SUMMARY
The discussion centers on the distinctions and similarities between dark matter and the historical ether theory. Dark matter interacts gravitationally but not electromagnetically, while ether was proposed as a medium for light transmission without gravitational interaction. The ether theory was discredited by the Michelson–Morley experiment, whereas dark matter remains a theoretical construct supported by indirect evidence. Both concepts serve as metaphors for phenomena that are not yet fully understood, but dark matter is currently viewed as a more viable explanation due to existing observational data.
PREREQUISITES
