Black Hole

This simulation shows what you might see if you are orbiting a black hole. The light and position of background stars around the whole are distorted by its gravity and they seem to spin around. On the right, the constellation Orion appears to approach the event horizon, the boundary from which nothing can escape. Orion stars look like they become separated and get spun around. Once the hole has passed by, Orion reappears on the left and looks normal again. Users can also experiment with different scenarios. This is what you might see if you were traveling towards a black hole with rocket engines slowing your descent. Another simulation mimics free fall into a hole. In the middle, the light of the entire universe appears to be concentrated in a bright ring.
