The concept of a multiverse encompasses the idea that there are multiple universes with different physical properties, laws of physics, or fundamental constants. It does not necessarily imply that every conceivable situation or hypothesis exists as a separate universe within the multiverse.
The existence of a multiverse is a speculative hypothesis proposed to explain certain phenomena or to address theoretical questions in physics. It is based on extrapolations from current theories and mathematical frameworks. However, the validity and scope of the multiverse concept are still subjects of ongoing research and investigation.
It's worth noting that the idea of a multiverse is not universally accepted among physicists, and various interpretations and versions of the multiverse hypothesis exist. Some physicists and philosophers argue that the multiverse hypothesis may not be testable or verifiable, and therefore it may fall outside the realm of scientific inquiry.
In summary, the concept of a multiverse is not explicitly required to encompass every possible situation or hypothesis, and its validity and scope are still subjects of active scientific debate.
