This kind of research is definitely falsifiable. If you read the article you'd see tons of graphs that are the result of actual direct measurement of phenomena.

This kind of research is definitely falsifiable. If you read the article you'd see tons of graphs that are the result of actual direct measurement of phenomena. These measurements are used to rule out some of the theories, and conform to other theories. Astrophysicists make predictions and run experiments all the time. The same is true for black hole theories.
