What does it mean to be to space-time? The seemingly simple question gets to the essence of twentieth-century physics and has ...

One of the biggest obstacles in physics is the inconsistency of time in quantum mechanics and general relativity. In quantum mechanics, time is an external and unchanging parameter.

For decades, quantum physics and general relativity have stood as two powerful but separate theories. Quantum physics explains the behavior of tiny particles like atoms and photons.

Scientists in Japan have uncovered a strange new behavior in “heavy” electrons — particles that act as if they carry far more ...

Textbooks give strange, imprecise explanations of where things happen in quantum mechanics. Consistency with gravity needs a fresh approach.

Physicists have struggled to understand the nature of time since the field began. But a new theoretical study suggests time could be an illusion woven at the quantum level.

For a century, quantum theory has passed every experimental test, but physicists can’t agree on how to use it to paint a ...

A survey of Scientific American’s century of quantum coverage helps explain the enduring popularity of strange physics ...

Clocks might be far more fundamental to physics than we ever realized. A new theory suggests what we see around us – from the smallest of quantum actions to the cosmic crawl of entire galaxies ...

Quantum researchers have deployed a new algorithm to manage noise in qubits in real time. The method can be applied to a wide ...

A new theory suggests that “time” might be the product of a universe that, long ago, decided to settle down into one definitive story, sparking reality as we know it.
