Light travels at a finite speed, with the speed depending upon the medium. With mirages, the medium is air. In air, the speed of light is only slightly less than it is in a vacuum, and the speed of light in air depends upon the temperature of the air. Simply put, the speed of light is slightly greater in warmer air than it is in cooler air. In physics, we usually express this behavior reciprocally as the index of refraction, n:

158) If “gravity” magically dragged the atmosphere along with the spinning ball Earth, that would mean the higher the altitude, the faster the spinning atmosphere would have to be turning around the center of rotation. In reality, however, if this were happening then rain and fireworks would behave entirely differently as they fell down through progressively slower and slower spinning atmosphere. Hot-air balloons would also be forced steadily faster Eastwards as they ascended through the ever increasing atmospheric speeds.
There are rivers which flow east, west, north, an south - that is, rivers are flowing in all directions over the Earth's surface, and at the same time. Now, if the Earth were a globe, some of these rivers would be flowing up-hill and others down, taking it for a fact that there really is an "up" and a "down" in nature, whatever form she assumes. But, since rivers do not flow up-hill, and the globular theory requires that they should, it is a proof that the Earth is not a globe.
When the Sun crosses the equator, in March, and begins to circle round the heavens in north latitude, the inhabitants of high northern latitudes see him slimming round their horizon and forming the break of their long day, in a horizontal course, not disappearing again for six months, as he rises higher and higher in the heavens whilst he makes his twenty-four hour circle until June, when he begins to descend and goes on until he disappears beyond the horizon in September. Thus, in the northern regions, they have that which the traveler calls the "midnight Sun," as he sees that luminary at a time when, in his more southern latitude, it is always midnight. If, for one-half the year, we may see for ourselves the Sun making horizontal circles round the heavens, it is presumptive evidence that, for the other half-year, he is doing the same, although beyond the boundary of our vision. This, being a proof that Earth is a plane, is, therefore, a proof that the Earth is not a globe.
That the mariners' compass points north and south at the same time is a fact as indisputable as that two and two makes four; but that this would be impossible if the thing, were placed on a globe with "north" and "south' at the centre of opposite hemispheres is a fact that does not figure in the school-books, though very easily seen: and it requires no lengthy train of reasoning to bring out of it a pointed proof that the Earth is not a globe.
122) Quoting Allen Daves, “If the Government or NASA had said to you that the Earth is stationary, imagine that. And then imagine we are trying to convince people that 'no, no it's not stationary, it's moving forward at 32 times rifle bullet speed and spinning at 1,000 miles per hour.' We would be laughed at! We would have so many people telling us 'you are crazy, the Earth is not moving!' We would be ridiculed for having no scientific backing for this convoluted moving Earth theory. And not only that but then people would say, 'oh then how do you explain a fixed, calm atmosphere and the Sun's observable movement, how do you explain that?' Imagine saying to people, 'no, no, the atmosphere is moving also but is somehow magically velcroed to the moving-Earth. The reason is not simply because the Earth is stationary.' So what we are actually doing is what makes sense. We are saying that the moving-Earth theory is nonsense. The stationary-Earth theory makes sense and we are being ridiculed. You've got to picture it being the other way around to realize just how RIDICULOUS this situation is. This theory from the Government and NASA that the Earth is rotating and orbiting and leaning over and wobbling is absolute nonsense and yet people are clinging to it, tightly, like a teddy bear. They just can't bring themselves to face the possibility that the Earth is stationary though ALL the evidence shows it: we feel no movement, the atmosphere hasn't been blown away, we see the Sun move from East-to-West, everything can be explained by a motionless Earth without bringing in all these assumptions to cover up previous assumptions gone bad.”
apos;s-breadth, – if the Earth on which they fix them move at the rate of nineteen miles in a second? Indeed, to believe that Mr. Proctor's mass of "six thousand million million million tons" is "rolling, surging, flying, darting on through space for ever" with a velocity compared with which a shot from a cannon is a "very slow coach," with such unerring accuracy that a telescope fixed on granite pillars in an observatory will not enable a lynx-eyed astronomer to detect a variation in its onward motion of the thousandth part of a hair's-breadth is to conceive a miracle compared with which all the miracles on record put together would sink into utter insignificance. Captain R. J. Morrison, the late compiler of "Zadkeil's Almanac;" says: "We declare that this "motion" is all mere 'bosh'; and that the arguments which uphold it are, when examined with an eye that seeks for TRUTH only, mere nonsense, and childish absurdity. "Since, then, these absurd theories are of no use to men in their senses, and since there is no necessity for anything of the kind in Zetetic philosophy, it is a "strong presumptive proof" – as Mr. Hind would say that the Zetetic philosophy is true, and, therefore, a proof that Earth is not a globe..

If the sun is the center of the solar system (which is actually based on Pagan Sun Worship) and the earth is orbiting around it, then for this event in Joshua to occur, it would mean that the earth stopped spinning and stood still, not the sun. For the earth to suddenly stop spinning at its supposed 1000 miles per hour spin, it would have caused catastrophic devastation on earth. But, if the earth is flat and still, and the sun and moon rotate around and above the earth, then it would make perfect sense for the sun to stand still in order to prolong the day.
There is physical, scientific evidence that we do indeed live under a glass dome. Sun dogs are lines of light that reflect off glass. This can only happen if a light is shining on the glass.These can be seen in the sky when the sunlight is shining just right and reflecting off the glass dome above us. This wouldn’t happen without glass. They say it is from ice crystals in the air, but air and ice crystal move constantly and would not cause this temporarily fixed phenomenon. Furthermore, this would not be possible on a spinning ball with no barrier separating the air from the vacuum of “space and no glass for the sun to reflect off of. Sun dogs are proof of a flat earth dome made of glass.
The Astronomer Royal, of England, George B. Airy, in his celebrated work on Astronomy, the "Ipswich Lectures," says - "Jupiter is a large planet that turns on his axis, and why do not we turn?" Of course, the common sense reply is: Because the Earth is not a planet! When, therefore, an astronomer royal puts words into our mouth wherewith we may overthrow the supposed planetary nature of the Earth, we have not far to go to pick up a proof that Earth is not a globe.
163) NASA and other space agencies have been caught time and again with air bubbles forming and floating off in their official “outer-space” footage. Astronauts have also been caught using scuba-space-gear, kicking their legs to move, and astronaut Luca Parmitano even almost drowned when water started filling up his helmet while allegedly on a “space-walk.” It is admitted that astronauts train for their “space-walks” in under-water training facilities like NASA’s “Neutral Buoyancy Lab,” but what is obvious from their “space bubbles,” and other blunders is that all official “space-walk” footage is also fake and filmed under-water.
Also many fans have asked about the agreement that Rick and Roger made concerning their respective songs when they dissolved their partnership. When Roger Hodgson left Supertramp in 1983, he and Rick agreed that the band would not play Roger’s songs. Their agreement was for Supertramp to become a vehicle for Rick’s music and Roger would go forward with his future secured by his songs and his voice. This was not just a gentleman’s agreement; the publishing company and contract legally recognize which songs each songwriter actually wrote. Roger has contractual approval rights over the use of his songs and Rick for his.
her impossible to "represent" a curved line by a straight one, and absurd to make the attempt, it follows that a straight line represents a straight line and not a curved one. And, Since it is the surface of the waters of the ocean that is being considered by Mr. Young, it follows that this surface is a straight surface, and we are indebted to Mr. Young, a professor of navigation, for a proof that the Earth is not a globe.

Mr. Lockyer, in describing his picture of the supposed proof of the Earth's rotundity by means of ships rounding a "hill of water," uses these words: - "Diagram showing how, when we suppose the earth is round, we explain how it is that ships at sea appear as they do." This is utterly unworthy of the name of Science! A science that begins by supposing, and ends by explaining the supposition, is, from beginning to end, a mere farce. The men who can do nothing better than amuse themselves in this way must be denounced as dreamers only, and their leading dogma a delusion. This is a proof that Earth, not a globe.
7) The experiment known as “Airy’s Failure” proved that the stars move relative to a stationary Earth and not the other way around. By first filling a telescope with water to slow down the speed of light inside, then calculating the tilt necessary to get the starlight directly down the tube, Airy failed to prove the heliocentric theory since the starlight was already coming in the correct angle with no change necessary, and instead proved the geocentric model correct.

6) If Earth were a ball 25,000 miles in circumference as NASA and modern astronomy claim, spherical trigonometry dictates the surface of all standing water must curve downward an easily measurable 8 inches per mile multiplied by the square of the distance. This means along a 6 mile channel of standing water, the Earth would dip 6 feet on either end from the central peak. Every time such experiments have been conducted, however, standing water has proven to be perfectly level.
Starting with Indelibly Stamped in 1971, Davies shared lead vocals with Supertramp songwriting partner, Roger Hodgson until the latter's departure in 1983,[4] at which point he became the sole lead vocalist of the group. Davies's voice is deeper than Hodgson's, and he usually employs a raspy baritone which stands in stark contrast to his bandmate's tenor. However, he occasionally sings in a falsetto which superficially resembles Hodgson's vocals, such as on "Goodbye Stranger" and "My Kind of Lady". He also plays harmonica for the group.
The aeronaut can see for himself that Earth is a Plane. The appearance presented to him, even at the highest elevation he has ever attained, is that of a concave surface - this being exactly what is to be expected of a surface that is truly level, since it is the nature of level surfaces to appear to rise to a level with the eye of the observer. This is ocular demonstration and proof that Earth is not a globe.

Always keep in mind that tangible science is a flat earth, a ball dangling in the sky is science fiction or Hollywood. I believe the firmament to be an ice dome, described to be glass. The hotter we make the "planet" the more that dome melts, I believe the salt beds are salt dropped out of the sky as water evaporated to become air. Gods rendition is tangible science.
23) Ball-believers often claim “gravity” magically and inexplicably drags the entire lower-atmosphere of the Earth in perfect synchronization up to some undetermined height where this progressively faster spinning atmosphere gives way to the non-spinning, non-gravitized, non-atmosphere of infinite vacuum space. Such non-sensical theories are debunked, however, by rain, fireworks, birds, bugs, clouds, smoke, planes and projectiles all of which would behave very differently if both the ball-Earth and its atmosphere were constantly spinning Eastwards at 1000mph.
