How Far Can We Travel Through Space Before We Die?

The fastest object ever built still needs 6,600 years to reach the nearest star. So how far can a human actually travel before they die? We cover the rocket equation that makes chemical engines mathematically useless at interstellar scales, the time dilation loophole hidden in Einstein's relativity that lets one lifetime span thousands of light-years, the galactic cosmic rays silently destroying crew DNA with no shielding solution, dark energy accelerating the universe apart faster every century, the cosmological event horizon — the permanent wall 16 billion light-years out that no technology can ever cross — and exactly how much of the observable universe we can actually reach. The answer will change how you see the night sky. #InterstellarTravel #TimeDilation #DarkEnergy
