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 ...

A research group from the Technion-Israel Institute of Technology reports in Nature an unprecedented achievement in electron microscopy: the direct measurement of "dark points" within light waves. By ...

Imagine you’re in a car driving across the country watching the landscape. A tree in the distance gets closer to your car, passes right by you, then moves off again in the distance behind you. Of ...

This jet streaming out of a supermassive black hole is traveling at nearly the speed of light. Credit: NASA / JPL-Caltech illustration Superman may fly faster than a speeding bullet, but he'd easily ...

Sadly, a disc could never approach the speed of light. If you had a high-strength steel disc that was 1-metre thick and 1 kilometre in diameter, it would come apart from centrifugal force at just 11 ...

The reliable manipulation of the speed at which light travels through objects could have valuable implications for the development of various advanced technologies, including high-speed communication ...
