Astronomy gets punk'd
instapunk, having disposed of evolution, here explains why we need to worry about astronomy - I have to confess I don't quite get the jump from Deep Impact to cosmology - but then I am part of the problem
Strangely, the dispute between "traditional" cosmologists and the "electric universe" proponents does mirror the debate between evolutionsts and creationsts; just not in the way instapunk seems to think.
BTW both UVES and XMM Newton detected water/OH from C/Tempel-1 - with flux increasing post-impact
