How does light travel through space?

 Light doesn’t travel through space. It propagates through space.

“Space” has certain properties like permittivity/permeability that allow light to propagate only at certain max speed that we all well know. Actions/reactions (electro/magnetic and vice versa), keep light propagating even for good - if the environment is superconductive.

These properties of space also tell light to propagate straight - if the space is homogenous.
If it is not homogenous - light can eventually bend.

As everything is made of waves, this can possibly also contribute to the mechanism of gravity.
