>sun is 93million miles way and orbing the galaxy at half a million mph

>>9473012
What is wrong about that statement?
Besides the retarded units, of course.

>>9473024

To measure the distance of the distance of the sun you'd have to turn it off, then on again, and time how long it'd take for the light to get here, but this also assumes light actually has a speed.

If it's orbiting the galaxy at 500,000+ then the movements of the stars would not be as stable as they are. Parallax cannot explain it because of all of the other supposed movements that the earth is making too.

>>9473042
distance to the sun is measured by bouncing radar off of Venus

>>9473042
I hope you are baiting. Otherwise you are profoundly retarded.
You have no sense of dimensions. On the galactic scale, 500000mph is a slow speed. The angular velocity relative to the center of the galaxy is of less than 2x10^-6 degrees per year.
It takes the Sun more than 200 million years to complete one orbit around the Galaxy.
Do you understand that? Of course you don't.

>>9473058
>distance to sun is measured by measuring something that isn't the distance to the sun

>It takes the Sun more than 200 million years to complete one orbit around the Galaxy.

That's some cool sci-fi. How about some evidence.

>>9473076
What constitutes evidence for a tard like you?

>>9473079

Observable, measurable and repeatable scientific evidence.

>>9473086
You can check basic Newtonian physics doing experiments in your room.
You can then make sense of those facts that you don't believe. You will realise the math fit them.

If you haven't bothered to do so, it is your problem. Keep believing the Moon is made of cheese.

>>9473094

>the math fit them

Believing math = science

>>9473076
I'm not too sure about he details but they figured out that Venus is 0.3 AU
I'm sure they just take the radar distance at two different times when Venus is closest to Earth then just do some calculations based on the heliocentric model
It's basic astrophysics

>>9473213
>bouncing radar off Venus

Enough with the sci-fi already.

>>9473316
What makes you think we can't do that?

>>9472971
I dont know about equalibrium. Moon is getting farther from earth, I think its 3cm a year. At some point in future it will leave eaths orbit

>>9473334

It began as a meme but then it attracted actual retards.

>>9473334
That's about right.
Tidal forces are stealing angular momentum from the Earth's spin and pushing the Moon outwards. But it won't continue indefinitely. Someday the Earth will become tide-locked as the Moon is today. Each will permanently face the other as Pluto and Charon do.
Then the Solar tide (which is weaker than the Lunar one) will steal angular momentum from the Earth-Moon system and the Moon will begin creeping closer again. This will take a very long time. I forget if the Moon will reach the Roche Limit and break up before the Sun expands and engulfs us both.

Good thing we have the scientific method and mathematics
All we have to do is measure the Earth s curvature
We could apply aerial photography to this chart and find out if the Earth is as round as we ve been told.

What s the name of the scientific experiment that demonstrates and proves that a body of water, such as the oceans, can hold a convex shape?

>>9473490
>I have no idea what I'm actually talking about. I'm just regurgitating some shit other people who don't know what they're talking about said

>>9473490
After tidal locking, tidal forces will cancel, keeping the moon at the same distance from Earth. The expansion of the sun will likely occur before Earth/moon tidal locking. The moon will never hit the Roche limit.

>>9473567
I agree that STS program was a waste and bad idea in a first place but whole point is that funding less than fucking 0.5% of USA budget. If you compare it to even with 90's budget you will see that only thing that NASA needs is actual funding of at least 1%. Funny thing is that random Americans asked on a street said things like it's 20% right now.

>>9473563

I wonder if that s enough for NASA to make a educational video of them measuring the size and distance of the Sun and Moon?

But anon, his math is undeniable. Irrefutable. Incomprehensible. Nonexistent, even

i can't even

why not just say the angular momentum it had during its formation along with the earths gravitational field causes its tangential velocity to shift constantly?

>>9473213
They measure the distance to Venus and then you've got an earth-venus-sun triangle, with the angles given based on the phase of Venus, and then it's simply triangulation.

>>9472971
Topic aside, how did this brainlet meme come about?

>>9474155
but you don't have a triangle, you have a line
Also I don't think triangulation works in space

>>9474263
You're probably thinking of spherical geometry, where triangles constructed using great distances across the earth's surface don't behave normally because they're on the surface of a sphere (or ellipsoid; whatever) instead of on a flat plane.

In space though, there's nothing stopping us from just using euclidean geometry.

Why do we see the same stars every night through the earths rotation around the sun with only a small variance throughout the year? Yes there are different constellations but every 180 days or so we should be seeing a completely different set of stars. How does this make any sense?

The Earth is flat
The Sun and Moon are smaller and closer than we've been led to believe
Photoshop images are "science"
Metabunk is either running a social science experiment or they couldn't find someone qualified enough to render a third dimension to the towers fast enough to keep a lid on the Flat Earth.

They re are alot of photographs of those towers before Metabunk/Soundly claimed to have found the curvature of the Earth/convex water.

I think they re trying to make a monkey out of you, Anons

Why is the Earth flat and the Moon and Sun isn't?

If the Moon orbits above the Earth, do you have photographs of the underside of the Moon?

Third video conveniently overlooks the fact that euclidean geometry crashes and burns when measuring long distances across the surface of the earth. We have to use elliptical geometry for the equations to work correctly, which only works for shapes on a round surface.

>>9473076
You can calculate how far away the sun is just by using the period of Earths orbit you moron. If you don’t believe the equation is right you can measure the distance and orbital period of nearby planets to check your work. God damn this board needs a calculus captcha. Please mods!

Here's the deal: there are three types of Flat Earthers who regularly post to 4Chan: prankster intellectuals who troll to test your knowledge and debate skills, literal Bible interpreters, and most recently and proliferately: the juvenile-level troller. None of them provide any evidence of phenomena that require a flat Earth model to explain, but rather place the onus on you to prove the round Earth (again, and again, and again, ...). Their only recourse is to disavow any science or proofs put forward.

Trolls are easily identified by the memes that ostensibly 'prove' a round Earth is false, but contain geometry, maths, logic, and facts so absurdly wrong that you are compelled to display your superior intelligence and knowledge. By responding, you've taken the bait. Your posts (reasoned or prefereably emotional) are met with insulting or provocative responses. If you reference web-based information (that they could have looked up if they were interested) they will accuse you of being a shill for some absurd conspiracy.

They actually have no interest in the concept of a flat or a round Earth whatsoever. It's all about the lulz from getting you to respond. It is simply impossible to keep up with having to explain away the barrage of stupid posts, as the anonymous nature of 4Chan makes irresponsibility a tool of the prankster. Arguing is akin to painting over mud - you just end up with a dirty brush.
