Part 1/12:
The Challenges of Interstellar Communication
The universe is filled with the promise of advanced civilizations potentially spread across the stars. Yet, if they were to establish galactic empires, a significant challenge would arise: how to maintain effective interstellar communication across the vast distances of space. According to Einstein's theory of relativity, no particle can exceed the speed of light, placing an effective speed limit on communication that can make interactions between distant civilizations seem impractical.
