In 1998, two teams of scientists measured the universe's rate of expansion, expecting to find it slowing down on route to a collapse. But instead, they found the opposite- the universe's expansion appears to be accelerating, having expanded more in the latter half of its life. In attempting to explain this mysterious behaviour, they revived one Einstein's long-since-forgotten ideas.
