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 ...

Another consequence of the speed of light being fixed is that length must also change. At very high speeds, again within 10 per cent of the speed of light, the length of a moving object seen by a ...

If the speed of light is to be the same for all observers, then the length of a meter stick, or the rate of a ticking clock, depends on who measures it. Ch Frame Code Title 1 A Opening Sequence 2 ...

The contraction of a measured length of an object or a distance in a frame of reference moving at nearly the speed of light, predicted by the theory of special relativity.

Rahul Mandal, the researcher who won TV’s Great British Bake Off last year, is the star of the August 2019 issue of Physics World magazine with a tasty look at the science of baking. Based at the ...
