Why the Closest Exoplanet May Still Be Too Far for Humans
Four point two light-years away, a rocky planet circles a dim red star. We call it Proxima Centauri b. It might have water. It might have air. And our fastest spacecraft, screaming through the void right now, would still need over seventy thousand years to get there.
Tonight you board the mission. We will face fuel that doesn't exist, sails torn by single grains of dust, crews that age while Earth forgets them, and a star that flares hot enough to sterilize its own neighbor.
If you want the real numbers behind interstellar travel, hit subscribe and stay with us.
Strap in. We launch now.
