Multiverse time line analysis.

This study analyzes modern cosmological topics such as the multiverse, time travel, and extraterrestrial life through logical reasoning and established scientific principles. The discussion concludes that the existence of multiple universes is possible; however, exact duplicate (copy-paste) universes are impossible or extremely unlikely. The popular science-fiction concept of time travel contradicts known physical laws, while time dilation is a real phenomenon. Life may be widespread in the universe, but complex intelligent life is rare, and extinction appears to be a natural universal process.
