Astronomers Detect a Possible Signature of Life on a Distant Planet

This is unsettling. If we are not the only intelligent beings in the universe, it adds credence to the idea of a "great filter."

I think it would be cool if the conversation on this post could go more into detail about hycean planets instead of the pretty standard and played out one about the Fermi Paradox and Great Filters.

That stuff is interesting but I'd rather hear experts talk about less talked about stuff like hycean planets and detection methods of them and other bodies that are that size.

what happens if you have lightning on a hycean planet?
