In the Canonn thread, I provided a detailed report of the Gen Ship, and along with that I also started a discussion on the ship's speed, and how the logs seem to have a mysterious number, possibly a date which is running off of the Earth's clock. If it were true and the ship was using Earth Time to date the logs, then "a few days" for the ship was 84 and a bit years on Earth (time between Log 2 and Log 3). However, the doubt comes in to play where the latter logs have much less Earth Time between them (Where Doctor Munroe dies "two days ago", between Logs 3 and 4, only 30-something years have passed in Earth Time), where they somehow may of slowed down the ship in response to current events. Log 1 and Log 2 have a gap of only 8 years Earth Time, so I assume that either the ship was slowed, or the ship purposefully went slow from the beginning, and came alongside the asteroid matching it's speed and path, let the scientist do work, then accelerated to reach the speeds it would of been going, if the asteroid wasn't of interest.
Let's not rule out that the ship might of been doing any number of scientific studies, and reporting back to Earth some how. It
does have a huge transmitter on its nose.
Edit;
My main posts where I discuss my findings and theories on the speed are
