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 ...

Artificial intelligence tool developed to predict the structure of the universe

Advancements in telescopes have enabled researchers to study the universe with greater detail, and to establish a standard cosmological model that explains various observational facts simultaneously. But there are many things researchers still do not understand. Remarkably, the majority of the universe is made up of dark matter and dark energy of an unknown nature. A promising avenue to solving these mysteries is studying the structure of the universe. The universe is made up of filaments where galaxies cluster together. These filaments resemble threads from far away, surrounding voids where there appears to be nothing. The discovery of the cosmic microwave background has given researchers a snapshot of what the universe looked like close to its beginning; understanding how its structure evolved to what it is today would reveal valuable characteristics about dark matter and dark energy.
