0:0.5 Your world, Urantia, is one of many similar inhabited planets which comprise the local universe of Nebadon. This universe, together with similar creations, makes up the superuniverse of Orvonton, from whose capital, Uversa, our commission hails. Orvonton is one of the seven evolutionary superuniverses of time and space which circle the never-beginning, never-ending creation of divine perfection—the central universe of Havona. At the heart of this eternal and central universe is the stationary Isle of Paradise, the geographic center of infinity and the dwelling place of the eternal God.
0:0.6 The seven evolving superuniverses in association with the central and divine universe, we commonly refer to as the grand universe; these are the now organized and inhabited creations. They are all a part of the master universe, which also embraces the uninhabited but mobilizing universes of outer space.

The device is a cylinder a bit smaller than a pinky finger, filled with helium and cooled to just above absolute zero. Inside, a young universe—or something very much like one—evolves. As the helium sloshes about, it mimics a process that may have powered our own universe a few moments after the big bang. And once the fluid settles down, the little whirlpools that remain may be akin to the defects in early spacetime that ultimately gave rise to galaxies, stars and planets.
The study probes the theory of cosmological inflation. This theory posits that just after the big bang, the universe suddenly grew very rapidly for a split second and then, just as suddenly, slowed down. This faster-than-light expansion is supposed to explain all sorts of things about the universe today, such as why it seems to be more or less the same in every direction, and how large objects, such as clusters of galaxies, coalesced out of the cosmos.
The particular type of inflation that the Lancaster group reproduced is called brane inflation, and it is most often associated with string theory, which posits that everything is made of infinitesimal strings. A brane—short for membrane—is an object embedded in some higher-dimensional space, called the bulk. Many things can count as a brane. An infinitely thin string is a 1-brane, because it has only one dimension (its length); a flat sheet is a 2-brane. According to some cosmologists, the universe may be a 3-brane, living in a four-dimensional bulk.
If so, then our universe may not be the only one. There could be many 3-branes, some like the one we live on, floating around in the bulk.
According to the theory, two approaching branes would build up just enough energy to trigger inflation—that sudden, rapid expansion of space. Then, once the branes collide, that energy suddenly vanishes, ending the inflation just as quickly as it started.
... the universe could have smashed into another brane.
DRAGNs are large-scale double radio sources produced by outflows (jets) that are launched by processes in active galactic nuclei (AGN).
The term DRAGN is an acronym for "Double Radio Source Associated with a Galactic Nucleus"
Chunky Universe: Inflation imprinted minuscule defects onto the smooth universe. These defects grew over time, eventually forming the large-scale structure of the universe we observe today. Information from galaxies in a 2-D image [right] can be converted into a 3-D map [left] that shows how galaxies clump together into clusters.
