Hi i am new member looking to learn from you guys Can any one answer these questions if so ui would be most grateful. Is there more than just one Universe. Is it known where our Universe starts and ends. Do we need to know the outside edges of our Universe before we can find the centre of it. Is the sun really the centre of our Universe. If it definately is the centre is the centre of our Universe - how do we know it is. Thanks in advance, Fagin.
