Is it just me or does the land mass and clouds in these digital illustrations not even conform to a spherical shape? It looks more like a looking glass if anything, especially with that exaggerated glow around the perimeter which makes absolutely no sense.

OK, you want curvature! As I said you just have to go high enough.

You may or may not accept it, but that's your problem, not mine.

If you're high enough to think those images are proof, I guess you'd believe the Star Wars planet Aldreaan is real too!


And Star Trek's "Genesis" planet!


And perhaps this one from The Little Prince...

It is just you! "The land mass and clouds" is a very recent photo of the globe. To my knowledge the ones in the previous post were not retouched at at all. This one of course is.
And before you ask. Of course it is a composite photo in the sense that it is the combination of signals from a number of sensors. I believe these satellites have sensors for eight separate wavelengths, covering at least the infra-red and visible ranges.

Somehow though I don't think anything would satisfy you!

Himawari 2016.04.26 03.30 UTC - circle
Looks pretty circular to me. Of course down the bottom right there is a little bit not lit by the sun You can see the sun's reflection just a bit above and to the left of centre.
But as I said before, I couldn't care less what you believe from now on. The most careful explanations get thrown back in my face.

Stop being an idiot. There is one very big difference! I can see that the cloud cover on the satellite photos matches local weather here - what I see outside, and what appears on radar and weather reports (yes, I know a lot of those come from the same satellites).

Now come up with some convincing photos of the flat earth! And I won't be convinced by "lack of curvature", unless you are very high.
Come to think of it, come up with ANY convincing evidence of the Flat earth, other than "It looks flat outside my window."

Almost all Flat Earthers seem to subscribe to the reasoning "I can't understand the Globe, that proves the earth must be flat!"

You're right about that, the visible-light images are a three channel composite of red, blue, and green, while the infrared and the water vapor images are composites of multiple infrared wavelengths.  Color-compositing is not unique to satellite photography, either.  It is how CCD and CMOS sensors in all digital cameras work.  In essence, EVERY photo taken today is a color-composite photo!

But of course when most people say "composite" they're not talking about color-composite, they're talking about stitching multiple small images into one large image, which is not how the Advanced Himawari Imager aboard these satellites is achieving the full-disk image.  The field of view is wide enough to capture the image in one shot.

No, but what I see on the satellite photoos is consistent with what I see outside and with reports of weather fronts, Cyclone location etc.

I suppose you think they have rows and rows of graphic artists painting all these pictures (and of course all the other "real-time" satellite photos we have available) so they can publish them every 10, 30 min or so. Some of you conspiracy nuts really are something.

So many millions know about the fake Globe, but aren't telling. Do you wonder we all laugh behind your your backs, but sometimes it all spills over.

What about you coming up with those photos supporting a flat earth. Or some sound evidence - I afraid I have NEVER seen any that is convincing.

So many of you are so negative, yet have any no sound alternative to the Heliocentric Globe.

The "exaggerated glow around the perimeter" is most likely the atmosphere.
Now show us some pictures of the so-called "atmoplane" above the so-called "flat earth".
Well.........Just show us some aerial views of the so-called "flat earth".......for a start  !

I went to a "Star Party" at Mc Donald Observatory in Texas several years ago. They had several telescopes aimed at various objects in the night sky. NASA must have been very , very  busy painting all those pictures on those telescopes to fool people into thinking they were seeing the real thing. There was one of a nebula and one of Saturn, with its rings.
All "fake" of course because at least some FE's say planets (including the earth) don't exist.

So you've never heard of computer animations and simulations, or deny that such things exist. Check.

So you reject photographic evidence if it contradicts your preconceived notions. For example, a view all the way across Lake Ontario, which is dismissed, ad hoc, as refraction somehow revealing scenery behind an obstacle in the way of the line of sight - even though refraction never behaves in such a way in any observable circumstance. But doctored photos that show a huge swell of water with an abrupt edge in the middle are regarded as real? Earth photos with "SEX" written in the clouds?

It's disappointing that think people continue to fall for such things even after the inconsistencies are pointed out. But those who do not receive the love of the truth will be sent a strong deluding influence that they will believe a lie (paraphrasing 2 Thessalonians 2:11).

So you're willing to completely dismiss it? I know you're trying to be funny or whatever, and it is troubling that animators at disney did that in a kids cartoon... but it doesn't bother you at all that it's clear as day without sex shaped clouds that a supposedly authentic photograph of the Earth from NASA has the word Sex in the clouds?

Wow, excellent examples of buildings disappearing behind the horizon bottom first!

Rough calculation time:

Using the first image, the bottom third of the CN Tower (1800 feet) appears to be obscured. So that's about 600 feet obscured by the horizon. The view was taken from Olcott Beach, 39 miles away.

From this information, we can calculate the height above water level of the person taking the picture: 54 feet. This seems reasonable if they were in a building looking out over the water. Keep in mind, this is without taking into account refraction at all. If we take into account refraction under normal conditions, we would get 9 feet. A reasonable height for someone standing on the beach.

Everything seems to be exactly as expected for a round earth. What's the problem?

Edit: Also, nice use of the classic "here, let me google that for you" response. Subtle, but snarky. I deserved that. :)
Try using lmgtfy.com or images.lmgtfy.com in the future to really crank up the snarkiness.

If you want to understand how mirages can obscure lower parts of scenery immediately above water, look up what "fata morgana" is. This for example is one long boat with its bottom half totally obscured by such a mirage.

[several images of Toronto]

None of these appear to be taken from across Lake Ontario. The first one appears to be taken from very high up in the middle of Lake Ontario. A helicopter perhaps? The second one appears to be taken from the South West somewhere, relatively close. The third seems to be taken from the South from over the water. If you want to prove a point, you need to specify where the picture was taken from, and why it demonstrates a contradiction with the earth being round.

Yep, those are pretty cool. I'm not sure how they are relevant though. None of the first three images demonstrate "fata morgana".

Sky is at sunset and has a bright orange glow - but no orange light is seen at all in the incident reflections of the waves in the water. See, those are the sort of obviously F-A-K-E-D composite pictures that I am literally amazed people look at and believe are legit.

The color of a bright sunset sky should be apparent in the water too, like this:

I literally just grabbed the first image from the search results provided by TheTruthIsOnHere. There are tons more like it.

Cloudy weather + rough water = dark water. Have you ever seen a big lake or ocean before? I see views like that all the time. Anybody else who has spent enough time around large bodies of water can confirm this.

I don't know what's wrong with you. Water surface reflects light and it should be sparkling with the color of the bright highlights glaringly visible in the sky. I live near the Pacific coast and have seen many, many sunsets over the ocean. I've seen them over bays. I've seen them over lakes.

If I were to have said I reject the photo simply because the lower portions of are occluded, but I didn't. The color of the bright orange highlights in the sky doesn't show in the water at all. I'd have to be an idiot to accept such a shoddy composite as real.

Good question.



h_1 = 600 feet (height obscured by the horizon)
h_2 = height of observer
a = distance to horizon from h_1 (600 feet)
b = distance to horizon from h_2 (observer)
R = 20,900,000 feet (radius of earth)
a + b = 39 miles = 205,920 feet

Use this equation for calculating height based on distance to the horizon:

h = R/cos(d/R) - R

Use the inverse of that equation for calculating distance to the horizon based on height:

d = R * cos-1(R/(R+h))

First calculate a using h_1. Subtract a from 39 miles to get b. Then calculate h_2 using b.

Edit: Be careful about rounding errors. These equations are very sensitive to rounding halfway through the calculation. I suggest putting it all into the calculator in one lump. Make sure your calculator is in radian mode. Better yet, put these equations into an excel spreadsheet so you can do it quickly repeatedly.
