We break down Einstein's famous twin paradox to illustrate time dilation in special relativity. Discover how acceleration, ...

Time dilation: It’s a staple of science fiction, and whether you’re familiar with the term or not, you’ve probably encountered it in print or film. Fly fast enough to the speed of light, and your ...

Scientists could soon test Einstein's theory of general relativity by measuring the distortion of time. General relativity states that gravity is the result of mass warping the fabric of space and ...

Albert Einstein changed science forever with special and general relativity, redefining space, time, and gravity. Yet after his greatest triumphs, he became obsessed with something even bigger — a ...

Is there a time of day or night at which nature's heaviest elementary particle stops obeying Einstein's rules? The answer to that question, as bizarre as it seems, could tell scientists something very ...
