Everything about Multiple Time Dimensions totally explained
The possibility that there might be
more than one dimension of time has occasionally been discussed in
physics and
philosophy.
Physics
Special relativity describes
spacetime as a
manifold whose
metric tensor has a negative
eigenvalue. This corresponds to the existence of a "time-like" direction. A metric with multiple negative eigenvalues would correspondingly imply
several timelike directions, for example multiple time dimensions, but there's no consensus regarding the relationship of these extra "times" to
time as conventionally understood.
Nonetheless, theories with more than one dimension of time have sometimes been advanced in physics, whether as a serious description of reality or just as a curious possibility. Itzhak Bars's work on "two-time physics"
(External Link
), inspired by the SO(10,2) symmetry of the extended supersymmetry structure of
M-theory, is the most recent and systematic development of the concept (see also
F-theory).
Philosophy
An Experiment with Time by
J.W. Dunne (1927) describes
(External Link) an
ontology in which there's an infinite hierarchy of conscious minds, each with its own dimension of time and able to view events in lower time dimensions
from outside. His theory was often criticised as exhibiting an unnecessary
infinite regress.
The conceptual possibility of multiple time dimensions has also been raised in modern
analytic philosophy.

In fiction
The Number of the Beast by
Robert A. Heinlein (1980) features a six-dimensional
cosmology in which there are three time dimensions, denoted
t,
tau (
Greek τ) and
teh (
Cyrillic cursive
т).

The
Ware Tetralogy by
Rudy Rucker features
aliens called Metamartians who "are from a part of the cosmos where time
is two-dimensional".
