Tachyons Memes

Physics has this fun little rule that nothing can travel faster than light. But what if you did? According to Einstein's relativity, you'd need imaginary mass (yes, that's actually a mathematical concept involving the square root of negative numbers)! You'd become a hypothetical particle called a tachyon that would literally break causality, potentially travel backward in time, and probably violate every law of physics we know. The universe basically says "nope, you're not allowed" and would likely erase you from existence. Breaking the cosmic speed limit comes with consequences way worse than a ticket!
