Or would women be better off without men ??? Most of the latest technology suggests that which ever choice you make we could still reproduce either way. You don't need whom for a child to grow (at this point in time). But with men you would have to operate to deliver the child....Or you could just do it in a dish and incubate the foetus. I must admit nature is much cleverer than that and tricks US into expecting a reward for our efforts. I must admit it does work. Otherwise why would you put up with all the years cost and heart ache. But to put in the balance of the scales, all the years of love and affection.
A black-hole is not a hole it's a sphere. As will be the universe when compressed into the smallest unit it can be.
