Astronomer here! With all the black hole news lately, it's worth a reminder that black holes are NOT like giant vacuum cleaners that "suck everything in" or similar. This is a common misconception and not at all how black holes work! 🧵 First of all, worth covering what a black hole *is*. It is a region where the gravity is so strong that nothing- light, particles, etc- can escape. The area beyond which things can't escape is called the "event horizon" marked in this @ehtelescope pic of the black hole M87*.
