The subreddit interestingasfuck (sorry Mom) is, for my money, one of the best. The content is a curated mix of interesting photos, charts, pics, and video clips featuring cool stuff you either regularly take for granted (like brick paths and the moon) or didn't know existed (like oxidation on the surface of Bismuth). This photo gallery includes pictures of natural phenomena, manmade things, the goings-on inside our own bodies, and tons of other cool sh*t that might even teach you a thing or two. The universe is pretty amazing. Let's look at it together!
