# Is string theory mathematically correct?

## Is string theory mathematically correct?

String theory is a quantum theory in that the mass spectrum of strings is discrete, so string theory is an example of a quantum theory of gravity. Furthermore, the dimension of spacetime is uniquely fixed to be ten in order for the theory to be internally consistent mathematically.

**What type of math does string theory use?**

formulation of non-perturbative string theory, which is not yet there, will have to bring together geometry, non-commutative algebra and loop spaces. Over the years string theory [1] has been able to enrich various fields of mathematics.

**Is string theory discredited?**

Experimentation in real life based on string theory is still pretty new, with much to discover. Scientists didn’t find the particles they were seeking, which means one of a few different takeaways.

### What are characteristics of string theory?

The key string theory features include: All objects in our universe are composed of vibrating filaments (strings) and membranes (branes) of energy. String theory attempts to reconcile general relativity (gravity) with quantum physics.

**How many dimensions do we know exist?**

three dimensions

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.

**Are there any fundamental problems with string theory?**

In addition to the problem of developing a consistent theory of quantum gravity, there are many other fundamental problems in the physics of atomic nuclei, black holes, and the early universe. String theory is a theoretical framework that attempts to address these questions and many others.

## Who are the scientists behind string theory and quantum field theory?

Scientists in the Department of Theoretical Physics and at the Mathematical Science Institute are collaborating in understanding the mathematics behind String Theory and Quantum Field Theory.

**How can something be one dimensional in string theory?**

In physics, string theory is a theoretical framework in which the point-like particles of particle physics are replaced by one-dimensional objects called strings. It describes how these strings propagate through space and interact with each other.

**How are models of particle physics based on string theory?**

To construct models of particle physics based on string theory, physicists typically begin by specifying a shape for the extra dimensions of spacetime. Each of these different shapes corresponds to a different possible universe, or “vacuum state”, with a different collection of particles and forces.
