`Epicycles are often cited as one of the biggest problems with the Ptolemaic #geocentric model. And that is precisely what Copernicus is taking aim at here. That’s not to say that Copernicus was fundamentally against epicycles. Indeed, his own adherence to uniform circular motion forced him to include #epicycles in his model. But what #Copernicus is criticizing here is the size demanded by the Ptolemaic model for #Venus in particular.`

I asked ChatGPT about alternative terminologies for dark matter:

Advantages of the Term "Cosmic Gravitational Anomaly"

Neutral and Descriptive:
The term "Cosmic Gravitational Anomaly" is neutral, avoiding assumptions about the nature of the phenomenon, while being descriptive of the observed effects on spacetime.

Encourages Exploration:
By not presupposing that the anomaly is due to matter, it encourages researchers to explore a wide range of possibilities, including energy-based explanations.

Improved Communication:
This term can improve communication with both the scientific community and the public, clearly indicating that the phenomenon is a gravitational effect observed on a cosmic scale.

So from now on it's called CGA. Thank you. #CGA #darkmatter #epicycles #phlogiston
