The LIGO/VIRGO/KAGRA collaboration searches the universe for gravitational waves produced by the mergers of black holes and neutron stars. It has now announced the detection of a signal indicating a ...

Scientists using a global array of radio telescopes have detected the universe’s lowest-mass dark object by observing how it warped light through gravitational lensing. The invisible mass, about a ...

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.

"This is a structure we've never seen before, so it could be a new class of dark object." ...

Gravity is a ubiquitous part of our daily lives — whether we’re being tragically brought to our knees after tripping on the rug or gleefully jumping from a swing’s apex. But despite how common the ...

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 ...

In early July, astronomers spotted a mysterious object, later dubbed 3I/ATLAS after it was confirmed to be the third-ever interstellar visitor cruising through our solar system. Last week, the object, ...

The first detection of gravitational waves in 2016 provided decisive confirmation of Einstein’s general theory of relativity. But another astounding prediction remains unconfirmed: According to ...
