The earth is round

The Earth is round, more precisely an oblate spheroid, which means it is mostly spherical but slightly flattened at the poles and bulging at the equator.

The reporting

What the Evidence Shows

Scientific consensus, supported by centuries of observation and modern satellite imagery, confirms that the Earth is round. Ancient Greek philosophers first deduced Earth's spherical shape through observations of stars and shadows. Modern science refines this understanding by describing Earth as an oblate spheroid due to its rotation causing a slight flattening at the poles and bulging at the equator.

This shape is confirmed by satellite images and measurements of gravity. While the Earth appears flat locally due to its large size relative to human scale, global evidence from astronomy, physics, and direct observation from space conclusively supports its roundness.
