A new theoretical framework shows how subtle fluctuations in spacetime could be detected using existing interferometers.

Gravity used to be the most dependable rule in the cosmic rulebook, the quiet background force that never changed its mind.

Physicists have long treated space and time as the stage on which quantum particles perform, not as actors in the drama themselves. A new theoretical framework now flips that script, treating space ...

Hoboken, N.J., July 14, 2025 — Quantum networking is being rapidly developed world-wide. It is a key quantum technology that will enable a global quantum internet: the ability to deploy secure ...

Can a single particle have a temperature? It may seem impossible with our standard understanding of temperature, but ...

However, to measure spacetime fluctuations with an interferometer, we need to know where—i.e. at what frequency—to look, and what the signal will look like. With our framework, we can now predict this ...

Quantum mechanics is rich with paradoxes and contradictions. It describes a microscopic world in which particles exist in a superposition of states—being in multiple places and configurations all at ...

Is Time A Fundamental Part Of Reality? A Quiet Revolution In Physics Suggests Not. Time feels like the most basic feature of reality. Seconds tick, days pass and everything from planetary motion to ...

This article was published in Scientific American’s former blog network and reflects the views of the author, not necessarily those of Scientific American Conventional wisdom has it that putting the ...
