The shape of time

I thought I’d posted about this before, but I’ve always been intrigued by the idea of the [“B-Theory” of time](https://en.wikipedia.org/wiki/B-theory_of_time), and [world lines](https://en.wikipedia.org/wiki/World_line), and the possibility of our actions in the present forming something visible outside of time. So here’s a post that includes all those words that I can add to when I find new stuff.

• The Growing Block universe is another formulation: “The present is an objective property, to be compared with a moving spotlight. By the passage of time more of the world comes into being; therefore, the block universe is said to be growing. The growth of the block is supposed to happen in the present, a very thin slice of spacetime, where more of spacetime is continually coming into being.”
