escape velocity
velocity needed to escape the gravity of an object
4
New cards
supermassive
really large and is center of every galaxy
5
New cards

New cards
what would happen to you if sucked by a black hole
start to fall toward singularity, body gets stretched and ripped in half

New cards
what would happen to earth if sucked by a black hole
gravity of black hole affects tides making tidal range miles, atmosphere sucked into black hole, anything not bolted to ground gets sucked in, earth gets sucked in
