Physicists have established the existence of a latest form of atomic nuclei, and the information that it’s not symmetrical challenges the basic theories of physics that give details our Universe.
But that's not as bad as it sounds, because the detection could help scientists solve one of the largest mysteries in theoretical physics - where is all the dark subject? - and could also explain why travelling backwards in time might actually be not possible.
But that's not as bad as it sounds, because the detection could help scientists solve one of the largest mysteries in theoretical physics - where is all the dark subject? - and could also explain why travelling backwards in time might actually be not possible.
"We've establish these nuclei literally point towards a way in space. This relates to a way in time, prove there's a well-defined direction in time and we will always travel from record to present," Marcus Scheck from the University of the West of Scotland told Kenneth MacDonald at BBC News.
So let’s back up here, since to understand this new form of atomic nuclei, you have to get to identify the old ones first. Until recently, it was recognized that the nuclei of atoms could be one of presently three shapes - spherical, discus, or rugby ball.
These shapes are formed by the sharing of electrical charge within a nucleus, and are dictate by the specific combination of protons and neutrons in a sure type of atom, whether it’s a hydrogen atom, a zinc atom, or a complex isotope shaped in a lab.
The ordinary factor across all three shapes is their symmetry, and this marries nicely with a theory in particle physics known as CP-Symmetry. CP-symmetry is the mixture of two symmetries that are consideration to exist in the Universe: C-Symmtery and P-Symmetry.
C-Symmetry, also recognized as charge symmetry, states that if you flip an atomic indict to its opposite, the physics of that atom should motionless be the same. So if we get a hydrogen atom and an anti-hydrogen atom and mess with them, both should react in identical ways, even though they have conflicting charges.
P-Symmetry, also recognized as Parity, states that the the spatial coordinates telling a system can be upturned through the point at the origin, so that x, y, and z are replace with −x, −y, and −z. While physicists have supposed that Barium-144 has a pear-shaped nucleus for some time at the present, Scheck and his team lastly figured out how to directly observe that, and it turns out its bend is even more pronounced than predict.
So what does all of this have to do with time tour? It's a pretty out-there hypothesis, but Scheck says that this uneven distribition of mass and allege causes Barium-144's nucleus to 'point' in a sure direction in spacetime, and this bias could give details why time seems to only want to go from past to present, and not backwards, still if the laws of physics don't care which way it goes.
Of course, there's no method of proving that without further evidence, but the detection is yet another indication that the Universe strength not be as symmetrical as the Standard Model of Physics requests it to be, and prove that could usher us into a whole latest era of theoretical physics.
