"What Time Is It?" asks Prof Brian Cox at the end of the BBC Horizon program Do you know what time it is?
Some of the answers given by physicists are
Prof Irwin Shapiro: That depends. Are you talking about Universal time? Are you talking about Eastern time?
Prof Steven Beckwith: It's 13.7 billion years. That's what time it is.
Dr Dennis McCarthy: It's not an easy question to answer.
Dr Fay Dowker: A great time to be a physicist.
Prof Saul Perlmutter: Just about time to go home & have dinner.
Prof Max Tegmark: It's a great question although some great questions actually turn out to be trick ones.
Prof Neil Turok: The time today is something we have no idea about.
Prof Brian Cox: We might not be in a position at this moment in time with our current understanding of nature to even understand what it is that we are asking.
