Are "flat-earthers" an actual thing?

It is Memorial Day Weekend and it's time school you globetards some more.

Bodies of water don't curve. Show me an experiment that shows bodies of water curving. If you believe in science, then the scientific method calls for experimentation to back up your beliefs.

Experiment: Take a camera on a clear winter day, and record a ship sailing away, on a large body of water, say Lake Superior.Expected result on a globe earth: If the surface of the water is curved, the ship will appear to "sink" below the horizon.Expected result on a flat earth: If large bodies of water remain flat, all parts of the ship, top and bottom, will be equally visible.https://www.youtube.com/watch?v=T874RMncnAQ

Again, this experiment proved a flat surface. Show me an experiment that proves that water curves.

The fact that you can reacquire the boat with a telescope or binoculars disproves a curve. Oceans don't bend into a sphere, YOU KNOW THIS.

Spirit level test on an airplane experiment . Where's the curve?

The video clearly shows we only acquire the very top of the ship, a plain observation that cannot be explained by a flat earth. Add this to the list of many plain observations that must be ignored, or in this case, interpreted in contradiction to what is plainly obvious, in order to develop and maintain a faith in a flat earth.If it is a Royal Carribean Cruise ship, it can receive high speed, low latency internet service, not from land towers, or undersea cables, or high altitude balloons, but from a constellation of O3B satellites orbiting at 5000 miles:https://www.o3bnetworks.com/royal-caribbean-leaves-other-cruise-lines-internet-in-its-wake/Experiment: Board a Royal Carribean cruise ship. Tools needed: Wifi ready laptop, and high powered binoculars or telescope, and a GPS receiver. With the binoculars, observe how quickly the land disappears "below the horizon", and note when it is no longer acquirable with the highest power telescope and binoculars. Note your position with a GPS receiver in order to calculate your distance from land. With the laptop, simply attempt to watch "youtube" flat-earth scientist videos. Consumer low latency broadband internet on a ship far from land towers would be impossible on a flat earth without satellites. For added bonus, measure your "ping" with a tool or a site like "www.speedtest.net". For more bonus points, record everything on video, and upload the video to "youtube" while you are still on the ship.What I know doesn't matter as much as what I can plainly observe. What I know is that Newton's Law of Gravity predicts how and why water on earth will conform to the shape of a sphere. Even Aristotle knew, 2000 years before Newton proposed his Law of Gravity, that:"Every portion of the Earth tends toward the centre until by compression and convergence they form a sphere. (De caelo, 297a9–21)"The flat earth followers are trying to set back science to some 500 years before the birth of Christ.

The curve is 30000ft below.A spherical earth model with the downward force of gravity always pointing to the center of the spherical earth, predicts the same thing: 1) the force due to gravity continuously "corrects" the altitude of the plane, balanced by the upward lift from the air, without the pilot having to dip the nose down, and 2) the bubble will remain in the center of the spirit level, as the plane remains perpendicular to the direction of gravity pointing to the center of the spherical earth.

I think if flat earthers ask nicely Trump will join your cause. Especially if he sees financial gain for himself and family.

I'm just going to stop you right there. The US Navy manual targeted laser fires as a straight beam up to 60 miles over water. Please explain away that, globetard.

Instead of spending your energy trolling, prove a globe by 360 degrees north to south navigation.

Can you explain how the seasons work on a flat model? How about extreme variables in climate in areas that would appear to have the same sun exposure on the flat model?

Watch these two videos for an explanation.

Please don't ever procreate. In fact, chop off your penis right now just to be sure.

You should probably watch these videos before you post them to defend your position. If that's how you explain the seasons and climate, this conversation is over. I expected more from you.

These kids are retarded.

I guess you stopped me and changed the subject, because you found yourself unable to address the many plain observations that anyone can make, that contradict flat earth theories, preferring to continue ignoring them and move the goalposts.To explain away your alleged "straight laser beam at 60 miles" I would need more details, to point out whatever the flat earth "expert" got wrong, such as the altitude of the laser source, and the targeted object, and the local atmospheric conditions. I don't claim you got anything wrong, because I know you are just parroting what you find.Try to give me as many details as you can about this specific long range laser targeting event, without directing me to an hour long "youtube" video.Without such specific details about this alleged long range laser targeting event, I can offer some initial likely explanations:- The US Navy actually did not target a laser beam 60 miles away over the water- or, the US Navy did, but they targeted an airborne object- or, the US Navy did, but the sources was airborne- or, the US Navy did not use a laser, but used radar- and, even laser is not immune to refraction by the atmosphere

Wrong again, Major. The NATO Sea Sparrow surface missile system as explained by an active duty US Navy missile instructor. See reference section for details.

* Typically it is an 8 missile launcher from a ship

* Ship uses gyroscopes to stabilize & works on flat/planar geometry only

* Fire control paints a 2 inch beam via direct line of site at a target from a ship

* This 2 inch beam is not bounced off the atmosphere, again it is direct line of sight

* Target reflects the signal

* Targets are tracked up to 50 nautical miles away (1 nautical mile = 1.15078 miles)

* Infrared devices don't lie and do not refract- if you see the object, it's there. Mirages do not show up. Another nail in the globe coffin.

* No curvature of earth nor Coriolis effect taken into account

* According to the globe curve table (see reference section) a 50 nautical mile target would fall 2,207 ft (8" x 57.539 x 57.539) /12"

* The globe model completely falls apart here- direct line of sight only

The military has no training program for the curvature of the Earth. This is all you need for flat Earth. Checkmate. You do not win wars with false and inaccurate telemetry.

Oh what a tangled web you weave when it's only you that you deceive.I'm not "Major" -- I'm "Ground Control".You said "laser beam" before. Now we can all see that that was wrong. Now, for some odd reason, you mention "infrared" doesn't refract. While I won't argue against that, you are wrong again -- the Sea Sparrow uses radar, not laser, and not infrared. This looks like your own mistake as I could not find the Navy instructor saying laser or infrared.Conventional radar is subject to line of sight limitations -- that's why some planes can fly "under the radar" to avoid being detected. So conventional radar is typically only used from airplanes, or to track airplanes, not flying under the radar.For longer range ship to ship, or surface to surface tracking, there are other "over the horizon" radar techniques to go beyond line of sight limitations. One is bouncing signals off the ionosphere. Another is using even lower X-band "longwave" frequencies that have the property of being able to follow the curvature of the earth. These "longwave" frequencies are especially effective over water, and especially effective at tracking ships at 50 nmi, albeit with less accuracy due to the lower frequencies and longer wavelengths.Sea Sparrow missiles use a "semi active radar homing" technique for guidance, using the active radar signal from the ship, and passively detecting the radar echo off the target, and correcting its course continuously in flight -- this inherently overcomes and corrects for any Coriolis (and other) effects, whether up, down, left or right. This technique becomes more accurate as the missile gets closer to its target.(Your nails in the coffin are made of straw).Ships use planar geometry on flat maps (but not the flat earth map) -- the curvature of the earth is taken into account when projecting a curved surface onto a flat map. It is this distortion onto a flat map that enables the practical use of planar geometry.Ship gyroscopes use local attitude disturbances as inputs to counter-act roll, and keep the down side of the ship pointing down (in the same direction as the downward force of gravity). They don't need to be aware of a globe earth -- they only need to be aware of which way is down.The US Navy missile instructor is probably correct that he doesn't have to learn, or teach, or correct for Coriolis or globe earth -- it's already done for him in the software algorithms that drives his displays, and the feedback algorithms that guide missiles. Scientists and mathemeticians have already done the corrections so Navy personnel don't have to. It's not checkmate -- you missed a couple moves. You don't win wars with Navy personnel doing calculations in combat.Your flat earth arguments are falling flat.

As a bystander who has read the entire thread, the globe people haven't even presented an argument

People have traveled completely AROUND the globe that's all anyone needs.

The only people that need to prove something are flat-earthers, because facts (undeniable truth) say the earth is round, globers(anyone with a brain) don't need to prove anything.
