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?

How can we know what is happening at the edge of space at this moment in time, or indeed the universe itself, being as the edge of the observable universe is about 12 billion light years away and therefore the information we receive is that amount of time out of date? How do we know where our galaxy is now in relation to the whole of the universe? If what we are looking back in time all those billions of years, we cannot know the reality of the universe now, can we?
