What’s on the other side of a black hole? That’s one of the biggest mysteries in space science! Black holes are super strong gravity pits, so once anything crosses the "event horizon" (their point of no return), it gets pulled in and can’t escape—not even light. Scientists think that matter inside a black hole might get squished into a tiny, dense point called a "singularity." Some theories suggest there could be a "white hole" on the other side that spits out what black holes take in, or even a wormhole that leads to a different part of the universe. But since nothing can escape a black hole, we can’t actually peek inside.
