The True Science of Parallel Universes
minutephysics・2 minutes read
Physicists distinguish between the "observable universe" and the entire universe, with the concept of the Multiverse encompassing various models like Bubble universes, Membranes, extra dimensions, and the many-worlds theory, each offering unique explanations for the universe's existence and structure. While the Bubble universes model suggests hidden parts of the universe, the many-worlds hypothesis posits that all potential outcomes are real, although experimental evidence for this idea is currently lacking.
