AN EXTENDED DISCUSSION ON THE RELATIVITY OF SIMULTANEITY

This article studies the relativity of simultaneity and finds that the relativity of simultaneity will cause "the relativity of existence". It also leads to multiple universes in the real world. Or it will result in "the absence of practical choices" and "the loss of practical possibilities". Also, the relativity of simultaneity will lead to a predestined world and denies the existence of human being free-will choice, the existence of accidental random events, and the existence of probability factors and uncertainty in quantum mechanics.
