The search for quantum gravity is the next big step in physics, as researchers seek to unify the physics of the very small ...

Fragments of energy may be the fundamental building blocks of the universe. The theory combines the ideas of particles and waves into a concentration of energy that flows throughout space and time.

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 ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

As 3I/Atlas neared its closest point to the sun in its orbit, the internet was abuzz with curiosity about the comet.

Exploring the BTZ black hole in (2+1)-dimensional gravity took me down a fascinating rabbit hole, connecting ideas I never expected—like black holes and topological phases in quantum matter! When I ...

In some ways, a wormhole might look like a black hole. And the wormhole would look like a sphere, not a hole. Einstein's theory of general relativity allows for the possibility of wormholes, but there ...
