Leap second got me thinking.

The fish of the Devonian Period experienced rather short days. We know that the Devonian year had 400 days, making each day only 22 hours long.
Using lasers, we have confirmed this movement and found it to be 3.8 centimetres per year. This may seem too small to make a real difference, but when added up over hundreds of millions of years, we can calculate that the Moon is now twice as far from Earth as it was during Devonian time. As a consequence, Devonian tides were up to seven times larger than today’s tides.
There's a #gameable sci-fantasy world for you. Huge tides, short days, and a gigantic moon hanging in the sky.

The amphibimen crawl from their coral fortresses at low tide. Woe to the shore-dwellers.
ReplyDelete"Tides" is the name of one of my stars without number planets. It has multiple moons, and a binary star system so the oceanic planet has a ton of variables that play with its tidal system. The high tech inhabitants (sorry human, not amphibian) have learned to deal with it by having a flotilla city that is ever changing.
