"Time Dilation: The Communication Challenge for Interstellar Astronauts"

Interstellar travel presents significant communication challenges due to the finite speed of light and time dilation. Messages sent to spacecraft traveling at near light speed would experience severe time delays, and spacecraft would eventually be cut off from Earth. Different scenarios, such as constant acceleration or deceleration, introduce their own communication challenges, including signal pile-up and limited reception. Interstellar travel would require independent operation and would be a lonely journey.
