Curious connections between physics and math suggest to Latham Boyle that space-time may survive the jump to the next theory of reality. The post Can Space-Time Be Saved? first appeared on Quanta Magazine

A 1930s-era breakthrough is helping physicists understand how quantum threads could weave together into a holographic space-time fabric. The post If the Universe Is a Hologram, This Long-Forgotten Math Could Decode It first appeared on Quanta Magazine

A black hole formula worked out in the 1970s remains the most concrete clue physicists have about the threads of the space-time fabric. The post The #1 Clue to Quantum Gravity Sits on the Surfaces of Black Holes first appeared on Quanta Magazine

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 post The Search for What Shook the Earth for Nine Days Straight first appeared on Quanta Magazine

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.

An ultra-precise measurement of a transition in the hearts of thorium atoms gives physicists a tool to probe the forces that bind the universe. The post The First Nuclear Clock Will Test if Fundamental Constants Change first appeared on Quanta Magazine

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. The post How the Higgs Field (Actually) Gives Mass to Elementary Particles first appeared on Quanta Magazine

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.
