Weak Gravity Is Explainable With 10 Million Billion New Discovered Particles

Out of the four, gravity is one most fundamental force we are familiar with. It keeps Earth rotating around the Sun, and it makes up our every morning when we try to leave the bed. Gravity looks so familiar and until now it is the most mysterious force of all.

Gravity is extremely weak. Yes, it looks strong for us because Earth is massive, but even a little magnet can overcome gravity. The weakness of gravity is good update for us, planets and stars can form, but it does not actually fit well in particle physics. We have no way to describe why gravity should be so weak. A new concept, N naturalness, has a fascinating solution to describe weak gravity. Instead of having three relations of particles (each with two quarks, an electron-like particle, and one neutrino), there are in fact 10 quadrillion (1016) relations.

Co-author Tim Cohen, from the University of Oregon in Eugene told New Scientist, "The idea is a little wild. The lack of new physics at the LHC has inspired us to, instead of presenting a few new particles, introduce 1016 new particles."

This concept needs a single kind of particle working during the first moments of the Big Bang, called a reheaton. This particle would decay in the course of the cosmic inflation, and meanwhile particles desire to be in the lowest possible energy state, the resulting ‘allowed’ particles are the identified members of the Standard Model along weak gravitational relations. The billions upon billions of never- seen-before particles might seem slightly ridiculous, but it is not the first theoretical physics indication that uses a large number of parameters to find a suitable solution. It is ordinary that constants and laws of the universe fall into a certain array, and when this principle seems to be violated (like a weak gravity, crystal-perfect for us), it could specify that there is more science for us to explore in that direction.

The Standard Model does deliver us with the best explanation of particle physics, but we know it is limited, so physicists are searching beyond it both in theory and experimentations. Some of the claims of N naturalness can be verified by current experiments, so we might quickly see if this strange idea has some truth behind it.
