OK, questions start here:

The Open University Science Foundation Course introduced me (in 1983) to the invariance of the speed of light. It took me some time to feel comfortable with that idea.

Now MS says: “No matter how you are moving, you are not moving relative to the Higgs field…….and it is possible for there to be fields that are at rest with respect to all observers!”

Is there some form of time dilation at work here?

Does this mean that it is not a particle’s motion through the Higgs field that gives it mass; because it is always stationary relative to the Higgs field?

There never was nothing.
