Of the four known fundamental forces of nature, the weak nuclear force is the one with the least obvious purpose. Gravity holds stars together and keeps us on the ground. The electromagnetic force ...

In the very early, very hot moments of the universe, the electromagnetic and weak nuclear forces were actually the same force ...

That at least is the case with the strong nuclear force, one of four fundamental forces of nature (the others being electromagnetism, gravity and the weak nuclear force). The strong force holds ...

and which is also responsible for holding atoms together), the weak nuclear force (which acts inside atomic nuclei, and is responsible for a certain kind of radioactive decay), and the strong ...

So, detecting their presence is challenging to say the least. They are formed through the actions of the weak nuclear force, which governs radioactive decay. It is this force that enables ...

And the reason could be evidence of a new, fifth force of nature. Currently, there are four known forces of nature: gravitational, electromagnetic, and the strong and weak nuclear forces.
