DIRECTED PANSPERMIA PDF

A co-discoverer of the double helical structure of the DNA molecule, Crick found it impossible that the complexity of DNA could have evolved naturally. Crick posed that small grains containing DNA, or the building blocks of life, could be loaded on a brace of rockets and fired randomly in all directions. Crick and Orgel estimated that a payload of one metric ton could contain micro-organisms organized in ten or a hundred separate samples. This would be the best, most cost effective strategy for seeding life on a compatible planet at some time in the future. The strategy of directed panspermia may have already been pursued by an advanced civilization facing catastrophic annihilation, or hoping to terraform planets for later colonization. Support for Directed Panspermia Directed panspermia from Earth to new solar systems has been proposed to expand life in the Universe.

What is the theory of directed panspermia? Question: "What is the theory of directed panspermia? This hypothesis is a very specific sub-division of a broad group of related ideas. A committed atheist, Crick once resigned from a collegiate position because the college elected to build a chapel. Crick found his belief in an undesigned, naturally-controlled universe challenged by his discoveries. In particular, Crick found it impossible to believe that DNA could have evolved, based on his knowledge of its structure and the principles of naturalistic evolution.

Rather than consider the possibility of DNA being the deliberate construction of an intelligent Creator, Crick mused about ideas like exogenesis, panspermia, and directed panspermia.

Crick has since re-affirmed his commitment to the evolution of life on earth from purely natural mechanisms, though with significant questions left unanswered. Directed panspermia—as well as the more general ideas of panspermia and exogenesis—are not well accepted in the scientific community.

Some see these ideas as semi-contradictory to naturalistic evolution. In reality, the question of how life began on earth is different from the question of how that life progressed. The preferred belief about the origin of earth life is that of abiogenesis the supposed development of living organisms from non-living matter, also called spontaneous generation , for several reasons.

The most overt of these is a lack of evidence suggesting that exogenesis of any kind is likely. Second, a pre-commitment to naturalism is threatened by any suggestion that life might have anything other than a natural origin. Questions about life originating elsewhere raise additional questions about designed or created life, which is not a comfortable topic in naturalistic circles. Directed panspermia is one of the many strange hypotheses that have been suggested to explain the origins of life on Earth.

While speculation on the evidence supporting evolution rages on, there is little, if any, accepted support for life beginning naturally in the first place. To have life with no God, naturalism has to answer the riddle of abiogenesis , a concept thoroughly refuted by everything known in biology.

Ideas like exogenesis and panspermia are side effects of an attempt to rationalize belief in a universe devoid of God. In this one sentence is everything needed to satisfy completely the basic principles of natural science, the science of foundational things. Natural science deals with a matrix when referring to the material universe. For the complete matrix, you have to have matter, force, energy, space and time. Those five things are all in Genesis , "In the beginning [time] God [force] created [energy] the heavens [space] and the earth [matter].

The universe is a matrix of space, time, matter, and energy. And all of it has to be existing at the same conflux. It all has to come together or none of it exists. One cannot exist without the other. The entire continuum must have existed simultaneously from the beginning. That is why you find it all in Genesis It all had to be there.

Science says it has to be there and Scripture says it is there. The theories of exogenesis, abiogenesis, and panspermia are simply wrong. Theories and philosophies come and go, but the Word of our God is true, trustworthy, right, and perfect, and it stands forever 1 Peter

Directed panspermia

Search directed panspermia Directed panspermia is the idea that life might have been intentionally spread throughout space and seeded on the surface of other worlds by a guiding intelligence. A detailed version of this hypothesis was put forward in by the molecular biologists Francis Crick codiscoverer of the structure of DNA and Leslie Orgel. The probability of successful seeding would be greatly increased, they pointed out, if the fertilization were carried out deliberately by an existing technological civilization. Their argument depended first upon demonstrating that it was possible for an advanced extraterrestrial civilization to have developed in the Galaxy before life first appeared on Earth. This they were able to do see extraterrestrial civilizations, ancient.

Panspermia

These calculations show that relatively near target stars Alpha PsA, Beta Pictoris can be seeded by milligrams of launched microbes; while seeding the Rho Ophiochus star-forming cloud requires hundreds of kilograms of dispersed capsules. Their methods failed to recognize a well-known functional association in the genetic code; they did not rule out the operation of natural law before rushing to falsely infer design Nothing in the genetic code requires design. The first suggestion came from Chandra Wickramasinghe , who proposed a polymeric composition based on the molecule formaldehyde CH2O. Usually this occurs when a molecule becomes ionized , often as the result of an interaction with cosmic rays.

The Origins of Directed Panspermia

Panspermia and the Origin of Life on Earth Panspermia is a Greek word that translates literally as "seeds everywhere". The panspermia hypothesis states that the "seeds" of life exist all over the Universe and can be propagated through space from one location to another. Some believe that life on Earth may have originated through these "seeds". Mechanisms for panspermia include the deflection of interstellar dust by solar radiation pressure and extremophile microorganisms traveling through space within an asteroid, meteorite or comet.
