The discussion centers around the concept of ether, particularly its composition as understood by ancient civilizations, primarily the Greeks. Participants debate the definition of "ancients," with a focus on how ether was perceived in ancient Greek and medieval science. Ether was viewed as an intangible substance, akin to air, with properties like zero density and infinite rigidity. The conversation also touches on the transition in scientific understanding, referencing the Michelson-Morley experiment, which challenged the existence of ether. Additionally, there are mentions of ether as a volatile liquid used in laboratories, with a nostalgic note on its pleasant smell. The thread concludes with confusion over the original question posed, leading to a suggestion for a more focused discussion in a new thread.
