There is, of course, no way for a rainbow to ever be visible when the light source is always directly overhead (not to mention being rod-shaped rather than a point source), hence Sam’s confusion (Juni combined the Hiero words meaning ‘rain’ and ‘arch’ with a containment-conjunctive).

Meanwhile, the deep-space background is blue with tinges of infrared (I took some artistic license), so blue- and red-shift look a bit counterintuitive, with the background appearing purple and cyan, respectively. This is actually correct for a relative velocity of 0.027c. Deriving this, as well as determining how long they’ve been accelerating in order to be at this speed having traveled only about ¼ of the way to the galactic core from Earth, is left as an exercise for the reader; show your work, and don’t forget to account for the Lorentz effect, the increase in mass due described by special relativity, and increase in drag due to the interstellar hydrogen pressure front while accounting for the ramscoop feed, as well as whatever theories of dark matter, spatio-temporal expansion, and quantum velocity you subscribe to.

Incidentally, I may have too much time on my hands.

Transcript

Sam: It’s so quiet out here.

Juni: Peaceful, itn’s it?

Sam: I was going to say “uncomfortable.” It’s so quiet my ears are ringing.

Juni: Well, we could talk. We have a couple decis here.

Sam: Well, okay. So how big is this place? Where’s the hub?

Juni: There is no hub… our hub is like a tiny version of a star.

Sam: Tiny? Those are just specks. The hub is huge!

Juni: No, the stars are just very far away, so it’s hard to tell how big they are.

Sam: So why is the ground a different color over there than over there?

Juni: That’s… not ground, and I don’t know. Very strange. It’s almost like a rainbow.

Sam: What the breeze is a rainbow?

Juni:

Juni: Let’s pass the time some other way.
