Effect of relative: Scientists create Terral-Penrosis for the first time in the laboratory
Scientists first were able to reproduce the influence of the terel-penrosis at the speed of two meters per second using laser pulses and accurate cameras.

Scientists from Vinna University In the laboratory, they used the technical ‘trick’ to mimic just 2 meters (m/s) light per second, and the first time the effect of the terel-Penrosis created the effect.
When an object moves very fast, some basic UMP hall is no longer applicable.
This is the main consequence of the restricted relative theory of Albert Einstein. The object then has a different length from rest and time goes different than the laboratory. All of this has been repeatedly confirmed by experiences.
Terral-Penrosis
However, however, One Interesting consequences of relative have not yet been observed: so -called The effect of terel-penrosis.
In 1959, physicists James Terrell and Roger Penros (Nobel Prize winner in 2020) concluded independently. However, this effect has never been displayed.
Now, the cooperation between the University of Technical Vienna (Thu Veen) and Vienna University It was originally able to reproduce this effect using laser pulses and accurate cameras, with an European Press Agency on Monday, at an effective light speed of 2 meters per second.
In a statement, Vienna’s Technical University Peter Shatschnider explained in a statement that “let us cross the same length before leaving,” Imagine will be able to cross us at 90% at 90% of a rocket light speed. “
It is also known as Lorenz contraction of the length of the length. However, this contraction cannot be photographed.
“If I want to cross the photograph of the rocket, you should know that the light of different points has taken different times to come home,” said Peter Scotschnider.
The light coming from different parts of the object and the light that reaches the lens or human eye at once, is not released simultaneously, producing complex optical effects.
This feature is absurd in everyday life even when you take a very fast car photo. As well of the car Formula 1 Only a small part of the distance travels from the fastest side and the light emitted from the side of the photographer. But as the rocket travels at speed near light, this effect is evident.
Laser pulses and high -speed cameras to create an impact rebuild
Technically, it is now impossible to speed up the rockets with the speed that can observe this effect in the photograph.
However, a group led by Peter ScotSchnider found a solution that triggered another art: They have used very small laser impulses and high -speed room to re -creating laboratory effect.
“We move a cube and a sphere through the laboratory and use a high -speed room to record the laser lights reflected at different times from different points of these objects,” Victoria Helm and Dominic Hornoff, explained.
If the time is calculated properly, the light speed does not exceed two meters per second, but the same results can be created.
Including what happened for the first time in this experience Time of factors: The object is taken by the photo at most times. If the light speed is only 2 m/s in the same static image, the light will be released from this time of light. This causes the effect of terel-penrosis.
“We combine static images in short video clips of ultra -rear objects. The result is exactly expacted,” said Peter Scotschnider.
“A cube is twisted. A sphere is still a sphere, but the North Pole is in a different place,” he said.
