An experiment has visualized a prediction about objects traveling at the speed of light known as the Terrell-Penrose effect, first made over 60 years ago. When an object approaches the speed of light ...

In 1959, physicists James Terrell and Roger Penrose (Nobel laureate in 2020) independently concluded that fast-moving objects should appear rotated. However, this effect has never been demonstrated.

The Sagnac effect, first observed over a century ago, remains central to our understanding of relativistic kinematics and the operational definitions of simultaneity. Fundamentally, this effect arises ...

In late 2020, physicist Harold “Sonny” White, PhD, research director of the nonprofit Limitless Space Institute, noticed something peculiar—and familiar—in a circular pattern of data plots generated ...

Imagine traveling at the speed of light and still being too slow to escape the vastness of space. From the nearest star Proxima Centauri to the Milky Way’s edge, this journey reveals the mind-boggling ...

So, you’re driving a car at half the speed of light. (Both hands on the wheel, please.) You turn on the headlights. How fast would you see this light traveling? What about a person standing by the ...

Researchers have found a way to mimic lightspeed when photographing an object. The method involves stitching together many thin “slices” of light reflecting off the object. Photography—itself a ...
