Expanding universe
Maybe elemental questions . 1. But if the Universe is expanding - and considering all the individual masses in space - is warping space time, then how could it expand. Or does the whole space/time warp caused by the mass - expand with it ? And what does it leave behind ? An un-warped area ?
2. They said they detected - great "winds' coming from Black Holes. I thought nothing could escape a black hole - even light. ??
3. Dark energy. Does this too - warp space/time ? Or does it have no mass. Just energy?
