Dark matter is a mysterious substance that has evaded all of our attempts at directly detecting it in our experiments on Earth. Dark matter is an important ingredient of the Universe’s evolution as it is the foundation upon which galaxies form – without it we would not exist in the solar system we find ourselves…Continue Reading How to Use Asteroids to Look for Dark Matter
The Standard Model of Particle Physics (SM) has been tremendously successful in describing how the known particles interact with one another, whether it be how charged particles interact or how the fundamental particles obtain mass. Despite its successes, there are still a number of phenomena that have yet to be explained within the SM,…Continue Reading Emergent Solution to the Strong CP Problem
Self-Interacting Dark Matter (SIDM) posits that dark matter particles interact with each other. In contrast, the Cold Dark Matter (CDM) paradigm states that dark matter particles do not experience collisions. SIDM was theorized to address problems on small scales, like the density profiles of dwarf galaxies being too dense in their cores with a CDM…Continue Reading Self-Interacting Dark Matter Solves the Diversity Problem in Galactic Rotation Curves
