How Comets carry seeds of life across space

Earlier posts in this blog have postulated that life does not exist just on earth but is rather widespread across the universe albeit in planets too far from each other to make contact, it further postulated that life spreads across space through comets as bacteria and viruses, the only form of life that may survive as frozen life in the long journey from one planet to another and that comets may be formed as fragments of life bearing planets.
Once such bacteria arrive on a planet that has sunlight, temperatures in the appropriate range and gravity enough to hold an atmosphere etc. for life to exist, then life begins to unfold slowly on the planet over billions of years. True such planets would be rare but seeing that the universe is a virtual infinity of stars they are likely to be many. The earlier articles were written more than eight years ago and can be found as early posts in this blog. Just check out the archives in the left sidebar. Since then new discoveries have substantiate…

How The Ice Age gave birth to Human Civilization

Everyone knows of annual variations that take place as the Earth orbits around the Sun. However there are other much longer duration variations that also take place. As the Earth spins around its axis and orbits around the Sun, several other periodic variations occur. Milankovitch, a Russian Scientist, studied some of these changes in Earth's movements and described what are known as Milkanovitch Cycles. Such changes in movement and orientation alter the amount and location of solar radiation reaching the Earth and are a cause of various ice ages and variations within the ice ages that the planet has witnessed in the past. There are other factors that also contribute to the occurrence of such major climatic changes.
There have been at least five ice ages in the past and presently we live in a relatively warm portion of an ice age that is currently on. That is why the polar ice sheets still exist. Some say that this will end after 50,000 years while a recent research study says i…

New Evidence form Rosetta Mission Supports Pansemeria Hypothesis

How life came to Earth
Some of the earliest posts of this blog dating back to 2006 suggested that seeds of life were brought to earth by comets. The theory can be reached quickly by clicking archive links in the side bar. The theory named Pansmeria, an adaptation and detailing of the Panspermia hypothesis, then went on to develop a model of how life emerged on Earth and how it may emerge similarly on other habitable planets of the universe where temperature is in the range to permit presence of liquid water, sunshine conducive for photosynthesis and gravity sufficient for holding an atmosphere. Some of the precise details of the theory may need slight revision but this blogger stands by the overall picture as originally presented. Every new evidence that has emerged from science since has supported it.
Now new evidence from the Rosetta mission support the founding principle of the hypothesis of eight years ago, that comets can bring life to Earth. See this report from CNN,

New Studies push back dates of ancient human civilization

With new archeological finds the dates of ancient human civilization are being pushed back,
“Asia's largest and oldest metropolis with gateways, built-up areas, street system and wells was built at the site of Haryana's two villages, including one on the Ghaggar river, according to a new Archaeological Survey of India (ASI) report. The report, based on C 14 radio-dating, has said the mounds at Bhirrana village, on the banks of Ghaggar River, in Fatehabad district date back to 7570-6200 BC.”
The 356-page research on Rakhigarhi has been authored by former ASI's archaeology director Dr Amarendra Nath, the holistic study on Bhirrana has been compiled by ASI's former joint director general K N Dikshit and addtional diector general B R Mani.

However, as speculated in some earlier posts yet more ancient remains may now be submerged in coastal regions of Southern India and these sites may be a result of a return to the northern plains with a language similar to archaic Tami…

On the Tamil origin of Ancient human civilisations

Thinking and motivations, both good and destructive, in society develops over centuries from its experiences. Since these experiences are different in different parts of the world, it is not surprising that some of this thinking is different. Usually in fictional imagination when visits by aliens from other worlds are visualized, many in western societies imagine them as attacking humans. This has surprised people from India, why would they attack? It is so much easier, nice and advantageous to love instead and if there are aliens intelligent enough to learn travel through space surely they are not as stupid as to pounce on humans jumping around and shouting hoola hoola hoo! They would rather sit in a nice bar or tea house and discuss how humans reproduce and make love and how they could do some joint projects to benefit all. This was the philosophy of ancient humans too that gave birth to human civilization in Southern India and later Indus-Saraswati valley, Sumeria etc. The dark for…

Comets are not Vagabonds

Those who believe in a supreme Universal Intelligence believe that nothing major happens in the universe unless the Universe wills it. While scientists recognize the supreme organization in planets, stars and galaxies, some regard comets as wayward objects. However, there are others who see this as a necessity of the overall design. An earlier post (see here) in this blog described how comets may be regarded as the spaceships of God. Their icy interiors can bring genes of life stored in bacteria, the only form of life that survives hibernation over millions of years, acting as the seeds of life on new planets, where they awaken with the scent of moisture and a conducive climate. The genes of all life forms including humans are carried in bacterial genes. There is much more of that in earlier posts of this blog. Presently the earth is witnessing the spectacular comet Lovejoy in its vicinity.

Without comets, perhaps there would have been no life on earth. It is also true that some comet…
