How many universes are there? The only meaningful answer to the question of how many universes there are is one,only one universe. And a few philosophers and mystics might argue that even our own universe is an illusion. What's bigger than the Galaxy? From largest to smallest they are: ...
Based on today's best-fit cosmological parameters it is possible to constrain the number of observable Universe sized patches, N_U. Specifically, using the new WMAP data, we can say that there are at least 10 patches out there the same volume as ours. Moreover, even if the precision of...
Other universes Webb's contributions Additional resources Bibliography Galaxies are vast collections of stars that populate our universe. But how many galaxies are there? Counting them seems like an impossible task. Sheer numbers is one problem — once the count gets into the billions, it tak...

While many independent Universes are predicted to be created in an inflating spacetime, inflation never ends everywhere at once, but rather only in distinct, independent areas separated by space that continues to inflate. This is where the scientific motivation for a Multiverse comes from, why no ...
"That's big, but actually more tightly constrained that many other models," according to 2011MIT Technology Reviewreport. Related stories: –Phantom energy and dark gravity: Explaining the dark side of the universe –Do parallel universes exist? We might live in a multiverse ...
the one defined by the CMB. While this fact doesn’t interfere with how we do physics, it reveals that the observable universestartedwith a specific frame. Furthermore, there is no evidence that bits of the universe far away from us are traveling wildly, randomly fast compared to us, sugge...
Some people believe such parallel universesmay also be observablein cosmological data, as imprints caused by another universe colliding with ours. Many-worlds quantum theory gives a new twist on conformal cyclic cosmology, though not one that Penrose agrees with. Our Big Bang might be the rebirth...
recursive language were already apparent. Many famous mind-bending examples from Russel’s barber paradox all the way to Gödel’s Theorem teach us this. Frankly, I think they beat us over the head with a frying pan. But we humans are nothing if not hard headed, and so we g...
In many cases, like in the Bubble Universes or gravastar [92,93,94,95,96,97], which match dS and SW metric, this does not work and the junction requires a surface term (the bubble) to glue both solutions together. For the BHU there are no surface terms [10], which shows that ...
