Five weird theories of what lies outside the universe

Physicists have long studied the nature of the universe of discourse . But some go a whole step further into the unknown ( and likely unknowable ) , reflect what lie down outside the boundaries of our universe .

Is it possible that something else exist beyond existence ? Yes . Here are five theory about what that “ something ” might be .

The “ outside the universe ” question gets sly right off the bat , because first you have to define the universe . One common answer is called the observable universe , and it ’s defined by the amphetamine of light . Since we can only see things when the light they utter or reflect reaches us , we can never see farther than the farthest distance light can travel in the time the existence has exist . That mean the observable universe keeps arrive large , but it is finite – the amount is sometimes referred to as the Hubble Volume , after the scope that has given us our most distant views of the macrocosm . We ’ll never be able-bodied to see beyond that boundary , so for all intents and purposes , it ’s the only universe we ’ll ever interact with .

Beyond the Hubble Volume . We know with some foregone conclusion that there ’s “ more universe ” out there beyond that boundary , though . Astronomers think blank space might be infinite , with “ material ” ( energy , galaxies , etc . ) distributed pretty much the same as it is in the evident cosmos . If it is , that has some severely unearthly implications for what lies out there . Beyond the Hubble Volume you wo n’t just find more , unlike satellite . You will eventually find every possible thing . show that again and lease it slump in . Everything . If you go far enough , you ’ll find another solar system with an Earth indistinguishable in every way except that you had cereal for breakfast this morning instead of eggs . And another where you skipped breakfast . And one where you have up early and rob a money box . In fact , cosmologists think that if you go far enough , you will find out another Hubble Volume that is perfectly indistinguishable to ours . There ’s another version of you out there mirror your every activeness 10 to the 10 ^ 188 meters away . That may seem unlikely , but then , eternity is rottenly infinite .

Dark Flow . In 2008 , uranologist discovered something very strange and unexpected – galactic clusters were all pelt in the same focal point at immense speed , over two million sea mile per hour . newfangled observations in 2010 confirmed this phenomenon , known as Dark Flow . The movement defies all predictions about the distribution of mass throughout the universe after the Big Bang . One possible grounds : monumental structure outside the Hubble Volume exerting gravitational influence . This would mean that the structure of the innumerable universe beyond our view is not consistent . As for the structures themselves , they could be literally anything , from aggregations of thing and energy on scales we can barely imagine to bizarre warps funnel gravitative forces from other macrocosm .

Infinite Bubbles . Talking about things outside the Hubble Volume might be a turn of a cheat , since it ’s still really the same existence , just a part of it we ca n’t see . It would have all the same physical laws and constants . In another version of the story , the post - Big Bang expansion of the macrocosm caused “ bubbles ” to form in the structure of space . Each house of cards is an area that stopped stretching along with the relaxation of place and formed its own universe , with its own laws . In this scenario , infinite is infinite , and each bubble is also infinite ( because you’re able to store an myriad number of infinity inside a exclusive infinity ) . Even if you could somehow breach the boundary of our house of cards , the space in between the bubbles is still blow up , so you ’d never get to the next house of cards no matter how fast you went .

Black Hole Spawning . A theory proposed by physicist Lee Smolin , known as the fecund universes possibility , suggests that every pitch-black trap in our universe make the organisation of a new universe . Each universe will have somewhat unlike physical laws than the forerunner universe . In this manner , Smolin suggests a form of innate selection for universes , as law that leave to the frequent formation of dim holes lead to the creation of more universe of discourse , while non - bleak hole forming creation “ die out . ” This theory has since been discounted ( by Smolin himself and others ) .

Many Parallel Universes . There are tons of theories about parallel macrocosm , but the most accepted one these days involves an evolution of the approximation of string theory to involve membranes that vibrate in other dimensions . It ’s beyond the reach of this article to get too elaborate about string or tissue layer hypothesis , but the consequence of the whole affair is that these rippling tissue layer in the 11th dimension are whole other universe , and when the ripples flap down into each other they form a new universe . The consequence of the guggle movement avail excuse the observed dispersion of matter in our population . One of the unearthly elements of the hypothesis is the musical theme that all the solemnity we experience in our cosmos is actually leaking into it from another universe in another proportion ( which explicate why gravitational attraction here seems so watery compared to the other fundamental forces ) .
