Why do we see only three space dimensions and one time dimension?
There would also be problems with more than three space dimensions.
Therefore, the space dimension is reused, or multiplexed, more than one time.
In 1914, Nordström added a space dimension to his theory.
Even with one space dimension and a constant velocity field, the system remains difficult to simulate.
This is a problem of model reconstruction from sparse data in one time and two space dimensions.
Two space dimensions do not seem to be enough to allow for the development of complicated beings like us.
This result can then be used to obtain the solution in two space dimensions.
Why does the universe appear to have one time and three space dimensions?
Consider the paradox in our 3 space dimensions with one time dimension.
