This website relates to the theory of physics proposed by Fredrik Nygaard in the fall of 2017. This led to the publication of Universe of Particles in 2018, and Aether Physics in 2020. A third book titled the 5th Empire was also published during this time period.
Universe of Particles is a general proposal and exploration of the idea that reality may be completely explained in terms of easy to understand particles, as opposed to the complex framework known as the Standard Model.
Aether Physics goes through the proposed theory in more detail. It focuses on the core ideas of the theory without bringing in observations only incidentally related to it.
The 5th Empire is not about physics. Rather, it outlines various strategies related to investments, finances and politics that can be employed in order to free up time for the pursuit of personal interests.
