notes "The problem of space travel" Herman Noordung
Preface Asteroids and artificial satelites have own speed and motion, possible to use this system for planning long travels(bases, pit-stops) Main fields of research while travelling: materials science, zero-gravity studies(also physical and chemical reaction with non-air space) Knowledge of mathematical,physical,technical 3 Most critical obstacle - gravity *Newton’s law of gravity For escape need F(escape) > F(gravity) *force of gravity of earth in theory will be in all points of the space(but sure very small if far) 4 Law of inertia with centrifugal force is important( objects in space moves in ellipses, circles) Event in the surface of the Earth we have centrifugal force For every killogram of spaceship possible to calc needed energy and velocity for ascent *All object have gravitational force for attraction - if spaceship can be like a black hole then space will move to spaceship, i mean spaceship not must moving ownself but what if space will be moving to the spaces...
