Dr.Brian Cox is a popular Physicist who makes science interesting for young people. In this video he is speaking to the students and teachers of schools in the UK about the universe. Please see the video patiently till the end. We have discussed much of it in our meetings earlier but hearing from Prof. Cox is different. If you have any doubts note them down and I will clear them the next time we meet or you may leave a comment and I will try to clarify where ever possible.
