What is the attractive force between all matter in the universe?

Gravitational force

Explanation:

As we know that there are four fundamental force in nature

1) Gravitational Force : It is always attraction type of force which exist between two objects of different masses.

2) Electromagnetic force : It may be of attraction or repulsion type of force depends on the charge or pole of the given object.

3) Weak or strong nuclear force : This force depends on the distance between the particles. For a certain range of distance this force is of attraction type force while for other range it is repulsion type of force.

So here from above description we know that only gravitation force is the attraction type of force for all conditions so here correct answer will be

Gravitational Force

The attractive force between all matter in the universe is gravity.
