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

Aria di Terremoto?

Le teorie popolari, si sa, spopolano laddove quelle scientifiche non arrivano. E' soprattutto la zona grigia - dove qualcosa tutto sommato abbiamo capito, ma non tutto tutto - dove si avventurano molti non esperti, che cercano di dare una spiegazione plausibile all'origine di fenomeni naturali catastrofici ma purtroppo difficilmente prevedibili come ad esempio un tempo … Continue reading Aria di Terremoto?

Why don’t we build a particle accelerator orbiting the Sun?

Disclaimer: this is a blog post, not a paper. Seriously, I'm not suggesting to build such an accelerator, but I believe that by trying to answer this question the reader can learn something about the intriguing realm of accelerator physics. The Large Hadron Collider operating at CERN is the most powerful collider ever built by … Continue reading Why don’t we build a particle accelerator orbiting the Sun?

Has Particle Physics Been Hijacked by ET?

After the two sophons arrive on Earth, their first mission is to locate the high-energy particle accelerators used by humans for physics research and hide within them. At the level of science development on Earth, the basic method for exploring the deep structure of matter is to use accelerated high-energy particles to collide with target … Continue reading Has Particle Physics Been Hijacked by ET?
