False, already debunked this elsewhere.
No, no it hasn’t.
This is a typical strategy of the mislead, and the wrong. Minimal reply, alluding to something and then trying to shift the rhetorical burden.
There is no debunk of the horizon, merely three non-explanations that are neither explained nor defended.
1.) “It’s perspective”
No attempt to explain wtf that actually means, merely a handwaving statement meant to seem like it’s explaining without actually explaining. No diagrams, no maths, nothing.
2.) “ships can be zoomed back in”
Except they can’t. It’s impossible. If the sea is in between the observer and the ship - no amount of zoom will change that. Moreover all example videos shown are merely taking a ship from being imperceptibly small to being seen - no zooming video has or will ever take a ship that has some large portion obscured to having no portion obscured.
3.) “it’s refraction”
Another meaningless handwaving explanation, that violates all demonstrable properties of refraction in the atmosphere, again proposes no model or images to justify how a horizon can appear at all - much less everywhere, all the time, ubiquitously in all weather conditions…
So no.
