Mapping the road to quantum gravity

The road uniting quantum field theory and general relativity – the two great theories of modern physics – has been impassable for 80 years. Could a tool from condensed matter physics finally help map the way?

Alan Guth on new insights into the 'Big Bang'

Earlier this week, scientists announced that a telescope observing faint echoes of the so-called "Big Bang" had found evidence of the universe's nearly instantaneous expansion from a mere dot into a dense ball containing ...
