In the Science channel I often hear vivid description of astronomers regarding the vastness of our universe...?

What they show was mind boggling, the vastness of the universe and explaining black holes, galaxy after galaxy, illions of stars and distances in billions of light years. Has the universe no end? Are our illustrious space scientists, philosophers, mathematicians and astronomers prepared to admit that there is INFINITY in space? Doesn't infinity mean that there is no end, that it goes on forever and ever? If there is no END, then there can't be a BEGINNING correct?
