WASHINGTON — By some estimation , the known universe may contain as many as 2 trillion galaxies , with the average galaxy holding approximately 100 million wizard and untold number of planets . But could there be multiple copies of the entire existence as we understand it ?
The construct ofa multiverse — universe that invisibly coexist alongside us , perhaps representing version of reality that are near - identical to our own — is a pervasive approximation in sci - fi , and one that has intrigue genesis of physicist as well as skill - fable Creator and rooter .
Stop the worlds, I want to get off.
While scientist have yet to witness any evidence that multiverses subsist , there are a number of conjecture that use the laws of physics to research the opening of multiple cosmos , sometimes challenging our understandingof reality itselfin the process , Erin Macdonald , astrophysicist , engineer and self - exalt " monolithic sci - fi nerd , " explicate during a panel on Saturday ( June 17 ) at Future Con , a fete that highlighted the carrefour between science , technology and science fable in Washington , D.C. [ Top 5 Reasons We May Live in a Multiverse ]
Our universe exists within the fabric ofspace - time — 3D space combined with time , to make a 4D continuum , explained Macdonald . But scientists ca n’t say for certain what space - time looks like , which means it might hold unnumerable universe that are unseeable to us , she said .
The simplest edition of the multiverse conception is the so - calledmirror world , in which a single alternate universe tight parallels ours , but is also its opposite — such as the " Mirror , Mirror " episode of the original " Star Trek " telecasting serial , in which a landing place party erroneously beams up to a unlike version of the endeavor , occupied by more cruel versions of their familiar crewmates .
Erin Macdonald at the Future Con panel titled “Parallel and Multi-Universe Theory in Sci-Fi."
Another perspective on the multiverse is thebrane universe , which describes our universe as one membrane in a vast , possibly infinite good deal of membrane universe , but with no connection or means to pass between them , Macdonald said .
Multiple universes might also subsist within contained bubble of space - time , a concept search in the picture game " Bioshock Infinite . " By this numeration , inhabitants of two macrocosm could theoretically interact should their " bubble " connect to each other directly , according to Macdonald .
Quantum universesappear more commonly in sci - fi , Macdonald said . This idea suggest that every decision a person makes spawns a Modern timeline , create a novel and self - contained universe that follow a different way of life . skill - fable writers craftingtime - travel storiesfrequently invoke the rule of quantum universes to explicate how grapheme can move around to the past and not erase their own existence — their every choice deliver new macrocosm whole , go forth the universe that was their stemma entire .
But perhaps the most disturbing premise of all is whether the macrocosm we perceive as real is , in fact , a pretence of some variety , as in the film " The Matrix . "
" Would you want to acknowledge if you were a pretending , but had no restraint ? Could we test if we were in a simulation if we were all just code ? " Macdonald asked the interview . For now , plenty of question remain unanswered — about multiple universes and the reality of our own , she said .
" None of these can be proven — but they ’re fun to think about , " Macdonald said .
