One of the most striking features of quantum physics is that certain properties cannot be measured at the same time. Every measurement may inevitably affect the object's physical state being ...

Ripples in the fabric of space-time called gravitational waves may be the key to solving the Hubble tension — one of the biggest nagging problems in physics.

During the mid- to late-twentieth century, quantum physicists picked apart the unified theory of physics that Einstein’s theory of relativity offered. The physics of the large was governed by gravity, ...

We know how to derive most fundamental constants from conditions of the universe, models This is an accurate description of physics as a whole, but wildly untrue in particle physics. There are 25 ...

We have known for several decades that the universe is expanding. Scientists use multiple techniques to measure the present-day expansion rate of the universe, known as the Hubble constant. These ...

In the last few weeks I've been working on a slightly more formal version of this post on black-body radiation for use in something else. One of the tricky things in writing about the development of ...

The 50-foot-wide racetrack used to study muons traveled by barge around Florida and up the Mississippi, and then by truck across Illinois. Reidar Hahn, Fermilab About 50 years ago, physicists came up ...

Recently in my physics lab, students were having trouble with the difference between mass and weight. I had ready answers---it’s a topic I’ve gone over hundreds of times. But after I explained that ...

The display comprises seven sculptures that are illuminated from two different directions. The result is two very different ...
