Choose the correct option.
Correct answer: D. Newton discovered that gravity pulls everything towards it.
- A. Newton discovered that gravity pulled everything away from it.
- B. None of these is correct.
- C. Both of these are correct
- D. Newton discovered that gravity pulls everything towards it.
Explanation
Gravity pulls everything towards it - this is a universal truth. Universal truths are always expressed in the present tense even when narration is in the past. Therefore, the correct sentence is "Newton discovered that gravity pulls everything towards it."

About Law of Universal Gravitation
Every two masses attract each other with a force proportional to the product of their masses and inversely proportional to the square of their separation, expressed as F = Gm₁m₂/r². Questions also involve the gravitational constant, vector direction, superposition of gravitational forces, and the distinction between gravitational force and gravitational field strength.
