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

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 ...

If you wave your hand in front of your face, you won’t notice anything particularly interesting. Perhaps a gentle waft of air against your cheek – that’s about it. No epiphany. No major sign that ...

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.

Comet 3I/ATLAS reaches its closest point to the Sun today, facing a final test of Avi Loeb's 'alien ship' theory. Will it ...

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 ...
