You are a spiritual being that exists on the astral right now. With power meditation you will realize that. The physical universe is made up of matter, energy, space and time. You are not in the physical universe. You are animating a body in the physical universe. You are not a body! It is impossible for you to be "in" the physical universe! You never have been and you never will be in the physical universe. As a result of loosing everything you once knew in the way of spiritual power and knowledge, you believe your a body in the physical universe. Having a body to animate in the physical universe is nice and having one that is supposedly immortal is even better. Traversing the universe is done without your body. You don't have to die to leave your body. You leave your body every night when you sleep. It just takes the smallest sliver imaginable of body occupation to keep it working smoothly. The remaining part of you is free to travel anywhere your little heart desires. That's how you can traverse these Sci Fi things these idiot materialists made up. As far as the darkly dark "black holes" go... what Yog Sothoth said...
