According to special relativity
1) space and time are aspects of each other. 2) mass and energy are aspects of each other, 3) both of the above, 4) neither of the above, and the underlying postulate of special relativity is 5) F = ma. 6) E = mc2. 7) that the speed of light has a constant value for all observers.
