Full Idea
The idea that electromagnetic waves could be a reality in themselves, independent of any bodies, did at that time not occur to the physicists.
Gist of Idea
It was formerly assumed that electromagnetic waves could not be a reality in themselves

A Reaction
'At that time' is when they thought the waves must travel through something, called the 'ether'.
