Brian Greene's nine types of multiverses include quilted, inflationary, brane, cyclic, landscape, quantum, holographic, simulated, and ultimate. The ideas explore various dimensions of space, physical laws, and mathematical structures to explain …

Aug 23, 2021 · Multiverse theory suggests that our universe, with all its hundreds of billions of galaxies and almost countless stars, spanning tens of billions of light-years, may not be the only one. Instead,...

Jun 25, 2024 · We think our universe contains everything that exists, has ever existed and will exist in the future. But this might not be the case: there are many ways other universes could exist. One is that we...

Jan 16, 2025 · Multiverse, a hypothetical collection of potentially diverse observable universes, each of which would comprise everything that is experimentally accessible by a connected community of observers. The observable known universe would constitute just a small or even infinitesimal subset of the multiverse.

Dec 7, 2012 · In fact, our universe could be just one of an infinite number of universes making up a "multiverse." Though the concept may stretch credulity, there's good physics behind it. And there's not...

Mar 13, 2023 · We break down the different theories about a possible multiverse—including other universes with their own laws of physics—and whether many versions of you could exist out there.

1 day ago · The Multiverse in Popular Culture. The multiverse isn’t just a scientific theory—it’s a playground for storytellers. From comic books to movies, the idea of parallel universes has captured our imaginations. Marvel’s Multiverse Saga explores alternate versions of beloved heroes and villains.

5 days ago · A multiverse of random universes need not have an infinite number of universes. It need only be indefinitely large, i.e., whatever makes our universe likely to appear, no matter how big that number is. The Eternal Inflation multiverse, however, has to be “eternal,” meaning it is effectively infinite and uncaused.

While the universe is the known and observable cosmos that contains galaxies, stars, planets, and living beings, the multiverse theory proposes the existence of an infinite number of parallel universes, each with its own unique characteristics.

In simpler terms, the multiverse challenges the singular notion of our universe by suggesting that there could be other realities, each existing independently. This radical idea has sparked extensive discussions across various scientific fields.
