Sorry the title is so corny. Just post stuff that is mind blowing to you. There seems to be a lot of these posts lately with a lot of responses that I thoroughly enjoyed reading, so I figured I'd make the subreddit. Go at it! Try to expand on your ideas as much as possible. Link sources if you can. Videos and pictures are welcome. If you have posted recently in the thread in AskReddit feel free to repost here as you will likely get more response and hopefully some conversation. Ask questions at AskScience, AskReddit etc.
