Frankie "Five Angels" Pentangili, when he torpedoed his own testimony as witness for the prosecution in Godfather 2: "They said Iceball Earth this, Iceball Earth that, and I said yeah, sure, why not..."
Earth's diameter is about 12,700km. This looks roughly 30 times that, so we'll say 380,000km across, or a circumference of about 1,200,000km (compared to earth's measly ~40,000km).
This puts the overall size somewhere between Jupiter and the sun (probably closer to the sun).
In terms of volume, you could fit about 10,000 standard earths inside the hollow ice ball.
Those people can eat dicks. if you're dumb enough to believe things lime that from random pictures on the internet in places like Lemmy, then the social cost of keeping them 'safe' from this info is greater than the social cost of just letting those troglodytes breed themselves distinct enough as to be out of our gene pool.
I would counter that it’s this kind of hubris that allow these stupid people to gain footholds in our basic institutions. Take a look at anti-vaxxers, flat-earthers, American republicans; to name a few. Misinformation, regardless of intent and/or “obviousness”, is still misinformation. As for our gene pool, it’s rife with bad actors and ill-informed “troglodytes”. In other words, they aren’t going anywhere anytime soon.
