Could this universe be inside a black hole?
What would be the implications if our universe existed within a black hole?
Would the singularity in a black hole affect dark matter? If so, in what way? Is it possible to have the event horizon of a black hole without a singularity? Could the singularity of a black hole be a graviton? Could the big bang have been a black hole exploding? If a black hole was heading towards our sun, what would happen? Wouldn't the event horizon of a black hole be a sphere around the central mass? What happens if a black hole die? Is a black hole really a hole? What is a black hole? What is a black hole? What does a black hole consist of? What happens after the lifetime of a black hole ends? What is the event horizon in a black hole? Are black holes and singularities related? Is it possible that the big bang came from an exploding black hole? Assuming that the Big Bang is a white hole, then won't it become impossible to find out what happened between the singularity and the event horizon? What would happen if a black hole collided with Earth? How do we know what we think are black holes aren't actually dark matter? As ALL matter is created soon after the Big Bang, and in a relatively small area, why doesn't it collapse into a black hole under its own gravitation? What is an event horizon of a black hole? Are there an estimates for the amount of dark matter a black hole contains? Which equation in general relativity predicted the existence of black-holes ? What does "the singularity in a black hole is a future moment in time" mean for someone inside the event horizon? What is it like in a black hole? What is a black hole singularity? Do all galaxies have a black hole? Is Earth a black hole? What is a black hole made of? If our sun was replaced by a black hole of equal mass, would anything happen to our orbit? Can gravitons escape the event horizon of a black hole? If not, how can we detect the black hole's gravity?
