Part 3/12:

Responsible for radioactive decay, the weak nuclear force enables particles like neutrons to transform into protons and vice versa. It plays a vital role in the processes powering the sun and other stars, governing how subatomic particles change identities.

The Strong Force

The strongest of the four, the strong nuclear force binds quarks together to form protons and neutrons, and consequently holds the atomic nucleus intact. Its magnitude is billions of times greater than gravity, ensuring the stability of matter itself.

Understanding these forces is pivotal—they form the foundation of our current "model" of physics. They are the insurmountable pillars that keep the cosmos in order, and their perpetual operation is essential for the universe's existence.
