Lost Horizons: The Big Bang

To coincide with the switch-on of the Large Hadron Collider, the world's largest particle accelerator complex, Professor Jim Al Khalili from the University of Surrey 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

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. … Ler mais

Cosmic Dawn: The Real Moment of Creation

Horizon investigates the cosmic dawn, the moment one hundred million years after the big bang when the first stars were born

Forget the big bang. The real moment of creation was the cosmic dawn – the moment of first light. This is the scientific version of the story of Genesis.

The big bang gets all the credit for creating our universe. But in fact, the universe it gave was dark and boring. There were no stars, no galaxies, just a vast, black fog of gas – the cosmic dark ages.

But, after a hundred million years of nothing, … Ler mais
