Looks like time travel is possible … for particles of spark .
Using a photon , physicist have managed tosimulate quantum particles traveling through clip . Studying the photon ’s behavior could help scientists sympathise some inexplicable aspects of modern purgative .
" The question of clock time travel features at the interface between two of our most successful yet ill-sorted forcible theories – Einstein ’s worldwide theory of relativity and quantum mechanics,“University of Queensland ’s Martin Ringbauersays in anews release . " Einstein ’s theory describes the world at the very turgid scurf of stars and wandflower , while quantum grease monkey is an splendid description of the world at the very modest scale of molecule and molecules . "
Time slow down down or speed up reckon onhow fast you move relative to another objective . Einstein ’s theory suggests the possibility oftraveling backwards in timeby take after a space - time path that returns to the start period in space – but at an earlier time . This is call a shut timelike curve ( pictured above ) . It ’s a travelable wormhole .
In a quantum authorities , the authors say , the paradox of time travel can be resolved , leaving shut timelike curve logical with Einstein’s theory of relativity . Near a black hole , for exemplar , the extreme effects of general relativity play a function .
image above , a quad - time construction exhibiting shut paths in space ( horizontal ) and time ( vertical ) . A quantum particle travels through a wormhole back in time and riposte to the same location in space and time .
" The properties of quantum particles are ' muzzy ' or uncertain to start with , so this gives them enough wriggle room to ward off inconsistent time travel situations,“UQ ’s Tim Ralph explains . " Our subject provides insights into where and how nature might behave otherwise from what our hypothesis prognosticate . " These admit the violation of Heisenberg ’s doubtfulness principle , cracking of quantum cryptography , and utter cloning of quantum states .
