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 ...

Scientists shed new light on mystery origin of ultra-high-energy cosmic ray hotspot

Among many particles arriving from outer space, there are ones with the extremely high energy that travel at nearly the speed of light, which is equivalent of a baseball thrown at a speed of 100 meters per second. New hypothesis for origin of those ultra-high-energy particles has been proposed, thus drawing particular attention from all over the world.
