what force is responsible for crushing or collapsing stars?\n nuclear fusion\n gravity\n light\n velocity
Answer
Brief Explanations:
Gravity is the force that pulls matter together. In stars, when the fuel for nuclear - fusion runs out, the outward pressure from fusion stops, and gravity causes the star to collapse inwards. Nuclear fusion provides an outward pressure to counter - balance gravity during a star's main sequence. Light and velocity are not forces responsible for star - collapse.
