President Donald Trump says he has signed an executive order that seeks to speed up reconstruction of tens of thousands of ...

At The Speed Of Light Time Stops… This video explores the fascinating phenomenon of time perception and its relation to speed. Viewers will gain insight into how high velocities impact our experience ...

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still daring to test it. Some theories of quantum gravity suggest light might ...

Covariant reformulation of relativity with dynamic time as a field and emergent light speed. Proposes two-metric geometry (gravitational + causal), synchronization holonomy as key observable, and ...

Speed limits across Texas roads are about to get smarter. In an effort to make highways safer and more responsive to real-time conditions, state officials are beginning a wider rollout of variable ...

Researchers at Tsinghua University developed the Optical Feature Extraction Engine (OFE2), an optical engine that processes data at 12.5 GHz using light rather than electricity. Its integrated ...

An example of what variable speed limit signs look like above a highway in Washington. Courtesy of the Washington State Department of Transportation When icy conditions led to a 133-car pileup on ...

Texas drivers, prepare to go with the flow—literally. New variable speed signs are popping up across the state, changing speed limits in real time to keep traffic moving and accidents at bay.

A gamma-ray burst (GRB) — the most energetic type of explosion in the universe since the Big Bang — is detected once every day, on average. But what happened on July 2, 2025, was highly unusual: ...
