Understand Einstein’s General Relativity with a clear and easy-to-follow explanation that breaks down complex ideas like ...

For over a century, Einstein's general theory of relativity has been key to understanding gravity. But new research suggests this theory "glitches" in the farthest reaches of space. That doesn't mean ...

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 ...

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 ...

Einstein’s equations were written for chalkboards and paper, yet they now sit at the heart of some of the most visually ...

The faster you move, the stranger time becomes. By imagining how light travels to two people moving at different speeds, Einstein showed that time isn’t absolute. His thought experiment revealed that ...

Einstein's greatest lesson may be that reality is not what it seems; what we perceive as real is a distortion due to how our brains take in the... One hundred years ago, a 36-year-old Albert Einstein ...

To understand gravity, Einstein had to rethink space and time as a single connected fabric. He showed that mass bends this fabric, guiding how everything moves. NOVA is available to stream on pbs.org ...

Dark energy, making up 70% of the universe, causes its accelerating expansion. Gravitational waves, predicted by Einstein, were detected from colliding black holes. The Event Horizon Telescope imaged ...
