We all realise this is only 18-20 miles up...
The earth is ~24,000 miles around
This perspective is far too small to try to understand the actual size... This is why you think its flat, you think 20 or even 200 miles is HUGE!
The earth is in the ballpark of 126,720,000 feet around. 20k ft aint gonna be shit on that when it comes to our 6 foot tall perspective.
You cant really argue this. With those numbers (give or take a tiny amount [with the overall size of things, 100k ft is tiny], my math may be slightly off) laid out, as proven fact.
Weve been measuring the earth for quite sometime. What was it QG. Greeks, b.c. figured it out by pic related, then with numbers, calculated the size...
When you use your brain, its not that hard to comprehend... Then again, its about an 18 hour drive to Florida for me, with stops, roughly 1000 miles, driving to the moon at 60 mph would roughly take what, a bit under 6 months.. At give or take 240,000 miles away?
You have to stop, and understand the values of the numbers you are reading. 24000 is big. 240000 is quite a bit larger. Try to wrap your head around these stats.
