Flat Earth Follies: Water Curving Around A Ball

Flat Earth Claim

Please show me any instance ever in the history of humanity where water has been observed curving around a ball? You won't find it because it doesn't exist. DEMONSTRATE IT. Not math, but a demonstration.

The Facts

Flat Earthers really have a thing for wet balls. Okay... I'm not going to judge.

All that is required for water to 'curve around a ball' is an adhesive force.

1. There exists a physical force of adhesion.

2. The rate of spin imparts an outward centrifugal force less than the force of adhesion.

Here is a fairly round rock that is holding onto water quite well despite the Earth's gravity pulling on it. This is because the adhesive force between the molecules of water and the rock surface are greater than the forces pulling them away.

WATER EASILY CURVES AROUND A BALL

Even when I spin it, the water can remain on it -- apparently you just need a force to make water both curve and stick to things...

On the Earth, as we've previously shown, the acceleration on a body due to the Earth's spin is tiny compared to the acceleration of Gravity - which itself is fairly small.  How do we know it's gravity and not 'density'.  Easy, we can remove the acceleration due to gravity and see what happens.


DENSITY CLAIM IS NONSENSE

What we find, as you see above, is that DENSITY alone doesn't do shit, you need an acceleration.

This is why the formula for the bouyant force is proportional to the density, the volume displaced, and the ACCELERATION OF GRAVITY.

buoyant force = p V g

GRAVITY ACTUALLY WORKS AND EXPLAINS OUR OBSERVATIONS

I've even heard (what must very uneducated people even among Flat Earthers) whine about "how can Gravity hold all the water of the Earth down but a tiny little insect can just fly away".

That is likely because they slept through the part of Physics where we learn that force is the acceleration times the mass. Every little tiny molecule of water has a Teeny Little Microscopic force of gravity acting upon it. Just as every little tiny molecule of the insect has a Teeny Little Microscopic force of gravity acting on it.

Fortunately, for the insect (and us), the electromagnetic force is many orders of magnitude (for our uneducated readers that means 10 times 10 times 10 a whole bunch of times, about 39 times). So even a tiny little chemical reaction is sufficient to overcome that very weak force of Gravity acting on the insect. We have considerably more mass than an insect so we experience a greater force due to Gravity, which is partly why your lazy ass cannot fly and only a few of us can manage a sufficient jump to dunk a basketball.

It's not hard to verify these things for yourself - you aren't required to remain profoundly ignorant and uneducated.

DIRECT MEASUREMENTS OF EARTH CURVATURE

How about directly measuring the curvature of the Earth itself?

Peter Leane did a very good job at a direct measurement in his video 'Curve of the Earth Measurement Ver 2'.

We can also measure the curvature by observing mountain peaks at different distances and noting that they APPEAR to shrink in every direction we go, just about equally.  I've shown this with Mount Diablo from Loomis and Mt Rainer.  Even McIntyre's OWN 'A Mountain of Evidence' showed the curvature despite his best attempts (along with a SOUND and detailed debunking here, even McIntyre had to admit to the errors).

And you can also measure this curvature using the Sun, or the Moon, or Polaris.

With gravity acting roughly equally in every direction and there being NOTHING other than the very slight counter acceleration due to the centrifugal force (which is a MERE 0.3% that of Gravity) so the NET FORCE, even at the equator there is no reason that the Earth could not hold the Water to the surface IN A CURVE.  So you'll need to do better mewling "SHOW ME THE CURVE, NO MATHS" like an infantile child.

I've shown you AND shown you the math that supports it.

Conclusion

Flat Earth has failed again.

We've seen that water easily 'curves around a ball'.

We've shown that the nonsense 'density' claim does NOT hold water but GRAVITY does.

We've shown that Gravity poses none of the hypothetical issues ascribed to it by the uneducated.

We've shown direct measurements of the curvature of the Earth itself.
