Trillions of neutrinos—nearly massless, neutrally charged particles—pass through us every second, but we only acknowledge ...

In 2023, a subatomic particle called a neutrino crashed into Earth with such a high amount of energy that it should have been ...

The way time ticks forward in our universe has long stumped physicists. Now, a new set of tools from entangled atoms to black ...

This puzzle is known as the problem of time, and it remains one of the most persistent obstacles to a unified theory of ...

Time feels like the most basic feature of reality. Seconds tick, days pass and everything from planetary motion to human memory seems to unfold along a single, irreversible direction. We are born and ...

The accelerating expansion of the universe is usually explained by an invisible force known as dark energy. But a new study suggests this mysterious ingredient may not be necessary after all. Using an ...

Physicists have long relied on the idea that electrons behave like tiny particles zipping through materials, even though quantum physics says their exact position is fundamentally uncertain. Now, ...

Dark stars powered by dark matter may explain bright galaxies, massive black holes, and mysterious red objects in the early universe.

Joining the traditional New Year’s resolutions, like losing some weight and getting more sales, European carmakers are fast approaching a new timeline in 2026, one that will forever change the ...

In a quiet corner of low-temperature physics, researchers have stumbled on a phase of matter that seems to break one of the field’s unwritten rules: it works without well-defined particles. Instead of ...
