The other day I saw Michio Kaku saying scientists now think that the universe "may have" started from being puked out by a blackhole from another universe. If this is correct could the answer to the question " why is the universe still expanding" be " It is still expanding because the said black-hole "is still spewing", into our universe, undetectable dark matter "that is still being devoured" in the universe in which it was born. If this correct it now begs for more answers to even more questions. For example: Could multiple black-holes be spewing into our universe at this very moment? :Could some black-holes in our universe be "giving birth" to new universes? : Are all black-holes the beginning of a new universe? The questions go on and on and on.... and these are just the questions coming from a dummy like me, lol, but you get the point!! I know I am not supposed to speculate but my curiosity has gotten the better of once again, lol,. I'm sorry if I am doing/done something wrong!!! Thank you!!!! Peace Brothers and Sisters!!!!!
