I like to discuss the in my opinion absurdity of the age of the universe claims that are made. How can there be such a thing as one age in for people who have an understanding of SR and GR? For an object that travelled at light speed during the big bang explosion the age of the universe is zero. For other objects is may be longer or shorter than from the perspective of earth. So what's up with those absolute numbers? Looks pretty meaningless to me.
