Why does time fly or drag? How emotions warp our temporal perceptions

Why does time fly or drag? How emotions warp our temporal perceptions

15 June 2022

Felt time can speed up and slow down, depending on circumstances, because our perception of duration is intrinsically linked to the mental states induced by our physiological responses to the world


How do we make the most of our time? The power of confronting death

How do we make the most of our time? The power of confronting death

15 June 2022

Our species' unique awareness of our own mortality can create a nagging sense that we are wasting our time – but leaning into the fact that our time is finite can transform the way we approach life

How long does evolution take? It happens on two different timescales

15 June 2022

To make sense of the fact that adaptation can happen quickly and yet true evolutionary change seems to take forever, biologists suggest that evolution runs on two very different clocks


8 Can we live without time?

Can we live without time? Not if we value a solid sense of self

15 June 2022

Ditching artificial light and living by the natural cycle of the sun can offer plenty of benefits for your health. But when you lose any sense of time whatsoever, you risk losing yourself too


JILA?s three-dimensional (3-D) quantum gas atomic clock consists of a grid of light formed by three pairs of laser beams. A stack of two tables is used to configure optical components around a vacuum chamber. Shown here is the upper table, where lenses and other optics are mounted. A blue laser beam excites a cube-shaped cloud of strontium atoms located behind the round window in the middle of the table. Strontium atoms fluorescence strongly when excited with blue light.

Jun Ye interview: What use is the world's most accurate clock?

15 June 2022

The most advanced atomic clocks don’t just tell time – they could soon get so ludicrously accurate that they could be used for detecting gravitational waves and testing the limits of relativity


Will time ever end? The answer lies in the death throes of the cosmos

Will time ever end? The answer lies in the death throes of the cosmos

15 June 2022

The universe might meet its end in a big freeze, a big crunch, or a big rip. But whether time ends with the demise of the cosmos depends on whether it is even real after all

Will we ever unite physics? Clocks in superposition could offer clues

15 June 2022

Physicists have long sought to marry general relativity and quantum mechanics – now some reckon experiments that probe the way each theory treats time could finally make it happen


3 How Do We Sense Time? Mechanical brain, conceptual image. Composite image of coloured medical imagery of a human brain and skull, with cogs and gears representing concepts such as memory, time and mechanical brains. The imagery includes 3D computed tomography (CT) scans of the skull and 3D magnetic resonance imaging (MRI) scans of the brain. The scans are of a 30-year-old woman.

How do we sense time? The brain cells that order our memories

15 June 2022

Recent studies suggest there is not one part of the brain dedicated to measuring duration, as there is for senses like taste and smell. Instead, the passage of time is tracked by a network of “time cells”


Could we ever go back in time? Relativity does not rule it out

Could we ever go back in time? Relativity does not rule it out

15 June 2022

The physics thought to explain the arrow of time is not as simple as you might think – and in traversable wormholes, Einstein’s theory of general relativity does in principle offer routes to the past
