'they' (i don't know who they are)

keep listing Gravity

What year did Gravity become a ...force????

When it became a "fundamental interaction"

1. Gravity.
2. The weak force.
3. Electromagnetism.
4. The strong force.

These are called the four fundamental forces of nature, and they govern everything that happens in the universe.

.... relativity says otherwise.

When not dealing with relativistic speeds, Nertwon's gravitational formulae work just fine. They enabled Newton to explain the astronomical observations of Kepler.
