Why Our Nearest Star May Already Be Too Far for Humans

In the cold dark beyond our solar system, a tiny red star burns just over four light-years away, and reaching it would still take longer than human civilization has existed. You think space is close. You are wrong. Proxima Centauri is our nearest stellar neighbor, yet every machine we have ever built falls short of crossing the gap. From the violent flares that may have sterilized its only known planet, to the propulsion limits that turn forty years into forty thousand, this is the honest story of why "nearest" may already mean "never."
