متن کاملCosmic rulers
We derive general covariant expressions for the six independent observable modes of distortion of ideal standard rulers in a perturbed Friedmann-Robertson-Walker spacetime. Our expressions are gauge invariant and valid on the full sky. These six modes are most naturally classified in terms of their rotational properties on the sphere, yielding two scalars, two vector (spin-1), and two tensor (s...

Examples include bacteriophage tails, bacterial flagellum hooks, bacterial ‘injectisome’ needles, and the thin and thick filaments of striated muscles. Such exact assembly requires explanation, because the same sub...
