Drunken Philosophy: Where Is Everybody? The Fermi Paradox and the Great FilterWelcome to Drunken Philosophy, a casual, curious, social discussion club. Come grab a drink and a seat at The Oracle.
**Optional topic for this meetup: Where is everybody?**
In 1950 the physicist Enrico Fermi was talking about aliens over lunch and asked a question that still has not gone away: if the universe is so vast and so old, and even a fraction of those billions of stars have planets, where is everyone? By the numbers the galaxy should be crowded with civilizations. Instead we look up and hear silence. That gap between "they should be everywhere" and "we see no one" is the Fermi Paradox.
One of the most unsettling answers is the idea of a **Great Filter**: somewhere on the road from dead chemistry to a galaxy-spanning civilization, there is at least one step that is almost impossible to get past. Maybe the filter is behind us. Maybe life starting at all, or simple cells becoming complex, or intelligence ever evolving, is the freak accident, and we already cleared the hard part. Or maybe the filter is ahead of us, and advanced civilizations reliably wipe themselves out before they spread.
Here is the part that messes with people. If we ever found life somewhere else, even pond scum on Mars, most people would call it the greatest discovery in history. But it might be the worst possible news. It would mean life is common, the early steps are easy, and the hard step is still in front of us. So the eerie silence overhead might actually be the best sign we could ask for.
**Questions to wrestle with:**
* Is it better to be alone? Would you rather we find alien life and learn we are not special, or find nothing and quietly improve our odds of surviving?
* Where do you bet the filter sits, behind us or ahead of us, and why?
* If it is ahead of us, what is it? Nuclear war, climate collapse, AI, something we cannot even picture yet? And can we do anything about a filter we cannot see coming?
* Does any of this change how you live, or how humanity should be spending its time and money right now?
As always the prompt is optional. Come for the conversation, stay for the drinks, and bring your own questions.
