Time

The laws of physics imply that the passage of time is an illusion. To avoid this conclusion, we might have to rethink the reality of infinitely precise numbers.

A new look at a ubiquitous phenomenon has uncovered unexpected fractal behavior that could give us clues about the early universe and the arrow of time.

The brain can’t directly encode the passage of time, but recent work hints at a workaround for putting timestamps on memories of events.

On November 16, 2018, more than 200 readers joined writers and editors from Quanta Magazine for a wide-ranging panel discussion that examined the newest ideas in fundamental physics, biology and mathematics research.

A recent experiment shows how quantum mechanics can make heat flow from a cold body to a hot one, an apparent (though not real) violation of the second law of thermodynamics.

Time isn’t just another dimension, argues Tim Maudlin. To make his case, he’s had to reinvent geometry.

There’s more than one good way to bring order to our unruly, seemingly arbitrary calendar.

How our society defines years, months and weeks can seem frustratingly arbitrary. Can you bring order to our unruly calendar?

The effort to unify quantum mechanics and general relativity means reconciling totally different notions of time.
