Trying to solve quantum gravity is frustrating. We have made tremendous progress in quantum theory, but it seems that every ...

Gravity is a ubiquitous part of our daily lives — whether we’re being tragically brought to our knees after tripping on the rug or gleefully jumping from a swing’s apex. But despite how common the ...

Light from a distant galaxy becomes warped as it travels through space-time gravitationally curving around a foreground ...

A 10-year effort to measure gravity, a fundamental force in the universe, has failed to come up with a conclusive answer.

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 ...

For decades, the four known forces of nature, gravity, electromagnetism, and the strong and weak nuclear forces, have accounted for every interaction physicists can measure in a laboratory or a ...
