These three imagined scenarios lead many physicists to doubt that space-time is fundamental.

Until his dying days, the giant of 20th-century physics obsessed over the underpinnings of space and time, and how we can all share the same version of them.

This special issue of Quanta Magazine explores the ultimate scientific quest: the search for the fundamental nature of reality.

Last year, an immense but brief outburst of seismic energy was soon followed by a long hum that made the world ring. Finding its cause took 68 scientists and an assist by the Danish military.

The Industrial Revolution brought us the laws of thermodynamics, and new ideas about work, energy and efficiency. In this episode, co-host Steven Strogatz speaks with theoretical physicist Nicole Yunger Halpern about what these concepts might mean in the age of quantum mechanics.

In this article adapted from his new book, "Waves in an Impossible Sea," physicist Matt Strassler explains that the origin of mass in the universe has a lot to do with music.

Since Newton had his initial revelation about gravity, our understanding of this fundamental concept has evolved in unexpected ways. In this week’s episode, theoretical physicist Claudia de Rham and co-host Janna Levin discuss the ways our current understanding of gravity needs to continue to evolve.

While devising a new quantum algorithm, four researchers accidentally established a hard limit on entanglement.

For decades, extremal black holes were considered mathematically impossible. A new proof reveals otherwise.
