Physics, Astronomy & Cosmology / Could Black Holes be Worm Holes?

« on: 26/11/2018 06:30:43 »

I've been thinking about Black Holes and Worm Holes and this is what I thought of: 'Since we don't know what is past the Event Horizon of a Black Hole. Could a Black Hole possibly be a Worm Hole? Or would it just kill you and add your mass to it's center.' What do you think?

General Science / Would this self-sustaining system work?

Hello! I have an idea for a self sustainable source of electricity, and I would like to know if it is possible.
    So, what I have on mind is that you have a circlular hole dug into the ground with a cylindar coming up from the center. You build lots of Hydroelectric dams in it in a spiral and make sure that they can transfer water through them. Then you start filling it with water. After it's full, you cut of the water suply and shouldn't it be able to sustain itself? Excluding the fact that you would have to put water in once in a while due to evaporation.
