Mirrored from mitchell fromAustralia's YT channel, from <a href="https://www.youtube.com/watch?v=F4h9Y5lqn5w&t=31" target="_blank" rel="nofollow">https://www.youtube.com/watch?v=F4h9Y5lqn5w&t=31</a>.<br />If you believe you live on a globe with radius 3959 miles, then you have a set measurement to your horizon limit, the geographical physical edge for boats to go over.<br /><br />This video absolutely destroys that, as we can see the horizon far beyond 9.41 miles from only 1 foot observer height!
