Consider a scenario with two stars at a distance X from each other, each having the same mass M. Now, if one of the stars suddenly collapses into a black hole, as suggested by some scientists, and the distance between the black hole and the nearby star remains constant, and the mass of the black hole is equal to that of the original star, then the gravitational force experienced by the nearby star should not undergo significant changes.

The gravitational force between two objects depends on their masses and the distance separating them. As long as the mass and distance factors remain constant, the influence of the collapsing star (black hole) on the nearby star should not experience substantial alterations.
