If this theory is true… nothing is outside the universe. #BlackHole #Universe #SpaceFacts

Some physicists propose a shocking idea: our universe may be the interior of a black hole formed in another universe. The expansion of space, the one-way flow of time, and the limits of what we can observe may all match the physics of an event horizon. If true, the Big Bang wasn’t a beginning — it was a collapse.
