| The universe is expanding at an accelerating rate, or is it? Posted: 21 Oct 2016 09:32 AM PDT Five years ago, the Nobel Prize in Physics was awarded to three astronomers for their discovery that the universe is expanding at an accelerating pace. This led to the widespread acceptance of the idea that the universe is dominated by a mysterious substance named 'dark energy' that drives this accelerating expansion.
