Scientific career
FieldsAstronomy and mathematics

Nalin Chandra Wickramasinghe (born 20 January 1939) is a Sri Lankan-born British mathematician. He is currently Director of the Cardiff Centre for Astrobiology, a private company and charity.

He was a student and collaborator of Fred Hoyle. Their joint work on the infrared spectra of interstellar grains led to developing the hypothesis of panspermia. It proposes that life on Earth was 'seeded' from space rather than arising through abiogenesis on earth.

Based on the latest results of the Kepler Mission, NASA has estimated that there are approximately 144 Billion earth-like exoplanets around sun-like stars in our Milky Way Galaxy. This fact alone has caused a global change in attitude to the probable existence of extraterrestrial life - certainly microbial life and, for many, intelligent life. Not only are senior academic figures supporting this paradigm change, but a new generation of NASA scientists have now openly embraced the "search for life" . This consciousness change, supported by the media, has brought the ideas of Fred Hoyle and Chandra Wickramasinghe back into the public eye. Fellow Astrobiologists and Astrophysicists are revisiting the Panspermia hypothesis and its latest evidence.

Education

Wickramasinghe studied at Royal College, Colombo, the University of Ceylon where he graduated in 1960 with a BSc First Class Honours degree in mathematics, and at Trinity College, Cambridge and Jesus College, Cambridge where he obtained his PhD and ScD degrees. He was previously Fellow of Jesus College, Cambridge (1963-1973); Professor and Head of the Department of Applied Mathematics and Astronomy at University College Cardiff (1973-1988); Professor in the School of Mathematics, University of Wales College of Cardiff (1988-1998); and Professor and Director of the Cardiff Centre for Astrobiology (1999-2011), now a private company and charity.

Scientific career

In 1960 he commenced work in Cambridge on his PhD degree under the supervision of the late Sir Fred Hoyle, and published his first scientific paper "On Graphite Particles as Interstellar Grains” in Monthly Notices of the Royal Astronomical Society in 1962. He was awarded a PhD degree in Mathematics in 1963 and was elected a Fellow of Jesus College Cambridge in the same year. In the following year he was appointed a Staff Member of the Institute of Astronomy, Cambridge. Here he continued to work on the nature of interstellar dust, publishing many papers in this field that led to a shift of emphasis in astronomy from inorganic dust models to organic grains.

My most significant astronomical contribution was to develop the theory of organic grains in comets and in the interstellar medium. This was done during the 1970s and 1980s, and it is now accepted by everyone almost without remembering its origins! I feel I also played a part in the birth of the science of astrobiology.

He published the first definitive book on Interstellar Grains in 1967. He has made many contributions to this field, publishing over 350 papers in peer-reviewed journals, over 75 in Nature (journal). In 1974 he first proposed the hypothesis that some dust in interstellar space was largely organic (contain carbon), which Wickramasinghe later proved to be correct. Hoyle and Wickramasinghe further contended that extraterrestrial life forms continue to enter the Earth's atmosphere, and may be responsible for epidemic outbreaks, new diseases, and the genetic novelty necessary for macroevolution. In a virtual presentation on April 7, 2009, physicist Stephen Hawking endorsed the hypothesis. Chandra Wickramasinghe had the longest running collaboration with Fred Hoyle and is responsible for forging a link between biology and astronomy in the late 1970s. Their publications on books and papers arguing for panspermia and a cosmic hypothesis of life are nevertheless controversial.

Wickramasinghe was appointed a consultant and advisor to the President of Sri Lanka in 1982-84, and played a key role in founding the Institute of Fundamental Studies in Sri Lanka.

Detection of living cells in the stratosphere

An image of a clump of microorganisms from 41 km fluorescing on application of a carbocyanine dye (indicating viability) is shown in the left panel, and scanning electron microscope image of a similar clump is shown on the right panel.

On the 20 January 2001 the Indian Space Research Organisation conducted a balloon flight from Hyderabad, India to collect stratospheric dust from a height of 41 km with a view to testing for the presence of living cells. The collaborators on this project included a team of UK scientists led by Wickramasinghe. In a paper presented at a SPIE conference in San Diego in 2002 the detection of evidence for viable microorganisms from 41 km was presented. However, the experiment did not present evidence as to whether the findings are incoming microbes from space rather than microbes carried up to 41 km from the surface of the Earth.

In 2005 the ISRO group carried out a second stratospheric sampling experiment from 41 km altitude and reported the isolation of three new species of bacteria including one that they named Janibacter hoylei sp.nov. in honour of Fred Hoyle. However, these facts do not prove that bacteria on Earth originated in the cosmic environment.

Samplings of the stratosphere have also been carried out by Yang et al. (2005, 2009). During the experiment strains of highly radiation-resistant Deinococcus bacterium were detected at heights up to 35 km. Nevertheless these authors have abstained from linking these discoveries to panspermia.

Extraterrestrial microbes

On May 24, 2003 The Lancet published a letter from Wickramasinghe, jointly signed by Milton Wainwright and Jayant Narlikar, in which they hypothesized that the virus that causes Severe Acute Respiratory Syndrome (SARS) could be extraterrestrial in origin and not originated from chickens. The Lancet subsequently published three responses to this letter, showing that the hypothesis was not evidence-based, and casting doubts on the quality of the experiments referenced by Wickramasinghe in his letter.

Wickramasinghe was also involved in coordinating analyses of the Red rain in Kerala in collaborations with Godfrey Louis.

Participation in the creation-evolution debate

Wickramasinghe and his mentor Fred Hoyle have also used their data to argue in favor of cosmic ancestry, and against evolution.

Once again the Universe gives the appearance of being biologically constructed, and on this occasion on a truly vast scale. Once again those who consider such thoughts to be too outlandish to be taken seriously will continue to do so. While we ourselves shall continue to take the view that those who believe they can match the complexities of the Universe by simple experiments in their laboratories will continue to be disappointed.

Wickramasinghe attempts to present scientific evidence to support the notion of cosmic ancestry and "the possibility of high intelligence in the Universe and of many increasing levels of intelligence converging toward a God as an ideal limit."

During the 1981 scientific creationist trial in Arkansas, Wickramasinghe was the only scientist testifying for the defense of creationism and against evolution. In addition, he wrote that the Archaeopteryx fossil finding is a forgery, a charge that the expert scientific community considers an "absurd" and "ignorant" statement.
