“This is where we get to the great irony of the story – because in the end it wasn’t the size of the asteroid, the scale of blast, or even its global reach that made dinosaurs extinct – it was where the impact happened,” said Ben Garrod, who presents the BBC documentary The Day The Dinosaurs Died (watch video below).

Both theories, crown jewels of 20th century physics, cannot be true at the same time. A Dutch theoretical physicist and string theorist, Erik Verlinde, proposes a starkly different theory –the theory of emergent gravity. “We might be standing on the brink of a new scientific revolution,” he says,”that will radically change our views on the very nature of space, time and gravity.”
