Why Space Colonization Is a Dangerous Illusion | Michio Kaku

Описание: Why do so many people believe humanity’s future lies on another planet? This video challenges that idea with science, realism, and hard truths. Space colonization is often presented as humanity’s ultimate escape plan—but what if that belief itself is the real danger? In this deep, thought-provoking talk, we explore why space is far more hostile than hopeful, why Earth is irreplaceable, and how the dream of a “backup planet” can weaken our responsibility toward the only world that already sustains us. This video is not anti-science or anti-exploration. It is a wake-up call to understand the limits of technology, the reality of physics, and the urgency of protecting Earth. By the end, you’ll see space exploration not as an escape route, but as a mirror reflecting how rare and fragile life truly is.

What you will learn from this video:
You will learn why space colonization is far more dangerous and unrealistic than it appears, how physics and biology limit human survival beyond Earth, why the idea of a backup planet can be harmful, how space exploration actually helps protect Earth, and why humanity’s long-term survival depends on wisdom, responsibility, and caring for the planet we already have.
