The Great Filter May Explain Why Civilizations Don’t Survive

Описание: The universe is old enough, large enough, and chemically rich enough to have produced countless civilizations. And yet, when we listen, we hear nothing. The Great Filter hypothesis offers one of the most disturbing explanations in modern science - somewhere between dead chemistry and starfaring intelligence, there exists a barrier so severe that almost nothing gets through. But the real question isn't whether the filter exists. It's whether we've already passed it - or whether it's still ahead of us, waiting. This video explores the formal probability argument behind the silence, the candidate barriers hiding in the deep history of biology, the existential threats that scale with technological power, and what every new discovery about life beyond Earth actually tells us about our own survival odds.
