The Universe's expansion may be slowing down

New study suggests current theories of dark energy could be wrong

- 

The prevailing Nobel Prize-winning theory that the Universe is expanding at an ever-accelerating rate due to the unseen influence of dark energy has been called into question by a new study.

Astronomers at Yonsei University in South Korea found evidence that the 'standard candles' used to measure cosmic distances and calculate how fast the Universe is expanding may not be as standard as thought. These 'candles' are Type la supernovae, exploding stars that all reach a consistent, well-known peak of brightness, meaning the dimmer the Type la supernova, the farther away it is.
