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 reveal photochemical rationale of SH(X)/H2S abundance ratios in interstellar medium

Research group led by Prof. YUAN Kaijun and Prof. YANG Xueming from the Dalian Institue of Chemical Physics (DICP) of the Chinese Academy of Sciences revealed the photochemical rationale of SH(X)/H2S abundance ratios in interstellar medium with the help of Dalian Coherent Light Source. The results were published in Nature Communications.
