Does the black hole hold a gateway to another universe?
Would a black hole be the exit of this universe?
What happens after the lifetime of a black hole ends? Would the singularity in a black hole affect dark matter? If so, in what way? What would happen if the black hole in the center of the milky way would evaporate? Are we in a larger version of the outflow of a universal black hole? What happens if a black hole die? Can we kill a black hole? Is there a singularity inside the event horizon of a black hole? Are there more theories for or against our observable universe (93 billion light years across) being inside a black hole? Could the arrow of time associated with the Big Bang actually be the time associated with the outflow of a universal black hole? Are we in the outflow of a larger version of a supermassive black hole? Is dark energy caused by the outflow of a universal black hole? Is it possible to have the event horizon of a black hole without a singularity? What happens to matter that enters a black hole? Can gravitons escape the event horizon of a black hole? If not, how can we detect the black hole's gravity? What is the event horizon in a black hole? How universe will come to an end? What would happen to a person if he enters a black hole? Can a black hole be moved? Wouldn't the event horizon of a black hole be a sphere around the central mass? What happens to matter when it enters a black hole? Could the big bang have been a black hole exploding? What happens if a black hole comes into our solar system? How will the universe end? When will that happen? What is an event horizon of a black hole? Is it possible that the big bang came from an exploding black hole? How did this gravitational wave manage to escape the event horizon of the two black holes? What percent of physicists believe our universe was born from a black hole? Would we be inside the black hole or separate space-time via a white hole? What would happen if you were swallowed by a black hole? What happens when someone enters the black hole? Could the singularity of a black hole be a graviton? Is the Big Bang a black hole in reverse?
