Astronomers have long argued that dark matter is the invisible scaffolding that holds galaxies together. Without its immense ...

While direct evidence of multiple universes is hard to come by, indirect evidence raises intriguing possibilities.

Modern physics suggests distance may emerge from motion, gravity and quantum entanglement, not exist as a basic fact. (CREDIT ...

After the passing of physicist Anthony Leggett, columnist Karmela Padavic-Callaghan remembers their personal connection with ...

Astrid Eichhorn spends her days thinking about how the laws of physics change at the tiniest scales. Imagine zooming in closer and closer to the device on which you’re reading this article. Its ...

Scientists from Rensselaer Polytechnic Institute (RPI) have used mathematical concepts from string theory, a theoretical description of the mechanics of the entire universe, to upend over a century of ...

Cosmic strings are artifacts of what the universe looked like in the moments before it rapidly changed from a high-energy to low-energy environment—the Big Bang. Today, scientists believe cosmic ...

Why does string theory matter so much? 😳 Physicist Michio Kaku explains how this bold idea could unify the laws of physics, reshape our understanding of reality, and change how we see the universe.

Natural physical networks are continuous, three-dimensional objects, like the small mathematical model displayed here. Researchers have found that physical networks in living systems follow rules ...

Tinkering at their desks with the mathematics of quantum space and time, physicists have discovered a puzzling conundrum. The arcane rules of quantum theory and gravity let them imagine many different ...
