... Oumuamua doesn't have an unnatural shape, but is consistent with other bodies in our solar system.
You keep making this point. Can you show us any evidence of natural objects from our solar system with a 5 to 1 or larger aspect ratio?
Thus, my point, that the light curve of this body is far from convincing if intended to send the message "I am artificial".
convince the "scientific establishment"? If the thing were perfectly smooth, perfectly cylindrical and flashing a sign that read (in Ancient) "I am an alien artefact. No, really, I really, really AM!
" wouldn't you still be looking to hedge your bets, cover your tenure and protect your reputations by claiming that all of those are reproducible by bioluminecscent bacteria reflecting off of swamp gas in a trillion-to-one freakily accidental but barely possible way?
Not that I imagine it's true but wouldn't it be a neat idea were the "Wow!" signal
a call home handshake from the first
of these probes? A signal that the Earth just happened to dip into the cone of for a few beats before moving away from it.
I wonder how much evidence, apart from "a huge, great lot" would make that conjecture "convincing"? More than we will ever get from the poor efforts at SETI we are currently doing, I expect.
