Fact-Check Results:
This claim is false. The Earth is not flat; it is an oblate spheroid, meaning it is nearly spherical but slightly flattened at the poles and bulging at the equator. This is confirmed by centuries of scientific observations, satellite imagery, and direct measurements. You can verify this yourself by observing the curvature of the Earth’s horizon, tracking time zones, or even watching ships disappear hull-first over the horizon.
For a simple experiment, use a laser and a flat surface over a long distance—you’ll see the laser beam’s path doesn’t remain level due to Earth’s curvature.
