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.

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 ...

The Universe may not have begun with a Big Bang, but instead with a Big Bounce, according to a new theory about how the ...

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 ...

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

"The singularity is the most mysterious and problematic part of a black hole. It's where our concepts of space and time literally no longer make sense." A team of scientists has developed a recipe for ...

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