Could a black hole become large enough to consume the entire universe (given infinite time)?
Given enough time, will the whole universe become a black hole?
Can time survive in a black hole? Can a black hole be created inside a black hole? Is it true that black holes can make us travel through time like in movies? 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? Are there more theories for or against our observable universe (93 billion light years across) being inside a black hole? Is it possible to have the event horizon of a black hole without a singularity? Is it possible to think of black holes as having no spacetime inside the event-horizon? How does time pass 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? Can we travel through black holes? Would the singularity in a black hole affect dark matter? If so, in what way? Do we live inside a black hole? Can a black hole become a star again? Do black holes disappear eventually or will it keep getting bigger? Does time work in black hole? Are we inside a black hole? How do black holes impact time? What happens to the matter that forms a black hole? Can we artificially create a black hole? What happens to matter when it enters a black hole? Are we in a larger version of the outflow of a universal black hole? What happens after the lifetime of a black hole ends? Why does time cease to exist in a black hole? Can a black hole be moved? Can another black hole exist in a black hole? In Interstellar, it is shown that through black holes we can travel to the future. How? Can you survive a black hole? Is there a singularity inside the event horizon of a black hole? Could the big bang have been a black hole exploding? Could the singularity of a black hole be a graviton?
