This new propulsion system could rewrite the rules of spaceflight—not to mention completely defy conventional physics.

Gravity used to be the most down-to-earth of ideas, the thing that kept apples falling and planets in line. Now a growing ...

Is the universe thinking and learning on some level? This is a thorny subject, but one that some researchers are willing to consider. According to research that was published in the pre-print server ...

The dominant view in physics is simple: the laws of nature are fixed. Gravity pulls as it always has; quantum probabilities collapse with the same stubborn indifference today as billions of years ago.

George Musser’s new book finds resonances between the science of the latest wonder materials and string theory, quantum gravity, and the origins of space and time A new short volume by veteran science ...

A pair of theoretical physicists are reporting that the same observations inspiring the hunt for a ninth planet might instead be evidence within the solar system of a modified law of gravity ...

A team of physicists just snared $3 million for testing the law of gravity like never before. Eric Adelberger, Jens Gundlach and Blayne Heckel won the 2021 Breakthrough Prize in Fundamental Physics ...

Gravity is the weakest of the fundamental forces, but it’s the only force that operates over very long distances. Hence, planets orbit stars, stars form galaxies, and galaxies cluster. Gravity also ...

Juri Smirnov receives funding from Danish National Research Foundation. Scientists have been searching for “dark matter” – an unknown and invisible substance thought to make up the vast majority of ...

Scientists have been searching for "dark matter"—an unknown and invisible substance thought to make up the vast majority of matter in the universe—for nearly a century. The reason for this persistence ...
