I lost the tweet, but I saw some dipshit mook on Twitter arguing that long-term space travel was “impossible” because of bone density loss that occurs in zero g.

This is the dumbassest argument in the history of arguments because I personally could figure out the math and engineering of tethering two masses together with high-tensile strength kevlar cords and spinning them up to produce one g — and I am fucking terrible at math. This isn’t even hard. We just haven’t done it because we have no reason to yet.

This is same clown in 1650 who would be telling you it wouldn’t ever be possible to navigate accurately because no known technology could produce a clock good enough to measure longitude precisely.

What’s particularly delightful about bozos like that is they say things are “impossible” that we already know how to do. It’s like saying that we’ll never have wireless phones now or something. It’s just incomprehensible.
