The question of how gravity interacts with the quantum world has long perplexed physicists, but a non-quantum theory of space-time could present an answer ...

It was the discovery that changed the universe - or rather our understanding of the universe. One hundred years ago today, Albert Einstein presented his theory of general relativity. So for the next ...
