I think you are missing my point. Gravity is a scientific fact and human experience has been aware of its force, I would assume, from the beginning. Black holes were discovered because it was an endeavor in exploring something based on an aspect of reality, i.e., gravity, that was established fact.
Aerodynamics dates back to the 17th century, and humans have been aware of, harnessing its effects, and even talking about human flight for many centuries. Birds in flight were an obvious empirical observation of an application of it. Airplanes were invented because of an endeavor to explore something based on an aspect of reality, i.e., aerodynamics and observation of various types of flight, that was established fact.
So my question is, where in reality do we get scientific fact and human experience to suggest that there is any plausible reason or way to explore how to get something from nothing, or self causation, or an effect without a cause?
