The Flat Earth and Sea Level

The Flat Earth and Sea Level

The Flat Earth hypothesis is dismissed by the mainstream as pseudo-science.

The flat Earth model is an archaic conception of the Earth’s shape as a plane or disk.

Many ancient cultures subscribed to a flat Earth cosmography, including Greece until the classical period, the Bronze Age and Iron Age civilizations of the Near East until the Hellenistic period, India until the Gupta period (early centuries AD) and China until the 17th century.

That paradigm was also typically held in the aboriginal cultures of the Americas, and the notion of a flat Earth domed by the firmament in the shape of an inverted bowl was common in pre-scientific societies.

The idea of a spherical Earth appeared in Greek philosophy with Pythagoras (6th century BC), although most Pre-Socratics retained the flat Earth model.

List of topics characterized as pseudoscience

Flat Earth – a theory that the Earth is flat rather than spherical.

However, there are situations where the Flat Earth model is actually employed by the mainstream because the behaviour of tsunamis is governed by the Flat Earth hypothesis.

NOAA 2004 Indian Ocean Tsunami Simulation

A tsunami , also known as a seismic sea wave, is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake.

When the global sea level was much lower some historic communities may well have been effectively confined by a perceived Flat Earth boundary wherever the land fell away precipitously at the edge of the continent shelf.

The continental shelf is an underwater landmass which extends from a continent, resulting in an area of relatively shallow water known as a shelf sea.

Much of the shelves were exposed during glacial periods and interglacial periods.

Similarly, it’s also possible that some historic communities were effectively confined by a perceived Flat Earth boundary if they lived around a “depressed fresh-water lake”.

The Black Sea (around 7,600 years ago)
A rising sea flood, recently disclosed [clarification needed] and much-discussed refilling of the freshwater glacial Black Sea with water from the Aegean, was described as “a violent rush of salt water into a depressed fresh-water lake in a single catastrophe that has been the inspiration for the flood mythology” (Ryan and Pitman, 1998).

Average depth 1,253 m (4,111 ft)
Maximum depth 2,212 m (7,257 ft)

Therefore, it appears the mainstream is not being totally accurate when it classifies the Flat Earth hypothesis as pseudo-science.

Personally, I’m not sure how to classify the Flat Earth hypothesis.

It’s one of those rare beasts where the context defines it as either observationally valid [i.e. tsunamis] or observationally falsified [i.e. the oblate earth].
