One of the best documentaries ever made to encourage exploration of the self and the world around us, as humankind, is Cosmos: A Personal Journey. Carl Sagan had an exuberance that was infectious and it encouraged many to pursue an education into the sciences. To think that it can be followed up by a sequel, Cosmos: A Space Time Odyssey, has to be a challenge. Can anyone demonstrate the same zest that Sagan had as a presenter? Who is able to do the job? Patrick Stewart, the man who came to fame as the Captain of the Enterprise in Star Trek: The Next Generation or Michio Kaku, a theoretical physicist who has presented many an invigorating documentary about the universe around us, are very capable.
