Just like Thanos inAvengers , our physical jurisprudence are obsessed with balance and symmetry . But the universe does n’t really assign to that . Physics tell us that subject and antimatter are equal and should have survive in adequate form after the Big Bang , but in reality , we have a universe made almost exclusively of matter .

We have no solvent for this fulgent discrepancy , it is a limit of our current theories . Many root have been aim to explain it , but they are all yet to be confirmed . Now , a recent and rather outlandish fresh theory suggests that our universe has a mirror anti - matter companion flesh out backward in clock time from the Big Bang . This hypothesis is represent in the journalPhysical Review Letters .

Before we get into the detail of this " mirror macrocosm " it ’s important to understand where the idea comes from . Since the fifties , scientist have strike that certain phenomena have the power to rape some long - institute isotropy of the universe of discourse .

One is call conservation of parity ( phosphorus ) , which is the idea that if you riffle all your spatial coordinate ( up becomes down , in becomes out , left becomes correct ) , physics will still behave in the same way . Another one is called charge ( C ) , which posits switching matter for antimatter should result in the same cathartic . But that ’s not always the cause . At first many of these misdemeanor were solve by using the immix CP symmetry , but then researchers found violation in this too , so they summate sentence ( triiodothyronine ) to the equation . The principle goes that something may be able to break   one ( or two ) of the symmetries of physics , but nothing should be able to fall apart the combinedCPTsymmetry .

This new study uses this advance for the total macrocosm . They reason that the universe does n’t violate CPT as our matter - dominate universe , expanding in a sure direction in time from the Big Bang , is the mirror image of an anti - matter dominated universe that existed before the Big Bang .

This theory has some interesting advantage . It does n’t require us to build novel physics to explain several complicated events in the organic evolution of the world , such as Cosmic Inflation , the extremely rapid expansion of the cosmos in the fraction of seconds after the Big Bang . It also come up with a potential nominee for dark matter , as this frame-up would produce an excess of monumental hypothetical particle known as sterile neutrino .

It is , however , far from a perfect theory . It does n’t explain for example the temperature fluctuation in theCosmic Microwave Background – the universe should be make full with radiation that is the remnant heat leave over from the Big Bang after the flatulency cooled   – which has been a base of cosmologic models since their discovery . The team is form onsolving these payoff . And if they do they can also state us if the mirror cosmos is populate by malevolent versions of ourselves .
