Chinahand Posted December 30, 2015 Author Share Posted December 30, 2015 The red line is the diameter of the Earth!!!!!!! Gerry, look at my diagram and use your brain. It is not the diameter of the Earth and until you can understand this you will continually make a fool of yourself. Link to comment Share on other sites More sharing options...
alibaba Posted December 30, 2015 Share Posted December 30, 2015 Gerry, are you being serious? This is nearly the thickest thing i've ever seen. Link to comment Share on other sites More sharing options...
Chinahand Posted December 30, 2015 Author Share Posted December 30, 2015 Oh Gerry, Gerry, does this help you understand? Look at the red lines and think: Link to comment Share on other sites More sharing options...
Aloha Oe Posted December 30, 2015 Share Posted December 30, 2015 Chinahand, this is unrelated but can you answer a question I'm curious about. Is there always somewhere in the world where it's sunset? Would it be possible to travel in a plane (re-fueling it along the way) and to always follow the sunset? Thanks Link to comment Share on other sites More sharing options...
Chinahand Posted December 30, 2015 Author Share Posted December 30, 2015 Gerry - let's try this. Fancy doing some maths problems? 1) With a spherical earth how many earth's radii would the camera have to be away from the centre of the earth for a camera to take an image showing a disc with a diameter half that of the earth's. 2) With a spherical earth how many earth's radii would the camera have to be away from the centre of the earth for a camera to take an image showing a disc with a diameter equal to that of the earth's. Look at my diagrams and try to answer them. Do give it a real try. Answers on a postcard. Link to comment Share on other sites More sharing options...
alibaba Posted December 30, 2015 Share Posted December 30, 2015 Chinahand, have you ever seen the video of Mark Kermode reviewing Transformers? This is you talking to Gerry http://www.bbc.co.uk/blogs/markkermode/2009/06/transformers_190609.html Link to comment Share on other sites More sharing options...
Aloha Oe Posted December 30, 2015 Share Posted December 30, 2015 Also, a question for Gerry: how do you explain Sir Ranulph Fiennes' pole to pole circumnavigation of the globe? Thanks. Link to comment Share on other sites More sharing options...
gerrydandridge Posted December 30, 2015 Share Posted December 30, 2015 Chinahand: The effect your diagrams mention would not have anywhere near the level of this discrepancy seen, once the whole ball is in view, do it with a Tennis ball. Link to comment Share on other sites More sharing options...
Chinahand Posted December 30, 2015 Author Share Posted December 30, 2015 Gerry, you are wrong about this. Should we add another maths problem to the list. 1) With a spherical earth how many earth's radii would the camera have to be away from the centre of the earth for a camera to take an image showing a disc with a diameter one tenth that of the earth's. Please do the maths and actually work out the answer, it will help you understand these issues. Or are you incapable of doing them? Link to comment Share on other sites More sharing options...

gerrydandridge Posted December 30, 2015 Share Posted December 30, 2015 Are you saying that If I were to get into a spaceship and travel up I could reach the correct height to see empty space all around the earth, whilst just showing 1/10th of the diameter of the earth.?

Chinahand Posted December 30, 2015 Author Share Posted December 30, 2015 @ dilligaf, Mainly because it isn't entirely hopeless. The main problem is the world view continual tries to rationalize away the evidence I present, but it does seem possible to present the evidence in a way Gerry et al can't simply dismiss. They have to engage with it. Plus it is fun to try to think ways to explain these ideas so that Gerry et al at least understand them rather than just accept the anti-knowledge spewed out via Youtube etc. Link to comment Share on other sites More sharing options...

Why don't you work out the angular field of view in each case and compare it with various camera formats - a format 1 28mm camera lens has a field of view of 65.5 degrees. That is a pretty conventional lens without much distortion - can you work out: 1) what altitude it would be able to give you a photo of the full disc? 2) what the diameter of the disc will be compared to the Earth's radius? Gerry, being able to answer these questions will help you a lot in improving your understanding of the world. Please do give it a go. I wonder if Wrighty would join in explaining the maths?

Chinahand Posted December 30, 2015 Author Share Posted December 30, 2015 Thinking about it 28mm is probably too narrow a field of view, plus the 2012 Blue Marble image is a composite from the VIIRS Imagery Data on the Suomi Satellite taken from on average 824 km up. So Gerry, if the image is taken from 824 km up what is the disc diameter? Hint the answer the diameter of the Earth is incorrect! Link to comment Share on other sites More sharing options...
gerrydandridge Posted December 30, 2015 Share Posted December 30, 2015 It is not a single shot of the earth from 824 KM up, as you said it is a composite, which make's the situation worse, I assume the satellite has orbited the planet? To try and get a shot of earth with space all around from a height of 824 km, your field of view would surely be filled with a rectangular looking planet! To do so would mean you would have to have a massive angle of view, Link to comment Share on other sites More sharing options...
