Proof the Earth is round

[VonBonfire]

I already posted what Earth looks like, just study surface tension. We are almost a ball but bulge a little in the southern hemisphere but it is virtually unrecognizable.

Maybe da earf is like a cosmic pinball being bounced around the galaxy. I like you more now that I know you dig pinball. Video games ain't got nothing on pinball. I changed my mind and decided we should be friends.

Did I ever tell you that you have class? Class AND taste. Where the heck do you find a joint with this many pinball machines in 2024? You got a time machine do you?

Yes but it's Atomic Pinball

I am honored, BonVampire.

I’d like to see one of those

I haven't really done a lot of digging into flat earth the past couple years but maybe I will kick around the net the next few days and see if I can find you some of those. This site might be to your liking, as the writer "debunks" Eric Dubay's 200 flat earth proofs. I don't consider it a very thorough debunking but you might enjoy some of the material there. Note: it is basically an anti-flat earth website.

It's goofball shit mang. I am a consipiracy theorist but the flat earth troll ran it's course. Many hilarious memes have launched from it, amazing they could escape the firmament.

Eric Dubay is a weirdo screwball. But he does have some solid points in some of his arguments. *shrugs

You're asking for examples of people or organizations that lied to get power and money? I don't even know where to start. Remember the joke about politicians, "How do you know when they're lying?"... https://www.cnn.com/2013/11/24/politics/presidents-lie/index.html

We all know politicians lie

I still don't understand how 1,000's if not 10,000's of people have kept our flat earth a secret from 7+ billion people for say....100+ years.

And they want us to believe it is round why?

Thanks - you are the best debater on this forum. Always cool and collected

I think where a lot of these fall short is they don’t consider the size of our planet. It’s really big. The distance from the deepest ocean the tallest mountain is barely a layer of “skin” on the earth. Mt Everest is a dimple on a basketball.
The oceans seem vast to us, but again, negligible compared to the rest of the planet. Yea the surface is covered with them but our bodies are covered with hair. Shave it all off and compare that to the mass of the rest of your body… it’s miniscule.

Shrinking our planet down to manageable sizes makes things clearer in my opinion. People think “the earth is spinning at 1,000 miles per hour! Why aren’t we flying off??”

For a little perspective: for someone looking at the earth from space it is spinning 1 time per day. 1 revolution per 24 hours. Doesn’t sound very scary when you think of it that way. I read somewhere a dude that did the math, scaling down the earth to a basketball. I’m paraphrasing but the earth’s diameter is roughly 24,000 miles, and it’s spinning at 1,000 miles per hour.


Break the earth down to 24 time zones and that means each time zone is about 1,000miles wide. Again traveling at 1,000 mph means roughly “one time zone per hour”. If you were watching earth form space, one time zone would pass by your eyes every hour.


Scale that down to a basketball. Split evenly into 24 “time zones”, each zone would be like 1 1/2” wide. So using the same “one time zone per hour”, the basketball would spin like an inch and half per hour to the observer. Again, not very scary. If the ball was wet you wouldn’t expect it to go flying off of it spinning at that rate.

Now of course the basketball isn’t actually spinning 1000mph, but for me it puts things in perspective. We are but specs of dust to the earth. Most people can’t watch the earth spin from space, but if they could, it would look like a basketball spinning an inch an hour.

I guess basically what I’m saying is, for anyone that wants to make sense of some of this… zoom out.

I'm going to call flat Earthers out in the plainest possible way in the language that I grew up with i.e. not PC. To sum it up, they are spastics.

When I'm talking about curved water, I'm talking about the property of water where it naturally finds it's level, which you can see and measure on your own. A curved earth doesn't have flat water anywhere — there is always some degree of curve. Yet I have never seen anyone demonstrate this curve, even with all the sophisticated instruments of measure that we now have, such as lasers and so on. In fact, I have seen people demonstrate the opposite over thousands of feet (Lakes on a still day).

W.r.t "water finds it's level" that's just a restatement of "I can't see the curve", not some general law of water behavior. As far as demonstrating the opposite with lakes, how many thousands of feet are we talking? Here's a link to a paper (which I need to read closer still so not wholly endorsing it) that suggests the minimum height to see the curve is going to be around 35,000 ft. And that at that height lots of people don't see it, and that 50,000-60,000 is where most agree they definitely see it. There is also a neat section on how camera lens distortions make a lot (most?) pictures showing the curve suspect, and how to avoid this. They also have a picture supposedly demonstrating the curve taken this way. They also discuss issues like discerning the horizon despite it not being a clear cut line once you're at some distance from it.

Money shot picture, showing that a horizontal line connecting two points on the ends of the horizon is lower than a point in the center of the horizon, indicating that the horizon is bulging up in the middle. 'cause of the earth's curvature.

Regarding acceleration, we simply don't ever feel it. Ever. One would think that at least there would be an occasional blip that changes acceleration to the point we could detect it. But that has never happened in recorded history. Regardless, the point is that your own senses tell you that you are on a stationary, non rotation plane — not a spinning ball.

Why would there be a blip? In uniform circular motion, acceleration is constant, unchanging. And, why would you expect to feel anything discernible? Per the numbers I crunched, the required acceleration is tiny compared to the force of gravity, so it seems likely you wouldn't feel it. Which brings me to your last point, on which I disagree. Your own sense tell you that to the precision which they can measure you are not accelerating and the earth around you is flat. Even that's not quite correct though, as there is evidence you can collect with your senses that indicates a spherical earth. Also notice I said accelerating. You can't tell the difference between being in one non-accelerating frame or another, so even if you don't feel (or measure!) acceleration you could still be moving, just with constant direction and speed. In the case of the earth though, there must be some acceleration to keep you moving in a circle.

I would like to perform the laser experiment myself at the very least.

Post links, start a thread, etc. Citizen science at rig-talk. If it's not too much of a hassle I might try it myself just 'cause it's fun.

 

[7704A]

Seems many people have tested that across large bodies of water and found zero curve. The globe earth defenders will just cry "bias confirmation" and pretend like the tests never happened.

A big issue is that just because an experiment fails doesn't necessarily disprove the phenomena under question. It needs to be known why it failed, whether there were any issues with the method, conditions, etc. Undergraduate physics majors in their course labs get results that are imperfect or contrary to accepted theory all the time, but we don't throw out electricity, newton's laws, or whatever else because of that. Doing good, solid experimental work is a skill, and there is a high standard to meet for something to be acceptable as evidence. It is certainly interesting that apparently some number of people have tried an experiment and found no curve, however it's pretty likely there is something wrong with their experiments as indicated by @MadAsAHatter, especially if they aren't familiar with all the things that can go wrong in their measurements. Do you have any details on these experiments? Could be fun to dissect.

Yes. Refraction always gets the blame. Not sure how that works. If there is refraction then pretty much all apparent visuals could be called into queston? The earth could appear as a ball through terrestrial observations made because of it. It seems like a convenient excuse or something that could be fooling them too.

It's not refraction that's to blame. It's poorly designed, uncontrolled experiments that don't take interferences into account and make no attempt to remove said interferences.

If you were watching earth form space, one time zone would pass by your eyes every hour.

Yeah but if you were watching it from stationary position 6 feet above Earth it would be flying by at 1000 mph. That's the relevant perspective.

Oh yeah, we're also "orbiting" the center of the milky way yummy nougat center at 448,000 mph
