Smackdown Watch

Today has been a good day for smackdowns! First up, Simon White in New Scientist, punching up his previous argument:

We need to apply a hard-nosed cost-benefit analysis to dark energy projects. We must recognise the cultural differences between high-energy physics and astronomy, and be willing to argue that astronomical discoveries – that the universe expands, chemical elements were built in stars, black holes exist, planets orbit other stars – are no less significant for humanity than clarifying the underlying nature of forces and particles.

Any large new astronomical project should be designed to push back frontiers in several areas of astronomy…

If we don’t do these things, we may lose both the creative brains and the instruments that our field needs to remain vibrant. Dark energy is a Pied Piper, luring astronomers away from their home territory to follow high-energy physicists down the path to professional extinction.

Next, Pope Benedict (via Atrios and Cynical-C), putting the hurt on those nefarious splitters:

The Vatican reiterated Tuesday that the Catholic Church is the one true church established by Jesus Christ and that other Christian denominations are defective, although they have elements of truth and sanctity.

In a brief document, “Responses to Some Questions Regarding Certain Aspects of the Doctrine of the Church,” the Vatican’s doctrinal office, with Pope Benedict XVI’s approval, reiterated controversial assertions made in its 2000 document, “Dominus Iesus,” that Christian denominations that do not have apostolic succession — the ability to trace their bishops back to Christ’s original apostles — can’t properly be called churches.

And finally, Senator Patrick Leahy, via Matthew Yglesias and a dozen other blogs:

A powerful elixir of sarcasm and high dudgeon mixed into a few sort sentences! Awesome.
