Some arguments sound decent, Some arguments are just disproofing flat earth.
The gyroscope effect is a strong point for the flat earth theory.
The airplaine flight paths are one of the weakest and point more toward a globe model.
If i take off at Johannesburg and fly to Dubai, i fly at around a heading of 45 degrees.
Then when i take off at Dubai and continue at a 45 heading, no way i end up in Perth.
I will have to fly at around a 125 degree heading.

I think this world is just a simulation, It would explain the mandela effect also.
