Physicists are increasingly noticing a paradoxical tendency: sometimes proving the obvious is a more difficult process than proving the incredible. Here is another example taken from the latest research. Matter is the basis of everything in the universe, and this is obvious. Everything from your neighbor, noisy at night, to the most distant galaxy, is material. However, the laws of physics require symmetry. For every negative charge there is a positive one, and for every matter there is antimatter. So why don't we notice antiparticles around us, because they are formed, just like positively charged particles in the nuclei of active galaxies?
Perhaps a clue has been found
Astronomers argue that it is almost impossible to discern antimatter. On this score, a complete picture has not yet been formed, and only assumptions are made. Not long ago, an international group of physicists may have found a clue. Scientists have found that some atomic nuclei are not symmetrical, but pear-shaped.
Nuclear Theories Received Refutation
The researchers looked at isotopes of barium. One of them, barium-144, is not a spherical or oval regular shape. This is the reason for the fragility of the atom, because protons and neutrons inside it are distributed asymmetrically. Accordingly, a large mass is concentrated at one end of the nucleus, and a smaller one at the other. It is curious that this conclusion conflicts with some nuclear theories. For example, until now physicists could not prove the obvious - the impossibility of time travel. However, now humanity has a unique opportunity to do this.

Violation of the principles of symmetry
Particles that are distributed inside a pear-shaped shape violate the principles of CP symmetry (where C is charge conjugation and P is parity). In C symmetry, all differently charged particles behave the same way. So antihydrogen will behave like hydrogen. P-symmetry is oriented towards space, where any system must have a mirror image.
CP symmetry assumes that for every particle moving counterclockwise, there is an antiparticle moving in the opposite direction. But if scientists can fully prove the violation of the laws of symmetry, this will explain the absence of antimatter. It is worth noting that until now only a few confirmations of this theory have been found. And now another refutation has been found. The discovered atom, which has an asymmetric shape, is one more proof that not all the laws of physics fit into the standard model (theoretical construction in elementary particle physics).
How to apply it in relation to time
We know that the universe is symmetric about CPT (charge, parity and time). But if conditions C and P are violated, then the symmetry of T will also be violated. This only means one thing: things cannot travel back in time. The detected asymmetric nuclei literally indicate the direction in space. Time cannot turn back, and every "passenger" in the Universe has a one-way ticket.
