Famed physicist Albert Einstein at the blackboard. Albert Einstein's theory of special relativity revolutionized science and, once proven observationally, brought the physicist international fame.

The idea that objects contract in length when they travel near the speed of light is a widely accepted consequence of Einstein’s special relativity. But if you could observe such an object, it ...

The Terrell-Penrose effect, predicted in 1959, suggests that objects moving at speeds close to that of light appear rotated. This optical illusion results from the combination of relativistic length ...

When an object moves extremely fast—close to the speed of light—certain basic assumptions that we take for granted no longer apply. This is the central consequence of Albert Einstein's special theory ...

relativity established by theoretical physicist Albert Einstein is an important theory that is the basis of modern physics, but there is also an image that it is related to complicated phenomena such ...

The Ladder Paradox is a famous thought experiment that shows you why you can fit objects into spaces that are too small for them. And also why you can’t, depending on your perspective. Relativity does ...

Ronald C. Lasky, a lecturer at Dartmouth College's Thayer School of Engineering, explains. Time must never be thought of as pre-existing in any sense; it is a manufactured quantity.--Hermann Bondi ...

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.
