Jeff B says, I just watched a video that really helped me understand gauge fields. The idea is that what appears to us as forces is really a warping in some sort of space for gravity. This is similar to forces we often think of as fictitious like the Coriolis force. Is there a profound difference between the two ideas or is it just easier for us to explain away the Coriolais force as fictitious because it is so macroscopic? You know, I don't love the analogy between gauge theory forces and fictitious forces.
