Did you know black holes can slow down time when you're next to them? Pretty crazy, I know. And that's 1 reason why black holes are insanely important to the universe and the galaxy. And, more!
1. There is a lot we know about black holes, but we'll never fully know everything about black holes due to the fact that the galaxy is infinite. And there's not all that much reach to black holes considering how far away they are from Earth.
2. They're not portals, they're not wormholes, they're not portals to different dimensions or other universes. Even though they are very real, these things are not real facts. Some people think that! And it's OK, we're all still learning.
3. Black holes affect a lot in gravitational space. They're pretty crazy, because of how much of an affect that they have on the galaxy and it's gravitational space and matter and more. There's a lot of math that goes into it, but it's irrelevent for now.
4. During the mid 1960 to 1970s; there was a golden age of black hole research, and it caused several developments in research in black holes and it has influenced how much we know about black holes today, in the modern age of 2026.
