The irreversibility of time may be a clue as to what makes up the universeâs dark matter.

One of the more curious challenges in physics is to understand the nature of time. At the microscopic level, the laws of physics are symmetric with respect to timeâthey work just as well whether time runs forwards or backwards. But at the macroscopic level, processes all have a preferred direction. The great physicist Arthur Eddington called this the âarrow of time.â
Just why this arrow points in one direction but not the other is one of the great scientific puzzles. The standard answer is that the arrow of time follows from the Second Law of Thermodynamicsâthat disorder, or entropy, always increases in a closed system.
Thatâs why milk mixes easily in tea but never emerges from a brew, why scrambled eggs never spontaneously unscramble, and why your morning mug of coffee heats your hands as you hold it and not the other way around.

This stunning image captured last year by physicists at the University of Glasgow in Scotland is the first-ever photo of quantum entanglement â a phenomenon so strange, physicist Albert Einstein famously described it as âspooky action at a distanceâ.
It might not look like much, but just stop and think about it for a second: this fuzzy grey image was the first time weâd seen the particle interaction that underpins the strange science of quantum mechanics and forms the basis of quantum computing.
Quantum entanglement occurs when two particles become inextricably linked, and whatever happens to one immediately affects the other, regardless of how far apart they are. Hence the âspooky action at a distanceâ description.
Carl Jung and Wolfgang Pauli bounced ideas off each other, Paul Halpernâs book shows.
Does the enormous computing power of neurons mean consciousness can be explained within a purely neurobiological framework, or is there scope for quantum computation in the brain?
Researchers pin down the contentious notion that ideas from the strange world of quantum mechanics underpin plantsâ skill at harvesting sunlight.
