An “anti-universe” the place time runs backwards may exist subsequent to ours, in line with a brand new examine.
The idea entails the very fact nature has elementary symmetries and researchers suppose this might apply to the universe as a complete.
The idea has been defined in the journal Annals of Physics.
It discusses a typical physics idea known as Cost, Parity, Time (CPT) symmetry.
CPT symmetry is acknowledged as one of many legal guidelines of physics and means issues like cost and time might be inverted after a transformative course of.
Scientists suppose the Massive Bang, which created the universe, was positively transformative and due to this fact the CPT principle may apply.
The researchers suppose that there was a ‘backwards universe’ earlier than the Massive Bang that was then inverted to create the universe we stay in at the moment.
They defined: “We examine the concept the universe earlier than the Massive Bang is the CPT reflection of the universe after the bang, each classically and quantum mechanically.”
And, added: “The universe earlier than the bang and the universe after the bang could also be seen as a universe/anti-universe pair, rising immediately into the new, radiation-dominated period we observe in our previous.
“This, in flip, results in a remarkably economical clarification of the cosmological darkish matter.”
The wild principle may imply the presence of darkish matter in our universe isn’t so mysterious in any case.
The scientists suggest darkish matter is definitely made up of a kind of ghostly particle known as right-handed neutrinos.
Neutrino particles are current in our universe however they solely spin to the left.
Scientists suppose it’s odd that they haven’t discovered a model that spins to the suitable because the legal guidelines of physics recommend they need to be on the market.
The researchers suppose the suitable spinning particles could possibly be invisible in our universe and will simply be represented by darkish matter.
Little is thought about darkish matter within the universe aside from it can’t be seen however does have a bodily impact on different objects.
Researchers suppose investigating neutrino particles and darkish matter additional may probably be a step in proving the ‘anti-universe’ principle.
Scientists don’t suppose we’d be capable of go to the proposed ‘anti-universe’ as a result of it technically occurred earlier than the Massive Bang.
