Carlo Rovelli on the bizarre world of relational quantum mechanics

Physicist Carlo Rovelli explains the strange principles of relational quantum mechanics - which says objects don't exist in their own right - and how it could unlock major progress in fundamental physics

The cosmos doesn't work to my research schedule – but that's OK

In November 2019, researchers were astonished when they viewed its image captured by the Hubble Space Telescope. Dark matter is an invisible substance that astronomers believe plays an important role in the formation of galaxies and is thought to comprise 85 percent of the universe?s mass. This discovery not only challenges the ideas of how galaxies form, but also provides evidence that dark matter is real. It shows that dark matter is not always coupled with regular matter in galaxies and that it has its own separate existence. In addition to lacking dark matter, galaxy NGC 1052-DF2 is an anomaly because you can see straight through it. This is called an ultra-diffuse galaxy because it has an extremely low density. As a result of these findings, a team of researchers are hunting for more dark-matter deficient galaxies to better understand the nature of dark matter and the formation of galaxies.

W0MN5G This undated NASA/ESA Hubble Space Telescope image shows the galaxy IC 335 in front of a backdrop of distant galaxies. IC 335 is part of a galaxy group containing three other galaxies, and located in the Fornax Galaxy Cluster 60 million light-years away, December 30, 2014. As seen in this image, the disc of IC 335 appears edge-on from the vantage point of Earth. UPI/NASA
