Exploring abrupt climate change induced by comets and asteroids during human history

Panspermia

Cambridge scholar and cosmic life propopent dishes on the deal
The entry of microbes and viruses is discussed in an appendix in diseases from space.  Whilst large fragments like pebbles and millimetre-sized bits get heated as they enter the atmosphere at speeds of 10km/s, and many burn as meteors, smaller structures survive.  For example an atom or molecule survives and even a virus coated…
Kyle and Russ Allen snake the truth from the jaw of ignorance
The Tusk helped arrange a podcast between some dear friends this weekend and made an unexpected cameo at the end. Cambridge scholar Dr. Chandra Wickramasinghe provided a detailed explanation of the evidence for space as the principle vector for viruses, after a stupefying explanation of where we come from — and how we got…
Wickramasinghe warns of Cosmic Pandemic on November 25, 2019
On the basis of this data, there appears to be a prima facie case for expecting new viral strains to emerge over the coming months and so it would be prudent for Public Health Authorities the world over to be vigilant and prepared for any necessary action. We need hardly to be reminded that…
Tusk sends letter of protest to editor, hopes to avoid litigation
To the Editor of Space.com: I am writing to protest misinformation in your article, “No, the coronavirus didn’t come from outer space. We promise” [March 16, 2020, Space.com], and demand an immediate published retraction and apology to the subject of your article, Dr. Wickramasinghe….
Junior scientist Graham Lau plays pseudoscience card on veteran Nature author on Space.com
Dr. Wickramsinghe was kind again to share some preprint journal articles and original communications today with the Tusk. See below and earlier posts concerning Wickramasinghe et al. and Coronavirus from space. Last night, sciencey talk pup Graham Lau took a real shot at Dr. C in a terribly written article by Chelsea Gohd in Space.com…
A heterodox communication from Chandra Wickramasinghe to the Lancet
As regulars know, this is the 2nd communication this week from living scientific martyr Dr. Chanda Wickramasinghe to the Tusk, and this one is perhaps the more pressing. Chandra’s note below, shared first on the Tusk, is to the prestigious medical journal The Lancet and a technical communication concerning the increasingly global scourge of Coronavirus….
Avi Loeb and Amir Siraj poach ground long settled by Hoyle and Wickramasinghe
The Tusk has a flip-side fascination to my obsession with cosmic impact and extinctions: Life on earth and how it got here. Looking into the life story makes a nice yen to the yang of the death story. So I have been fortunate over the years to develop a digital acquaintance and enjoy occasional…
Panspermia increasingly vindicated
The Tusk is honored to maintain a digital acquaintance with distinguished Professor Chandra Wickramasinghe, who in the 1970’s with Sir Fred Hoyle established — and to my mind proved — the theory of Panspermia. We had been corresponding concerning the jaw dropping recent genetic study, when NASA announced today’s press conference. I asked Dr….
Check out this great summary paper from the irrepressible Chandra Wickramasinghe.  Wickramasinghe just keeps going and going and going — even without his side-kick Sir Fred Hoyle. Hoyle and Wickramasinghe’s decades-old contention that life evolved in space and spreads via comets is convincing to me.  Not only do they have substantial data indicating this to be…
