Searching for the past and future of quantum physics on a tiny island
17 June 2025
According to scientific legend, quantum mechanics was born on the island of Helgoland in 1925. A hundred years later, physicists are still debating the true nature of this strange theory - and recently returned to the island to discuss its future
Rethinking space and time could let us do away with dark matter
13 March 2024
Most physicists believe that only a quantum theory of gravity can fully explain mysteries of the universe like dark matter, but now an idea called "post-quantum gravity" is demonstrating an alternative approach
It may be possible to traverse a wormhole and then send a signal home
20 December 2022
When matter falls into a wormhole, the wormhole is expected to collapse – but a probe may be able to send a signal back through before it’s trapped on the other side
Quantum nature of gravity may be detectable with gravitational waves
30 August 2021
Perhaps the most important problem in physics is how gravity and quantum mechanics fit together, and strange fluctuations in gravitational waves could help us figure it out
Did pre-big bang universe leave its mark on the sky?
9 April 2008
According to a model based on "loop quantum gravity" theory, a parent universe that existed before ours may have left an imprint
