Few figures in the history of technology are more controversial than Wernher von Braun, the card-carrying Nazi scientist who built, by the exploitation of thousands of slave laborers from concentration camps, the world’s first ballistic missile. Working for NASA he became a leader in the American space program, building the rocket that carried Apollo 11 up to the moon. Read more
There are still great truths to say, if we had both the courage to state them and the good disposition to accept them. Freeman Dyson
Mainstream science today is not headed the same direction of the flat earth. You could suppose a sort of secret conjuration took form in the course of the years, contrived with the aim to cover the evidence. Probably just a handful of influential men, endowed with certain personal charisma, were sufficient to build a framework that can no more be put under discussion. Scientific freedom remains an illusion. Scientists have to stay inside the limits of the established rules and only the braves are daring to challenge that implicit command.
We could say that the annual parallax of a star is the angle defined by the sun, the star and the Earth. (considering the star perpendicular to the line that unites the Sun and the Earth).
Astronomical aberration is a phenomenon that makes a star, seen in a telescope, appear in a place slightly different from the expected. Aberration has been observed in 1727 by the English astronomer James Bradley who, in the course of his surveys, noticed that stars seemed to be subject to a slight movement within a period of one sidereal year. He thought that this movement depended on the position of the star inside the celestial sphere. Read more
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.
