This is sort of a follow up one one of my previous threads about something I like to think about when I am bored. So I was wondering what you yall think about that is mind-blowing or something that when you think about it you say to yourself "If I think about this too much longer I might just go insane or my brain might start bleeding" For example: The forth dimension
So post your thoughts and if you want to see mine refer to the thread "Why did I do That?"
