The iceberg didn’t know that the Titanic was unsinkable, so it did what icebergs do to ships that collide with them, which is to sink them, and down the Titanic went to the ocean floor.

As for “the ocean,” it is a very large body of water, which we keep mostly on the surface part of our planet. This particular ocean was The Atlantic one, which we keep in between Florida and Norway, roughly.

How large is this ocean? It’s sort of hard to grasp the scale of it. Try this: imagine a pitcher of water. Got it?

Now imagine 187 quintillion pitchers of water. Hopefully that helps.

Down near its floor, “the ocean” has pressures that exert approximately 6000 PSI, or 600 lbs on every square inch, which is sort of like being in a machine designed to turn cars into cubes, except that to turn cars into cubes, Dr. Google tells me, compacting machines only need to exert 2000 PSI.

A “submersible” is a vessel designed to go down to those depths, supposing that you are somebody curious enough about the deep that you are willing to shell out a lot of money to get into a vehicle designed—you hope!—to survive a trip into a vehicle compactor.

This submersible was known as “The Titan,” and a “titan” is the type of ancient god after which the Titanic was named, with nomenclature suggesting that the Titanic was like the Titan, and maybe it was.

Now, “rich people” are people who have a lot of money, and “money” is an innovative human method of make-believe that allows people to exchange goods and services with relative ease, and which is something that in modern society people need to have in order to live.

“Society” is simply the way human beings choose to organize rules and power and social beliefs in order to shape our shared human life together.
