Photons, for centuries both a puzzle and a tool, continue to help scientists illuminate nature at the smallest and largest scales. Photons, the fundamental particles of the electromagnetic field that ...

Something is out there. As far as scientists know, just 15% of the matter in the universe is the ordinary kind we can see.

A large and unexpected excess of top quark pairs has the physics community excited, but the interpretation is still up for debate. In 1995, Alexander Grohsjean cut out a story from the local German ...

Documenting the work of building the world’s largest neutrino experiment presents photographers with a unique set of challenges. Discussing her decades-spanning career, photographer Annie Leibovitz ...

Researchers used the Dark Energy Spectroscopic Instrument to map how nearly 6 million galaxies cluster across 11 billion years of cosmic history. Gravity has shaped our cosmos. Its attractive ...

The Planck scale sets the universe’s minimum limit, beyond which the laws of physics break. In the late 1890s, physicist Max Planck proposed a set of units to simplify the expression of physics laws.

Physics may seem like its own world, but different sectors using machine learning are all part of the same universe. In 2017, Savannah Thais attended the NeurIPS machine-learning conference in Long ...

A professor at the University of Tennessee reimagines the way we teach STEM with a science-fiction story-based class. In the beginning, a spaceship called the Yggdrasil is sailing through the cosmos ...

Electromagnetism and the weak nuclear force are two distinct fundamental forces. That wasn’t always the case. How many fundamental forces are there in our universe? For particle physicists, answering ...

In the 1900s, Albert Einstein unified the concepts of space and time, giving us a useful new way to picture the universe. At the start of the 20th century, physicists had a problem: The speed of light ...

Scientists are championing a relatively new technique as a method to understand the structure of the early universe in three dimensions. With enough time and magnifying power, a telescope can gather ...
