A new theory of the fabric of the universe has proposed that time has three dimensions. Moreover, this model leads to the conclusion that these three time dimensions are the true underlying feature of ...

Mathematically, we work with space-time as a four-dimensional continuum: ... (For more on string theory and LQG, see “Imagining our infant universe” in the April 2022 issue.) ...

That is to say, we truly live in a four-dimensional universe. Space and time alone cease to exist; only the union of those dimensions remains. This is what physicists give a single word: spacetime.

So theory crafting as per Einstein imagining what it's like riding on a beam of light. If space-time expands in 5 dimensions, then the light speed barrier becomes emergent. Ie Space expands (in a ...

But we don’t have four dimensions of space; we have three dimensions of space and one dimension of time. And despite what your intuition may have told you, time isn’t “just another dimension.” ...

Their conclusion, which comes from considering the behaviour of qubits, questions the now-dominant idea that four-dimensional space-time is the fundamental fabric of physical reality.

(Phys.org)—The question of why space is three-dimensional (3D) and not some other number of dimensions has puzzled philosophers and scientists since ancient Greece. Space-time overall is four ...
