As gravitational wave detectors become more advanced, tracing their principles and history can engage undergraduate students with modern physics.

At Utah State University, researchers are using a radical idea known as the holographic principle to bridge the gap. By crafting precise mathematical models, they’re venturing where experiments can’t ...

It appears that we live on the knife-edge, where only the narrowest combination of values for the fundamental constants allow ...

The discovery in 1998 that the Universe is expanding faster over time shook the foundations of cosmology. This finding ...

This NASA/ESA Hubble Space Telescope image offers us the chance to see a distant galaxy now some 19.5 billion light-years ...

Surprise: You can answer this question with modern algebra.

Einstein’s strangest optical illusion has been captured—thanks to lasers, a cube, and a bit of artistic inspiration.

They found that the Lorentz contraction—a key part of Einstein’s theory of special relativity—doesn’t actually change how a fast object looks in a photograph. Instead, the object seems ...

Austrian physicist Erwin Schrödinger introduced his famous equation, now known as Schrödinger’s Equation. This groundbreaking ...

Using a specific gauge-fixing method, the theory matches the teleparallel equivalent of general relativity (TEGR), which itself is a form of Einstein’s theory that describes gravity using ...
