There is tremendous agreement that we live in a multiverse. The James Webb Space Telescope has actually given us some very subtle clues about the existence of the multiverse. Indeed, Roger Penrose, a Nobel Laureate, feels very definitely that the James Webb Space Telescope has indeed discovered a multiverse. He believes that the Big Bang actually happened in a parallel universe, before our universe's creation. Also, Max Tegmark and Brian Greene also feel very strongly that we live in a multiverse.
