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

What to do in physics when “everything else fails”

10. Subtract Infinity 9. Add heavy fermions 8. Set all fermion masses to zero 7. Invent another symmetry 6. Throw it on the lattice 5. Blame it on the Planck scale 4. Recall the success of the SM 3. Invoke the Anthropic Principle 2. Wave hands a lot, speak with a strong accent 1. Manipulate … Continue reading What to do in physics when “everything else fails”
