Werner Heisenberg (1901-1976) was a German physicist who helped to formulate quantum mechanics at the beginning of the 20th century. He first presented the Heisenberg Uncertainty Principle in February 1927 in a letter to Wolfgang Pauli, then published it later that year. Heisenberg’s Uncertainty Principle states that it is impossible to know both the exact position and the exact velocity of an object at the same time. However, the effect is tiny and so is only noticeable on a subatomic scale.
It is that the universe and all of the matter and energy out of which we are created was created in a great explosion about 15 billion years ago. This was the big bang. Most scientists will agree with this but there are a few, experts in the field, who understand that we still really don’t know. Most of us are intrigued by questions to do with the origin and evolution of the universe. Where do we come from? Where are we going?

From trees to clouds to humans – after watching this film you’ll never be able to look at the world in the same way again. Find out more about the secret life of chaos. Professor Jim Al-Khalili sets out to uncover one of the great mysteries of science, how does a universe that starts off as dust end up with intelligent life? How does order emerge from disorder? It’s a mind-bending, counterintuitive and for many people a deeply troubling idea.
Time Trip is a thrilling journey deep into the strangeness of cutting-edge physics, a place where beautiful, baffling ideas are sometimes indistinguishable from the utterly crazy. On this journey, we meet a time-travelling pizza, a brilliant mathematician in a ski mask and even God. The journey ends with a strange and dark conclusion, one which calls into question our very existence.
By revisiting the beginning of time, scientists hope to unravel some of the deepest secrets of our Universe. Within these first few moments the building blocks of the Universe were created. The search for these fundamental particles has occupied scientists for decades but there remains one particle that has stubbornly refused to appear in any experiment.
