How Does Explanations and the Problem of Infinite Regresses Work?

Explanations are like building blocks, each one helps you understand something better, but sometimes they can lead to a never-ending chain of questions.

Imagine you have a toy car that goes vroom-vroom. You ask, “Why does it move?” I say, “Because the wheels spin.” Then you ask, “Why do the wheels spin?” I answer, “Because the motor turns them.” You keep asking, “Why does the motor turn?” and so on. If we never stop asking why, we might end up with an infinite regress, a chain of reasons that goes on forever without ever stopping.

An infinite regress is like trying to count to infinity, you just keep going, and there's no end in sight. It happens when each explanation needs another explanation, and that one needs another, and so on, endlessly.

But sometimes we don’t need to go all the way to the end. If the toy car’s motor turns because of a battery, and the battery works because it has energy, well, maybe you're okay with that for now! You can stop asking why when the answer feels good enough.
