Step 1: Understanding mass and volume in space
In space, some regions contain an extremely large amount of mass concentrated into a very small volume.
Step 2: What are black holes?
These regions are known as black holes. They have such strong gravitational pull that nothing, not even light, can escape from them.
Step 3: Formation of black holes
Black holes are often formed from the remnants of massive stars after they collapse under their own gravity at the end of their life cycle.
