“You could always have a go at the internet’s hardest puzzle, Notpron. It’s been online since 2004, but only 67 people ever made it through all 140 levels. I’ve been playing since 2007, and am in the 70s now.”—sedermera

“The Titanic didn’t really sink, instead the Olympic did in an insurance scam. ETA: I don’t actually believe this, it’s just one hell of a theory to read.”—nicknaklmao

“Wikipedia and pick a country and look at the history of their leaders. Can be interesting to see a list of them and the politics behind it especially African countries cause they’re wild how often they switch and for why.”—bobd0l3

“Science channels. From entertaining to informative, science channels have been my favorite types of channels to binge. Vsauce is one of the best at this. Backyard Scientist, Mark Rober, and SloMo Guys to name a few. And if you’re up to a mental challenge, go for really heady, concept, theory-laden channels like PBS SpaceTime and Quantum Gravity Research.”—Classic-Fold

“Learning history is my best way to time pass. Currently, I am diving deep into Pyramids. It’s pretty damn interesting to know how they did that stuff. Imagine lifting 2.3 million blocks each the weight of elephants to that height and that too so many years ago when humans were I would like to share a few things that I learned. Maybe you might like it and go deep into it.”—Shampoo_and_dick

“Try researching the DuPont family. Not the medical field, innovative part, but the fucked up evil incest haunted house parts. It’s hard to find info because billionaires control everything but it’s there.”—missymeliss144

“If you’re into music, there are a ton of great channels on YouTube. Rick Beato does a lot of music and song analyses. Alex ball has done some documentaries about Roland, and the prophet synthesizers. All really interesting history and information. True cuckoo is a dude who has a ton of videos about synthesizers, drum machines and jams. Not to mention tutorials. There’s so much that you can learn. I started with guitar and recently I got into synths and drum machines and YouTube is a great place to get to learn from plenty of talented people. I missed a ton but I guess you can do the exploring yourself.”—gardeniasoutside

“One of my favorite things to do is look around on Google Earth at an area you never plan on traveling too. ZOOM WAY IN. And learn about the small villages/communities/cities that live on completely different continents or tiny islands in the middle of nowhere. It’s seriously insane how humans are willing to live ANYWHERE.”—t4blespoon

“In the early 2000s, someone began posting on several message boards claiming to be a military time traveler from the year 2036. He arrived in 2000on a stopover for personal reasons; his primary mission was to return to 1975 to recover an IBM 5100 computer which was needed to debug huge computer issues that would arise in his original time. Some have disregarded this as an elaborate hoax. The rub is, there is an anticipated y2k style computer frying event (look up UNIX 2038 problem), and only like 5 people in the world knew the IBM 5100 debugging programming existed, which was later confirmed to be true by someone involved with the project. His stories contained predictions from his timeline, time travel theory, physics of his machine, and even schematics of the time travel device. All his posts are archived, enjoy your trip down the rabbit hole!”—Slickdilla
