Action at a distance

Action at a distance is when something can make something else happen without anything touching each other. It's like magic! But it's not really magic, it's just science. Some examples of action at a distance are gravity and electricity. In the case of gravity, things can attract each other even if they are very far away from each other. In the case of electricity, electricity can move through wires even if there is a long distance between them. This is all possible because of something called fields. Fields are like invisible blankets that wrap around objects and are able to make things move or be attracted to each other over long distances.
