I have always been fascinated with "origins": the origin of life on Earth, the origin of human beings, the origin of the Universe, and of course to fundamental particles. I reserve a sort of special place to a mathematical entity that some people regard as fundamental: prime numbers. A prime number is a whole number greater than 1 whose … Continue reading The Prime Numbers Cross: Mathematical Oddity or Hint of a Deeper Pattern?

# When Your Gravity Fails and Negativity Don’t Pull You Through: The Case for Negative-Mass Dark Matter

In early December 2018 the physicists' blogosphere went berserk because of a 2017 paper (in fact still a preprint to this date: arXiv:1712.07962) in which the author James Farnes, University of Oxford, tries to explain Dark Matter and Dark Energy with a seemingly preposterous hypothesis: the presence of a negative-mass fluid that permeates the Universe. … Continue reading When Your Gravity Fails and Negativity Don’t Pull You Through: The Case for Negative-Mass Dark Matter
