Is aether an element?
Excuse me, could you clarify something for me? I've come across the term "aether" and I'm wondering if it's actually an element, like hydrogen or oxygen. I understand that in some historical and philosophical contexts, it was used to describe a hypothetical medium that permeates space and allows the propagation of light and other phenomena. But is it considered a scientific element in modern physics or chemistry? I'm genuinely curious about this and would appreciate your insights.
