- The sphericity of the Earth is stable through the ages
read The idea of a spherical Earth ancient Greek philosophers such as Aristotle (384-322 BC),
who obtained empirical evidence following traveling to Egypt and seeing new constellations,
what became Eratosthenesin the third century BC the first person to calculate the circumference of the Earth.
Likewise, other advanced measurements were made by Muslim scholars around the 9th century CE.
Designed by a French physicist Leon Fock an experience Through which he presented a simple scientific proof of the fact that the Earth rotates on its axis,
It was a suspension of a weight of 28 kg on a wire 67 meters long to the dome of the Panthéon Church in Paris, and as the Earth rotated,
The pendulum seems to complete a complete rotation, because it tends to move in a constant direction in a vacuum under the effect of inertia,
While the earth is revolving under it.
of the highlights Evidence On the sphericity of the Earth, the phenomenon of a lunar eclipse, where the shadow of the Earth always has a circular shape,
Note that the only shape that casts a circular shadow no matter how light is shined through it is a sphere,
And no other shape will be able to cast round shadows under these varied conditions.
- Travel across or even within different time zones
According to a research paper published in 2008 in the journal Applied Opticsthe curvature of the Earth becomes somewhat visible at 35,000 feet (with a field of view >60°),
In addition to the presence of time zones In itself, evidence that the Earth is spherical, we will find that it will be night in one part of the world and day in another part.
