Let's file this post under "mistakes that Rhett made that he doesn't want to make again." If I don't write it down, I won't learn from my mistakes. How about I start this with the following problem.

A new crew of potential ripples in spacetime has just debuted — emphasis on the word “potential.” By loosening the criteria for what qualifies as evidence for gravitational waves, physicists ...

We define and explain mathematically through multiple example problems. Segment 4E: Gravitational Potential and Kinetic Energy Gravitational potential energy and kinetic energy are defined and ...

Potential energy is the energy stored of position by an object. It is a type of energy that can be converted to other forms and related to some attractive or pushing forces. Gravitational potential ...

Zone of divergence: A section through the centre of mass, O, of a planet and the single point, S, on the surface of the planet that touches its Brillouin sphere. The point O is the centre of the ...

This week, a team of physicists published a paper in the journal Physical Review Letters with more than 1,000 contributing authors. As you might expect, this paper is of monumental historical ...

The mystery of dark matter—unseen, pervasive, and essential in standard cosmology—has loomed over physics for decades. In new research, I explore a different possibility: Rather than postulating new ...

It sounds like the setup for a joke: If radio waves give you radar and sound gives you sonar, what do gravitational waves get you? The answer might be “GRADAR” — gravitational wave “radar” — a ...

Potential energy is stored energy. Potential energy is the energy that exists by virtue of the relative positions (configurations) of the objects within a physical system. This form of energy has the ...
