Why Humans Will NEVER Leave the Solar System | Leonard Susskind

Humanity dreams of traveling to distant stars. But modern physics may have something uncomfortable to say about that dream. In this video, we explore why escaping the Solar System may be fundamentally impossible — not because of technology, but because of physics itself. The speed of light is not just a technical limitation. It is a hard boundary built into the structure of reality. No object with mass can reach it. No engine can bypass it. Even if we mastered nuclear propulsion, antimatter drives, or hypothetical future technologies, interstellar distances remain brutal. The nearest star system is over four light-years away. That means even light — the fastest thing in the universe — takes years to arrive. And that is only the beginning. The expansion of space, energy requirements, relativistic time dilation, and radiation exposure turn interstellar travel into more than an engineering problem. They turn it into a physical wall. Leonard Susskind has often emphasized that the laws of physics are not suggestions — they are structural constraints on reality. The universe may be vast and beautiful. But it may also be unreachable. Leaving Earth is possible. Leaving the Solar System may not be.
