Albert Einstein believed space and time made up a fourth dimension. An example from a string theorist gives a view of what a fourth dimension could be. We move through three dimensions.
Firstly, four-dimensional accounts of time are argued to better explain paradoxes of change over time (often referred to as the paradox of the Ship of Theseus) than three-dimensional theories. A contemporary account of this paradox is introduced in Ney (2014), [ 3 ] but the original problem has its roots in Greek antiquity.
Four-dimensional space (4D) is the mathematical extension of the concept of three-dimensional space (3D). Three-dimensional space is the simplest possible abstraction of the observation that one needs only three numbers, called dimensions, to describe the sizes or locations of objects in the everyday world.
1922: The Big Bang theory of the universe—that the universe is expanding from a single original point—was developed from the independent derivation of the Friedmann equations from Albert Einstein's equations of general relativity by the Russian, Alexander Friedmann, in 1922, and by the Belgian, Georges Lemaître, in 1927.

The theory of special relativity was initially developed in 1905 by Albert Einstein. However, other interpretations of special relativity have been developed, some on the basis of different foundational axioms. While some are mathematically equivalent to Einstein's theory, others aim to revise or extend it.

The higher-dimensional generalization of the Kerr metric was discovered by Robert Myers and Malcolm Perry. [1] Like the Kerr metric, the Myers–Perry metric has spherical horizon topology. The construction involves making a Kerr–Schild ansatz ; by a similar method, the solution has been generalized to include a cosmological constant .
According to the special theory of relativity introduced by Albert Einstein, it is impossible to say in an absolute sense that two distinct events occur at the same time if those events are separated in space. If one reference frame assigns precisely the same time to two events that are at different points in space, a reference frame that is ...
