This
Literally 90% of flat earth arguments can be debunked with either gravity or just not being a retard
>>8145745
They just counter it with gravity isn't a thing and earth just travels up at 9.81m/s/s.
Which is stupid for plenty of reasons
>>8145488
I like how flat earthers never work out the math beforehand and establish falsification conditions.
"Seems just about right, maybe" is not a sound argument, let alone evidence or proof.
>>8145766
> gravity isn't a thing and earth just travels up at 9.81m/s/s
they're getting stupider with each day
Arent most flat earthers just trolls or people who do this for the sake of debating?
Like, dont they just want people to question things, that they take for granted.
for example:
> gravity isn't a thing and earth just travels up at 9.81m/s/s
would explain a lot of effects of gravity and makes people come up with a better reasoning than "things fall down, duh"
Well at least thats what some people of the flat earth society are going for
>>8145810
Except if the earth was accelerating up instead of us towards it, all objects would fall at the same rate regardless of air resistance.
As for the debating part it's hard to say, I think it's split pretty evenly. Obviously there's people actually starting the groups like FES and people like b.o.b who believe their shit
Earth has a circumference of about 25000 miles
So the distance between the cities is 16/25000 of the way around the earth
Converting that fraction to radians, we have 2pi*16/25000 = 0.004021 radians, or 0.23 degrees
Wow so much curvature
>>8145834
That's a pretty good approximation but in truth the closest surface on earth that comes to that is the ocean. The rest of the surface is governed also by tectonic plates meaning it can get away with barely curving at all in places
and you can't use logic or facts to argue with the flat earthers. either you're personally part of the conspiracy or you're a sheep / you've been indoctrinated
>>8145889
Or you're the retarded one not them. Either way we lose

>>8145779
>>8145826
Actually that isn't necessarily true. The earth moving up at 9.8 m/s^2 would push the air along with it. If this is the case you can basically picture this as a 9.8 m/s^s wind pushing upward. Wind will travel around a piece of paper and a brick completely differently (if you don't believe this go to a wind tunnel and do the experiment yourself). So really your whole point is invalid, sorry try again.
>>8146008
they will tell you, that sun is a spotlight that only shines downward
>>8145745
Gravity itself disproves flat Earth. The flat disk would eventually pull itself into a ball
99% of flat Earthers simply don't simple don't understand gravity, They think it's a force that pulls stuff "down" rather than to the center of mass of a heavy object.

So how do people who believe in a flat earth overcome the fact that the moon is clearly visible as a sphere in the sky, or any other planets for that matter?
Do they argue its a disk permanently facing the earth or something? Which is even more retarded.
>>8146094
>Do they argue its a disk permanently facing the earth or something?
either that, or they will say, that the moon being round doesnt mean that the earth is
>>8146103
But when you consider gravity isnt it obvious a sphere is the default assortment that matter will combine into?
>>8146110
Gravity isn't real (to Flat Earthers). Instead, the Earth travels upwards accelerating at 9.8m/s^2.
>>8146110
of course
but to be fair, they think/argue that gravity doesnt exist and that the moon is much much smaller than it really is.
>>8146126
How does this explain the moon cycles?
>>8146126
How do they explain seasons?
How do they explain the north and south poles havING 6 months of darkeness
>>8146124
What is their explanation as to why gravity is differently strong in different parts of the world?
>>8145745
They can just be debunked with math, logic and common sense.
For a plane to fly into outer space it'd need to gain kinetic energy which can't be drawn from nowhere.
>>8146156
well, I dont know if that gif accurately shows their model. I think they believe the moon is not always in opposition to the sun as the gif shows it
and somehow, when it comes to this, the sun is now magically not a spotlight anymore

>>8146228
Planes altitude is adjusted to stay parallel to the ground. They lift their nose up to lift up, then they rotate back down to stay at the same level. The sum of velocity and gravity keep you at a constant height.
So planes naturally fly in curves to stay at the same level, they don't fly straight. And if they did fly straight, they would go out of bounds.

I guess, he thinks that this is what a straight trajectory means
>>8146008
>>8146008
Does this include distance? The sun could follow this format, but with it being 9,400 miles away (If it was in Australia and you live in the United States) you wouldn't be able to see that far.
I'm not a FE I'm just trying to understand if the picture debunks it fully. Because FE say the sun isn't nearly as big as Scientist say it is.

I mean technically if you were going fast enough you could have a flight path that looked similar to that, but even if you were going at nearly the speed of light the line would have a slight downward curve.
I wouldn't want to accelerate from zero to a gorillion miles an hour at sea level though, imagine the shockwave from that amount of heat and pressure.

Yes, it's actually measured in gpsi or gorillas per square inch. Going at such incredible speed means every inch of your body is covered in the force of a million gorillas all over your face and chest.

We aren't rewriting the whole physics textbook if the earth were flat dipshit.
If I jump out of a plane now I don't experience the wind moving in the same direction and speed as earths rotation. Why do I magically experience if it the earth is flat. Answer I wouldn't because fundamental truths of physics like inertia wouldn't change.

Even still heat will transfer the same, atoms will bond the same, inertia will still work how it does now etc etc

No rewriting at all

Who taught you that the way gravity works changes depending on your position in the universe?
https://en.wikipedia.org/wiki/Principle_of_relativity
>>8147188
Different guy here - do any popular flat earth memes change the way gravity works? I always heard shit about suggesting some magical unknown force is accelerating the earth-plate upwards to explain how existing observations of how gravity works still hold and yet the earth is flat.
When you are constantly changing the goalpost, it's not hard to say "but any experiment you can do agrees with it if we add this modification, and anything I can't think of so far is conspiracy until someone else suggests a way to sidestep that issue."
>>8147188
I at no point said anything about gravity being different within different frames of reference. What I was arguing was that we aren't rewriting every concept in physics. For some reason you seem to think that gravity is the be all and end all of physics and therefore if gravity changes so does everything else.
Congratulations, you have a fundamental misunderstanding of physics. I suggest rereading all those physics textbooks you seemingly understand so well.
>>8145666
>race don't real

>>8147205
Well, gravity is a fundamental force and the principle of relativity is also something very basic, so I dont know how I am the one who has a "fundamental misunderstanding of physics", when you are suggesting that "we aren't rewriting the whole physics textbook".
You also seem to not know all the other implications the flat earth "theory" would have on our current understanding of the world.
Anyway, according to the way you post, I already know, that you are too much of a faggot to admit, that you didnt put much thought in your original statement
>>8147210
what?
>>8147311
I'm not sure what the principle of relativity has to do with anything because I never argued against it. And we aren't rewriting the entire textbook.
There is no implications of the flat earth theory since there is no existing unified theory on what a flat earth actually looks or acts like.
Let's assume we're talking about disc earth because it's slightly less stupid than the others. Light would behave exactly as it does now, only it is no longer working in systems with gravity. Motion would be the same except without the gravity part as well. Entropy would mean the same. Sound waves would act the same, the list goes on. So no, we aren't rewriting all the physics books.

Segment height between two points 25,6km apart is 6371*(1-cos(25,6/6371/2))=0,013km which is 13m. So the highest point between these two cities is the height of a 4-5 story building, I don't know if you'd be able to discern if that's the case.
The circumference of the earth is 24,901 miles.
You can only see half of it at one time [half a sphere], or about 12,450.5 miles.
So you'd have to back up until you saw the 12,450.5 miles. Then you'd see from every angle it's curved.
You won't be able to see anything "straight".

>>8149747

>>8145666
>"no free will"
This does not belong. You obviously haven't studied or thought very deeply about the subject if you classify it alongside "flat earth".
>>8145512
At top speed, traveling around the circumference of the Earth, a 747 would change its angle by just 0.0023 degrees per second, meaning that the apparent upward centrifugal force on a 747 going around the world at top speed is a bit less than 1,000 pounds-force.
The thrust from the engines is 248,000 pounds, and the weight of the plane is more than 880,000 pounds. A deviation from horizontal of just 0.23 degrees would cause the vertical thrust of the engines to overwhelm it completely, or if the weight exceeded the lift by just 0.11%. So unless cruising planes maintain rock-steady horizontal flight to within better than 0.23 degrees, and their lift constant to within 0.11%, then the corrections needed to keep the plane flying straight and level and maintain altitude just from normal flight conditions would totally drown out the tiny upwards drift.

The curvature of a hollow Earth would probably make the motion of the Sun and Moon easier to explain than flat-Ethers have to deal with. And it's not like we haven't already seen "spotlight sun" explanations.
Actually, the curvature of a hollow Earth neatly patches several of the glaring objections to flat-Earth "theories". I should try and draw up my own shitty cosmology-conspiracy and see if I can annoy /sci/ with it some time.

Oh yeah. Funny how just a small detail in the wrong place can make all the difference.

Used to climb cell towers, anything over 1100ft and you can see the curvature of the earth. You are too close to the plane to observe the curvature. Like saying space isn't infinite because it looks flat from the surface of your planet... Which is just silly.
>>8145512
I enjoy how that post completely neglects the concept that the object in motion is in fact falling as it does so... Which automatically would account for the crafts ability to remain equidistant from the surface of the planet with a maintained thrust to weight ratio, it's speed is still not enough to escape or negate earth's gravity.
>>8145488
Man I really hate niggers.
Light bends to the left in positive refractive index materials, such as Earth's atmosphere. That shimmering you see over car hoods is caused by the fact that the photons cross a gradient of refractive indexes, and you'll note that the result is a smear of darkness surrounded by what appears to be blue air.
If you take a garden hose and point it up, you'll often note a spiral pattern to how the water is emitted from the hose, and how it comes back down to Earth. Light is doing the same thing - photons don't travel in straight lines.
On a sphere, light makes a series of curving arcs through the atmosphere, around the sphere. If the sphere is a dipole, the light will travel from ine pole to the other. The point is, all light on Earth does a curving orbit, and the result is a giant spiral across the surface.
Our eyes determine what we see - the position of the eyes relative to each other shapes the resulting image. By comparing the images received by the two eyes, a difference in perceived intensity can be discerned - this is the underlaying principle behind our perception of the horizon.
Birds, for example, see polarized light. What this means is that their eyes take note of the spiral of light - how the right-hand side gets flipped so it's now on the left. This allows them to reconstruct images that our eyes can't - they see what's beyond the horizon reflected in the sky above it.
To birds, the horizon looks further away. The shape of the Earth in this sense is very subjective, and using your eyes to deduce the curve of the Earth is very subjective and thus meaningless.
The stranger thing is that the concave Earth people have gone into the field, and substantiated their work. Given how subjective the horizon is, and how the convex Earth people report the same results but with the opposite sign, this would be the better avenue of inquiry.

Water is the best way to show the earths curve since it pretty much curves with the earth. People who use land experiments are retarded since they don't realise/forget that land doesn't conform to the earths curve but forms its own curves due to rainfall/tectonic activity.
