Depends on which hat you're wearing. If you're wearing an astronomical or GR hat, new particles are simple. Just add their mass, and space curves differently, and you're done. But if you're wearing a particle physics/standard model hat, new particles are a huge deal. They change all kinds of things. Some of those things that change have rather large effects on cosmology. |
