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 telescope gets upgrade at Brookhaven lab

A radio telescope at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory has received a significant upgrade, advancing from one dish to four. The upgrades are part of the Laboratory's ongoing effort to test the merits of a radio telescope for a potential future project between national labs and DOE-sponsored universities. The scientists' ultimate goal is to look deep into the universe and gain a better understanding of periods of accelerated expansion and the nature of dark energy.
