Moerdehai Milgrom sets out to Modify Newton's Laws
Milgrom is a Professor of Condensed Matter Physic at the Weizmen Institute in Israel.
He theoriszes tht there is dark matter in the universe.
He expected stars at the center of a galatic circle of orbit to go faster than stars at the outside of the circle and that panned out according to Newton's Law. However, the
In checking Newton's Law with the solar system, he found it applies, but in checking it with the galaxies , it did not. Rotational curves for stars do not fall ; they flatten.Also, the middles and the outside stars orbit at the same speed.
Migrowm found it necessary to modify Newton's Law by adding a new constatn (a to the zero power) and Newton's formula, F=ma is transformed to F=ma(squared)/(a to the zero power).the new constant can take one froma restinng place to the speed of light!
When he used this new equation , the flatness of the outer distances was predictable.
What do you think ? The article btw is interesting because you follow the working path of a scinetist and you realise how much knwoledge we are still constructing as people about the nature of the galaxy.
