I am an agent in my environment, which is the entire universe (spacetime). My environment changes through time, which helps me orient myself in my environment. I can take action to change the environment. I can never know everything about the environment, instead a make a best guess based on my current state and trajectory.
A Glass of Wine
“The whole universe fits into a glass of wine.”
If we split nature up into pieces to make discussion easier, nature does not know it! I don’t live in the world of physics, or the world of politics, I live in the world, the entire universe, all at the same time. Everything is happening everywhere all at once, in this moment.
