Gravity is a force we experience every day, yet it challenges our basic understanding of how the universe works. Why does everything seem to attract everything else? Why do objects fall, and why do ...

Scientists propose using quantum-entangled clocks to test how gravity affects quantum mechanics in curved spacetime.

Less than a decade since the first detection of gravitational waves—ripples in spacetime itself—proposed budget cuts threaten ...

Astronaut Shubhanshu Shukla led a zero-gravity experiment aboard the ISS during the Axiom-4 mission, exploring the behavior ...

Why are black holes so important for quantum gravity? Black holes are the only known objects where relativistic and quantum effects simultaneously become dominant. They offer a unique testing ground ...

The bold question-askers at What If reveal the science behind a gravity-defying substance that’s worth more than gold.

During the Axiom-4 mission, a toy swan named Joy served as the zero-gravity indicator, selected due to astronaut Shubhanshu Shukla's son's affection for animals. This tradition, started by Yuri ...
