... well, sort of. We might not have the brains of Stephen Hawking but this series allows us a little bit of insight into his genius way of thinking.
As he continues to explore some massive questions about the origins of the universe, this clip from the final episode in the mini-series explains the concept of negative energy in the simplest terms.
Professor Steven Hawking addresses another fundamental question in part two of Grand Design, his exploration of the nature of our universe.
This week, he considers the meaning of life. In our clip, you'll encounter Simulation Theory, just one of the many mind-expanding concepts that this wonderful and challenging programme introduces.
