A letter written by Albert Einstein in which he doubts the existence of God has been auctioned for $2.9m in New York.

By the time he died last March, the astrophysicist Stephen Hawking was convinced there was no God and no afterlife.

Albert Einstein's formula for a happy life was sold for $1.3 million (€1.1 million) at an auction in Jerusalem.

Gravity waves — ripples in spacetime — have been detected by scientists a century after Albert Einstein predicted their existence.

When he wasn’t busy scribbling out the theory of relativity, Albert Einstein seems to have spent a fair amount of time writing letters involving topics such as God, his son’s geometry studies, even a little toy steam engine an uncle gave him when he was a boy.
