Mathematical formulas written over a hundred years ago could find an echo in the most current theories about black holes and ...

Even the best telescopes can’t see exoplanets. It’s all about watching for jiggly stars, blue shifts, and transits.

Heron of Alexandria was an important ancient Greek inventor of mechanical devices whose inventions included the first steam ...

The findings not only advances scientists' understanding of what quantumness really means over time, but also points to new ...

Nuclear clocks are a technology researchers have been working toward for decades. New research in theoretical physics brings them closer to reality.

Even worse, the orbit of Mars is elliptical (think of a slight oval rather than a perfect circle), which means that sometimes ...

Clocks on Mars tick faster by about 477 microseconds each Earth day, a new study suggests. This difference is significantly ...

The Hubble tension is especially troubling because it involves two sets of measurements that offer conflicting views of the ...

New measurements using gravitational lensing suggest the universe’s current expansion rate does not agree with signals from ...

Three thought experiments involving “demons” have haunted physics for centuries. What should we make of them today?

Current physics is speeding toward a breaking point, as astronomers confirm that the Hubble tension in new data.

A Star Trek–inspired idea by Miguel Alcubierre kicked off decades of theory and experiments as scientists pursue plausible ...
