The theory of special relativity explains how space and time are linked for objects that are moving at a consistent speed in a straight line. One of its most famous aspects concerns objects moving at ...

Monisha Ravisetti was a science writer at CNET. She covered climate change, space rockets, mathematical puzzles, dinosaur bones, black holes, supernovas, and sometimes, the drama of philosophical ...

‘I love the idea that this basic principle that Einstein told us about a long time ago is something you can see,’ CU Boulder astrophysicist says Scientists who study the cosmos have a favorite ...

Among the intriguing issues in plasma physics are those surrounding X-ray pulsars -- collapsed stars that orbit around a cosmic companion and beam light at regular intervals, like lighthouses in the ...

An illustration conveying the idea of a space-based quantum internet, which would seem, like the hypothetical particle of a tachyon, to outpace light. An illustration ...

First of all, the prevailing quantum theory, quantum field theory, is fully relativistic from the onset. Relativity is “built into” the theory, so to speak. And it’s the only quantum theory that is ...

Two years ago I pointed out 1 what appears to be an inconsistency in the kinematical part of Einstein's special theory of relativity. I repeated this in a slightly different form in a volume published ...

Albert Einstein’s legendary reputation as history’s greatest theoretical physicist, which National Geographic seeks to mine for humanity in Genius, is due in large part to his theory of relativity — ...

It stands among the most famous theories ever created, but the general theory of relativity did not spring into being with a single, astonishing paper like the special theory of relativity in 1905.

Albert Einstein’s Theory of Relativity is one of the most significant scientific advances of our time. The concept of relativity was not introduced by Einstein, but he was a major contributor with the ...

Like Max Planck, Albert Einstein first studied mathematics because he was told that everything interesting in physics had already been discovered. But in 1905, Einstein, a young cleark at the Swiss ...
