"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.
& the greatest answer of all
Prof Dr Amar V: See the bottom right of your monitor if you are reading this in Windows OS. If you are using other OS change it to Windows & then see the bottom right corner. (Oh commooooon, I took a lot of time for this line & my effort deserves atleast a smile.)
In this BBC Horizon program, Prof Brian Cox meets various physicists & tries to explain several questions such as what is time, how is it calculated accurately (quasar, atomic clock), is it even possible to calculate it, etc,. Along the journey to find answers, Einstein's General Relativity & Quantum Physics are also slightly brushed.
This is a very very interesting & fun programme from BBC Horizon. The graphics are very impressive & editing is good. There are some cool scenes such as the one where Brian is shot with an ultra slowmotion camera or the one showing Hubble space telescope's picture of our universe when it is only 700-800 million years old. I felt very thrilled seeing that early universe picture.
A highly recommended program. If you got any time to spare, google this title & watch it unless you hate physics or astronomy.
LOL..funny, and fact too!
