Skydivers can see the curvature of the earth
« on: October 04, 2017, 03:08:10 PM »
If the world is flat, what explanation is there for the curvature seen by skydivers?

Example:

Edit: In the last second of the video, the curve appears inverted. This actually proves that it is only because of the camera. You would have to actually skydive yourself to say for sure.

It is inverted in the last seconds because the camera goes upside down so it is consistent with a round planet. the curvature is clearly visible in this video and you can tell it is not a fish eye lens due to features on the land below and the skydivers having zero distortion. Can not wait to see FE'rs explain this in detail

I have sky dived twice and did not see any curvature. Certainly not with my eyes. You only go between 4-5km max. Hardly enough area to see far enough out that you could witness a curvature (if there is one :P)


Keep trying though. It's been fun

Agreed, not only is it not high enough, but the goPro camera used has too much barrel distortion to be useful for the tiny curve that might be there.

Lens distortion can be minimised by selecting a frame where the horizon goes through the centre of the image and preferably with the horizon as horizontal as possible.
Here are three adjacent frames that were the best that I could find:

horizon above centre (false convex curve)
     
GoPro HD skydiving footage test at Lodi Parachute Center,
horizon close to centre (no curve)
     
GoPro HD skydiving footage test at Lodi Parachute Center,
horizon below centre (concave curve)
The horizon curvature is so slight till you get to say 100,000 ft that great care is needed to observe it.

This one, taken from a flat earther's video at 121,000 ft, shows enough to be convincing:

So just watch lens distortion or these flat earthers will be down on you "like a ton of bricks".

I have to hand it to you on these things you clearly know much more than I do, good job I am not a flat Earther or I may burn you at the stake for it :)
I am trying to bring my knowledge up on these things because I am sick of these ridiculous imaginary stories harming the intellect of the next generation. It is scary that Flat Earth theory is actually making headlines these days my fear is it will influence learning a bit like the churches of old did and set back actual research and learning and push up towards another dark age where learning was frowned upon. We have enough issues with science in schools with religion wanting creationism taught to children like a fact nevermind FE

In this instance I accept I was wrong because rabinoz explained it to me and I accept his reasoning, I have no problem admitting when I am wrong. Your response was not helpful in making me realize my error due to the last sentence, Up till that point your reply was fine and would have made me reevaluate my reply so it became counter productive.

OK. My apologies.

Rabinoz is certainly a globe earth guru and presents his arguments very well and thoroughly backed up.

Sometimes I get bored and shitpost. I usually try to make them obvious so everyone knows when I'm talking crap or when I'm serious.

I'm a globe earther too and like to have a bit of fun now and then trying to put myself in the shoes of the other side. Maybe it confuses people. Well at least it fits with the nick name of Shifter. It can get soooo bored at work the thought experiments are interesting and keep me sane. You will find the people on this site are actually pretty good and what you read is mostly just friendly banter for shits and giggles. Try not to take anything too personally (especially in the Angry Ranting forum!) I certainly like to think nobody means anyone any real ill will here although you do get some angry noobs but they never hang around long enough. I think I used to be an 'angry noob' once too lol

Thanks, but I realise that my posts do sometimes often get too long and boring.
