Galaxy Simulations Offer a New Solution to the Fermi Paradox

There are significantly fewer planets that have gas giants around compared to the ones that don't. It it certain that gas giants prevent debris attacking small rocky planets.

I don't think we know the former and we kind of sort of maybe know the latter for the Solar system right now. As to the rest, I don't follow the relevance, we're not talking about searching for intelligent life at all.

Do you think we're searching for unicellular life then? We're doing our best to search for intelligent life. That means looking for what we know to be able to support life and to eliminate other random searches. Occam's razor and all that. What else are we talking about?

You're right about the former not being certain, but it's definitely rare amongst the planets we've found? And the latter is quite certain.

'planets we've found' is a huge sampling bias because of our current methods. We can't even look for Jupiters, it's unsurprising they are 'rare'.

What else are we talking about?

I mean this thread was not about how we search for life. It's about an estimate of the prevalence of intelligent life - an 'explanation' for the Fermi paradox. I'm saying it's basically a story.
