Can You Answer These What If Hypothetical Questions?
What would happen if you fell into a black hole?
If you were to take a step into a small black hole, your body would most closely resemble toothpaste being extruded out of the tube. Tidal forces are so strong at a black hole's threshold (called the "event horizon") that they would stretch your body into a string of atoms as you fell into the abyss. But if you fell into a somewhat larger black hole with less extreme tides, you could maintain your internal structure. Einstein's theory of time dilation suggests that if you looked forward toward the black hole's center, you'd see every object that has fallen into it in the past. Behind you, you'd see everything that will ever fall into it in the future.
