Black hole information paradox facts for kids

Kids Encyclopedia Facts

The black hole information paradox is a phenomenon in astrophysics. It is when quantum mechanics and general relativity are put together.

This phenomenon states that the information a physical system has can be lost when it enters a black hole. The object that falls into a black hole, only keeps information about its spin, mass and charge. However, the quantum mechanics says that information cannot be lost. This makes it a paradox.
