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 ...

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.

Scientists have used theloudest gravitational wave signal ever recorded to put Albert Einstein’s century-old theory of ...

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 ...

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 ...

In the UK, falls in hospital are the most commonly reported patient safety incident. Risk is multifactorial and increases with age, some medications, and conditions such as delirium and dementia.

Banner image: A pulsar ejecting a plume of energy. (Credit: NASA/HST/ASU/J. Hester et al.) Scientists have used a “galaxy-sized” space observatory to find possible hints of a unique signal from ...

The Work Energy Principle is one of the big ideas in introductory physics courses. It's so big that the textbook presentation can get a little confusing - but it doesn't have to be that way. I haven't ...

Decades ago physicists realized that gravitational waves are no mere passing phenomenon. Instead those ripples in space should leave behind permanent marks: a fixed distortion in their wake. So far ...
