In this video I show you a top that "never" stops spinning. I talk about conservation of angular momentum and how this top can continue to spin.

Explore the story of our solar system’s formation, tracing how a vast cloud of gas and dust collapsed under gravity, collisions, and angular momentum to create a thin, spinning protolanetary disc.

A massive star 2.5 million light-years away simply vanished — and astronomers now know why. Instead of exploding in a supernova, it quietly collapsed into a black hole, shedding its outer layers in a ...

For at least a decade, the quadruple axel jump was figure skating’s white whale. “It’s been this unreachable thing, like the ...

During the 2026 Winter Olympics, athletes will leap off ramps, slide across ice and spin through the air. These performances will look different to my students who have studied physics through sports.

The registrations for NEET 2026 have commenced. In order to appear for the MBBS entrance test, the candidates need to be well aware of the syllabus for the test. The National ...

Astronomers have watched a dying star fail to explode as a supernova, instead collapsing into a black hole. The remarkable sighting is the most complete observational record ever made of a star's ...

Rare earth elements are essential for modern technology, but their similar chemistry makes separation difficult and expensive ...

Ilia Malinin is not like most figure skaters. Even when he makes mistakes, he is still so far ahead of the rest that he wins Olympic gold.

"Exploring the Sun's Alfvén Surface in the era of Parker Solar Probe" by Sam Badman, Center for Astrophysics | Harvard & Smithsonian (CfA). Abstract: The geometry of a star's Alfvén surface determines ...
