Astronomy is a Pseudoscience

On the topic of astronomy there is a view that, for whomever may practice it, astronomy is a pseudoscience.

Being restricted by location and access, the astronomer is at a disadvantage. Astronomy does not, and can not, follow the Scientific Method; which is an empirical method of inquiry which demands that hypothesis is tested with experiment. The astronomer cannot put the stars under controlled experimental conditions to demonstrate ideas and come to the truth of a matter, as a chemist can do with his or her materials. The astronomer can only observe and interpret—a scientific fallacy which hinders truth and progress.

From Copernicus to Stephen Hawking, its practitioners publish works but fail to perform experiments to verify the hypothesis put fourth, such as the Expanding Universe - the hypothesis of the metric expansion of space. Scientists in other fields are expected to perform experiments to come to their conclusions, and so we must ask, why not the astronomers?

A Yale University astronomy course explains (Archive):

The Scientific Method
The Scientific Method is a method of inquiry, expected even of school children, where an experiment is made to confirm or disprove a hypothesis.



Without experimentation, the steps of the Scientific Method are unable to be fulfilled. The researcher of the science is left in the dark to build one hypothesis upon the next: A 'house of cards' model of nature without solid empirical foundations.
