CHAPTER

The WIMP Miracle

There's no reason why in all the possible laws of physics all the particles out there have to be easily noticeable to you, that's just not how the universe is set up. A particle physicist can come up with plausible models for particles that would be cold, dark, etc. and also have the right relic abundance. WIMPs are weakly interacting massive particles. They interact by electromagnetism or some other force but it doesn't matter if they're electromagnetist nor anti-magnetic. The strength of the interactions you need for a cold, dark,. relic particle to have the right abundance has been identified as basically the interaction strength of the weak interactions of particle physics.
