After the big bang, atoms in gas clouds experienced a greater gravitational pull to each other than atoms in other regions of the universe. Which two statements are scientific facts that explain this phenomenon?

Gravitational pull on an object decreases with a decrease in its temperature.

As the density of an object increases, it becomes immune to gravitational force.

Gravitation between two objects increases when the distance between them decreases.

Gravity doesn’t exist between objects that are less than one light-year apart.

When the mass of an object increases, its gravitational pull also increases.

which 2 are correct?
