Anything that works in practice can work in theory.
When a theory tells us something that is working is impossible, we’ve either measured wrong or the theory needs updating.
Theories exist to explain, predict and understand. They are supposed to help us see and improve the world around us, and they’re never finished, just ever better explanations seeking to catch up with reality.
If a theory is effective, use it.
When it’s not, don’t blame reality.
