Oh, the classic time travel paradox strikes again! This is what happens when you skip the fine print in "Temporal Physics for Dummies." You disappear from the timeline the moment you step into your DIY time machine, creating the ultimate cosmic joke—you're literally ghosting yourself across decades. Einstein would be rolling in his grave... or maybe he's actually laughing from some alternate timeline where physicists have a better sense of humor. Next time, maybe leave a note: "Gone time traveling, might delete my entire existence accidentally."
