We’ve all heard about Proxima Centauri—that little red dwarf star just 4.24 light years away, with its tantalizing planets Proxima b, Proxima c, and Proxima d. Ever since 2016, astronomers dreamed of reaching those so-called “Earth-like” exoplanets. But let’s face it: interstellar travel isn’t just about speed or photonic sails or Breakthrough Starshot probes. It’s about survival. Our biological evolution, genetics, and circadian rhythms are tied to Earth’s gravity, magnetic field, and 24-hour cycle. Go beyond the magnetosphere, and it’s not just cosmic radiation hitting you—your DNA starts to change, your bones melt, your brain rewires. Even Scott Kelly showed over 8,000 genetic alterations after 340 days in orbit. Now imagine 42 years to Proxima, and the radiation dose alone is 300x the lethal limit.
The real nightmare? Colonization.
