Scientists have taken lasers beyond light and into the realm of sound, creating a breakthrough “phonon laser” that ...

This Quick Question explains the difference between gravity and g-force, and how you can experience zero-g in space even when ...

General relativity stands as one of the bedrock theories in modern physics. Its strange view of relative time and space has been confirmed by countless experimental and observational tests, from ...

Waterloo scientists have developed a new way to understand how the universe began, and it could change what we know about the Big Bang and the earliest moments of cosmic history. Their work suggests ...

The International Space Station is humanity’s most expensive gym membership. Since the earliest days of human spaceflight, it’s been understood that longer trips away from Earth’s gravity can have a ...

Emergent gravity is a bold idea. It claims that the force of gravity is a mere illusion, more akin to friction or heat—a property that emerges from some deeper physical interaction. This emergent ...

Gravity’s always been my favorite force. I’ve been cheering from the front lines as it’s consistently exceeded expectations, mapping massive globs of invisible matter, bending light to magnify infant ...

We all know gravity as the invisible force that keeps us grounded. But what if it's not a force at all? What if it's a function? One physicist believes gravity might actually be one of the strongest ...
