What exists in the second dimension

Time in several dimensions

It has long been known that the general theory of relativity cannot be reconciled with quantum mechanics. Researchers have therefore been trying for many decades to expand the standard model of elementary particle physics in such a way that all natural forces can be explained. The well-known string theories, for example, postulate that in addition to the three perceptible spatial dimensions, there are further, self-contained or much smaller dimensions.

Itzak Bars and Yueh-Cheng Kuo go one step further in their study and suggest adding a second dimension to time. Your spacetime consists of two dimensions of time and four dimensions of space. The researchers show that these assumptions explain the dynamics of certain interactions between elementary particles better than with previous theories.

According to Bars, the new theory also explains in a simple way symmetries that have long been assumed in the interactions of elementary particles, which until now could only be expressed with complicated hypotheses of the building of supersymmetry. Even the dynamics of the heavenly bodies can be better described by the second time dimension? for example the fact that the elliptical orbits of the planets are stationary in space.

The researchers now want to check further predictions of their theory with the help of computer simulations of the interactions of elementary particles in extended space-time. However, it is not yet clear whether and, if so, when the theory can be verified with experimental tests.
