When students learn that Albert Einstein won a Nobel Prize, the assumption feels automatic: relativity. The bending of space ...

Like stretch marks left on skin that expanded too quickly or cracks embedded in freezing ice, cosmic strings are artifacts of ...

Researchers at Stevens Institute of Technology and Yale University are initiating a first-of-its-kind experiment designed to detect gravitons, the hypothesized quantum building blocks of gravity.

110 years ago today, Albert Einstein published his General Theory of Relativity, which redefined the relationship between matter and gravity. Suddenly, our mysterious universe made a little more sense ...

Science continually evolves, moving away from once-accepted theories that now seem outdated. This video explores five significant theories that were replaced by more accurate explanations, ...
