How to debunk flat Earth theory?

To debunk the flat Earth theory, you can present various logical and scientific arguments, as discussed by Jordan Harbinger and his guest Dave Farina.

1. Multiple Space Agencies: The existence of multiple independent space agencies globally makes the flat Earth narrative untenable. If it were only NASA involved, the argument of a conspiracy might seem more plausible to some, but with many countries and their respective space agencies, this becomes highly unlikely 1.

2. Staff and Budget Realities: The flat Earth theory implies a vast conspiracy involving thousands of personnel and enormous budgets to sustain a lie about the Earth’s shape. This is financially and logistically irrational. No government or entity would expend vast amounts of money to pay staff for no productive work in an age where efficiency and cost-cutting are paramount 1.

3. Historical Knowledge: The knowledge that the Earth is spherical has been established for thousands of years, predating modern space agencies and technologies. This long-standing understanding is backed by centuries of scientific observation and deduction 2.

4. Observable Scientific Evidence: Real-life observations contradict the flat Earth model. For example, the behavior of the sun and its consistent size in the sky throughout the day does not align with a flat Earth model where a sun orbits above a flat plane. The sun's path and size as observed from different locations on Earth would vary significantly if the Earth were flat 3 3.

5. Evidence from the Horizon and Physics: The curvature of the Earth is visible from higher altitudes such as seen in flights. Also, basic physics like gravity which shapes planets into spheres due to their mass, cannot be coherently explained by the flat Earth theory. Furthermore, the varied gravitational pull observed at different points on Earth directly opposes the flat Earth model 4.

By pointing to these compelling and widely verified facts and leveraging scientific consensus, you can effectively challenge and debunk the flat Earth theory.
