"Time Dilation: The Communication Challenge for Interstellar Astronauts"

Interstellar travel poses significant communication challenges due to the finite speed of light and time dilation. Messages sent to spacecraft traveling at near light speed would experience significant time delays, potentially leading to communication blackout periods. Clocks are not synchronized across the universe, and travelers on board the spacecraft would experience time passing more slowly than on Earth. Different scenarios, such as constant acceleration or deceleration, would introduce their own set of communication challenges. Interstellar vehicles would need to operate independently, as they would eventually be cut off from Earth, making interstellar travel a lonely journey.
