Where is the Horizon on a Flat Earth? @icansciencethat

Uploaded January 2019 | Updated September 2026, 1 week ago

Does the Horizon REALLY rise to eye level on a flat Earth?
I mean, if the Earth were flat, where should we expect to find the horizon?

@0:20 Antonio Subirats proposes a horizon tube test
@1:08 The math behind the horizon on a flat Earth
@2:02 The equation for the horizon drop on a flat Earth
@2:36 The distance to the horizon depends on where you are and which way you look
@3:59 How big is the flat Earth?
@4:16 Where was Critical Think when he made his observation?
@5:53 Calculating the estimates for drop angle in the Critical Think observation (spoiler alert: it's really small)
@6:54 Checking some other locations/altitudes
@8:36 Can we SEE this horizon drop (spoiler alert: not really)
@9:42 But you can't see 6800 km away!
@10:30 Where is the horizon if you can't see that far?
@11:43 What distance would match the 0.3 degree observation? (spoiler alert: 18.5 km)
@12:19 Where is the REAL horizon in this observation?

$Relativity Redux (Airy, Michelson-Morley, and Michelson-Gale) The flat-Earthers are still trying to convince themselves that these classic ether experiments showed the Earth was stationary. I will highlight the original text from each experiment to show what they really said. I will show that none of these scientists ever concluded that - they didnt even mention the possibility. I will then evaluate whether or not we could interpret these results in the context of a flat, stationary Earth. SPOILER ALERT: the results are consistent with a rotating sphere. A lot of people find Einsteins Special Relativity hard to believe. These real-world experiments lead us to Relativity as the only rational explanation. jump ahead: @0:00 Intro @2:11 Movement of Earth through the ether @4:03 Airys Failure @12:53 Michelson-Morley @17:44 Rotation of Earth within the ether @18:46 Michelson-Gale @25:19 Rotating Ether on a Stationary, Flat Earth @27:29 Ether Does Not Work on a Stationary, Flat Earth @34:09 Ether Does Not Work on a Rotating, Spherical Earth in Stationary Ether @34:53 Summary (Ether Does Not Work, Earth is a Rotating Sphere, this leads us to Relativity) source material: Airys Failure: Proceedings of the Royal society of London, VOL20 (1871-1872) On a supposed alteration in the amount of Astronomical Aberration of Light, produced by the passage of Light through a considerable thickness of Refracting Medium.
