I've now made multiple posts on different forums which have received thousands of views and dozens of comments pointing out a dealbreaking flaw with the flat earth explanation of days and seasons.
Tldr of the flaw. Either the sun moves at a constant speed around flat earth, or its speed changes throughout the year. Neither possibility matches the observable movement of the sun.
Flat earthers have been unable to provide an explanation for how days and seasons work that fixes this flaw.
The flat earth model cannot explain days and seasons without contradicting reality. The round earth model can explain both, simply and concurrently.
This flaw concerns basic phenomena of our day to day lives. Day/night and seasons. Its a false equivalence to say things like "well globe earthers can't explain everything, like what happened before the big bang".
It is intellectually dishonest to continue believing the earth is flat due to this impossible to resolve flaw.
Forget gravity, the dome, Antarctica, the coverup etc. Flat earth is DOA because you can't even explain days and seasons.
So, flat earthers, why do you continue to believe something that you can't even explain basic parts of?
I don't know what was said in this thread but here is the real reason. Most don't believe. Only 5 or less here actually believe. A flat earth member recently came out as a troll. Others just leave. Some prominent members no longer post here. If you claim to do many flat earth experiments would you just leave? No. They lied.
One actual flat earth believer has a mental illness where they can only believe the most outlandish stuff. Cars move by engines? No. Cars move by magic fairies? Yes.
Another was just stuck in old ways, probably due to a mental illness.
Another one thinks it make them smarter and more enlighten to believe the earth is flat.
One of the "flat earthers" made a map which had Moscow at a higher latitude than Helsinki. Do you see the mental illness trend?
Other's played flat earther like playing dressup. They mostly moved to the other site.
While it was always easy to see them lie, compared to 10 years ago to a few years ago the arguments were different, in my opinion. 10 years ago they would try and make claims. With recent events they changed to only being able to deny things. Starlink satellite trail comes to mind. "They don't exist" or "are something else". It came out of necessity. Most other lies are just from the trolls. denpressure and sun is a reflection off ice dome are just troll lies. I don't even bother to debate anymore. It only took me 14 years to realize just how worthless it is to continue to destroy the troll's(and the few real flat earthers) arguments.
To add some more to answer your question.
The troll flat earthers lie to troll. Some get bored and leave but others may take their place.
The real flat earthers have no more arguments so they don't post much anymore or at all. The only real flat earther who posts is Username, but just look at the quality of their posts nowadays.
