Why are certain constellations only visible from one side of the Earth at a time? Shouldn't we all be seeing pretty much the same thing?

Some might say..... that since space is full of liquid... Stars aint nothing more then fish shit floating around.
Space is a hard as vacuum. It's the vacuum pulling against the flat Earth that causes the effect we feel as gravity. Also, cell towers allow me to make phone calls when my rig/ boat is hundreds of miles offshore. In the ocean the signal is carried by trained electric eels and bottle nosed dolphins.

You learnt bery well Breh.
Tears man..... trained eels.
I had a dream where "Space" was a dirty old bum, and I was about to sock it in the face because, well it's a dirty old bum, but then I thought, there's something special about it...

Come gather round lemme show y'all how dumb y'all are real quick.
This is a hallway...On a supposed round earth....okay let's go with that for a sec.
The horizon is at eye level. All lines converge to a point. Half of the pic is the floor. The other half is the ceiling. Unless the crack has overtaken you, we can all at least agree on that.
This is a hallway again, except it was done in Cinema 4d.
Looks about the same right? The "difference" is that in 3d programs you work on a flat plane, X,Y,Z,
Once again, half floor, half ceiling.
Once again, half floor, half ceiling.
Once again, half floor, half ceiling.
Now look at this response and
understand why I'm to the pernt where I ain't got no mo talkin'.
If you can't figure out that the ground is gonna disappear to a vanishing point regardless of a flat or curved horizon, we shouldn't be having this conversation.
Here's a time lapse video of the supposed superior mirage...
The elevation of Sawyer, MI is 654 ft. https://en.wikipedia.org/wiki/Shorewood-Tower_Hills-Harbert,_Michigan
The elevation of Chicago is 594 ft https://en.wikipedia.org/wiki/Chicago
60 ft difference gives you 1205 ft of hidden height on a globe. The Willis Tower is 1,450′, 1,729′ to tip.
Mirage tho right?
I'm DONE!

just off subject or unintelligent?
you have yet to post proof on a flat earth map explaining the trip time
but sites like www.flightradar24.com document the flight path daily in addition to hundreds of commercial pilots' flight computers
here is the math to help you comprehend why your horizon argument is bullshit

Speechless. .. please tell me you don't have children....lol.. you've convinced me bruh.
So dumb, so dumb.
The vacuum ( a high pressure system) pulls against the earth's atmosphere (a low pressure system) causing gravity. And gravity simultaneously pushes all the earth's water, land, a planet with a molten core together, all stuck to the globe huh?
Dumb, dumb, DUMB.
vacuum is an absence of matter, so no air pressure water pressure etc... its zero ambient pressure vs the the bottom of the ocean where pressure increases exponentially the deeper you go-So dumb, so dumb.

Dumb, dumb, DUMB.
in other words a vacuum doesn't pull or suck with any force its the absence of external force that we are surrounded by in our atmosphere
over simplification: all matter generates a gravity field, the greater the mass the greater the gravity in our case its enough to keep an atmosphere around our sphere and our feet on the ground
Please
post proof on a flat earth map explaining the trip time by jet of Australia to Agentina
I really hope you are just a lonely dude in a basement and don't plan on procreating. Your reasoning is sorry as fuck. Like 3rd grade level. Taking pictures above the floor of a hallway as proof? You need to be level with the floor you dumbass.
IDK if this was touched on in this thread or not, but these articles happen to mention & addressed some of the questions that I raised. I am glad to see that I was not the only one. 
7 DIY experiments you and rapper B.o.B can do to prove Earth is round
BY NSIKAN AKPAN January 27, 2016 at 2:25 PM EDT
Musician B.o.B claimed this week that the Earth is flat, but how does a person confirm the Earth’s curves? Photo by REUTERS/Mario Anzuoni
“The Earth is round.” Teachers say it. Scientists say it. But how do they know?
I ask because an Internet conversation has surfaced among celebrities like former television personality Tila Tequila whereby they state the Earth is flat. On Monday, musician B.o.B took up the mantle on Twitter, spurring a spicy conversation with noted astrophysicist Neil DeGrasse Tyson. Tweets were exchanged on both sides, andeventually, rap songs too.
Miss Tequila and B.o.B aren’t alone. Flat Earth thinking dates back thousands of years, when early societies like the Sumerians, Babylonians and Ancient Egyptians believed that the planet resembled a pancake. Christopher Columbus is often miscredited for correcting this idea and discovering the Earth’s curves by not sailing off its edge, but in fact, it was Ancient Greeks, such as Aristotle and Pythagoras, around 2,400 – 2,600 years ago, who first proposed that the Earth was round.
But you’re not here for a history lesson. You’re here for experiments!
Any mere mortal can validate our planet’s shape with basic household items like lamps, rulers and soccer balls. So without further ado, here are seven ways that B.o.B, Miss Tequila or any round-Earth denier can convince themselves that the Earth is indeed round.
Experiment 1: Watch a lunar eclipse
Things you’ll need: functioning eyes, the moon, and a telescope (optional).
Every now and again, the Earth passes between the moon and the sun, completely blocking its light and casting a shadow across the moon called a lunar eclipse. If you look closely while this happens, you would notice that the Earth’s shadow forms an arc as it creeps across our view of the moon.
A combination photo shows the moon during a total lunar eclipse as seen from Mexico City, April 15, 2014. Photo by REUTERS/Edgard Garrido
You might respond, “You’ve shown the Earth is round, but couldn’t it be round, but still flat — a flat disc?” Well, your eyes and telescope would also spot the 3D spherical nature of the moon. The Flat Earth Society does admit that the moon, the sun and other planets are indeed spherical, but claim that the “Earth is not a planet,” and unlike other celestial bodies, is flat.
So let’s ignore the moon for now and examine the other member of the eclipse trifecta: the sun.
Experiment 2: Take a trip to San Francisco and Seattle
Things you’ll need: A flight ticket, a long straight stick and a tape measure.
As theoretical physicist Ethan Siegel explains in great detail, you, me and B.o.B have something in common: we can use the sun to witness the curvature of the Earth. Here is Siegel:
…the Sun reaches a much higher point (and shines for more hours during the day) during the summer months, and reaches a significantly lower point (and shines for fewer hours) during the winter…
In fact, if you charted out the Sun’s path through the daytime sky, you would find that it takes its lowest path (for the fewest number of hours) on the Winter Solstice — usually December 21st — and its highest path (for the greatest number of hours) on the Summer Solstice, usually June 21st.
If you constructed a camera capable of photographing the Sun’s path through the sky over the course of the year, you would find exactly this: a series of arcs, where the highest, longest arc through the sky was made during the Summer Solstice and the lowest, shortest arc was made during the Winter Solstice.
On a midsummer’s day more than two millennia ago, Ancient Greek astronomer Eratosthenes of Cyrene noticed this too.
While a scholar at the library of Alexandria, Eratosthenes heard of a deep well in the southward city of Syene (now Aswan, Egypt). Once a year on the summer solstice, the citizens of Syene noticed that sunlight reflected off the well’s bottom. They also saw that sticks and tall buildings cast no shadows, suggesting the sun was directly overhead. But in Alexandria, on the same day, Eratosthenes found that sticks did cast a shadow. By measuring the angles of those shadows and by hiring surveyors to measure the distance between Syene and Alexandria, he not only was able to calculate the curvature between the two cities but also the circumference of the entire Earth.
Luckily, B.o.B doesn’t need to travel to Egypt to replicate this test, he need only visit our West Coast.
How did Eratosthenes calculate the circumference of the Earth? Video by Math Centre
One of the keys to Eratosthenes discovery came from Syene being due south of Alexandria. Stated otherwise, they lie on the same meridian.
Luckily, the same applies to San Francisco and Seattle. If B.o.B were to ever perform in the two cities on back-to-back days, he could replicate the work of Eratosthenes himself. If he heads to a park on both days, he could jab a meter stick in the ground, measure the angle that the shadow makes with the ground at high noon and reproduce Eratosthenes’ calculation.
This experiment would work in any two cities on the same meridian, provided they’re 200 miles away from each other.
Experiment 3. Watch the sunset lying down
Things you’ll need: The ground and the horizon.

Perhaps B.o.B and his entourage don’t have the air miles for a trip between San Francisco and Seattle. No problem. All they need is a beach on the Pacific Coast (or an unobstructed view of the horizon).
As detailed by the folks at MinutePhysics, the horizon is one of the easiest ways to validate the Earth’s curvature. As the sun dips behind the horizon, it slips from your view in a bottom-up direction. If you watch the sunset while lying on your back, and then hop up as the last rays disappear, then you should be able to see the sunset again.
The same pattern applies to ships as they sail away — their hulls disappear from the bottom up. As MinutePhysics points out, if the Earth didn’t curve and the horizon didn’t exist, when you looked at Chicago from across Lake Michigan, you’d be able to see the the Rocky Mountains.
Experiment 4: Shadow games and time zones
Things you’ll need: a 3D globe or soccer ball, a 2D world map and a bright lamp.
It’s always daytime somewhere and nighttime somewhere else. Five centuries of calculations argue that’s because the Earth is a spinning globe upon which the sun’s rays strike from a single direction.
You can test this idea with a lamp, a soccer ball and a dark room. Put the lamp and ball next to each other on a table. Now, turn off all the lights, and then switch on the lamp. Half of the ball should be illuminated, while the other half remains dark. If you want a facsimile of how this works for us, then replace the soccer ball with a globe.
The Flat Earth Society offers an alternative: The sun is a sphere with a diameter of 32 miles that is located approximately 3,000 miles above the surface of the Earth. They argue that the sun moves like a crib’s mobile, circling above our flat planetary disc.
If the sun is a spotlight, then why don’t
we see sunbeams when they’re not shining
directly over us?
Image by Moriel Schottlender/smarterthanthat.com
The problem with this spotlight hypothesis is the sun doesn’t behave like a spotlight. Imagine you’re at a Broadway show, and you see a spotlight shining on a lead actor. You can see the light beams hitting their face, yet you’re sitting in darkness. But on Earth, you can’t stand in an open area and then look off in the distance and see the neighboring land basked in light.
That’s because the Earth’s curvature creates distinct places where light can land, which forms the basis of timezones.
Experiment 5: Ride a merry-go-round
Things you’ll need: a ball, a merry-go-round and an adjacent jungle gym to stand upon.
Have you ever wondered why hurricanes swirl in one direction? The reason is the Coriolis Effect, and as National Geographic demonstrates, you can witness the same effect on a merry-go-round.
In the video, a woman wants to throw a ball toward someone sitting across from her while spinning counter clockwise on a merry-go-round. But rather than go straight, the ball appears to curve and land to her right. What gives?
If you hang a camera from above the roundabout, like these scientists from MIT did, you can see what happens. The ball does move in a straight line, but as a catcher rotates on the ride, he moves out of the ball’s path.

In contrast, if the camera is attached to and spins with the merry-go-round, the ball appears to curve.

The Earth is wider at the equator, so it rotates faster there than at the poles. Wind wants to push across the planet in straight lines from areas of high pressure to areas of low pressure, but the Earth’s roundness and rotation make the air flows appear to deflect off course. Peering down from space on the Northern Hemisphere, hurricane winds appear to deflect right, while the opposite happens below the equator.
Alternatively, if you tried to toss a paper plane in a straight line from the equator to a friend in North America, it would appear to curve out of the way. The same would happen if you flew in a straight line from the equatorial city of Quito, Ecuador to New York City. As you journeyed north in the sky, the Earth would rotate beneath you, moving New York City out of your path.
Experiment 6: Travel to space!
Things you’ll need: buckets of money
Space tourism is another option for those interested in seeing the Earth’s curves. The trip will cost upwards of $40 million, but once there, a celebrity can capture all sorts of footage of the planet’s roundness. Just look at these photos from Guy Laliberté, the former CEO of Cirque du Soleil, who traveled to the International Space Station in 2009.
Or take a gander at any number of photos collected by astronauts and satellites over the last half century.

Aside from the sun spotlight concept, Flat Earthers present a wide variety of explanations to discredit everything written above, such as:
Lunar eclipses are caused by a second object in space — an anti-moon — that blocks our view of the regular moon. (But if that’s the case, why can’t we see the anti-moon at other times?)
Eratosthenes’ measurements didn’t validate the planet’s curves, but rather that the sun moves away and toward a flat Earth.
Flat Earther concepts don’t stack up, especially when placed against modern technology like global air travel…or telescopes.
Instead, their ideas require leaps of faith that far outpace a 5’0 teenager stretching his fingers toward a rim.

The trip will cost upwards of $40 million, but once there, a celebrity can capture all sorts of footage of the planet’s roundness. Just look at these photos from Guy Laliberté, the former CEO of Cirque du Soleil, who traveled to the International Space Station in 2009.
Or take a gander at any number of photos collected by astronauts and satellites over the last half century.

Aside from the sun spotlight concept, Flat Earthers present a wide variety of explanations to discredit everything written above, such as:
Lunar eclipses are caused by a second object in space — an anti-moon — that blocks our view of the regular moon. (But if that’s the case, why can’t we see the anti-moon at other times?)
Eratosthenes’ measurements didn’t validate the planet’s curves, but rather that the sun moves away and toward a flat Earth.
Flat Earther concepts don’t stack up, especially when placed against modern technology like global air travel…or telescopes.
Instead, their ideas require leaps of faith that far outpace a 5’0 teenager stretching his fingers toward a rim.

10 EASY WAYS YOU CAN TELL FOR YOURSELF THAT THE EARTH IS NOT FLAT
THE EVIDENCE IS RIGHT IN FRONT OF YOU

Earth From The ISS
The curvature of the Earth is visible in this 2014 photo, which ESA astronaut Samantha Cristoforetti snapped from the International Space Station.
This story was originally published on Smarter Than That in 2008. We are republishing a lightly edited version on Popular Science in light of recent interest in the subject.
Humanity has known the Earth to be round for a few millenia and I’ve been meaning to show more methods that prove the world is not flat. I’ve had a few ideas on how to do that, but recently got an interesting incentive, when Phil Plait, The Bad Astronomer, wrote about a recently published BBC article about “The Flat Earth” society. (Most recently, rapper B.o.B. went on a Twitter rant on the topic.) Phil claims it’s ridiculous to even bother rebutting the Flat Earth Society – and I tend to agree. But the history of our species’ intellectual pursuit is important and interesting, and it’s very much well worth writing about. You don’t need to denounce all science and knowledge and believe in a kooky conspiracy theory to enjoy some historical factoids about humanity’s quest for space.
On we go to the top 10 ways to know the Earth is unequivocally, absolutely, positively, 100% not flat!
1. The Moon
Now that humanity knows quite positively that the Moon is not a piece of cheese or a playful god, the phenomena that accompany it (from its monthly cycles to lunar eclipses) are well-explained. It was quite a mystery to the ancient Greeks, though, and in their quest for knowledge, they came up with a few insightful observations that helped humanity figure out the shape of our planet.
Aristotle (who made quite a lot of observations about the spherical nature of the Earth) noticed that during lunar eclipses (when the Earth’s orbit places it directly between the Sun and the Moon, creating a shadow in the process), the shadow on the Moon’s surface is round. This shadow is the Earth’s, and it’s a great clue on the spherical shape of the Earth.
Javier Sánchez
Lunar Eclipse
A sequential view of the lunar eclipse that occurred on April 15, 2014. You can see Earth's shadow crossing the face of the Moon, and the shadow's shape is curved because Earth is spherical.
Since the earth is rotating (see the “Foucault Pendulum” experiment for a definite proof, if you are doubtful), the consistent oval-shadow it produces in each and every lunar eclipse proves that the earth is not only round but spherical – absolutely, utterly, beyond a shadow of a doubt not flat.
2. Ships and the Horizon
If you’ve been next to a port lately, or just strolled down a beach and stared off vacantly into the horizon, you might have, perhaps, noticed a very interesting phenomenon: approaching ships do not just “appear” out of the horizon (like they should have if the world was flat), but rather emerge from beneath the sea.
But – you say – ships do not submerge and rise up again as they approach our view (except in “Pirates of the Caribbean”, but we are hereby assuming that was a fictitious movie). The reason ships appear as if they “emerge from the waves” is because the world is not flat: it’s round.
Moriel Schottlender
Ant On An Orange
What you would see if you watched an ant crawling toward you over a curved surface.
Imagine an ant walking along the surface of an orange, into your field of view. If you look at the orange “head on”, you will see the ant’s body slowly rising up from the “horizon”, because of the curvature of the Orange. If you would do that experiment with a long road, the effect would have changed: The ant would have slowly ‘materialized’ into view, depending on how sharp your vision is.
3. Varying Star Constellations
This observation was originally made by Aristotle (384-322 BCE), who declared the Earth was round judging from the different constellations one sees while moving away from the equator.
Moriel Schottlender
Stargazing On A Round Earth
After returning from a trip to Egypt, Aristotle noted that “there are stars seen in Egypt and…Cyprus which are not seen in the northerly regions.” This phenomenon can only be explained if humans were viewing the stars from a round surface. Aristotle continued and claimed that the sphere of the Earth is “of no great size, for otherwise the effect of so slight a change of place would not be quickly apparent.” (De caelo, 298a2-10)
The farther you go from the equator, the farther the ‘known’ constellations go towards the horizon, and are replaced by different stars. This would not have happened if the world was flat:

Stargazing On A Flat Earth
4. Shadows and Sticks
If you stick a stick in the (sticky) ground, it will produce a shadow. The shadow moves as time passes (which is the principle for ancient Shadow Clocks). If the world had been flat, then two sticks in different locations would produce the same shadow:
Moriel Schottlender
Stick Shadows On A Flat Earth
Imagine the Sun's rays (represented by yellow lines) hitting two sticks (white lines) some distance apart. If the Earth were flat, the resulting shadows would be the same length, no matter how far apart you place the sticks.
But they don’t. This is because the earth is round, and not flat:
Moriel Schottlender
Stick Shadows On A Round Earth
Because the Earth is round, sticks placed at distant locations will throw shadows of different lengths.
Eratosthenes (276-194 BCE) used this principle to calculate the circumference of the Earth quite accurately. To see this demonstrated, refer to my experiment video about Eratosthenes and the circumference of the Earth.
5. Seeing Farther from Higher
Standing in a flat plateau, you look ahead of you towards the horizon. You strain your eyes, then take out your favorite binoculars and stare through them, as far as your eyes (with the help of the binocular lenses) can see.
Then, you climb up the closest tree – the higher the better, just be careful not to drop those binoculars and break their lenses. You then look again, strain your eyes, stare through the binoculars out to the horizon.
The higher up you are the farther you will see. Usually, we tend to relate this to Earthly obstacles, like the fact we have houses or other trees obstructing our vision on the ground, and climbing upwards we have a clear view, but that’s not the true reason. Even if you would have a completely clear plateau with no obstacles between you and the horizon, you would see much farther from greater height than you would on the ground.
This phenomenon is caused by the curvature of the Earth as well, and would not happen if the Earth was flat:

6. Ride a Plane
If you’ve ever taken a trip out of the country, specifically long-destination trips, you could notice two interesting facts about planes and the Earth:
The Earth is different from other planets, that much is true. After all, we have life, and we haven’t found any other planets with life (yet). However, there are certain characteristics all planets have, and it will be quite logical to assume that if all planets behave a certain way, or show certain characteristics – specifically if those planets are in different places or were created under different circumstances – our planet is the same.
In other words: If so many planets that were created in different locations and under different circumstances show the same property, it’s likely that our own planet has the same property as well. All of our observations show planets are spherical (and since we know how they’re created, it’s also obvious why they are taking this shape). Unless we have a very good reason to think otherwise (which we don’t), our planet is very likely the same.
In 1610, Galileo Galilei observed the moons of Jupiter rotating around it. He described them as small planets orbiting a larger planet – a description (and observation) that was very difficult for the church to accept as it challenged a geocentric model where everything was supposed to revolve around the Earth. This observation also showed that the planets (Jupiter, Neptune, and later Venus was observed too) are all spherical, and all orbit the sun.
A flat planet (ours or any other planet) would be such an incredible observation that it would pretty much go against everything we know about how planets form and behave. It would not only change everything we know about planet formation, but also about star formation (as our sun would have to behave quite differently to accustom a “flat earth” theory), what we know of speeds and movements in space (like planets' orbits, and the effects of gravity, etc). In short, we don’t just suspect that our planet is spherical. We know it.
8. The Existence of Timezones
The time in New York, at the moment these words are written, is 12:00pm. The sun is in the middle of the sky (though it’s hard to see with the current cloud coverage). In Beijing, it’s 12:00am, midnight, and the sun is nowhere to be found. In Adelaide, Australia, it is 1:30am. More than 13 hours ahead. There, the sunset is long gone – so much so, that it’s soon going to rise up again in the beginning of a new day.
Moriel Schottlender
Time Zones
We have time zones because when the Sun is illuminating one side of the spherical Earth, the other side is dark.
This can only be explained if the world is round, and rotating around its own axis. At a certain point when the sun is shining on one part of the Earth, the opposite side is dark, and vise versa. That allows for time differences and timezones, specifically ones that are larger than 12 hours.
Another point concerning timezones, the sun and flat/spherical Earth: If the sun was a “spotlight” (very directionally located so that light only shines on a specific location) and the world was flat, we would have seen the sun even if it didn’t shine on top of us (as you can see in the drawing below). The same way you can see the light coming out of a spotlight on a stage in the theater, even though you – the crowd – are in the dark. The only way to create two distinctly separate timezones, where there is complete darkness in one while there’s light in the other, is if the world is spherical.

Debunking The "Sun As Spotlight" Theory
9. The Center of Gravity
There’s an interesting fact about mass: it attracts things to it. The force of attraction (gravity) between two objects depends on their mass and the distance between them. Simply said, gravity will pull toward the center of mass of the objects. To find the center of mass, you have to examine the object.
Moriel Schottlender
A Sphere's Center Of Mass
Consider a sphere. Since a sphere has a consistent shape, no matter where on it you stand, you have exactly the same amount of sphere under you. (Imagine an ant walking around on a crystal ball. From the insect's point of view, the only indication of movement would be the fact the ant is moving its feet. The shape of the surface would not change at all.) A sphere's center of mass is in the center of the sphere, which means gravity will pull anything on the surface toward the center of the sphere (straight down) no matter where it's located.
Consider a flat plane. The center of mass of a flat plane is in its center (more or less – if you want to be more accurate, feel free to do the entire integration process), so the force of gravity will pull anything on the surface toward the middle of the plane. That means that if you stand on the edge of the plane, gravity will be pulling you toward the middle, not straight down like you usually experience.
Moriel Schottlender
A Plane's Center Of Mass
A plane's center of mass is in the middle—which means that gravity should pull objects toward the center of the plane.
I am quite positive that, even for Australians, an apple falls downwards, not sideways. But if you have your doubts, I urge you to try dropping something – just make sure it’s nothing that can break or hurt you.
Further reading about the center of mass and about distribution of mass can be found here. And if you are brave enough to handle some equations (not involving integration), you can learn some more about Newton’s Law of Universal Gravitation here.
10. Images from Space
In the past 60 years of space exploration, we’ve launched satellites, probes, and people to space. Some of them got back, some of them still float through the solar system (and almost beyond it) and transmit amazing images over to our receivers on Earth. And in all of the photos, the Earth is (wait for it) spherical. The curvature of the Earth is also visible in the many, many, many, many photos snapped by astronauts on the International Space Station. You can see a recent example from ISS Commander Scott Kelly's Instagram right here:
You know what they say—a picture is worth a thousand diss tracks.

6. Ride a Plane
If you’ve ever taken a trip out of the country, specifically long-destination trips, you could notice two interesting facts about planes and the Earth:
- Planes can travel in a relatively straight line a very long time and not fall off any edges. They can also circle the Earth without stopping.
- If you look out the window on a trans-Atlantic flight, you can, most of the times, see the curvature of the earth in the horizon. The best view of the curvature used to be on the Concorde, but that plane’s long gone. I can’t wait seeing the pictures from the new plane by “Virgin Galactic” – the horizon should look absolutely curved, as it actually is from a distance.
The Earth is different from other planets, that much is true. After all, we have life, and we haven’t found any other planets with life (yet). However, there are certain characteristics all planets have, and it will be quite logical to assume that if all planets behave a certain way, or show certain characteristics – specifically if those planets are in different places or were created under different circumstances – our planet is the same.

He will say all of those facts are bullshit. LOL. Cause the sun is 36 miles in diameter, but has been burning for 6 thousands years. It's doesn't run out of light cause it's solar powered.
Nah, you aint addressed shit but you being a real bitch right now. When you cant answer something you say you done, but then you come back posting more unrelated shit anyways. Just to make sure you avoid the questions asked. If you say you done then be done already.
And a bonus for tha bitch that run up on us.
Your mic dropping skills are turrrible.....
Man the way he snuck that im an engineer shit in there and had to be asked to qualify that for 15 damn pages, I'd take that college level educator shit with a Volkswagen sized grain of salt.^^^^^^
This....... And this guy supposedly teaches people.

There are no perfect spheres in Nature. All spheres have a north and south pole like fruit.
At the northern most top of the earth and southern most bottom of the earth it goes inward, hence Inner Earth. This is why your not allowed to fly over the south or north pole. This is far as I'm going to lead you the rest is up to you.
