as much as i like to put on like i’m really clever or educated or something, it’s really as much as
1) being suspicious (something is a little too good to be true)
2) putting that thing into google and looking for snopes/scientific queries about it.
which is literally what i did with that “meteorite” post. i mean, metal screws? Looking at it you might think “those don’t look like metal” or “where’s the nut end they’re talking about?” or “that looks like rebar to me”. Or, okay, that’s my process of thinking, considering I am not a geologist and I couldn’t tell you much about space rocks. (Just fake ones. coughcoughtesseractium) But, I mean. Evidence of alien machinery or ancient earth machinery that got lobbed into space and came back? That should be on the news, if it were legit. We should have heard about it, right?
To google it goes.
Turns out it was on the snopes forum, there’s a link to a fossil forum with one of the pictures and links to other pages/fossil forums explaining it’s probably a crinoid stem. Aha! One of those pages is the source, likely, of the second photo in the post. Putting “crinoid stem” in google shows many similar specimens, enough to deduce that the first photo is also much more likely a fossil than a metal alien work of industry.
All in about 3 minutes worth of google. Et voila, instant academic pretentiousness.
