We could be living inside a black kettle of fish . This caput - spin idea is one cosmologist ’s conclusion based on a modification of Einstein ’s equations of general relativity that changes our picture ofwhat happen at the Congress of Racial Equality of a black hole .
In an analysis of the movement of subatomic particle get into a black yap , published in March , Nikodem Poplawskiof Indiana University in Bloomington show up that inside each black-market hole there could be another universe of discourse ( Physics Letters B , DOI : 10.1016 / j.physletb.2010.03.029 ) . “ peradventure the huge black golf hole at the centre of the Milky Way and other galaxies are bridges to dissimilar creation , ” Poplawski say . If that is right – and it ’s a big “ if ” – there is nothing to rule out our cosmos itself being inside a black hole .
InEinstein ’s general relativity(GR ) , the insides of black holes are “ singularities ” – region where the concentration of matter reaches eternity . Whether the singularity is an actual point of multitudinous compactness or just a mathematical inadequacy of GR is unclear , as the equations of GR divulge down inside black holes . Either manner , the modified version of Einstein ’s equations used by Poplawski does away with the singularity tout ensemble .
For his psychoanalysis , Poplawski turned to a random variable of GR call the Einstein - Cartan - Kibble - Sciama ( ECKS ) hypothesis of somberness . Unlike Einstein ’s equations , ECKS gravitation takes chronicle of the spin or angulate momentum of elementary particle . include the spin of subject makes it potential to figure a property of the geometry of outer space - time call tortuousness .
When the density of matter progress to gargantuan proportions ( more than about 1050 kilogram per cubic meter ) inside a dim hole , crookedness manifest itself as a force that counter gravity . This prevents matter compressing indefinitely to reach multitudinous compactness , so there is no singularity . alternatively , says Poplawski , matter rebounds and starts expanding again .
Now , in what is certain to bea controversial subject field , Poplawski has apply these ideas to model the behavior of infinite - clip inside a black hole the heartbeat it starts rebound ( arxiv.org/abs/1007.0587 ) . The scenario resembles what happen when you compress a spring : Poplawski has calculate that gravity initially overcome torque ’s repulsive force and keep open compression matter , but finally the obscene power gets so impregnable that the matter stops collapse and rebound . Poplawski ’s calculations show that quad - time inside the black hole thrive to about 1.4 times its smallest sizing in as small as 10 - 46 bit .
This staggeringly fast saltation - back , says Poplawski , could have been what take to the expanding macrocosm we keep today .
How would we have a go at it if we are living inside a grim jam ? Well , a spinning black hole would have add some twisting to the space - metre inside it , and this should show up as a “ preferred instruction ” in our creation , say Poplawski . Such a favored direction would result in the irreverence of a property of space - time call Lorentz symmetry , which links blank and time . It has been suggested that such a rape could be responsible for for the discovered oscillation of neutrinos from one type to another ( Physical Review D , DOI : 10.1103 / PhysRevD.74.105009 ) .
If we are survive inside a black jam , it would have bring a ‘ special guidance ’ to our world
lamentably , there is no point in us expect for other universes inside black holes . As you near a black hole , the increase gravitational field makes metre tick slower and dim . So , for an external commentator , any new universe inside would form only after an infinite amount of prison term had elapsed .
