I like how the number 42 is weaved into this.

At 177 light minutes into the journey, there is the following message:

Emptiness is actually everywhere. It’s something like 99.9999999999999999999958% of the known universe.

leaving 4.2E-21 or 0.0000000000000000000042% non-emptiness in the universe.

I can't find any sources backing up this figure, but I wonder if it was the author's intent to smuggle in a Hitchhiker's Guide to the Galaxy reference.

Edit: Just saw the second reference to this at 208 light minutes.
