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
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
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
Parallel universes could solve a big problem with black holes
20 December 2017
The black hole firewall paradox has been vexing physicists for years. But if quantum laws lead to the creation of other universes, the headache disappears
Space-time and gravity might be born from the quantum world
18 December 2017
To reconcile quantum mechanics and gravity, a new theory flips the usual script. Space-time and gravity may emerge from quantum effects, not the other way round
Free-fall experiment could test if gravity is a quantum force
15 November 2017
The effort to reconcile general relativity with quantum mechanics always hits one snag: gravity. An experiment could finally tell us if it is a quantum force
Light’s quantum weirdness survives after going to space and back
25 October 2017
Photons act both like waves and particles, and their dual nature has now been seen even after bouncing them off a satellite in low Earth orbit
The geometry that could reveal the true nature of space-time
26 July 2017
The discovery of an exquisite geometric structure is forcing a radical rethink of reality, and could clear the way to a quantum theory of gravity
