This makes sense except for your last sentence. The equator is 21 KM further from the center of the earth than the poles. Now I understand that land masses vary in distance to the center of the earth and create a 'downhill' flow path, but the slant that would be required for the Mississippi to run 2300 miles to drain into the Gulf of Mexico is ridiculous when you consider it.
A very thought out and creative one trying to manipulate "facts" to make bullshit into "proof".
Let's see why:
In ericdubay's "200 proofs" list he claims that rivers such as the Nile, the Paraná, the Congo, the Paraguay, and the Mississippi "flow uphill". The rationale behind it seems to be that rivers which flow from north to south or south to north, and therefore towards the bulge at the equator, will potentially flow into mouths which are further from the center of the earth than their sources.
For
example:
4) Rivers run down to sea-level finding the easiest course, North, South, East, West and all other intermediary directions over the Earth at the same time. If Earth were truly a spinning ball then many of these rivers would be impossibly flowing uphill, for example the Mississippi in its 3000 miles would have to ascend 11 miles before reaching the Gulf of Mexico.
As with most all of Dubay's (and B(r)ushy's) 'proofs', no explanation or evidence is offered, and it appears he is merely quoting from one of the Victorian 'first-wave' flat earth texts. In this case, rather than Rowbotham, he uses
'Terra Firma: The Earth not a Planet', a scripture-inspired book written in 1901 by David Wardlaw Scott.
Whoever heard of a river in any part of its course flowing uphill? Yet this it would require to do were the Earth a Globe. Rivers, like the Mississippi, which flow from the North southwards towards the Equator, would need, according to Modern Astronomic theory, to run upwards, as the Earth at the Equator is said to bulge out considerably more, or, in other words, is higher than at any other part. Thus the Mississippi, in its immense course of over 3,000 miles, would have to ascend 11 miles before it reached the Gulf of Mexico!
How he arrives at the figure of 11 miles he doesn't say, though he does reference an 'Imperial Gazetteer' article, so it's possible he took it from this. In any case, I think we can assume that he did a rough calculation that went something along the lines of:
1. Earth's radius is 13.5 miles larger at equator than at poles
2. Length of Mississippi @3000 miles is 48% of the distance from the north pole to the equator (6215 miles)
3. Radius to mouth - radius to source = approximately 48% of 13.5
4. Answer is that the mouth is 6.24 miles 'higher' than the source (after subtracting 1,475 feet for the elevation at source)
5. Write down 11 miles, cause reasons.
Now, in actual fact the Mississippi is 2,320 miles long, while its 'as the crow flies' distance between source and mouth is 1,288 miles, and the distance between the lines of latitude at its source and mouth 1,248 miles. Using the above technique, this would make the mouth 2.44 miles 'higher' (further from the centre of the earth) than its source.
That's just a rough figure, of course, but one I would have expected a Victorian flat earth 'scientist' to have arrived at. And using more modern methods, such as a
geoid height calculator, I find a figure of 3.72 miles.
So there you go! The mouth of the Mississippi is not 11 miles higher than its source, it's a little under 4. Which is not an explanation of how this is possible, but another example of how Dubay (and B(r)ushy) repeats incorrect information without ever checking it, and yet presents it as fact.
The
explanation is a little more straightforward than the labored 'background check' above:
The Mississippi River (or any river flowing toward the equator) actually flows uphill. The Earth is not a perfect sphere. There is an equatorial ring about 13.5 miles deep. In other words “sea level” is not constant. It is higher at the equator than it is at the poles.
In the case of the Mississippi the difference is 4.12 miles. The source of the Mississippi, Lake Itasca, is 1400 feet above sea level, and the mouth is, by definition, zero feet above sea level. So we think of all of that water flowing downhill 1400 feet. But it is actually flowing against the force of gravity, going four miles uphill. The force that keeps the water flowing is actually the centrifugal force of the earth’s rotation.
If we did measurements of the flow of the water, only the effect of gravity would be observable. But that’s only because we’re using “sea level” as our reference in the first place. And the difference in sea level is itself caused by that same centrifugal force. So its effect is cancelled out in the measurements that we make.
Counter-intuitively, the gravitational force is much smaller than the centrifugal force. This is demonstrated by the fact that the centrifugal force lifts not only the water, but also the entire crust of the Earth, more than 13 miles at the equator.
Why my calculation was 0.4 miles different to theirs, I'm not sure. But similar enough to debunk the "11 mile" claim. And whatever the figure, the explanation is still the same.
