"This work is a step toward understanding how quantum mechanics and gravity work together, a major unsolved problem in ...

Here is a force diagram of a person on the surface of the Earth and a person in the space station with "fake gravity". The person on the ground has the two forces that are equal in magnitude (thus ...

This means that the artificial gravity force is mostly constant, ... Imagine that they are going from position 1 to position 2 in the diagram below. Illustration: Rhett Allain.

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.

Is gravity even a force at all? We've been through the first few episodes of our crash course on general relativity, and came out alive! But it's officially "time" for CURVED spacetime.

I prefer the "theory" that there is no gravity force at all. That it's all electromagnetism. Ever since I saw a craft the shape of a small river barge (30'X10" approx.) floating by my house one night.

The first year of data from the 5,000 robotic eyes of DESI shows Einstein's theory of general relativity is the right recipe for gravity despite the challenges of dark energy and dark matter.

You may have heard that gravity isn't a force. This is true. Gravity is not a force; however, this truth leaves us with a number of questions. For example, we're commonly told that gravity "pulls ...

If gravity is a quantum mechanical force, adjacent free-falling masses, each of which is in a superposition of being in two places at once, could get entangled by gravity such that measuring the ...

The crowning achievement of the 18th-century researcher was the design of the first experiment to measure the force of gravity between masses in a lab. Skip to main content.
