M-theory

Those that attempt to do several at once, such as M-theory.

Since M-theory is thought to operate in 11 dimensions this problem then becomes very difficult.

This fact is important for various relations between M-theory and superstring theory.

This chapter is devoted to speculations on space and time according to M-theory.

The current leading approaches are string theory and M-theory.

Thus each of the five string theories become special cases of M-theory.

What, then, are the underlying degrees of freedom of M-theory?

The proposed M-theory would need one extra dimension and instead be a theory that takes place in 11 dimensions.

Hull is known for his work on string theory, M-theory, and generalized complex structures.

There are different string theories, many of which are unified by M-theory.

In non-technical terms, M-theory presents an idea about the basic substance of the universe.

In M-theory, an extra dimension is added, making seven extra dimensions.

The book examines the history of scientific knowledge about the universe and explains 11 dimension M-theory, a theory many modern physicists support.

In M-theory, which unifies the five types of string theory, there is a seventh dimension involved.

However, the tangible success of M-theory can be questioned, given its current incompleteness and limited predictive power.

M-theory would implement the notion that all of the different string theories are different special cases.

According to Hawking in particular, "M-theory is the only candidate for a complete theory of the universe."

M-theory was also foreshadowed in the work of Paul Townsend at approximately the same time.

Some cosmologists are drawn to M-theory because of its mathematical elegance and relative simplicity.

This maximal supergravity is the classical limit of M-theory.

M-theory (and string theory) has been criticized for lacking predictive power or being untestable.

Excellent references on string theory and M-theory for the layperson and expert.

Matrix string theory formulates M-theory as a random matrix model.
