Black Hole Formation Stars are affected by two main forces: Nuclear fusion, and gravitation Black Holes are the result of an imbalance of these two forces. Nuclear fusion- the outward force from the star's centre and gravitation- the force pulling inwards. These two processes balance one another until all the star's hydrogen is exhausted, allowing gravitation to take over. Once gravitation dominates, the star becomes unstable and starts to collapse. As the core compresses, it …showed first 75 words of 718 total…

If an object collapses to within its Schwarzschild radius, it becomes a black hole. The radius is named after German astronomer Karl Schwarzschild, who derived the first model of a black hole in 1916.
