Why Reaching Pluto or Proxima Centauri Is Still Impossible | Space Documentary In this Space Documentary, we uncover the real reason humanity still can’t reach Pluto or Proxima Centauri, despite landing on the Moon and touching the edge of the Solar System. The limits of physics, energy, and time make these journeys nearly impossible — reaching Pluto would take thousands of years, and Proxima Centauri even longer. This Space Documentary explores whether future technology could break these barriers. Join a Space Documentary journey into the challenges that keep our most distant dreams just out of reach.
