If you didn’t understand it, then why have you waited this long to ask for clarification?student34 said:I do not understand the onion analogy. I understand that we can integrate many 2d onion bulbs to create a full onion. But I do not understand how that relates to this. What are we integrating in the example?
Each leaf of an onion is a sphere. So the metric of each leaf is
The full space does not inherit the metric from the leaves. An onion has spherical leaves that foliate a Euclidean space. Spacetime has Euclidean leaves that foliate a Minkowski space.
