Actually he did use experiments. His model was compared again and again with the actual motion of the planets and was always found to be perfectly accurate. Mariners could use his predictions to navigate the ocean (which is really all the purpose the model had for any living human at the time anyway).
The Coppernican model is actually the one that ignored experimentation.
Scientists Claim to Have Found The First Known Extraterrestrial Protein in a Meteorite
A new discovery could be a clue for us to see if life could emerge elsewhere in the Solar System. Using a new analysis technique, scientists think they have found an extraterrestrial protein, tucked inside a meteorite that fell to Earth 30 years ago.
If their results can be replicated, it will be the first protein ever identified that didn't originate here on Earth.
"This paper characterises the first protein to be discovered in a meteorite," the researchers wrote in a paper uploaded to preprint server arXiv. Their work is yet to be peer reviewed, but the implications of this finding are noteworthy.
Over the last few years, meteorites from the wider Solar System have been yielding some building blocks for life as we know it. Cyanide, which could play a role in building molecules necessary for life; ribose, a type of sugar that is found in RNA; and amino acids, organic compounds that combine to form proteins.
Researchers have now revisited the meteorites that yielded the latter. Led by physicist Malcolm McGeoch of superconductor X-ray source supplier PLEX Corporation, the team focussed their search for something more.
Using "state-of-the-art" mass spectrometry, they found what they believe to be protein in a meteorite called Acfer 086, found in Algeria in 1990.
While not proof of extraterrestrial living creatures, this protein discovery makes for yet another of life's building blocks to be found in a space rock. There are many processes that can produce protein, but life, as far as we know, can't exist without it.

Predictions which are then matched to measurement is the very definition of experimentation.
The experiments where to measure the locations and movements of celestial bodies and then match them to mathematically calculated equations which then fit observation.
To be honest I’m gonna give up with this thread. I see you promoting Greta Thunberg and the Democratic Party on other threads which fits perfectly with you attitude in here.
There’s only so much ignorance one person can exhibit before giving up on them.

In this case the data matched observation pretty well. Good enough for accurate calendars and navigational star charts.
Every voyage using Ptolemys work as the basis for navigation was an experiment.

Absolutely, as a man of science I totally agree.
My main issue is with the idea that Ptolemy was anything other than a scientist. In Reality he was a pioneer in the scientific field of Astronomy. Pretty good mathematician and geologist to boot.

Of course, with 2000 years of scientific advance I’m sure Ptolemy if he was alive today would see the errors of his way and use modern tools and methods to debunk his own ideas.
My argument has always been he was an early scientist and could only use the tools and knowledge available at the time. I guess my point when simplified is that his work was based on observation and measurement, theology had no part in his model.
Early Greek philosophers were hardly primitive, illogical apes as some on here would lead you to believe. In fact their work, especially Plato, Pythagoras, Hipparchus and Aristotle is the foundation of modern science.

Good so you agree with myself, dictionary and Brittanica that geocentrism is a scientific theory. Glad you can finally admit to being wrong.

Ok you’re clearly mentally ill. I said Ptolemy was a scientist and geocentrism was a theory.
Sat plenty of classes to achieve my degree in a scientific discipline then spend 20 years on the job in a scientific field.
What’s your background? I’d bed my life you’re just a kid that plays games all day.
