I'm going to have to think about this, Tina. Clearly you have a real
problem with /abstract/ -- that is, with things that don't have a
solid, concrete "thing" that they refer to. Most of this stuff is
like that. There isn't anything at the core that's solid,

If there isn't anything, there can't be anything that travels. Not solid
doesn't matter, as long as you explain what else it is. Right now, I
don't have an alternative to 'solid'.

What there is is a magnetic and electric field, at right angles to each
other and to the direction the light is traveling. A collapsing magnetic
field generates an electric field, a collapsing magnetic field generates
an electric field, so the pair alternately (as it were) generate each
other while zipping along at 180,000 mps more or less.
