i think black holes are powerfull enogh they can cluster and center and in spiral galaxcies and when two galixies colide they even out and become larger then so one and so on all matter exists and reforms and eventaully comes together into a single point where the power is so great that time is reformed because of matter and in the center time is was and never will be a black hole i belive is time travel not because its a wormhole or dumb Language Removed like that but because it is so powerfull it exceds time and before you could make it there it wasnt there and all matter reforms and only could exist where time stands still they are eternal and when its all together everything is as it was in the last begining and everythig reforms as it was perfectly in the void of space because everything is matter and the energy is the same at that one point no matter which why it`s turned a void is a void.
