Time dimension and black holes
5 April 2014 | by (Cairo) – See all my reviews

Tyson specifically in this episode can simplify the time dimension for most of people even those who are not interested in science. I find this episode is the best of the past four episodes.

Even the reality of black holes can be explained in a simple way with the help of the great script and the genuine explanation by Tyson.It can correct the wrong thoughts about it from Sci-Fi movies.

I liked the way of connecting the past or the history of cosmos to the present time, even making deductions about the future of this universe, passing through times with explaining the evolution of known universe and supportive visual effects and graphics made it easier to make a simple imagination about what we are surrounded by and to know more cosmos.
