ELI5: If en­ergy cannot be created or destroyed, what happens to the ener­gy and matter that gets sucked into black h­oles?

Black holes do not violate these conservation laws.

Think of a penny that you drop into an ocean. For any practical purposes, that penny is gone, but that doesn't mean it just disappeared, it's still somewhere deep in that ocean.

Black holes don't destroy energy, they just "trap" it, if that makes sense.
