Prof. Chandra Wickramasinghe - the man who asserted: "Life did not start here on earth but in space," has retired

By Walter Jayawardhana

Chandra Wickramasinghe the scientist has been always a poet at heart. As a young boy growing up in his native Sri Lanka he looked up at the twinkling canopy of the tropical night sky and wrote : Prof. Chandra Wickramasinghe : "the idea of life being a cosmic phenomenon is fully in tune with Buddhist as well as Vedic philosophy."Prof. Chandra Wickramasinghe : "the idea of life being a cosmic phenomenon is fully in tune with Buddhist as well as Vedic philosophy."

Amongst the myriad stars
I stand alone
and wonder how much life
and love there was tonight

He wrote it at the age of 15.

From his childhood he has mysteriously felt connected with the universe. Being a Buddhist the idea of life having a cosmic connection was in tune with his philosophy.

Some years ago he told me, "the idea of life being a cosmic phenomenon is fully in tune with Buddhist as well as Vedic philosophy. Ancient Buddhist texts described inhabited circling distant suns, collections of suns to form greater world systems , collections of world systems and so on. I have surely been inspired by these philosophies throughout my scientific studies."

A graduate of the University of Ceylon. He later joined the Cambridge University on a Commonwealth scholarship and did his PhD under the late Sir Fred Hoyle, one of the best astronomers of the 20th century. He was later awarded the university’s highest doctorate for science, the prestigious Scd. He was decorated by the President of Sri Lanka with the title "Vidya Jothi". He came to Cardiff University in Wales in 1973 and organized a new department of astronomy that became one of the top astronomy centers in Europe.

After thirty 33 years of work as the professor of astronomy and mathematics, Chandra Wickramasinghe is the world’s leading exponent of the theory known as panspermia- the science that teaches earth and other planets in the universe may have been seeded for life by microorganisms carrying comets.

Before Chandra Wickremesinghe scientists thought that huge obscuring clouds in deep space like the horse head nebula were made up of ice particles. But his untiring research showed the particles were mainly made of carbon- a form of a substance that was connected with life- a freeze dried dormant bacteria.

Wickramasinghe calls them our genetic ancestors. When he first came out with this theory, extremely harsh criticism was leveled against him. Some even called the theory pseudo- science. Chandra Wickramasinghe thinks if there was no Sir Fred Hoyle, one of the greatest astronomers of the last century, stood by him his theory would have certainly been put out of existence. He and the late Fred Hoyle were later awarded the Dag Hammarskjöld Gold medal for Science.

Chandra Wickramasinghe has made his theory of panspermia the mainstream in the new science of astrobiology - a link between astronomy and biology.

To celebrate his new theories, the Cardiff university was holding a scientific seminar to discuss the new view of the world of science that boldly said that life did not start in a primordial soup spontaneously here on earth as believed earlier but it started 4000 million years ago on comets and traveled through space to earth and countless other planets. With the participation of nearly 40 scientists from all over the world the seminar was held from September 5 entitled, Unraveling of Our Cosmic Ancestry.

Though retiring as the Professor at the age of 67 he will continue to serve as the director of Cardiff Center for astrobiology.

The following is an email interview I did from California with him in Cardiff on the eve of his retirement:

Question: You are retiring as a Professor at the University of Cardiff this September. What was the most significant contribution you could make to the progress of science during the time you served as the professor of applied mathematics and astronomy since you came to this university in 1973?

Answer: I played a key role in establishing a connection between astronomy and biology. My work in the 1980's showed for the first time that cosmic dust had properties that resembled the properties of living material and their degradation products.

Question: When you were at Cambridge, before coming here, your Pioneering research was on interstellar dust. What is the significance of those theories on interstellar dust?

Answer: My PhD thesis and the dissertation on which I was awarded a Fellowship at Jesus College was entitled: "On graphite particles as interstellar grains" I think I was largely responsible for astronomers moving away from the old idea that cosmic dust consisted of ice particles that were formed in space to the idea that they condensed in much denser regions in the environs of stars. I also transformed showed that interstellar dust played a key role in controlling astrophysical processes.

Question: Once when you were in California, you told me that
you and some Indian team of scientists using balloons had collected from the tropopause , or the upper atmosphere microorganisms that had come from outer space and your estimate was that one third of a tonne of cometary microorganisms enter the earth's atmosphere every year. What are these micro organisms ?

Answer: I think that life arrived at the Earth 3800 million years ago with the impacts of comets. If comets brought the first life to Earth the process of comets introducing primitive life must continue even to the present day. The Indian balloon experiment gave us the first direct indication that this may be happening. The particles collected in the stratosphere included clumps of bacteria, which we know are viable (living), but so far we have not been able to culture most of them.

Question: At that time you said the scientists are going to do detailed analysis of these microorganisms and look in to their DNA. Have you looked into the DNA now? Are they different from the microorganism you find on earth? Can you compare them?

Answer: A few types of bacteria that were grown from the air samples by Milton Wainwright in Sheffield were found to be similar to known terrestrial counterparts, so contamination from the Earth is always an issue. The clumps of bacteria that we could not culture or sequence DNA we think must have come from space.

Question: If they came from outer space from where did they Actually come and how? How did they survive in the deadly outer space with all those killer rays?

Answer: They came from comets. When the comets formed at the time of the birth of the solar system they would have included a very small component of viable bacteria from the cloud from which our planetary system condensed.

These bacteria then grow exponentially in numbers in the liquid interior regions of comets. When comets come into the inner regions of the solar system their surfaces are peeled away, and the bacteria particles escape into the cometary tails.

Whenever the Earth crosses trails of cometary debris, biological particles would enter the Earth's atmosphere. Not all the biological particles survive entry of course, but a fraction must do. I don't think survival in the so-called harsh conditions of space is an issue any more. Bacteria are found to be exceedingly space-hardy.

Question: Recently, the Kerala scientist Dr. Godfrey Louis and his research assistant Santhosh Kumar said samples of red rain that fell across the state of Kerala in India have been found to contain microscopic red cells of unknown origin . What's the relevance of this claim to your theory of panspermia? Could you also tell something about their latest conclusions?Dr. Godfrey Louis said samples of red rain that fell across the state of Kerala in India have been found to contain microscopic red cells of unknown origin . Dr. Godfrey Louis said samples of red rain that fell across the state of Kerala in India have been found to contain microscopic red cells of unknown origin .

Answer: If these red cells came from a comet, then it would surely be conclusive proof of cometary panspermia. The evidence to me suggests that a small injection of red rain cells from comets took place in July 2001, and this was somehow amplified in the clouds of our atmosphere. This is the only way I can understand the intermittent showers over several weeks, and the localization around Kerala. Incidentally this phenomenon was repeated in this present year July 2006, showing a 5-year cycle of incident particles.

Question: We heard that samples of this red rain was also sent io Cardiff for testing. What did you find? Could these also be aliens showering on earth after traveling on a comet?

Answer: I think more work needs to be done, but this could well be the smoking gun for panspermia.

Question: It was claimed in news reports that these microorganisms lacked DNA. Then how did it replicate?

Answer: We also have had difficulty extracting DNA from these exceedingly tough red-rain cells. There are however some staining tests that show positive for DNA, but this could be ambiguous. Again, we need to extract and amplify DNA, which we have not yet done.

Question: It was also claimed in news reports that the strange Cells would reproduce in 600 degrees Fahrenheit while the known maximum limit of heat in water for any life to survive is only 250 degrees of Fahrenheit. Are they bacteria adapted to the harsh conditions of space? Is this going to be the first concrete evidence for your panspermia theory?

Answer: These are Godfrey's claims. I think these claims have to be tested independently and if they are verified, they surely would be a confirmation of an alien bug.

Question: What did you find out from NASA's star dust program? Were you able to test some samples from that program?

Answer: I have not had access to these samples. But the collection procedure would not have recovered microbes in tact. The organic residues found in the aerogel can be interpreted as destruction products of bacteria.

Question: If you think the intelligent man ultimately evolved out of these unearthly microorganisms from outer space couldn't those same spores of life contributed to intelligent life elsewhere in the universe?

Answer: Yes, I would agree. The universe must be teeming with life, and with intelligence as well.

Question: So, if we are to meet a visitor from space one day, who has mastered time traveling do you think that visitor would look very much different from man?

Answer: He she or it would share much of our genetic heritage. Our genes, and the genes for all life were derived from a much bigger cosmic system. So a similarity of life forms across the universe is inevitable.

Question: Do you think based on the studies of DNA from outer space that the visitor from outer space would be a compassionate one or a one who would be planning to devour us for protein.

Answer: I think if a visitor from space had developed the technologies to travel to us, that visitor must come from a "culture" where survival over millennia and coexistence had evolved as prime values. Otherwise they would have blown themselves out in a matter of tens of thousands of years, as our civilization may well be heading to do.

Question: Would it be a carbon based life or a silicone based life?

Answer: The only life we know of is Carbon based, so I would like to stick to that as the only life form to discuss.

Question: A US suspense and mystery writer has written a novel depicting a space visitor entering our bodies and destroying us. How could such barbaric practice be possible among an advanced civilization who could conquer space and time?

Answer: I think that is beyond belief!

Question: Do you think there are any chances of contacting an intelligent civilization in the near future?

Answer: I would give it 3 decades, no more before contact is made.

Question: What benefits such a contact could bring to this world?

Answer: I hope that it would lead to a world view in which tribal and International conflicts cease to exist.

Question: What are the chances that our civilization could come to an end before all that by a nuclear war or the collision of earth with an asteroid or a comet?

Answer: Yes, comet and asteroid impacts may present a very long-term threat to our civilization, possibly over a timescale of a few thousand years. But on a much shorter timescale nuclear wars could pose the most serious threat. The rate at which we are amassing lethal weapons is certainly very disturbing.
