China has unveiled the world’s most powerful hypergravity centrifuge, the CHIEF1900. This machine marks a major leap in the ...

China has quietly built a machine that bends one of the most stubborn limits in physics research: gravity itself. By pushing ...

The accelerating expansion of the universe is usually explained by an invisible force known as dark energy. But a new study ...

All fundamental forces operating on astronomical scales exhibit a decrease in strength with increasing distance. A hypothetical force, decreasing with distance slower than the inverse square law, ...

Isaac Newton confessed that he had no idea what gravity was. The 17th century English polymath knew what it did, and he described it with a universal law of gravitation. But where the law came from, ...

Just over a week ago, European physicists announced they had measured the strength of gravity on the smallest scale ever. In a clever tabletop experiment, researchers at Leiden University in the ...

Time has an arrow: It only ever seems to move in one direction. The future is always unknown to us, while the past forever remains locked and inaccessible. And yet, the vast majority of the laws of ...

The power of gravity is writ large across our visible universe. It can be seen in the lock step of moons as they circle planets; in wandering comets pulled off-course by massive stars; and in the ...
