Scientists might have found the fifth fundamental force of nature
Now, scientists have found a new force which is expected to be the fifth force present in the universe.
There are four forces that we know about and formulas and laws are made based on the assumption of their existence. Now, scientists have found a new force which is expected to be the fifth force present in the universe.
The fifth force of Nature:
This force has been observed in a helium atom and also in an isotope of beryllium a few years ago. The particle that carries this force has been termed as X17.
The particle is 33 times bigger than an electron and has a short life-span of about 10 to the minus 14 seconds. Its presence is confirmed in various ways, including its interaction with neutrons. It also behaves differently than the other four forces known to us.
The detection process:
Earlier, scientists bombarded protons at a lithium-7 atom. It caused the decay of the atom and the emission of pairs of electrons and positrons. According to the standard model of physics, the angle separating the trajectory of these particles should increase.
As the energy of the particles increases, the angle should decrease. Or, the number of pairs coming out should decrease as the angle between these particles increases. At 140 degrees the number of pairs jumped and then decreased further creating a bump. This bump is said to be a new particle, boson, containing the fifth type of energy.
How is it useful?
It is expected to help us understand the forces that govern our universe. The new particle containing the new force might also help us in understanding the invisible matter expected to be existing in space. It can also solve the mystery of the existence of dark matter. The findings are yet to be peer-reviewed and need a lot of experimentation before it gets a confirmation by the scientific community.
Other known Forces:
Gravity, a force that keeps us glued to the earth, the weak force found in subatomic particles, electromagnetism, forces found between electrically charged particles and the strong force is the strong nuclear forces found inside the atoms.
