| Time Dilation - the Brilliance of Einstein: | | | | Unusual Aspects of Time Dilation: |
| Probably the most "accepted" of all human intuitions | | | | - In the expanding Universe, "space" is expanding, not |
| is that the "passage of time" is a constant - | | | | "matter" - galaxies and solar systems retain their size |
| everywhere. All space science fiction, e.g. Star Trek, | | | | - the distances between galaxies increase; |
