If the condition in a while loop never becomes false, the loop will run infinitely, meaning it will keep executing the block of code without stopping. This typically happens when the condition doesn't have a terminating case, such as when the increment or change to the variable inside the loop is missing. Infinite loops can cause a program to crash or hang because they consume resources without ending. In programming, infinite loops are often unintentional but can sometimes be used intentionally for server processes or waiting for user input.
