Some observations/speculation about attached Q post.
ST may refer to 1920 where S=19 and T=20. So 1920 to upcoming 2020 makes for a century which corresponds with (New) Age of Enlightenment insofar that was the century of philosophy – 1700s.
Go above 40K and ST may refer to an episode of Star Trek: The Next Generation, season 1, episode 24, "Conspiracy" What's interesting about that episode is its story related to Omicron Ceti (also known as the Whale) and the overall theme. https://www.constellation-guide.com/constellation-list/cetus-constellation/
