Gravity is the force of action between two objects. It’s called a natural force because it acts at a distance rather than needing to be in contact. Gravity is the force that holds us down on Earth and ...

Legend has it that Isaac Newton had the moment of inspiration that would lead to his theory of gravity when, on a warm ...

European scientists are turning an aircraft into a laboratory that simulates lunar gravity to prepare astronauts and ...

Did you know that gravity isn't the same everywhere on Earth? In Canada's Hudson Bay, gravity is slightly weaker than the global average—an anomaly scientists have been studying since the 1960s. As ...

New research conducted by nuclear physicists is using a method that connects theories of gravitation to interactions among the smallest particles of matter. The result is insight into the strong force ...

A new concept for energy transfer between gravitational waves and light. When massive cosmic objects such as black holes merge or neutron stars crash into one another, they can produce gravitational ...

I didn’t have an apple tree to sit under to understand gravity, but living in a skiing and mining town surrounded with steep, sloped mountains introduced me to gravity forces, both positive and ...

Aerodynamics explains how airplanes fly through the interplay of four fundamental forces: lift, weight, thrust, and drag.

The world of astronomy and everything that surrounds it continues to give us secrets that until now seemed unthinkable. In ...

Gravity and motion make time pass faster on Mars than Earth, reshaping navigation, communication, and future crewed missions.
