Relative to what it was before. It has an intrinsic size. Think of it in terms of matter density if you find it more comfortable. The density simply goes down over time; distandes between galaxies increase.
- tengbretson 2y agoDensity has the same issue. Density can only be measured against a baseline established outside of the medium being measured.
- Doxin 2y agoJust because you can't measure something directly doesn't mean it doesn't exist. There's plenty of things we only know only through indirect measurement.
