I am sad to observe the intellectual level of our younger generation via the comments below. Its my request not to use bad language. He is teaching astrophysics in urdu. We should be thankful to him. Focus on the topic rather than his views. Everyone has views. Lets learn to respect views no matter how hard. Shabash

@juggernaut boister :human being is not a zerox machine that will exactly copy something,it requires mind,original thinking even in understanding things,when someone tells you or learn through a book!it's not general knowledge whose answers are fixed,its science in which everything depends on intelligent thoughts of discovering and researching! What he is explaining is not a cake walk,if it were that easy,than i challenge you to make same video with more or equal clarity than professor!
