    Actually that's EXACTLY what it means. It's a function of light travelling in straight lines. I've got an actually flat marble counter, and there's no way of getting anything disappearing over its "horizon".

    You said you had photos from the beach. So post them.

    And once you've posted the photos from the beach maybe you could post a survey of the football field proving it is dead flat?

    Hey all,

    I'm a long time (almost everyday) lurker.. I think I only ever posted in the welcome thread. First off I am NOT a flat farther, and this website has helped me drop a lot of other CT belief's that I previously had. However, I was wondering what happened with the pictures JTNolan was discussing. Were him and Phillipe the same person? lol ... Was he trolling or trying to prove a Flat Earth? I couldn't really tell what he was arguing about and then it appears he was banned. It seemed the conversation was never finished or maybe moved to a different thread. Also, I realize this post is almost a year old, so, if no one sees this post and I'm forever left to ponder about the infamous JT ... I'll survive.

    Thanks

    Thanks, I appreciate it ... flat earth YouTube channels and Blogs are never guilty of bias towards a specific opinion ;) .. I'm currently in my 3rd year of College studying Psychology and I honestly find this FE stuff so fascinating. Especially reading their comments on YouTube.. they contradict themselves so often; accuse others of virtually everything they do; and seemingly only trust people with absolute zero credentials. It really is quite baffling.

    I believe that this is the most comical (and also irritating) aspect of the truly "all-in" conspiracy theorists.

    The constant yammering about how people need to "wake up" and "open their mind". Referring to those who raise opposition to their beliefs as "sheep"... "brainwashed"... whatever. Very predictable and [...] stuff. Yet, these people are as indoctrinated as any hardcore religious [people] you'll find out there. When a terror attack, a mass shooting... etc... occurs they run [...] towards the first YouTube videos that bring about hints of a conspiracy. Never do they question the assertions made in those videos. Never do they attempt to debunk the claims made there.

    Personally, I find it especially irritating. Seeing as I used to be one of those people... So... A) I see my past self in them, and it brings about some embarrassing feelings. B) Being told to have an "open mind" about something like 9/11 is just so ludicrous. I was a truther for the better part of a decade. I know all of your arguments backwards and forwards. Not only that, I know how to debunk them. So... it's frustrating to hear that. Even when I mention to them "I was a truther"... They go "suuurrre you were" and roll their eyes.

    Ugh...

    It's a weird mindset to describe. Like any other belief system -- it's a trap which you cannot see until you are clear of it. Many never get there.

    The first photo above is a nice shot of Catalina. Could be better detail, though. There's a bush in the way on the left side! Whenever I see a shot like this that shows the SE end of the island from the L.A. shore, and it's going to be compared to a similar view taken from near the water level in order to demonstrate Earth's curvature, I hear myself saying, "If you'd only zoom in on Avalon, we'd be able to see the Casino from here."

    The reason is, from that high point on the Palos Verdes bluffs on a clear day the Casino appears to be setting right on the water. But it's a lot like the hotel in the OP, being built just a few feet above mean sea level. So it's an excellent subject to make comparison photos that show how much gets covered up when you take another telephoto from the beach surf line under the bluffs.

    Twin Harbors (locals call it "the Isthmus") is good, too, and obviously larger so it's easier to see, but somehow it's not quite as impressive as the Casino. Also, the far right end of Catalina, the NW point, tapers down like a spear point right into the water. There are online images of that taken from helicopters so it's easy to get a good 3-D look at the contours of the rocks. You can't really see all the way down to the NW end of Catalina where it fades away into the ocean, from the PV bluffs, but you can from the top of the PV hilltop nearby. In Kansas they'd call that a "mountain." But this is L.A. where mountains are 8,000 ft tall! That long pointed rocky finger at the NW end can't be seen at ALL from a viewpoint at the beach surf line at PV.

    I spotted an opportunity to conduct a little experiment myself yesterday

    This ship was off the coast , this was the view of it from crouched down near the high tide mark (cropped)

    crop1.


    I walked inland around 230m and up around 25m according to Ordnance Survey

    And this was the view from the top (cropped)

    Nice. Interestingly though, even though it looks at first glance like it's partly hidden, there's probably a lot less hidden than you think. Refraction is significantly compressing the bottom part of the ship.

    Drag slider to compare. I've lined it up with the tops of the masts which will have the least refraction.

    Those are interesting photos, but they appear to be two different ships, for many reasons. Where you have, "The view from higher up and closer" would therefore be a mistake. It's a view of a different ship, from a vantage point higher up and closer.

    The towers don't match, the second photo showing three prominent towers and the one in the aft has a sphere top, but the first photo has only one tower in the center and no such sphere. The rectangular vents on the port side of the superstructure are entirely different (one vs. four), the profile of the forward gun is two different types of housing, the forward vertical wall of the superstructure in the first photo shows a step in the wall but the second photo shows no step at all.

    Certainly since these are both approximately the same length, they could be expected to have similar heights and hull exposure, so they're comparable for purposes of overall appearance. But it would be nice to have a photo of each close up so we can compare their profiles without any distraction of waves and atmospheric conditions.

    This comparison thingy you did here is quite remarkable, Mick. When I first slid the bar back and forth, it was obvious a great difference was going on, especially with the compressed appearance of the distant ship on the left. I would never have picked that out without your sliding comparison feature!

    I would like to point out two things perhaps significant:
    First, in the photo on the right, a white spray is prominent under the bow where the ship is cutting through the water, whereas there is no hint of this white water plume in the left photo, therefore that much at least of the ship's hull has been obscured by the apparent curvature of the earth from the vantage point near the high tide elevation. Secondly, while the height of the ship in the two views appears noticeably different, nonetheless, their LENGTH is precisely the SAME. Plus, since the ship is sailing laterally, it would not have moved significantly further AWAY from shore in the time it took cloudspotter to walk up the hill 230 meters. Therefore, any difference in the appearance from one view to the other must be entirely due to the elevation of the viewer and not from the distance from the viewer to the ship.

    After sliding the bar, the compression/distortion becomes easy to spot in the original photos. That's surprising how one's perception changes after seeing through a fancy viewer.

    Consequently, whatever is lost by having "a lot less hidden" as you say, is more than made up for, by recognizing how much effect distortion has on views of ships from greater distance over large bodies of water.

    ETA: In the distance, the horizon line on the distant sea is clearly seen BEHIND the ship, appearing appearing halfway up its bow from the waterline in the second photo, whereas in the first photo the horizon line is clearly in FRONT of the ship because it covers up the lowest part of the hull where the waterline is located.

    A very informative post, and thanks as well to cloudspotter, who posted this. My only request now would be if cloudspotter could provide some additional information such as date of photos, temperature of the air (approx.) and perhaps time of day (maybe an approximation of the time between photos, too?). Temp. of water would also be helpful, but who knows what the water temp would have been a mile out to sea or whatever it was. Oh, right, how far out to sea was the ship??

    We already have the 230m walk and 25m climb from the topo map -- VERY NICE!

    I was going to post this but thought it might be off topic.

    They are two different ships.

    The press.tv picture is likely to just be a stock image. All three RSN frigates in the Al Riyadh class have the comms mast in front of the radome. The top picture does not.

    Nor is it an Al Madinah class frigate (as claimed in the article) as they are of the older style of ship design rather than the more modern slab design as shown in the bottom picture of 812 HMS Al Riyadh.

    It is most likely a frigate or destroyer from a different navy, but possibly from the same French shipyard.

    Notwithstanding that, the general point stands that given they are of similar design why is 75% of the hull below the waterline in the top picture. The only FE argument could be that the ship was sinking.

    One would think! I ran into one online who thinks that could be "a wave" covering part of the ship's hull. He's the same one who thinks you can "zoom in" with a P900 to make a ship "come back" that appears to be too far beyond the curvature. But somehow he's unable to provide any example where a zoom lens can make a ship "behind a wave" "come back" from "behind the wave." And he can't show any footage where "zooming in" can make the sun "come back" after sunset.

    I ran into another one who said he needs a helicopter to make the sun come back after it sets. I told him if just standing up wasn't enough, why not take an elevator up about 20 floors and see if that does the trick?

    That link is amazing. It shows the air currents, right? And the tiny green circle is where you were standing?
    The two photos were a mere 4 minutes apart. And the temperatures were within 2 Centigrade, about 3.6 deg.F.
    So one would expect that not much refraction would be going on, but there's significant distortion in the photo taken from the beach.

    One last thing -- what power telephoto was it you used? I would guess about 1000mm or 20x? Am I far off? That means you must have used a tripod down on the beach, so by "crouched down" you weren't kidding.

    That is set to show the temperature at the surface and wind and the green circle was my rough location. You can get other information from the site by clicking on 'earth' in the bottom left

    The lens was a 300mm, no tripod

    It does not take a huge difference, it just needs a relatively steep gradient. So a small difference over a small height. 2 degrees C over 100 feet is plenty to play with

    Here's one I did over the weekend.
    DSCN8224-ping-pong.
    Metabunk 2018-06-26 08-02-18.
    39° 14’ 21.564, -119° 56’ 51.672 (incline Beach), looking west past the Crystal Bay headland (3.2 miles) to Dollar Point (8.6 miles). Jun 24, 2018 at 12:52:25 PM, 2000mm.

    I was on the beach with feet at the waterline. One shot from crouching, one stood up, so about 2 feet and 6 feet above the water.

    Tahoe Lake is very cold (50°F?) and the day was quite hot (80°F?).

    I've aligned the photos to match the houses on the top of the Dollar Point ridge. What's most significant here is that there's not a lot of difference in what is visible, but it's just compressed (or in some cases expanded) more in the low shot.

    I can see the "bigger/smaller" effect you're talking about. The orange rectangle is just below a narrow band which is about 1/2 inch tall running all the way across the photo starting 1/4 inch above the water line to 3/4 inch above. The green rectangle covers the left half of a white blotch. The top edge of the band splits that blotch in half lengthwise such that the bottom half swells bigger in the 2 feet photo and the top half shrinks smaller. Covering the top of the photo above the band and the lower part of the photo below the band allows you to see only the band that swells in the 2 feet photo.

    These bands are not exact, but have wavy edges so it's hard to describe them with straight lines. Some parts are higher up on the photo and some parts are lower down. If you could draw contour lines between them the pattern would look something like camouflage. They're small zones that grow and shrink alternately - the areas that are bigger in the 2 feet photo are smaller in the 6 feet photo. The ones that are smaller in the 2 feet photo are bigger in the 6 feet photo. There's a kind of tension between them fighting for space in the photo.

    There is another zone that is (generally) bigger in the 2 feet elevation photo, which runs (approximately) across the whole picture from left to right; it's a 1-inch tall (wavy) band from about 3/4 inch down from the top to (about) 1-3/4 inches down. If you hold one sheet of paper covering the top 3/4 inch of the photo and another one covering the bottom of the picture from 1-3/4 inches down from the top and lower, you can see the exposed 1 inch band swell in size for the 2 feet photo.

    Another 1-inch high band starting roughly 2 inches down to around 3 inches down. I'm surprised that covering the rest of the photo is so helpful in being able to see the bands. By blocking out the distraction it's a lot easier to pay attention to the 1-inch high bands. The bands lie like layers that you're looking through sideways.

    They are the results of layers, but don't exactly map onto layers. It's the resultant light paths.

    Here's a simulation of a 8 mile view over cold water:
    Metabunk 2018-06-26 12-02-27.

    The side view is showing light rays compressed x1000. They bend towards the denser air, which near the bottom means towards the water, which raises up both the horizon and the things beyond the horizon, and creates the low down compression. Then there's a bit where the cooling makes the rays bend up slightly (giving the expansion). All will just about 3°C temperature difference.

    hello, i dont think this has been answered.

    I love the Flat Earth especially the funny Memes.
    It encourages people to think and thats always a good thing.

    With the OPs experiments showing the curve.
    Shouldnt the Ship be slightly tilted away from you ?
    rather than appearing to look exactly the same as if it was much closer ?
    As it goes over the curve to remain upright shouldnt it tilt ?

    Shouldnt those Buildings also be kind of facing upwards slightly ?
     
  25. Mick West

    Mick West Administrator Staff Member

    It's both. Things ARE slightly tilted away, AND they appear to look exactly the same (tilt). The reason being that they are not tilted very much. The curve of the Earth is about 1.5° every 100 miles. So something 10 miles away will only be tilted away by 0.15 degrees. This is too small to make a visible difference.

    In addition, the tilt always makes it lean away from you, the observer.

    So even if you were able to notice such a weak tilt between two buildings when looking "from the side" (perpendicular to the tilt direction), this is virtually impossible when looking in the direction of the tilt.

    Look at the famous leaning tower of Pisa from the direction where it is leaning away from you and it will appear straight.
