"Long before it's in the papers"August 04, 2011RETURN TO THE WORLD SCIENCE HOME PAGE--------------------------------------------------------------------------------Scientists testing theory that there are multiple universesAug. 4, 2011Courtesy of University College Londonand World Science staffA group of phys­i­cists claims to be con­duct­ing the first test of a the­o­ry that holds our uni­verse is just one of many.Their re­sults? Poss­ible evi­dence in sup­port of the the­ory has been found, but more da­ta re­mains to be ex­am­ined, they re­port.They’re look­ing for disk-like pat­terns in the cos­mic mi­cro­wave back­ground radia­t­ion—a type of heat radia­t­ion that per­me­ates the skies and is be­lieved to be left over from the Big Bang, an ex­plo­sive event that gave birth to our uni­verse. These pat­terns could pro­vide tell-tale ev­i­dence of col­li­sions be­tween oth­er uni­verses and our own, the re­search­ers ex­plain.The re­search is de­scribed in pa­pers pub­lished in the jour­nals Phys­i­cal Re­view Let­ters and Phys­i­cal Re­view D.An in­i­tial pro­pos­al de­scrib­ing the idea be­hind such tests was pub­lished in the lat­ter jour­nal in 2007. Many mod­ern the­o­ries of fun­da­men­tal phys­ics pre­dict that our uni­verse is in a bub­ble, and that there are oth­er bub­bles con­tain­ing oth­er uni­verses, per­haps with dif­fer­ent laws of na­ture. The search for disk-like pat­terns is based on the no­tion that uni­verses might knock to­geth­er. These bumps could then leave round “bruis­es” on the sur­face of each col­lid­ing uni­verse, like two pears that have been smacked to­geth­er. These marks would al­so be re­flected in the mi­cro­wave back­ground—specifically, in the maps that astron­om­ers have put to­geth­er show­ing temp­er­ature vari­a­tions in this ra­dia­tion at diff­erent points ac­ross the sky.One prob­lem was that be­fore now, it was hard to search for the disk-like pat­terns be­cause they could be any­where in the sky—and have any size. Phys­i­cists al­so needed to be able to test wheth­er any pat­terns they de­tected were really the re­sult of col­li­sions or just flukes in the da­ta. “It’s a very hard sta­tis­ti­cal and com­puta­t­ional prob­lem,” said Hiran­ya Peiris of Uni­vers­ity Col­lege Lon­don, co-author of the re­search. “But that’s what pricked my cu­ri­os­ity.”Peiris and col­leagues from Im­pe­ri­al Col­lege Lon­don and the Pe­rim­e­ter In­sti­tute for The­o­ret­i­cal Phys­ics in Wa­ter­loo, On­tar­i­o, ran sim­ula­t­ions of what the sky would look like with and with­out col­li­sions. The find­ings al­so pro­vided an up­per lim­it on how many such bub­ble col­li­sion signa­tures there could be, the sci­en­tists said.“The work rep­re­sents an op­por­tun­ity to test a the­o­ry that is truly mind-blowing: that we ex­ist with­in a vast mul­ti­verse, where oth­er uni­verses are con­stantly pop­ping in­to ex­istence,” said Uni­vers­ity Col­lege Lon­don doc­tor­al stu­dent Ste­phen Feeney, a col­la­bo­ra­tor on the re­search. Feeney cre­at­ed a for­mu­la to de­ter­mine wheth­er a mod­el with or with­out col­li­sions would bet­ter fit a wealth of cos­mic mi­cro­wave back­ground da­ta from NASA’s Wilkin­son Mi­cro­wave An­i­sot­ro­py Probe space­craft.One of dilem­mas fac­ing phys­i­cists is that hu­mans are very good at no­tic­ing pat­terns that may be there only by co­in­ci­dence. But the new for­mu­la is de­signed to be very hard to fool, im­pos­ing very strict rules on wheth­er the da­ta fits a pat­tern or wheth­er the pat­tern is down to chance. “It’s all too easy to over-interpret in­ter­est­ing pat­terns in ran­dom da­ta, like the ‘face on Mars’ that, when viewed more close­ly, turned out to just a nor­mal moun­tain,” not­ed Im­pe­ri­al Col­lege’s Dan­iel Mort­lock, a co-author of the re­search.The search based on da­ta from the NASA probe has turned up four candidate areas in the micro­wave back­ground that could be the sig­nature of a col­lision, ac­cord­ing to the re­search­ers. But noise in the data makes a definitive conclusion impossible, they added; new da­ta cur­rently com­ing in from the Eu­ro­pe­an Space Agen­cy’s Planck sat­el­lite should help solve the puz­zle.

    • Yup, it is funny how we non scientific people get to the answers long before the scientific community are willing to admit that "the common folk" have figured it out on our own through intuition and just plain common sense.  They seem to be always lagging, lol.  I thought the article was interesting though, that FINALLY they are figuring out what we already had figured out....
