We’ve all had that moment where someone says something that makes you stop and think. Not necessarily a fact or anything, although it could be, but more like an idea, or a concept. It’s that aha moment where you realize something completely obvious but you never really thought about it before in that exact way. For example, did you know that you will be the last person to die in your lifetime? Or how about that for a very brief moment, you were the youngest person in the world out of more than 7 billion people? Those are seemingly obvious things but when you phrase them so succinctly they take on a new form in our brains and really make us think. Of course, not everything on this list is a purely abstract concept. There are a few mind boggling facts that will potentially make you rethink how you see the world or the universe. And then there are some painfully obvious things that you may just never have considered. Did you know that there is a planet in our solar system entirely inhabited by robots? There are 7 of them on Mars. These are 25 concepts and facts that will mess with your head!
