Mars and Earth - Small difference & big consequences

Einstein's theory of relativity suggests that time is not a constant and can vary based on gravitational fields and speed. In a strong gravitational field, time moves slower compared to a weaker one. Since Mars has a weaker gravitational field than Earth, time actually flows slightly faster there.  This concept has implications for future space missions, as the timing of communication and operation of spacecraft will need to account for this difference in how time elapses on Mars compared to Earth. Missions may need to adjust their schedules, operations, and technology to ensure accuracy and synchronization with Earth. Basically, the moment you bring gravity and velocity into the picture, time stops behaving like the simple, universal tick‑tock we experience in everyday life. And you’re absolutely right: Mars’ weaker gravity means clocks there run a little faster than clocks on Earth. What’s fascinating is how small the difference is—and how big the consequences become ...

Future detectors to detect millions of black holes and the evolution of the universe

Gravitational-wave astronomy provides a unique new way to study the expansion history of the Universe. On 17 August 2017, the LIGO and Virgo collaborations first detected gravitational waves from a pair of neutron stairs merging. The gravitational wave signal was accompanied by a range of counterparts identified with electromagnetic telescopes.
