work in this field, and this is sometimes called the first superstring revolution .
