Einstein proved space and time are one unified fabric. Astrology may be mapping your exact coordinate within it—your unique entry point into reality. Here’s why that idea is more profound than it ...

The cosmos is a unique laboratory for testing the laws of physics, in particular those of Euler and Einstein. Euler described the movements of celestial objects, while Einstein described the way in ...

Einstein's theory on the expansion of the universe might be wrong. At least, that's the running idea behind a new study published in Classical and Quantum Gravity earlier this month. The study was led ...

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 ...

Everything in the universe has gravity – and feels it too. Yet this most common of all fundamental forces is also the one that presents the biggest challenges to physicists. Albert Einstein’s theory ...

On March 15, 2024, a space-based observatory detected bursts of low-energy X-rays from deep in the ancient universe, fluctuating in brightness for over 17 minutes before fading away. About an hour ...

Why is the expansion of our Universe accelerating? Twenty-five years after its discovery, this phenomenon remains one of the greatest scientific mysteries. Solving it involves testing the fundamental ...

What is the universe made of? This question has driven astronomers for hundreds of years. For the past quarter of a century, scientists have believed “normal” stuff like atoms and molecules that make ...

Research teams on both sides of the Atlantic have shown that precise modeling of the universe and its contents will change the detailed understanding of the evolution of the universe and the growth of ...
