What is the equation for string theory?
The Hamiltonian of the closed string, provided by the quantum theory, yields a formula for the mass-squared M 2 M^2 M2 of the closed string in terms of these “number operators” [1]: M 2 = 2 α ′ ( N + N ~ − 2 ) .
Are there 11 dimensions?
Scientists do not believe there can exist more than 11 dimensions because conditions become unstable and particles naturally collapse back down into 10 or 11 dimensions. The 12th dimension, for example, introduces a second time. While strings can only vibrate in 10 dimensions, membranes can exist at 11 dimensions.
What is a 100 dimensional shape?
The Googol-cube is a 10100-dimensional hypercube. It’s diameter is (the amount of faces of a Googol-cube) in light years. This cube is a stationary object, stuck in a superposition between existence and non-existence.
Is string theory really a scientific theory?
You’re right: string theory is not a scientific theory. It’s a mathematical theory. That is, it’s a collection of mathematical axioms and related proofs (and an extremely unpleasant one, according to a physicist friend of mine). String theory doesprovide a model of physics.
Why is string theory called a theory?
knowledge about the natural world or a particular phenomenon is gathered,
Is string theory fake physics?
a cosmologist and phd like sean carroll or brian greene it is still fake physics. woit says claims of the multiverse is based on string theory unification, which he regards to be a failed. research program, therefore physicists like sean carroll and several others he mentions are not discussing.
What does the string theory mean in physics?
11 dimensions of spacetime (these extra dimensions should not be confused with the idea in physics of a multiverse of parallel universes)
