We have consistently been told that light propagates through a vaccuum. My question is twofold:
What is this vacuum vacant of? (Unless we could reach temperatures below -273C, I cannot imagine that there is somewhere that electromagnetic waves are NOT present)
Where and when was this bold statement of propagation proven?
