Physicists have chased a unified description of nature for more than a century, yet quantum theory and gravity have ...

Quantum theory and general relativity have long described the universe with incompatible languages, one speaking in ...

In the end, the Universe becomes a place where gravity and quantum physics slowly turn all mass into faint streams of particles.

According to Einstein’s Theory of Relativity, space and time are inextricably connected. In our Universe, whose curvature is barely measurable, the structure of this spacetime is fixed. In a ...

On this week's episode of Spacetime, Gabe talks about what it actually means for a line to be straight so we can better understand what we mean by the idea of "curved Spacetime". This is Part One of ...

The connection between quantum physics and the theory of relativity is extremely hard to study. But now, scientists have set up a model system, which can help: Quantum particles can be tuned in such a ...

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 ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. This article is more than 4 years old. An illustration of heavily ...

Photons are indeed massless, but they still travel through our universe. You can picture the fabric of the cosmos as a sort of grid — one that is four-dimensional and incorporates not only the three ...

Oftentimes, we think of space as an endless, mostly empty vacuum, a silent backdrop where planets, stars, and galaxies play out their dance. We also think of time as something separate, a steady ...
