What Happened Before the Beginning?
Every cosmologist and astronomer agrees: our Universe is 13.7 billion years old. Using cutting-edge technology, scientists are now able to take a snapshot of the Universe a mere heartbeat after its birth. Armed with hypersensitive satellites, astronomers look back in time to the very moment of creation, when all the matter in the Universe exploded into existence. It is here that we uncover an unsolved mystery as old as time itself – if the Universe was born, where did it come from? Meet the leading scientists who have now discovered what they believe to be the origin of our Universe, and a window into the time before time. The big bang theory holds that the entire universe was once packed tightly into an unimaginably dense and tiny space, known as a “singularity.”
Professor Jim Al Khalili delves into over 50 years of the BBC science archive to tell the story behind the emergence of one of the greatest theories of modern science, the Big Bang. The remarkable idea that our universe simply began from nothing has not always been accepted with the conviction it is today and, from fiercely disputed leftfield beginnings, took the best part of the 20th century to emerge as the triumphant explanation of how the universe began. Using curious horn-shaped antennas, U-2 spy planes, satellites and particle accelerators, scientists have slowly pieced together the cosmological jigsaw, and this documentary charts the overwhelming evidence for a universe created by a Big Bang.

The Big Bang
They are the most powerful objects in the universe. Nothing, not even light, can escape the gravitational pull of a black hole. Astronomers now believe there are billions of them out in the cosmos, swallowing up planets, even entire stars in violent feeding frenzies. New theoretical research into the twisted reality of black holes suggests that three-dimensional space could be an illusion.
Through the Wormhole: The Riddle of Black Holes
Only a man with the brain the size of Stephen Hawking’s would seriously accept the challenge of answering the question How did the universe begin? in less than 30 minutes, while making it accessible for the population at large. Hawking’s lecture is a masterclass in concision and clear- thinking. He spins through the history of thought on the subject, beginning with the early Biblical view that the world was created by God around 6,000 years ago. And that wasn’t the only cockamanie theory dreamt up in the succeeding millennia. Up until the 20th century, mainstream thinking viewed the universe as eternal, a static expanse that had no beginning or end, and where, as Hawking supposes, “nothing very exciting ever happened”.
How Did the Universe Begin?
It seems there is no real division between the mind and the body. Both work together as part of the human whole and changes in one influence the other. Nothing is all in the mind, or just physical. We seem to be extraordinary mixtures of mind and matter, able almost to use one to create the other, explains this documentary film. Each one of us certainly has the power and science now has given us the means to take personal responsibility for our own well-being.
Natural Mystery
What Happened Before the Big Bang?
They are the biggest questions that science can possibly ask: where did everything in our universe come from? How did it all begin? For nearly a hundred years, we thought we had the answer: a big bang some 14 billion years ago. But now some scientists believe that was not really the beginning. Our universe may have had a life before this violent moment of creation. Horizon takes the ultimate trip into the unknown, to explore a dizzying world of cosmic bounces, rips and multiple universes, and finds out what happened before the big bang.
The Universe: Beyond The Big Bang
Documentary that explores how mankind came to understand the Universe and its origins in the Big Bang. From the earliest people who looked up at the sky and wondered about its nature to modern physicists like Einstein, Gamow, Alpher And Guth. The universe began with a massive expansion, billions and billions of years ago, and it continues to expand with every passing second. The idea that the universe, and man’s very existence, began with a “Big Bang” is no longer a topic of debate among most scientists – it is essentially taken as fact.
