Gravitational wave astronomy is starting to do more than confirm Einstein’s equations. It is turning into a precision tool ...

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.

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 ...

Prof. Ralf Schützhold at Helmholtz-Zentrum Dresden-Rossendorf (HZDR) has devised an experiment that allows for not only the ...

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 ...

For decades, physicists searched in vain for evidence of gravitational waves, the stretches and squeezes in spacetime that were first predicted by Albert Einstein’s theory of general relativity a ...

Energy is conserved. It cannot be created or destroyed. Energy can be transferred between stores. The total energy has the same value before and after any changes. A diving platform is 10 m above the ...
