The Atacama Cosmology Telescope in Chile has released its final batch of data after 15 years — and it proves that the Hubble ...

The universe is expanding, but astronomers still cannot agree on exactly how fast. That mismatch, known as the Hubble tension ...

New polarization maps from the Atacama Cosmology Telescope align with Planck’s results and confirm the lower early-universe ...

Physicists tested light speed using cosmic gamma-ray bursts. Study confirms Einstein's prediction that all light colors travel at same speed.

Max Planck, a name synonymous with the very beginnings of quantum physics, was a scientist who, while perhaps not seeking a revolution, certainly started one. He’s often called the father of quantum ...

So, you know how sometimes someone just changes everything? Like, they come along and totally flip the script on how we see the world? Well, in physics, that person was Max Planck. A lot of folks call ...

Researchers at the National Institute of Standards and Technology (NIST) have made their most precise determination yet of Planck’s constant. This will let NIST redefine the kilogram, the official ...

I’d like to invite you to an even higher level of nerdom! Every good nerd knows that E=mc^2. Every great nerd knows that, really, E^2=m^2c^4+p^2c^2 Want to know what that even means? Sure, I’ll tell ...

The physicist Max Planck (actually born as Marx Planck) is best known for the development of his universal constant that defines physics at the most basic level. It is an important number, and today ...
