Gravitational distortions produced by distant galaxies show a slight—but notable—disagreement with Einstein's predictions.

Why is the expansion of our universe accelerating? Twenty-five years after its discovery, this phenomenon remains one of the ...

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 ...

By closely analyzing the warping of light from distant galaxies, the researchers found a subtle but perplexing discrepancy ...

Here’s how it works. General relativity is physicist Albert Einstein's understanding of how gravity affects the fabric of space-time. The theory, which Einstein published in 1915, expanded the ...

Many of us can point to a teacher who directed our talents toward a career, a fulfilling hobby, a better way to understand ourselves.

Albert Einstein’s “twin paradox” is a famous counterintuitive implication of the special theory of relativity, but it also reveals deep links between physics and philosophy, as Robert P Crease ...

And those questions don’t let up when it comes to reality, or realism. We know that a quantum particle doesn’t have a true ...

A two-day international conference commemorating the hundred years of Bose-Einstein statistics was curiously labelled as "A ...

Known as Bell's Theorem, this groundbreaking idea challenged established physics principles. Decades earlier, Albert Einstein had demonstrated that no information could travel faster than the ...
