University of Adelaide applied mathematicians have extended Einstein’s theory of special relativity to work beyond the speed of light. Einstein’s theory holds that nothing could move faster than the ...

Albert Einstein postulated in his 1905 theory of special relativity that the speed of light in a vacuum is constant. Ever since, that’s been one of the fundamental assumptions of physics. Now Enbang ...

Albert Einstein, one of the most celebrated modern scientists, proposed the revolutionary theory of special relativity more than a century ago. This theory forms the basis of most of what we ...

The theory of special relativity is rife with counterintuitive and surprising effects, the most famous of which are length contraction and time dilation. If an object travels at a relative speed, ...

A humble elevator shaft was recently used in a test of the constancy of the speed of light. Credit: Jason Wong/Flickr, CC ...

The hypothetical faster-than-light particle known as the tachyon may marry with the special theory of relativity, according to a team of physicists, making its existence more plausible. Tachyons are a ...

There is a parlor game physics students play: Who was the greater genius? Galileo or Kepler? (Galileo.) Maxwell or Bohr?

Learn how ocean-surface echoes reshape whale calls and why a similar effect in light would not violate Einstein’s theory of special relativity. When oceanographer John Spiesberger’s whale-tracking ...

Osaka, Japan – Albert Einstein, one of the most celebrated modern scientists, proposed the revolutionary theory of special relativity over a century ago. This theory forms the basis of most of what we ...
