The idea that the Earth is flat has been thoroughly debunked and disproven through centuries of scientific observation, exploration, and evidence. The overwhelming scientific consensus is that the Earth is an oblate spheroid, meaning it is roughly spherical but slightly flattened at the poles and bulging at the equator.
Here are some key pieces of evidence that demonstrate the Earth's shape:
Gravity:
- Gravity pulls objects toward the centre of mass. The distribution of mass in a spherical Earth results in a gravitational force that is consistent with observations of gravity's effects on objects and bodies worldwide.
Photos from Space:
- Images of the Earth taken from space, including those from satellites and astronauts on the International Space Station, clearly show a spherical Earth. These images provide a direct visual confirmation of Earth's shape.
Circumnavigation:
- Traveling around the world in any direction eventually brings you back to your starting point. This is only possible if the Earth is a closed, spherical shape.
Ships on the Horizon:
- Observations of ships disappearing hull-first over the horizon provide evidence of the Earth's curvature. As a ship moves away, the curvature of the Earth makes the bottom part of the ship disappear before the top.
Flight Paths:
- Airplane flight paths are calculated based on the curvature of the Earth. Direct flights between two points on a flat Earth model would not align with actual flight paths observed in reality.
Eratosthenes' Experiment:
- In ancient Greece, Eratosthenes measured the angle of the sun's rays at two different locations and used the difference to calculate the Earth's circumference. His calculations were remarkably accurate and supported a spherical Earth.
Gravity's Direction:
- The direction of gravity varies slightly around the Earth due to its spherical shape. This variation has been measured and confirmed by scientific instruments.
Satellite Orbits:
- The orbits of satellites around the Earth are consistent with the gravitational forces exerted by a spherical object.
Time Zones:
- Time zones exist because different parts of the Earth experience daylight at different times. This can only be explained by a spherical Earth rotating on its axis.
The evidence supporting a spherical Earth is extensive and comes from various scientific disciplines, including astronomy, physics, and geophysics. The idea of a flat Earth has been debunked by centuries of scientific knowledge and observation. It is important to rely on evidence-based scientific understanding when exploring questions about the nature of our planet.
