Why Physics Makes Interstellar Travel IMPOSSIBLE

The fastest object humanity has ever launched toward interstellar space is crawling toward the edge of our solar system. At its current speed, it would take over 70,000 years to reach the nearest star. But speed isn't the problem. Even with a perfect engine and unlimited funding, the universe itself prevents us from ever reaching the stars. This calming long-form space documentary explains exactly why - and the answer is far more devastating than most people realize. Einstein's special relativity revealed that the speed of light isn't just fast. It's the structural speed limit of reality itself — woven into the geometry of spacetime at a depth no technology can touch. As any object with mass accelerates toward light speed, the energy required follows the Lorentz factor on a curve that bends toward infinity. Not metaphorical infinity. Mathematical infinity. The kind where the equations stop producing answers. Sources: Einstein, A. (1905). "On the Electrodynamics of Moving Bodies."
