It’s just us, as far as I know
The planets, or whatever they actually are, are not the same as the ground we are standing on
I can’t verify that so I don’t bother talking about that when I’m posting FE stuff
I start with the formula for calculating curvature
Earthcurvature.com
Do you live near a large body of water? You COULD do it over land but I would then recommend you test in a few places to almost entirely rule out the possibility that all of your large parcels of land happened to coincidentally be perfectly flat, however unlikely that may be
Bring binoculars if you have them
On a clear day and assuming your vision is 20/20 you should be able to see at least 20/25 kms without any issue
Bring the binos to go further and really leave yourself little room for doubt
You want to do this over water because we know water finds and maintains its level
No one denies this obvious truth about water maintaining its level
What you want to do is scan across the water or up the coastline to the most distant landmark/building you can spot
Pay attention to what you’re seeing. Notice how you’re seeing not only 100% of the distant landmark but also even the ground/shoreline running up to it
Hit google maps on a pc and right click your starting point, measure distance from here, and then right click again at your distant landmark(s)
It will give you an accurate distance and then you go to earthcurvature.com to enter in the distance and calculate how much curve there should be
20kms is about 95ft of drop
25kms is about 150ft of drop
But you’re looking at 100% of the distant landmark
Why isn’t it blocked by the earth itself?
We have examples much further than this but I don’t like linking YouTube videos when it’s much better to go out and do for yourself so that your own eyes can show you the Truth
Mentioning that we have navy vessels than can target an enemy ship 100 miles away by pointing a laser at them
At 100 miles there should be like 6,600ft of drop
Lighthouses impossibly in view, etc
Try it out, sometime!
