The Euclidean path integral usually has no physical meaning (unless you really are interested in non-relativistic Euclidean physics, but then why would you be thinking about Lorentzian integrals at all?). The Euclidean formulation is "easier" since integrals involving real exponential factors like $\mathrm{e}^ ...
Aug 15, 2023 · Euclidean space can have as many dimensions as you want, as long as there is a finite number of them, and they still obey Euclidean rules. We do not want to bore you with mathematical definitions of what is a space and what makes the Euclidean space unique, since that would be too complicated to explain in a simple distance calculator.
