Forgive me for my ignorance, for this is my first post, but this specific topic caught my eye, and i was hoping for a brief answer on a question relating to the subject.
People are claiming that it would be impossible for a universe to travel through a black hole (ala worm-hole), but my question is- would it be hypothetically possible for a black hole to grow massive enough (bearing in mind that that would take an inprobable amount of time) for it to encompass and 'suck up' an entire galaxy? And if so, is there any scientific evidance that would show that black holes are restricted to a certain mass/size (i.e. can only grow so big).
Now if it was possible for it to encompass an entire galaxy (and therefor hypothetically possible for it to suck up galatic clusters, etc... ergo the mini-verses) Then would all of the mass and energy of the mini-verse be 'inside' the black hole? And, if it was restricted to get so big- would it be in any way at all likely that it could reach a point where-by it would collapse upon itself and all of that trapped energy would be forced out? And (there is ALOT of presuposition with this) could this be what scientists claim to be the big bang?
As of yet, i have no research to back any of this up, bar brief examples found on other webpages. I was only wondering if anyone else had drawn a similar hypothesis and knew alot more about black holes than i do
