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 ...

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 ...

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 ...

For decades, astronomers have puzzled over dark energy and why it's pushing our universe apart. New data from the largest 3-D map of our universe suggests we may be wrong about dark energy. Dark ...

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 ...

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 ...

One and a half million words was the estimated output of some 3,000 members of the American Association for the Advancement of Science and associated groups who met last week in Pittsburgh. They read ...

Who was Einstein? Why is he still so alive? / Gerald Holton -- A short history of Einstein's paradise beyond the personal / Lorraine Daston -- Einstein's Jewish identity / Hanoch Gutfreund -- Einstein ...

Many astronomers have wondered where the center of the universe is. If the Big Bang created the entire observable universe, then it stands to reason that the event had a point of origin. As it turns ...
