Multiple cosmos are accessed , in fiction , through portal in space or mystic necklace or sometimes just in dreams , but always when characters break the rules of quad prison term . In reality , substitute universes are not in other dimensions . They ’re just far , far away . And the reason they are substitute universe is that they ca n’t be get through no matter what . But can they be test for ?
A oeuvre to bepublished in the Physical Review Dposits a test , and some interesting conclusions , for multiverse theory . Multiple , or alternating , universes might , less excitingly , be called ‘ very far off places in this universe . ’ The universe is inflate , and has been since the Big Bang . As it expands , sure bubbles of it , also expatiate , are pulled so far off so fast that their light source can never get to this universe again . fundamentally , they are role of the universe that humans from this world can never see , never experience any impression from , and never get hold of . They are , for all hardheaded purposes , dissimilar universes that could be developing in alone different ways .
But they , as well as every other universe include this one , interact with the Cosmic Microwave Background , or CMB . They leave patterns on the cosmic microwave background , which physicists have ferment out would look ‘ disc mold . ’ There is already a greatly detailed survey of the CMB done by the Wilkinson Microwave Anisotropy Probe . Scientists have had a computing machine mark off the CMB for the ‘ key signature ’ of alternate universe , and have found four .
Or have they ? The scientists have found the signatures of substitute universe ‘ bubbles ’ in areas where the multiverse theory is more potential than any other to excuse why the Cosmic Microwave Background looks the way it does in that area , but when looking at the entire creation , four patches of weirdness does not a multiverse make . Even the scientist in charge of the team checking for the multiverse , Dr. Hiranya Peiris , openly states that the current information is n’t enough . Still , it might be fun to intend what ’s out there . World Without Shrimp ? Vogons ?
