text: Hi there, \n\nA very challenging question...There are many speculations regarding the extent of the universe. Some say that the universe is ever expanding with no boundary. And some say that it will expand only to a certain extent and start coming closer again to right back where it started from. But we never know!! It is said that the universe is made up of 'Dark Matter' , the composition of which has not been explained clearly till date. \n\nSo it is very difficult to theorize n state one particular answer for your question. I would suggest you read the book 'A Brief History of Time' by Stephen Hawking. It has many theories and facts. I'm afraid I haven't been of much help. \n\nrule wid style n luv@vinny
