That moment when your physics calculations hit the cosmic speed limit! The equation v = 2c suggests velocity is twice the speed of light, which is basically telling Einstein to hold your beaker. Nothing can travel faster than light (299,792,458 m/s), so this equation is the mathematical equivalent of dividing by zero—reality.exe has stopped working! Your face would definitely shift from smug confidence to existential panic when you realize you've just broken the universe's most fundamental traffic law. Physics police are on their way!
