Thank you kind sir for your patience and answer. I know very little science but it is something of interest to me after watching a Brian Cox documentary. I think you must be correct that I have ventured to junk sites. I am glad I have found this science site as I have so many questions about the Universe and the replies are from kind sirs who know what they are talking about. Thank you . Is there any possibilities you know of that could cause the Universal expansion? Do you have any of your own ideas of how the expansion is occurring?
