This would have massively altered the course of the evolution of the Universe completely different big bang and stellar nucleosynthesis. Chemistry could be virtually non-existent! Featured on Meta.

When the strong force gets its claws on a proton, it pulls the proton firmly to the nucleus. The strong force is approximately times larger than the Coulomb repulsion. You may have heard about subatomic entities called quarks.
These are the tiny constituents of neutrons and protons. Quarks come in several types, and three of them are present in each proton and each neutron.
Quarks have a variety of interesting properties, but what's important for our discussion is how they interact. They interact via the strong force! In fact, the strong force interaction "leaks out" of each proton and neutron, producing the nuclear strong force that binds the nucleus together. So, at its root, an atomic nucleus is held together by a force that reaches out from the very quarks within the neutrons and protons.
Armies of physicists smashing atoms together with tremendous energies have verified all of this. Physicists call these "atom smashers" accelerators. There are linear accelerators, ring accelerators, and colliding beam accelerators, to name a few.
The results of these collisions are recorded and examined in painstaking detail. It is hoped that one day, scattering experiments will enable us to determine more fundamentally the nature of the origin of force itself. How absurd! No physicist knows. But I do! Read Col. But there are a number of important facts to be learned here, e. And, we owe that fact to nuclear physicists. Although there will be those who do such research only in an attempt to prove God does not exist, I believe the more we find out about the Universe and how it functions, the more there is to lead us to belief in its Creator.
These factors, coupled with the tight packing of protons in the nucleus so that they can exchange mesons creates enough strong force to overcome their mutual repulsion and force the nucleons to stay bound together. This really very helpful regarding the basic point of holding the nucleus…. Well, the strong nuclear force is one of the four fundamental forces of nature, and answering what produces it is therefore a very deep and mysterious question.
