Hungarians belong to the Uralic-speaking peoples. There are an estimated 14.2-14.5 million ethnic Hungarians and their descendants worldwide, of whom 9.6 million live in today's Hungary

    I would like to see the demo with real balls and known diameter distances from surface to illustrate this point rather than CGI photography. Mark up the ball in circular surface area percentages 10%,20,30, 40, 50, 60% is all you'll have to go. Then move the camera one diameter at a time from the surface of the ball and show the markings of the circles in the view. I'm pretty sure that you are gonna find that after just a few diameters you can see 50% of the surface but never more. Problem is that satellites don't orbit in terms of diameters, it's either low earth orbit 100-600miles or geosynchronous at 22,000 or sis lunar orbit at 250,000 or La Grange point 1 at 1,000,000 miles. The discrepancies between these orbit sizes are orders of magnitude, not geometrical in nature as NASA would have you believe.

      You’re delusional, you simply want to think NASA is lying, even though there is NO REASON TO. Flat earth was originally just a joke, a MEME.
      But brainless shits like you just decided to believe it even though no one told you to.

      Instead of trying to find “”””evidence “””” that the earth is flat and that NASA is hiding shit. Just use your GOD DAMN BRAIN

    In other words you can't tell the Earth is a globe from a satellite photo since the camera and the altitude obstruct and obscure the actual curvature and the real horizon. So if at low altitude we know the picture is distorted, how do we know it is not distorted at high altitude? Every justification you give for showing real relations between the horizon and globe size vs altitude and camera lensing work against you if you don't first assume the Earth is a globe and you know the size of it. You should be able to do the opposite, determine the size of the Earth from the known altitude and camera zoom without assuming it is a globe or knowing it is already 24,000 miles in circumference. This is all circumstantial based upon the "known" distances of satellites that are put into orbit by military, and space programs as propaganda. You have to first assume you know these satellites are up there and just trust that they are in the locations that are claimed. If you don't have a multi-million dollar telescope computer and software for tracking these you aren't even gonna be able to verify what you are looking at.

      You have to still rely on the assumption the Earth is a sphere to begin with and the sun is distant at 93,000,000 miles no matter how you cut it. This is not proof of the circumference of the Earth as you purport. If the Earth happened to be a disk your Erasthothenes experiment falls apart. If the sun happened to be closer your experiment falls apart. All experiments to determine the distance to the sun are dependent upon the Erasthothenes experiment. All experiments trying to determine the shape of the Earth turn up flat and motionless. Aieries Failure, Michaelson-Morley, Sagnac.
      If you begin with the assumption the Earth is a disk or a plane, you would have to discount the theory of gravity, which most people can't get past. Unfortunately, gravity is just a theory or law, not supported by any evidence. Cavendish showed that electrical charge and gravitation are mutually interchangeable as theories if you consider aggregate charge on matter acting as a dipole to attract/repel matter on a large scale. Birkeland currents prove this out, along with the solar wind and the "fact" that the sun is not a fusion furnace, but a metallic hydrogen anode in the galactic circuit.

      You can determine the circumference of Earth by simply putting a stick in the ground on a sunny day and having a friend a considerable distance away from you doing the same thing. Make sure the stick and the ground make a right angle, and then you take a piece of string from the top of the stick to the tip of the shadow, and measure the angle the stick and string make, and then compare that angle to your friends angle. If you multiply 360 degrees by the distance between you and your friend, and the divide all that by the difference in that angle you measure, the answer will be the circumference of the Earth. People figured this simple geometry out a couple thousand years ago.

      Flat Earthers would argue that the sun is simply closer than the 93 million miles science "claims" (and proves by the way), and the difference in angle is the result in the difference in the angle at which the sun shines on those sticks. The problem is, there is no distance the sun can be placed that is consistent with all observations. It is only self-consistent if you put the sun at 3,000 miles - and only use the example of the difference in that angle being 45 degrees from 3,000 miles away. This is why flat Earthers place the sun at 3,000 miles. The problem is that this only works in this one scenario. You get a different distance to the sun in every other scenario. The absolute oblivion it takes is astonishing.

      For example, if someone were 5,000 miles apart, the difference in those angles would be about 75 degrees. Doing literally the exact same math flat Earthers use to arbitrarily place the sun 3,000 above a flat plane, you now get 1,340 miles as the distance above the plane for the sun. You can keep going, and you will get a different answer each time. The reason it is not self-consistent is because the premise of the calculation is that the Earth is flat. There is no distance you can place the sun that is consistent with observable reality - because the Earth is not flat.

      On the flip side, when you consider that the difference in angle is due to the fact that people separated on Earth are actually separated by an angle - because the Earth is a sphere, and that difference in angle at which they observe the sun corresponds perfectly and 100% consistently in ALL scenarios to the difference in their angle of separation along the curved arc of the Earth's surface - you realize that the globe model is the only model that is both self-consistent and consistent with observable reality in 100% of applications. The flat Earth model and its corresponding geometry only work in a single scenario - the one scenario for which they place the sun at 3,000 miles using a calculation that already assumes the Earth is flat. It's circular nonsense, and it literally falls apart in literally every other scenario. It's nonsense. You're not enlightened. You're not special. You're just a patent moron.

      We did? Back in the 1960's i believe. We're actually preparing to go to the moon. Space exploration is time consuming and costly. It's better to take time on a project to make it work than have a rushed product that might not work. Try staying updated to SpaceX. If you can try actually going to the launch sites and spectate the launches.

      African Adventures It would be great if Vsauce did that, because its a complicated topic and Michael could probably make it pretty interesting.
      That said, here's a short try to explain: what the guy in the video is getting wrong is that the thermosphere is not in equilibrium - it has no single temperature. The supposed "temperature of the thermosphere" is actually just describing the kinetic energy of the molecules within it, but because their density is so low it is also important to take into account the electromagnetic radiation in the same zone - which, again, is not in equilibrium with the atmospheric temperature. So, to determine the temperature of the ISS you have to consider the way it absorbs and radiates energy, the atmosphere plays a very minor role.
