Final answer:
Every object with mass indeed exerts a gravitational force on every other object with mass, which is in line with Newton's Universal Law of Gravitation.
Step-by-step explanation:
The statement that every object with mass exerts a gravitational force on every other object with mass in the universe is true. According to Newton's Universal Law of Gravitation, this force is directly proportional to the product of the masses of the two objects and inversely proportional to the square of the distance between their centers. The law is summarized by the equation F = GM₁M₂/r², where F is the gravitational force, G is the gravitational constant, M₁ and M₂ are the masses of the objects, and r is the distance between their centers of mass.
