For example, why is the strong nuclear force strong enough to hole protons and neutrons together.

Physics really isn't about that kind of "why" question. We observe what nature does and physics is the framework in which we describe it to the best of our abilities.KarminValso1724 said:For example, why is the strong nuclear force strong enough to hole protons and neutrons together.
The 4 fundamental forces (gravity, electromagnetism, strong nuclear force, and weak nuclear force) are the only forces that have been observed and studied in the universe. While there may be other undiscovered forces, the 4 that we know of are the most fundamental and have the greatest impact on the behavior of matter.
The strengths of the 4 forces were determined through various experiments and observations. For example, the strength of gravity was measured through the motion of planets and stars, while the strength of electromagnetism was determined through the behavior of charged particles. The strength of the strong and weak nuclear forces were also determined through experiments involving subatomic particles.
The strengths of the 4 forces are believed to be a result of the different properties of the particles that mediate them. For instance, gravity is mediated by the graviton, which is a massless particle, while the strong nuclear force is mediated by the gluon, which has a much larger mass. These differences in particle properties ultimately affect the strength of the force they mediate.
The strength of the 4 forces can change under certain conditions, such as extreme temperatures or energies. For example, at very high energies, the electromagnetic and weak nuclear forces are believed to merge into a single unified force. Additionally, it is theorized that in the early universe, the strong and electroweak forces were also unified.
The 4 forces work together to govern the behavior of matter and energy in the universe. Gravity is responsible for the large-scale structure of the universe, while electromagnetism governs the interactions between charged particles. The strong nuclear force holds atomic nuclei together, and the weak nuclear force is responsible for radioactive decay. All 4 forces play a crucial role in the functioning of the universe as we know it.
