As for the evidence, there is plenty of it, that earth is a sphere/potatoe like object.
Just setup a laser and a target at one of the great lakes and drive the target out to sea. The aim point from that laser will drift upwards,
indicating that the target is sinking. If you get distance, the height above water table and the deviation from the original aim point you can use
pythagoras and calculate a triangle and with that, the curvature of earth.
If you want, I´ll pull you a picture from a weather satelite, clearly showing the earth is round. I guess they are all faked in realtime then. Every
The Chicago skyline is seen from 59 miles away, and it is not an illusion, or mirage, or so forth. One experiment used a boat, and filmed the skyline,
as they cruised along towards Chicago. It proved to be the real, actual skyline.
I've also heard about laser experiments proving curvature, while other lasers that prove it is flat, too.
The entire setup is one of the main factors, among others. It is not proof of one or the other side. All sides must agree on joint experiments, to be
fair. Not done, as yet.
Nobody uses a laser, or anything else, when they are surveying the ground, or water - over longer distances - factoring for any 'curvature'.....
Why don't planes need to account for the Earth's curvature? Every flight would REQUIRE a descent, if curvature existed. It cannot follow a curve
without a constant descent. Instruments would measure the descent, not a level flight, as it indicates on their instruments.
Which leaves you with the magical force called 'gravity'....the answer to all problems....
If we assume gravity exists, first of all..
And we further assume gravity is exactly what they claim it to be....
So now, we have to define what a 'level' flight means, and how a plane measures for a 'level' flight, within the air...
'Level' flight is simply a plane flying level in air, without a descent, or an ascent. Simple as that.
A plane does NOT measure any of the surface below it, in any way, here. It cannot measure the surface, 25,000 feet below, and it would make no sense,
either, as the surface changes over a flight, obviously.
How is level flight measured in air? Because, like the Earth's surface, the air moves along perfectly flat paths, above the flat surface of Earth.
Why wouldn't anyone have ever explained this, before?
Because if they mention how the air is level, above the ground, it might make more sense to see the Earth as a flat surface, also.
No matter, because the air must follow in flat paths, or else the plane's instruments would not be able to measure for level flights!!
Even if gravity existed, it would not explain this.
If we assume gravity exists, how could it make planes follow curvature, while the instruments measure it as level flight? It is measured within air,
for level flight, and for descent, or an ascent.
I argued with a pilot about this point, earlier on the forum. He claimed that gradients of air were curved like Earth, and planes followed the curved
air, but it was measured as level flight on instruments.
I pointed out that gradients, if they DID curve, were far too large for a plane to follow along, even if it WERE possible...
He left the forum, and never replied to me....
It is nothing to fear.
