Breaking the Universe’s Speed Limit: The Quest for Faster-Than-Light Communication
Imagine sending a message to a spacecraft light-years away and getting an answer immediately. Faster-than-light information transfer means exactly that – sending data at velocities beyond the ~300,000 km/s speed of light. It’s a sci-fi dream with profound implications. If we could break this cosmic speed limit, it would revolutionize communication across interstellar distances, erasing the multi-minute lag in talking to Mars or the decades-long silence between stars. Beyond convenience, it would upend physics itself. According to Einstein’s theory of relativity, nothing carrying information can outrun light without wreaking havoc on cause and effect theguardian.com. As one science writer put it, if FTL messaging were possible “it would open up the troubling possibility of being able to send information back
