But actually the words "matter" and "material" are not
fundamental concepts in (modern) physics.
To quote from
https://en.wikipedia.org/wiki/Matter
"... matter is not a fundamental concept because a
universal definition of it is elusive: elementary
constituents of atoms may not take up space individually,
and massless particles may be composed to form objects that
have mass (even when at rest)."
"Matter should not be confused with mass, as the two are
not quite the same in modern physics."

What do you do when your dream dies?
Dreams die in every life. But not Pham's
dream. He had pursued it across five hundred
light years and three thousand years of
objective time. It was a dream of a single
Humankind, where justice would not be
occasional flickering light, but a steady glow
across all of Human Space. He dreamed of
a civilization where continents never
burned, and where minor kings didn't give
children away as hostages.
