Click For Summary
Two Canadian astronomers propose that dark matter may not exist, suggesting that its absence could explain why it has never been directly detected. They argue that modified gravity theories face significant challenges in explaining various astronomical observations across different scales. The discussion highlights the difficulty in testing both dark matter and modified gravity theories in controlled environments, as both rely heavily on mathematical constructs rather than physical evidence. Critics emphasize that dark matter theories require faith in unproven entities, while modified gravity could offer a more straightforward explanation of cosmic phenomena. Ultimately, the debate centers on the need for empirical evidence to validate or falsify these competing theories.

Since a superficial review of this thread indicates it has drifted off topic, I'm locking it until one of our A&C mentors can review it and determine if any further action needs to be taken.
