Speaking of laws....
Big Al seems to have gotten it right....
Einstein's Theory of General Relativity
has been validated on a Galactic Scale
,
as reported by Maya Miller
at Scientific American
.
General relativity thus, using Miller's language,
correctly describes " gravity at cosmological scales
".
As Miller writes:
" The results also indirectly support the theory’s validity
in the face of dark matter, dark energy
and other cosmological curveballs.
