Make your own solar systems and set them in motion here... www.gravitation3d.com Originally shared by Brian Koberlein Accentuate the Negative There’s news on the web that cosmologists have proven the existence of negative mass. The news is based upon an article that recently appeared on the preprint arxiv, and has not yet been peer reviewed. The article in no way proves the existence of negative mass, but rather demonstrates the theoretical possibility of a form of negative mass within general relativity.
