When considering earth as stationary and flat, the sun must be moving on a conic trajectory . (Maybe you can remember my article “Our Earth Pond and the Tent of the Sun”). In the same way the moon, in its movement in the space/ time, has to follow a trajectory moving in the shape of a cone. And this will be the basic theme of the following consideration.

## Star speed proves gravity is wrong

## The theory

As indicated in the articleThe-paradox-of-gravity-not-respecting-the-energy-conservation-principle/ satellites are subject to a double different force, the gravitational one and the centrifugal one. This implies that the nearer a satellite is orbiting around the earth, the faster it has to move to win the bigger gravitational force and the other way round. To better describe this idea we have to introduce the concept of angular moment. This is the product of the impulse of the satellite ( **I=mxv** where** I** is the impulse**, m** is the mass of the satellite and **v** its speed) and the distance of the satellite from the Earth, **R**.

## The real value of Pi?

## The reproducible reality

Math is the key to understand and describe the universe. The question is: can we consider the opposite situation always true? I mean, is it possible to reproduce in the real world all the ideal abstractions that are possible in the math world? Read more

## Our Earth Pond and the tent of the sun.

In a previous article” SketchUp and flat Earth lesson 1 ” you were given indications about how to model a flat Earth pattern with Google Sketchup.

You will discover today how to create a component you can easily duplicate. Read more

## Polaris proves the Earth is not a globe

Polaris is a particular star. It is almost exactly over the North Pole. This position makes this star perfect to do some calculation in relation to the Earth.
