This is what industry does though. That is in the less theoretical fields. If you actually want to make something that works, then you need to base your science on provable fact. Produce oil, build a cool structure, generate electricity. Based on amazing and complex science, but it has to work. Conclusion is that the science that is done needs to be provable, but that means practical. Which is unfortunate. Because what about all that science that may be, or one day may be, practical?
