Can humanity ever travel to another star system? Science fiction says yes. Physics says… it’s not that simple. In this video, we break down the real scientific barriers that make interstellar travel extraordinarily difficult — and possibly impossible. Using clear, logical explanations inspired by the teaching style of Richard Feynman, we explore the hard limits imposed by relativity, energy requirements, propulsion systems, and the speed of light. You’ll discover: • Why nothing with mass can reach light speed • How Einstein’s relativity creates extreme time and energy challenges • Why the rocket equation makes long-distance missions nearly unmanageable • The deadly impact of interstellar dust at relativistic speeds • Radiation dangers in deep space • The harsh reality of generation ships and human lifespan limits Even reaching the nearest star would demand staggering amounts of energy, advanced shielding, and centuries of travel time. This isn’t pessimism — it’s physics. Watch until the end and decide: Are we destined to remain in our Solar System… or will future breakthroughs change everything?
