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 ...

About Fast Radio Burst (frb)

One recent discovery in astronomy is the detection of a repeating fast radio burst (FRB) from a magnetar located in our Milky Way galaxy. This FRB, named FRB 200428, was the first of its kind to be detected within our own galaxy, and it provided astronomers with valuable insights into the mysterious origins of these powerful bursts of radio waves.

 The discovery of a repeating FRB in the Milky Way opens up new avenues for studying these enigmatic phenomena and understanding the extreme astrophysical processes that give rise to them.
