So, does cosmo offer any detail of "others factors so far missed that were at play"? Or is s/he simply grasping at straws in assuming some fudge factor which reconciles the observable evidence of an SN1987A 160,000 years ago and an unchanged speed of light with cosmo's desire to fit all events inthe universe within a 7,000 year time period which is dictated by his/her interpretation of a religious text?
Time to put up observable evidence or shut up about a young universe having any reality other than in the minds of those with a particular religious bent.
