Here's a thought experiment for you. Let's say you are driving on a road that crosses railroad tracks. A train is coming. You're feeling confident that you can beat the train to the crossing. If you speed up enough, you win, but if too little, you lose. Velocity is, of course, distance traveled per unit of time in a particular direction. Is this a good time to assert that time doesn't exist, and therefore, speeding up is meaningless? If time doesn't exist, are you even moving? Is the train even moving, or are you just imagining it? But the cleanup crew will be absolutely sure that both the car and train had velocity. And the timing was terrible.

Predicting the weather is hard. But with more data and computing power becoming available, artificial intelligence may be able to help.
