There a lot of talk about the idea of an Earth mass Primordial Black Hole punching through Earth and the effects of such an event. However, Planet nine is predicted to be about five Earth masses, not one.
I don't have a physics degree, but how close would Earth have to get to such an object before the Earth is within that object's Roche limit?
At a brewery, or a restaurant for that matter, aren't you there to basically recreate a product based on a recipe someone else formulated? The person tasked with creating the recipe has the opportunity to practice artistry in this scenario, but they, too, may be under business related pressure.
I'm currently listening to the Great Courses course called "Machiavelli in Context" on Audible, and his take was more that Machiavelli viewed monarchical rule as a stepping stone to a republic. In the Discourses on Livy, he gives the example of the people of the Roman Kingdom rising up to dethrone itheir king to establish the Roman Republic.
He goes on to say that, depending on the circumstances, a republic could backslide into monarchical or despotic rule, as the Roman Republic did when it transitioned into the Roman Empire.
The idea of a monarchy or a dictatorship being a stepping stone to a republic isn't something I see expressed online as much.
