US EditionEinstein’s Relativity Predicted a Twisted Illusion – Now Scientists Have Finally Seen It
- A team led by Peter Schattschneider from USTEM at TU Wien demonstrated the Terrell-Penrose effect for the first time using a high-speed precision camera.
- This effect shows that an object moving close to the speed of light appears warped, as if rotated, to an observer.
- The experiment involved moving a cube and a sphere while recording laser flashes reflected from different points on these objects.
- The cube, after taking off, appeared 2.3 times shorter than before, illustrating the warping effect.

A spaceship moving near the speed of light would appear rotated, special relativity experiment proves
Using laser pulses, picosecond exposures on high-speed cameras, and some clever methods to simulate the speed of light, Austrian-based researchers were able to show that the image of an object moving at the speed of light is rotated.
A snapshot of relativistic motion: visualizing the Terrell-Penrose effect
In 1959, Roger Penrose and James Terrell independently predicted that the Lorentz contraction of fast moving objects is not visible in a snapshot photograph. Rather, the object would appear rotated. This surprising effect has never been tested experimentally. Here we demonstrate the Terrell-Penrose effect in a laboratory setting. Using ps-laser pulses and ultra-fast photography with gating times as short as 300 ps, we achieve a virtual reduction…
Einstein’s Relativity Predicted a Twisted Illusion – Now Scientists Have Finally Seen It
Physicists in Vienna have recreated a bizarre visual illusion from Einstein’s relativity—the Terrell-Penrose effect—by simulating slow light speeds with lasers and cameras. A fast-moving cube appears twisted, as predicted over 60 years ago. Relativity Gets Weird at Light-Speed When things move really, really fast, close to the speed of light, our everyday ideas about space [...]
Strange 'Terrell-Penrose Effect' Observed in Lab For the First Time, in New Confirmation of Einstein’s Special Relativity
For the first time, physicists have demonstrated a phenomenon known as the Terrell-Penrose effect, which causes an object moving close to the speed of light to warp before our eyes. The new findings, a collaboration between TU Wien and the University of Vienna, once again confirm a key prediction of Einstein’s theory of relativity by making an optical illusion of relativistic motion observable for the first time. Terrell-Penrose Effect According…
