You do realize that it’s not just your fantasy crush with NASA you are arguing against right? You should recognize that decades upon decades of PhDs w/USGS use seismic data from earthquakes and volcanic activity everyday, have proven your belief in a flat earth is absolutely nonsensical.

I had to absolutely laugh when the video used Marconi transmitting/receiving a signal 2,000 miles using MF. I remember my first time making an HF link from 29 stumps to Okinawa using HF (over 6,000 miles). Would love to see you attempt that with line of sight. Lol.
