I have a Masters in Mechanical Engineering
After reading the experiment you came up with, i doubt it.
May I be bold enough to suggest the following?
[proceeds with suggesting an experiment]
For camera's it's perfectly possible to look straight ahead. For humains not. So simply putting 2 cameras at a certain distance away from each other isn't gonna prove anything. A better experiment:
For starters invite people from all relevant parties. So this includes REers, FEers, DETers, ... Also invite multiple media and some alternative media. Have all of the mentioned parties send at least 2 people.
For the experiment itself: Take one heck of a strong laser, put it at a certain distance above the ground (measure this distance with high accuracy). Make sure it's perfectly leveled, check this with preferably at least 2 different measuring instruments that are very precize.
Now take something (sheet of metal, cardboard, ...) and apply markers to them every 5 or so cm (again make sure they are accurate). Make sure you can put it on the ground perfectly straight up.
All of the above mentioned must be observed by all members of all invited parties. After this have 1 member of each party stay with the laser to verify that nobody tampers with it. Have the other member accompany the board to a location 7 miles 'down range'. (other members from the same party may do as they please)
Now put the thing with the markers on and put it in the beam of the laser. Check its altitude above the ground, use the markers and every other accurate tool available.
Now one last final step before crying eureka: get the height above sea level of both locations. Be exact don't use GPS as it isn't accurate enough.
Now do the math with the numbers i trust you can find out yourself what math you have to do.
Edit:
I found a better video than the previous one:
And this guy actually makes a valid point. Using 2 lasers would indeed be better. However i'd level them using 2 different devices. This way one can be even more sure that they are leveled.
end edit.
The administrators of this site, must try to find people to do this video.
Why the heck 'must' they do that?
Another edit:
This is what we have to do to prove that the earth is flat and to end all discussion.
Nope, both your and mine experiment can be explained by a phenomena FEers scientifically explain as: "Bendy light".
It is impossible to end discussion. You'll always have the ignorant and the misinformed (i'm not saying that FEers are ignorant or misinformed, i bet you there are more ignorant and misinformed REers). And they'll just keep discussion with you. And then you have those who don't care about the truth and just want to believe something. (there may or may not be some FEers that fall into this category, i'm not gonna comment on that. There definitely are REers that fall into this category.)
