Gravity, in the literal sense, keeps everyone (and everything) on Earth grounded. It acts as the anchor that prevents objects from floating skyward. For humans, it’s a leash that stops us from ...

To what extent has Earth’s gravity shaped our cognitive and brain functions? Utilizing spaceflight and a ground-based analog, a new study shows that the human brain relies on bodily gravitational ...

Accelerometers turn motion into measurable signals. From tilt and vibration to g-forces, they underpin countless designs. In this “Fun with Fundamentals” entry, we demystify their operation and take a ...

The idea of emergent gravity is still new and requires a lot of assumptions in its calculations to make it work. But if experimental evidence ever proves it real, we would need to totally rewrite the ...
