**New Theories / Do we live in a Black Hole?**

Is the Universe a giant black hole? How can we tell? Recall John Wheeler's one-sentence summary of general relativity:

Maybe our universe is a black hole in a larger universe. If we assume that mass continues to accelerate toward the singularity after crossing the event horizon then it is traveling backward in time. From our perspective inside the event horizon it is travelling forward in time and everything outside the event horizon is traveling backward in time. What looks like expansion to us (if we live in a small enough patch) would look like contraction toward a singularity from outside the event horizon.

*"Spacetime tells mass how to move; mass tells spacetime how to curve."*Maybe our universe is a black hole in a larger universe. If we assume that mass continues to accelerate toward the singularity after crossing the event horizon then it is traveling backward in time. From our perspective inside the event horizon it is travelling forward in time and everything outside the event horizon is traveling backward in time. What looks like expansion to us (if we live in a small enough patch) would look like contraction toward a singularity from outside the event horizon.
