Only just very recently have I seen bits of video where flattards use levels to 'disprove' the globular Earth. Including taking them on overseas flights. I couldn't have imagined the fools would even bother using a tool which cannot prove nor disprove Earth's shape because both models involve a local vertical which is everywhere perpendicular to the surface. Idiots!
They would be better served by a decent gyroscope having precession eliminated (running at constant speed). Why don't they try *that*?
Because doing the experiment right would prove them wrong.
It's the same with Southern Hemisphere travel, flights between between Auckland and Buenos Aires-Ezeiza, or Sydney to Johannesburg-O. R. Tambo would take days to complete compared to how fast they are actually flown. Sailing between South Africa, Australia, New Zealand, and South America would also take far longer then advertised. Anyone that decided to sail the roaring 40's would know that the Earth was flat, if it really was, because it would take them far longer to get between destinations than it should, and I'm not talking days longer, but weeks and months longer.
Flat Earther's consistently ignore it all though.
They and all other CT'ers are great at ignoring things that don't suit them.
The biggest one is that even if you can poke holes in a current science theory, that doesn't mean that you get to just slot your different theory into its place without any scrutiny of its own. That's not how science works, and yet virtually every CT out there seems to be of the belief that if they can poke any hole in the "Official" Theory, then by default their own must be true.
No, the way to make your own theory the default is to show that not only does your theory explain all of the observed phenomena at least as well as the current one, and in an internally consistent manner, but that it also explains any holes in the current theory better too!
As of yet I have yet to see any CT'er take up this challenge. Instead when asked to put forth their own theories they switch to that they are just JAQing off, or as Daniel seems to do, claim that any attempt to get him to explain how things work under his own theory, that such is a "red herring" rather than understanding that it's how science works.
Currently I have yet to see any Flat Earther give a consistent, testable, and plausible explanation for the following things:
- Why Horizon distance varies with attitude but not optics.
- Why the sun sets from the bottom to the top.
- Why travel times between like distances on a global Earth at latitudes South, are the same as those at Latitude North
- How people all around the so-called "Southern Hemisphere" see the same stars despite being on opposite sides of a flat earth.
- Why the Southern Stars rotate clockwise about a point in the sky that corresponds to south on a compass, while the Northern Stars rotate about a different point that corresponds to North.
- Why Hurricanes and Cyclones Rotate.
- Why an anticyclone outside the Equator rotates anti-clockwise, but inside rotates clockwise.
- Why Hurricanes and Cyclones move away from the Equator.
- Why Solar Eclipse paths aren't straight on a flat Earth map.
- Why everyone on Earth sees just one side of the moon
- Why the phases of the moon predictably match the sun/moon position in a three body system
- Why lines drawn using sun angles taken simultaneously across the planet don't met up at a single point
- Why Air pressure varies in a predictable manner with altitude.
- What it is that crosses the sky at the time the ISS is predicted to be seen crossing the sky
- How NASA can fake cloud patterns seen live on the ISS streaming camera to match those of the sky being passed over
- How everyone in NZ and Australia can point their dish antenna at the same point in the sky and receive TV signals.
I am sure I can think of more too, but it'd be a good start.
