If scientists know how the universe is made then what will happen from that – what kind of benefit would they get from it?
Like space time is the black stuff of space and gravity related in the same way? We know that galaxies are spinning to fast to stay together. They say it is the black stuff that stops or controls them from flying apart. So does gravity and the black stuff work together, and cannot be separated?

If the big bang exploded out of a really dense material, is there that material again at the centre of our universe now getting ready to do it again and has the process been repeated before?
