The universe's four fundamental forces are as follows: 1. Gravity: Gravity is the force that pulls mass-containing objects (like planets, stars, galaxies, and other mass-containing objects) towards one another. 2.

Strong nuclear force: The strongest fundamental force in the universe, the strong nuclear force holds protons and neutrons together within an atom's nucleus. However, it is only active over very short distances within the nucleus. 4. Weak nuclear force: The weak nuclear force is the cause of some forms of radioactive decay and
