fraser, The problem with exploring a black hole is that it's a one-way trip. Good news: NASA has created a new simulation that takes you through a black hole's event horizon without all that messy spaghettification. The simulation was made using a supercomputer and provides two experiences. One is where an astronaut flies close to the black hole but then returns to space, and the other is a second, one-way journey directly across the event horizon boundary.
