Parallel Universes and the Many-Worlds Theory
One model of potential multiple universes called the Many-Worlds Theory might sound so bizarre and unrealistic that it should be in science fiction movies and not in real life. However, there is no experiment that can irrefutably discredit its validity …
For moral reasons, scientists cannot use Moravec’s experiment to disprove or corroborate the existence of parallel worlds, as the test subjects may only be dead in that particular reality and still alive in another parallel universe. In any case, the peculiar Many-World’s Theory and its startling implications challenges everything we know about the world.
