Dark matter detector may have accidentally detected dark energy instead

• https://newatlas.com by Michael Irving

Now, Cambridge scientists have proposed an answer that wasn't considered at the time – the experiment may have picked up the first direct detection of dark energy, the mysterious force that's accelerating the expansion of the universe.

Although it's thought to outnumber regular matter five to one, dark matter remains elusive. It doesn't interact with light and seems to mostly make itself known through gravitational influence on cosmic scales, like stars, galaxies and galaxy clusters. But once in a while, a dark matter particle might bump into a regular matter particle in a way that we could detect, with the right equipment.
