As he says..."Check this out". I am enthusiastic about the universe, and I own most of the documentaries on this subject,and so far I Can tell you this one, is one of the best.
Stephen Hawking, is truly one of the brightest minds since Albert Einstein. In this excellent series, he uses his genius brain to explain some of the most interesting themes such as alien life, origins, and time travel. I particularly like time travel the most.
You'll be surprised to learn that time travel is not only possible, but even is happening right here, right now on earth.
Every subject is explained with a simplicity and a good sense of humor (Stephen is a surprisingly good-humored person), which does not let you get bored. The images are fantastic in high definition. The best thing, of course is the privilege of seeing one of most intelligent mind in action . THANK YOU PROFESSOR HAWKING FOR THE RARE OPPORTUNITY.
