His theory of special relativity stemmed from his desire to understand the nature of light and what would happen to objects ...

Einstein’s special relativity, which he formulated in his “miracle year” of 1905, was a theory that revolutionised our ideas of space and time – and ultimately paved the way for some even ...

Top quarks follow the rules of special relativity day and night. Is there a time of day or night at which nature's heaviest elementary particle stops obeying Einstein's rules? The answer to that ...

Einstein’s special theory of relativity, published a hundred years ago, also revealed that energy and mass are two sides of the same coin, forever linked in his famed equation E = mc2.

Einstein received the Nobel Prize for one of the other ideas, but the special theory of relativity has since become the most well-known, perhaps of his career or even the entire field of physics!

Scientists propose a relatively simple yet still complicated tabletop experiment to test the quantumness of gravity, aiming to reconcile general relativity and quantum mechanics.

On March 14, 1879, Albert Einstein was born in Ulm, Germany. His thinking revolutionized physics and turned the scientific ...

Here are a few thought experiments that demonstrate some of Einstein's most groundbreaking discoveries, including his special and general theories of relativity. What would happen if you chased a ...

Historically, there have been many ways to track time and account for the changes in daylight hours that come with the ...
