Over the past two decades, scientists have widely grown to accept the idea that the universe is expanding at an accelerating pace, driven by the mysterious ‘dark energy.’
The discovery, initially made in the 1990s, has earned a Nobel Prize in Physics and birthed the current ‘standard model’ of cosmology – and now, a team of physicists say it might be wrong.
In a new analysis using a dataset ten times larger than the original, physicists argue that a key pillar of the model is ‘rather shaky,’ with the notion of dark energy arising from an oversimplified theoretical model constructed more than 80 years ago.
In contrast to the current understanding on the behaviour of the universe, they say it instead may be expanding at a constant rate without the help of dark energy.
