In the eternal inflation theory, which is a variant of the cosmic inflation theory, the multiverse or space as a whole is stretching and will continue doing so forever, [68] but some regions of space stop stretching and form distinct bubbles (like gas pockets in a loaf of rising bread). Such bubbles are embryonic level I multiverses.
Time travel can result in multiple universes if a time traveller can change the past. In one interpretation, alternative histories as a result of time travel are not parallel universes: while multiple parallel universes can co-exist simultaneously, only one history or alternative history can exist at any one moment, as alternative history usually involves, in essence, overriding the original ...
Well, in the same sense there may be interlocking universes right here! We have this idea of space, we always think of another universe being someplace else. It may not. Maybe it's right here." In his 'landmark' 1969 book Passport to Magonia: On UFOS, Folklore and Parallel Worlds, Vallee argues for a "parallel universe co-existing with our own ...
Eventually, the vacuum of space will decay, and things will fall apart—in a zillion years. Our universe is glued together by quantum fields, like the Higgs, which set much of our physics.
Black holes are often viewed as inescapable vortexes, but, in a recent talk at Harvard University, Stephen Hawking suggested they might be more like portals than prisons, reports the Boston Globe. ...
The concept of a universe and a multiverse in which the fictional stories take place was loosely established during the Golden Age of Comic Books (1938–1956). With the publication of All-Star Comics #3 in 1940, the first crossover between characters occurred with the creation of the Justice Society of America (JSA), which presented the first superhero team with characters appearing in other ...
Parallel universes [ edit ] The interacting-multiple-universes approach is a variation of the many-worlds interpretation of quantum mechanics that involves time travelers arriving in a different universe than the one from which they came; it has been argued that, since travelers arrive in a different universe's history and not their history ...
This future history and the timeline below assume the continued expansion of the universe. If space in the universe begins to contract, subsequent events in the timeline may not occur because the Big Crunch, the collapse of the universe into a hot, dense state similar to that after the Big Bang, will prevail.
