Press space or tap to chuck a very unfortunate square into the hole. I tried to make this as accurate as possible with Scratch's blocks.
All code is by me. This "game" is a simulation of what it would look like if you watched something fall into a black hole from the outside. Since black holes bend space and time, you wouldn't see the object get sucked into the hole. You would see the object move oh so slowly to the hole, then stop at a point called the event horizon, which is where a black hole's gravitational pull is so strong you can't escape it. Then you would see the object red-shift, then fade. You would never see it cross the event horizon.
