Welcome to the 5th dimension: Our universe's radical new fate
17 July 2019
Our best models of cosmology suggest the universe will either go on forever, implode or rip itself apart. A new proposal suggests an even weirder destiny

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 was wrong: Why 'normal' physics can't explain reality
14 November 2018
The most ambitious experiments yet show that the quantum weirdness Einstein famously hated rules the roost – not just here, but across the entire universe
Quantum mechanics may contradict itself when applied to big objects
18 September 2018
Standard quantum theory explains the behaviour of microscopic things like electrons and atoms. It should also, in principle apply to larger objects – but it might not
Quantum stopwatch could be the best in the universe
22 May 2018
Storing time from a quantum stopwatch with qubits – instead of losing accuracy by stopping and starting it – could give us the ultimate precision in timekeeping
Entangled clouds of atoms are quantum record-breakers
26 April 2018
Two distinct clouds of ultracold atoms have been entangled for the first time, which could help us figure out where quantum effects begin and end
The big fudge: Welcome to the theory of not-quite-everything
11 April 2018
Physicists from Einstein to Hawking tried and failed to unite gravity and quantum theory. Now we have hints of a better – but not so beautiful – answer
We see neutrinos from the big bang in the way galaxies cluster
4 April 2018
Just after the big bang, waves of neutrinos and other matter raced across the cosmos. Those neutrinos reached forward in time to dictate where galaxies form now
Dark radiation may fix our broken understanding of the universe
20 March 2018
We have two ways to measure the accelerating expansion of the universe, but they don’t line up. If dark matter gives off radiation, it could make them agree
Quantum trick lets one particle send messages two ways at once
26 February 2018
For two people to send each other a message, it usually takes a minimum of two particles. But quantum superposition makes it possible with just one
