nope, it directly can't because Relativity is bounded by the laws of physics, but it pushs right up to that edge. The boundry between the natrual and unnatrual, light and time.

The problem was Einstein didn't like undefinable factors, as in why he didn't get along well with Quantum Theory which just assumed factors that can't be defined but having set limits. ( how can you have an undefinable factor but it has definable limits?)

Einsteins examination of Minkowski’s Four-Dimensional Space which he assumes the "imaginary" where the rules of 3dimentional space apply to 4th dimentional space, adding in new unknown, but definable factors that lay outside the natural laws of 3Dimentional space but within the laws of 4D space. Our only limitaion then in understanding 4D space is being able to identify the 4D factors.

I think a well known saying fits:

"When you dismiss the impossible, whatever you have left, however improbable, is the answer"

So I think in the end he was trying to do just this. By proving everything else ( of 3D natrual laws), whats left over is the factors in 4D then by scientific study define these improbable factors that define 4D space.
