## And two articles in The Guardian
- The hoary old saying about extraordinary claims requiring extraordinary evidence is repeated, yet the evidence comprises some ignored as not fitting mainstream theories and some from samples studied in Cardiff University labs. The evidence is extraordinary only in the way it’s put together. No-one was concerned about stratospheric dust containing siliceous fibres until identified as extraterrestrial with silicious spines of diatoms embedded in the matrix. No-one was really concerned until the tentative identification of microdust particles as bits of cometary crust such as found on comet CG.
- No surprise that galaxy-astrophysicist Jillian Scudder failed to recognise potentially “extraordinary evidence”.
- The ESA project’s Matt Taylor declares “pure speculation”, yet he’s well aware of the published work and well aware that Rosetta studies have confirmed our concept of a cometary crust of carbonaceous-mineral aggregate. He saw our evidence of comet-like particles containing bio-fibres. Is he bound by ESA’s decision against seeking evidence of extraterrestrial life (first Guardian article) ?
- Sarah Hörst says her research horizon is the ‘origin of life on Earth’. Have discoveries of the hardiness of microorganisms carried on meteorites from Mars and space passed her by? Perhaps she's unaware of panspermia studies, showing that viable spores (and DNA) can spread between planets and, on some arguments, spread to the interstellar dust that contributes to new planetary systems?
- Monika Grady is well aware of this as a meteoriticist, so she comments more moderately: “highly unlikely”. We await her argument for saying our stratospheric dust particles are unlikely to come from a comet and/or unlikely to be representative of comet CG’s crust.
