The light is moving away from both me and the earth at 186k miles per second, right?
We're not used to thinking this way, we're used to thinking of something moving away from me at just 176k (186 - 10).
The key is time, right? My relative time is different than the earth's relative time.
Page 119 talks about sound being constant at 770 miles per hour. How is sound the same as light and how is it different?
