We haven't seen that, okay?

And the dinosaurs, if they launched anything to...

a geosynchronous orbit or even closer, then it would still be around.

And we haven't seen anything.

So that's perhaps... Well, but if there are unidentified anomalous phenomena, they could have been those gadgets that were left behind from a previous civilization that somehow...

had the failure modes that we have.

We engage in conflicts very often, mainly male, alpha males.

And we also often do things that harm us in the long term, but we enjoy it in the short term.

And one example that I recently wrote about is there is a company now that wants to get...

approval from the FCC to put mirrors in the sky.

I've heard about this channeling solar energy to the planet, yes?

Yes, during nighttime.

So basically, each beam of light will illuminate... And it's a huge array of satellites, right?

50,000.

They ask for 50,000 satellites, and each of them will produce a beam of light five kilometers in diameter that can illuminate, for example, a city.

The problem is that we won't be able to observe the universe at night.

The only reason we can learn about the universe is because the Earth blocks sunlight, and that allows astronomers to look from the dark side of the Earth, to look out and see faint sources of light.

That's the only reason we can do astronomy.

Now, this company wants to illuminate the night side with these...

flood lights and the problem is that part of the light will be scattered by clouds so we if i this this could be a new answer to fermi's paradox you know enrico fermi in 1950 asked them where is everybody right uh he was an italian and if i was next to him i i would put my hand around him and say enrico this is a question that every lonely person asks
