Did an Astronomical Body Cause the Global Floods of Ancient Myths with Its Gravitational Tidal Floods? - Part 2

Print

This is the concluding part of a two-part article that offers a unifying scientific hypothesis that connects diverse ancient flood myths with mainstream scientific fact.

Part 1 offered scientific facts which seem to tally with the many flood stories that exist around the world. Having established the likelihood of a massive global event, it suggested the possibility that an event of this kind could be caused by a close encounter by an astronomical object.

This section will consider whether the science allows this theory to be viable.

Read Part 1 here.

The Path of Destruction

Here, I have plotted all the flood myth locations as per Graham Hancock’s research and overlaid a possible ground track (see definition below) where the body’s gravitational pull would have generated the highest levels of tidal flood. In the Pacific Ocean this tidal wave would have spread out wide to hit the whole west coast of the Americas.

A ground track is the path on the surface of the Earth directly below a satellite. It is the projection of the satellite's orbit onto the surface of the Earth (or whatever body the satellite is orbiting).

A satellite ground track may be thought of as a path along the Earth's surface which traces the movement of an imaginary line between the satellite and the center of the Earth. In other words, the ground track is the set of points at which the satellite will pass directly overhead, or cross the zenith, in the frame of reference of a ground observer.

A gravitational cataclysm would not only cause immense tidal floods but also earthquakes, volcanic eruptions, and it would be followed by the associated volcanic winter, a freeze causing plants to die and species’ habitat destruction.

The Physics

So, how large would such a space body need to be and would it not affect Earth’s orbit? 

Gravitational Force

In order to calculate the gravitational force between two objects with masses of m1 and m2 , the equation is:   where G is the gravitational constant (6.67E-11 m3 s-2 kg-1), r is the distance between the two objects, and F is the magnitude of the force between the objects.

Some Facts, Numbers and Assumptions

Earth’s mass: 5.97237×10 24 kg

Moon’s mass: 7.342×10 22 kg 

Earth’s mean radius – 6371 km (3958.75 miles)

The Moon's average orbital distance at the present time: 384,40 km (238.86 miles)

Astronomical bodies larger than 400km (248.55 miles) have enough gravitational pull to assume a spherical shape.

The average height (amplitude) of oceanic tides caused by the moon is about 0.54 meters (1.77 ft.) As 80% of humanity lives near a coastline, or in lowland plains, a catastrophic supertide/tsunami that could devastate coastal valleys and flatlands needn’t be more than 50-100 meters (164.04-328.08 ft.) in height.

This means that the gravitational pull needed to create it needs to be a near 50-100 times stronger than the Earth currently experiences from the moon. This however doesn’t require an object 50-100 times larger than the moon, the gravity equation above allows us to have a much smaller body that flies much closer to the earth. This is because gravity is inversely proportional to the square of the distance. But not the mass. To illustrate this, imagine we halved the moon’s mass and at the same time brought it halfway closer to the earth, then the gravitational force would be doubled!

We can divide both these values by 50 to get a distance of around 8000 km (4970.97 miles) and a volume of around 400 km3, which translates to approximately 900 km (559.23 miles) diameter. This will give us a gravitational pull of 50 times the moon.

If my calculations and assumptions are correct, an object of around 900 km in diameter passing the earth at an altitude of less than 1000 kilometers (621.37 miles) (of average, rocky density) would be large and heavy enough to create a strong localized tidal uplift in the oceans beneath its flight path (approximately 50 times the current tidal amplitude). That is large enough to destroy most of humankind, and a large portion of the fauna, but small enough to not cause a major extinction event or to disturb earth’s orbital path and rotation.

Another great read is genius journalist Jim Marrs’ (RIP) Our Occulted History. Where Graham Hancock steers clear of Aliens, Jim Marrs does not. From ancient Sumerian clay tablets to modern NASA scientists. Is The Moon a hollowed-out spaceship? Do the Anunnaki, or other aliens still live among us? Well referenced & indexed, well worth a look. His Alien Agenda is a top read also.

Graham Hancock has moved on.

His latest book, America Before, makes a compelling case that it was a 21 year series of impacts that caused the great flood, wiping out Atlantis which was based on the American continent, both North & South.

He has been working with the Comet Research Group of scientists.
Much travelling & well researched, referenced & indexed.
Many fine line drawings & colour  photos, a beaut book.

Well worth a read. 

In North America there are Native American Legends that tell of terrible things happening way back in their history. Many call it the time of the Great Water Mountain when much of the earths waters were pulled to the North Eastern part of North America.for a short period of time. If you go to the satellite or topo map you see a formation In North East Canada that looks like a giant circle with rays from the center going all directions of the compass. These are moraines and two things can make them. One is a glacier, the other is moving water. If there was a Water Mountain, that would explain where all the whale and walrus skeletons came from here in the MidWest. These skeletons are about plus or minus 12,000 years old and none were fossilized.

This is the absolute best explanation I have every read. It is a bit heavy on the science, but it gives an excellent explanation for an astronomical body being the cause of the Great Flood

the page lists the Earth-to-Moon distance as 238 miles, but it is close to a quarter-million (250,000) miles distant. That's a lot of room for a large object to pass between the Earth and Moon.

The mass of the moon is approximately one-sixth of the Earth, resulting in surface gravity of about 1/6th of Earth normal (gravity on the surface of the Earth is not uniform, but close-enough for normal human purposes).

Thanks for the page and how a close-encounter could generate temporary flood-earthquake-volcano disasters.
