Abstract

1. Michelson's experiment may be interpreted in another way.
2. When the velocity c = x/t is computed according to Lorentz's formula, it comes out that the contraction of length, equal 1 / (1 - v²/c²)^1/2, and and the dilation of time, equal 1 / (1 - v²/c²)^1/2, cancel each other out.
3. The transformation of time is dependent on the direction of motion. This is to mean that clock time varies with the direction of motion with respect to the source of light.
4. The clock paradox and relative motion.
5. Space is not curved, but light rays are bent by gravity.

The velocity of escape from the universe exceeds, given its size and mass, the velocity of light. Therefore, the universe as a whole behaves like a black hole with all types of galaxies revolving around its center.
