Sphere vs. plane In this article we will present in an organized way all types of arguments between the models proposed to describe the shape of the Earth, the spherical model and the flat circular model, in order to compare and try to find the model that best fits reality. From now on it will be cited as spherical or flat as appropriate. Brief description (shape, rotation, sky) Spherical: official version from the 15th to the 15th century. XV to s. XXI, planet inclined 23.4º with respect to the plane of the ecliptic. The Earth has its own rotational motion around the Sun as it moves in the Solar System (Heliocentric model), with the Moon in asynchronous motion rotating around it. Flat: Flat round motionless round Earth. The Sun and Moon rotate at the top around the Earth (Geocentric model), forming the days and nights. Celestial Vault Verifiable from Earth Magnetic field ...

Official version In 2021 for the official science the Earth is a sphere that rotates and moves along with the Moon (only satellite) and with more planets all orbiting around the Sun forming the solar system. In addition this system rotates around a larger system within the Milky Way galaxy, which is located within a supercluster of galaxies, within an observable universe in constant accelerated expansion. This system is formed by the planets listed by their proximity to the Sun as: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto. ...

Name Curiosity432 is not a random name, it comes from the combination of Curiosity + 432, however it has a why and a much deeper meaning behind it. I’ll explain it below. Curiosity Curiosity’_ (curiosity in English), is that fact that drives us all to learn, to want to know more, it is the engine of knowledge and the advancement of society. It is that natural stimulus that incites us to investigate, to try to understand the basic questions of philosophy, which are those that science tries to answer with arguments and demonstrations. ...

To answer the question «What is a numeral system?» also called system of numeration or base X (where X is a number) we will start with its definition. A numbering system is a set of symbols and generation rules that allow us to construct all valid numbers. Mathematically it is expressed as: $$N = (S, R)$$ where: N: is the numbering system under consideration. S: is the set of symbols allowed in the system. R: are the rules that tell us which numbers and which operations are valid in the system. They are classified into two main groups: positional and non-positional: ...
