The universe may be hiding a fundamentally unknowable quantum secret
29 January 2026
Even given a set of possible quantum states for our cosmos, it's impossible for us to determine which one of them is correct

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
How to destroy a black hole
16 April 2024
A black hole would be tough to destroy, but in the season two premiere of Dead Planets Society our hosts are willing to go to extremes, from faster-than-light bombs to time travel
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
We may finally know how blazars act as cosmic particle accelerators
23 November 2022
Supermassive black holes that beam powerful jets of matter towards Earth, known as blazars, accelerate particles to extraordinarily high energies – and astronomers have finally figured out how
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
Quantum experiment suggests there really are ‘alternative facts’
22 February 2019
A complex probe of the foundations of quantum mechanics suggests that the nature of reality depends on who is looking – there are no objective facts we can agree on
Einstein kills Schrödinger's cat: Relativity ruins quantum world
16 June 2015
The same quirk of general relativity that means your head ages faster than your feet may mean we have to go to space to see large-scale quantum mechanics in action
Fiery black hole debate creates cosmological Wild West
5 February 2014
Bids to solve the black hole firewall paradox are producing a free-for-all in theoretical physics – cue time reversal, walls of ice and bouncing stars
