General Relativity has been the main theme running through
the discussions I enjoyed in the previous PF version.
Cosmology issues, removal of the big bang singularity (loop quantum cosmology LQC), dark energy (cosmological constant), the limits of the observable universe, the CMB, redshift distance relations, the discovery that quantizing GR provides an explanation for inflation (incorporating inflation into LQC is another recent result),
playing around with the Friedmann equations, the recent consensus in cosmology based on COBE, HST, WMAP, and
discussion of black hole phenomena (holes are at home in GR)
The threads I've most enjoyed and the questions from other PF posters I've found most thought-provoking have all centered around GR (quantizing it, applying it to cosmology, thinking about the universe and its beginnings--- discussing what we can tell about it from observations, and so on.
Nothing else on the board is as good a fit, as far as I can see.
So for starters I guess I will hang out here. And see what happens.
The old board which had "Theoretical Physics" as a forum
and "Astronomy and Cosmology" as a forum seemed a
reasonable balance between generality and specialization----the present listing is a bit more like the college course catalog and
may be a bit numbing/sterilizing to some. But this may work out
all the same, who knows. There has to be a place for cross-fertilization and General Relativity Cum Cosmology might be a good venue
We'll give it a try
edit: "incorporating" added in line with Loop's point in the next post
