All of the objects in our solar system are acted upon by forces. Forces are pushes or pulls. Every force has both a strength and a direction. Applying a force on something–like pushing a toy car–can ...

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 ...

For more than a century, gravity has been the stubborn outlier in physics, perfectly described on cosmic scales yet refusing to mesh with the quantum rules that govern everything else. A growing camp ...

Robert Monjo, Ph.D., mathematics professor at Saint Louis University-Madrid, has introduced a theory that may transform scientists' understanding of gravity and its relationship to quantum physics.

Dr Charles Buhler takes people through his lab in a new video. He explains more about how they developed and detected a new force from large electrostatic pressure differences. They claim this force ...

A new study suggests that gravity could quantum-entangle particles even if it remained classical.

Is gravity just an emergent effect of entropy? Gravity might not be a more fundamental than the force of a stretched elastic band. Maybe gravity is just an entropic byproduct—an emergent effect of the ...

A new study in the journal Nature examines the distribution of dark matter in the universe, attempting to figure out if it obeys the same laws as regular matter. What it found suggests that dark ...

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