Regularization of the triple collision in the collinear three body problem

This is a work about the collision of 3 celestial bodies which are aligned in a straight line, by following Newton's Gravitational Law. There is an introduction which shows the most important items of the general N-Body Problem in order to introduce the main concepts to work on with the main problem, which is the collinear 3-Body Problem. After this, at the conclusions we will see how the dynamics work for more than 3 bodies
