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 ...

Radio burst inside Milky Way may give clues about fast radio bursts

Radio observatories around the world have reported capturing a unique event—a strong, millisecond-long burst of radio waves coming from a type of neutron star inside the Milky Way. Because of its strength, space scientists are hoping that further study will show that it was a fast radio burst (FRB) emanating from within our own galaxy—if so, a great mystery might soon be solved—their source.
