HAVE you ever found yourself in a high place -- say 2000 ft or more above sea level -- at night with a clear, cloudless sky with no city lights around to obscure the view?  And have you surveyed the night skies under such conditions?  If so, have you wondered -- and wondered?  What’s that all about -- that tapestry of twinkle?  What’s out there-- are there folks - beings - creatures out there?  Are they like us?   Or are they totally different looking from us?  Can they think?  Talk?  Read and Write?  Vote?  Are there planets like ours with trees, animals, insects, spiders, flowers?  Are there waterfalls, mountains,  rain, snow and sandstorms?  Do they have poetry, music, gourmet meals?  Just what do they eat???

 

Imagination and curiosity are partly a factor of intelligence -- but more so they are a factor of developed attitude.  Some people are notoriously incurious.  Confronted with such a spectacle, they would mentally process something like: Very pretty, but idle speculation will not provide me with knowledge or facts which are unavailable.  “Honey-- where’s the TV guide and what’s for dinner?  Please hand me a beer.

 

The innate curious amongst us on the other hand, would process differently. The would ask themselves all the above questions, and wonder about what it meant.  If there were other sentient (thinking) creatures out there, how did they get there?  For that matter, how did we get there?  Is our development related to that of alien life on other worlds?  Where and how did it all start?  Why?  And where will it go from here? What’s the purpose of all this, anyway?

 

Being one of the innate curious type, I will dwell into some of these speculations in the next little while, armed with some scientific fact, some history, some speculation, and little likelihood of answering any of the questions.  Open your minds fully to the  possibilities and join me in this mental and philosophical journey.  People have done it since the beginning of mankind -- OOPS --  peoplekind.  Back after the station break.

STARGAZING IN HISTORY

 

On Feb 15, 1564 one of the innately curious of our past was born as Galilei Galileo in the country of Italy.  Born in an environment of rigid Roman Catholic Christianity, Galileo nonetheless, was curious and was led by his curiosity to study the science of the day  and to wonder. Galileo, born to an inventive  musician father, was drawn to study mathematics, and eventually became a professor of mathematics.  He experimented with the physics of the day and contributed to a new understanding of the principles of gravity.  As a struggling professor at the University of Padua, he took on other teaching responsibilities, one of which was the study of military architecture and fortification, and from these endeavors sprung the first of his commercial inventions, a geometric compass  - like you used to use in geometry class. His intellectual queries led to his papers on the theory of free fall and the laws of the lever.

 

 In the summer of 1609, he was distracted from his studies of physics by news of a Dutch development, the spyglass. Galileo acquired one at his first opportunity, and seeing the advantages of this device for military uses, he set out to study and improve it. He redesigned it making the image magnification much more powerful, grinding and polishing his own lenses,  and Voila -- he had invented the telescope.  His first telescope had a magnifying power of 20.

 

For a time, he studied the face of the moon, and inspired by the details available, he set out to further improve the design of the telescope, making it still more powerful ( now improved to 30X power). He trained his new invention on the stars, and quickly distinguished between the two types of stars, those fixed in position (stars) and those that wandered through the skies (planets). He stated “ Planets show their globes perfectly round and spherical and are flooded all over with light.  The fixed stars never appear circular, and their light has the aspect of  blazes which scintillate a great deal”  Thus, tool-aided astronomy had its birth. In separating the stars from the planets, and finding other planets in space, Galileo had confirmed that there are “other worlds”.

 

Of course,  this interest in the heavens was not new.  Even primitive  people had observed the skies in awe and wonder. But unarmed with basic science or tools of magnification, they had left their studies to the future and used their knowledge principally for celestial navigation, and for religious or mystical conjecture and poetry.

 

It is even more interesting that ancient cultures believed openly in alien life in space and it was not until the rigid Christianity in the centuries around Galileo that this suggested conflicts with religion.  Below are excerpts from a philosophical poem written by Lucretius, a Roman poet and philosopher  98-55BC


THERE ARE MANY WORLDS

Now here is something we must not think probable,

Since space is infinite on every side,

Since atoms numberless throughout the mighty universe

Fly here and there, by motion everlasting, e’er implied,

That this one world of ours, this earth and sky

Alone were brought to birth.

 

Beyond the confines of this earth we know,

Nature does nothing.

Particularly as the world we know

Was made by Nature thus:

The atoms of their own accord

Jostled from time to time by chance,

In random fashion, clashed, and blindly, heedlessly

And oft in vain,

Until at last were unions suddenly achieved

To be the starting points of mighty things,

Of earth and sea and sky, of every living thing.

 

And so I say again, again you must confess

That somewhere in the universe

Are other meetings of the atom stuff resembling this of ours;

And these the aether holds in greedy grip.

For when the atom stuff is there,

And space in which the atom stuff may move,

And neither thing nor cause to bring delay,

The process of creation must go on;  things must be made.

 

Now as it is,

If atom stocks are inexhaustible,

Greater than power of living things to count,

If Nature’s same creative power were present too

To throw the atoms into unions -- exactly as united now,

Why then confess you must

That other worlds exist in other regions of the sky,

And different tribes of men, kinds of wild beasts.

 

This further argument occurs:

Nothing in nature is produced alone;

Nothing is born unique, or grows unique alone.


ASTRONOMY AND RELIGION

`

By the time of Galileo’ telescope,  the current scientific community and the Christian church had accepted the Aristotelian cosmos theory; i.e. The earth was the center of the universe, and the sun and other bodies all circled the earth.  Lacking tools of  closer examination, scientists accepted Aristotelian theory as fact;  furthermore, it was not really in conflict with Christian theology of the time- or at least was easy to accommodate as it certified the uniqueness and importance of earth and its inhabitants.  With the issue of Galileo’s first two books, the challenge to Aristotle’s theory was in place. Other astronomers and the church reacted vigorously.  Galileo had refuted the theories of Aristotle and replaced them with then newer teachings of Copernicus.

 

Copernicus, a Prussian born in 1507  had studied the Ptolmeic and Pythagorean systems from his youth, and was entranced by astronomy.  After thirty six years of hesitation, he published his book in 1543 establishing the theory of a heliocentric system, with earth and the other planets circling the sun. His hesitation was in fear of outraging the church with views contrary to “revealed truth” and would surely bring him punishment.  As expected, the inquisition labeled his work “that false Pythagorean doctrine utterly contrary to the Holy scriptures”.  In denouncing the Copernicus system as being in contradiction to revelation, the ecclesiastical authorities  stated “that such theories dethrone the earth from her central dominating position, to give her many equals and not a few superiors, and deemed to diminish her claims upon divine regard.” A copy of his publication was brought to him on his death bed.

 

Galileo, in supporting the theories of Copernicus was promptly summoned to the court of the Holy inquisitioners on the charge that he was teaching a doctrine utterly contrary to the Scriptures, and was given the opportunity to renounce this heresy and abstain from all future writing or teaching of such views.  He complied for 16 years, then compelled by new  intellectual enthusiasm, he published the work, “The System of the World” revisiting and again promoting the Copernican theory.  He was arrested, forced to kneel with a hand on the Bible and abjure and curse the works he had published; then he was subjected to house imprisonment for the last 10 years of his life.  His is only one drama of early scientists suffering imprisonment or even burning at the stake for views of astronomy deemed heretical to the scriptures.

 

The views of origin of life as a miracle persist even in an age when space travel is now common and space viewing with grossly improved technology is firmly in place.  And the conflict between Christian theology and science are more hotly debated.  When an early astronaut first orbited the earth for some time, and was welcomed back to earth with much fanfare, it is reported that one reporter for a Christian magazine asked the astronaut somewhat dubiously, “Did you see God when you were up there? What does he look like?”.  The  incredulous astronaut reportedly replied:  “Yes I did. She was black.”  There is apparently no room for accommodation in strict Christian theology for space travel -- and much less possibility for alien life.

The English philosopher, Richard Bentley confronts this narrow view of the origin of life with the thought:   If one chooses to believe that God created this earth for the primacy and use of mankind,  why would God not have also staffed the planets of other suns with intelligent life. Why must Earth be thought to have exclusive rights to the whole universe?

 

ALIEN LIFE

 

So just what do scientists really know and think about alien life on other planets?  Since Galileo’s telescope arrived, many other scientific advances have been made for examining space and recording results. Galaxies have been photographed in vivid glorious color and put on Internet for anyone’s casual observation. (See NASA.org). The Hubble telescope has been used successfully for many years now to photograph  the cosmos at great magnification, from orbit, free from the obscuration of earth’s wet and dusty atmosphere. Jovian moons have been photographed. Nebulae and pulsars and black holes and supernovae and other new viewings have increased our knowledge and our vocabulary , as new terms had to be coined for new celestial features.

 

In October, 1992  NASA launched a serious new  effort to search for alien life in the universe.  Know as SETI -- Search for Extraterrestrial Intelligence -- it consists of  groups of radio telescopes located around the world to continuously monitor radio frequencies at varied frequencies bands, targeting star-systems in hopes of hearing intelligent radio signals from outer space.   In the fourth century BC, the Greek philosopher Epicuras wrote a letter to Herodotus: 

            [There are infinite worlds both like and unlike this world of ours. For the atoms being  infinite in number....are borne on far out into space.  For those atoms which are of such nature that a world could be created by them or made by them have not been used up on either one world or a limited number of  worlds.

            So that there nowhere exists an obstacle to the infinite number of worlds....]

 

Thus the belief in life in outer space has philosophically been part of our existence since the fourth century BC and possibly much earlier. The teachings of Epicurus (atomism) were a primary influence on Lucretius and much of his poetry and literature.

 

The SETI  search for signals not of natural origin  (matter radiates signals too) has not yielded any results, but scientists are now beginning to understand why the possibility for signals from space is unlikely --or at least improbable.  It does not suggest that the probability of life in outer space is impossible;  rather it takes in account the problems created by the time and duration of life on a planet.

 

Many cosmologists now believe that the universe came into being 15 to 20 billion years ago with the big bang. (They don’t know why!). [There is a second conflicting school of thought that the universe is a steady-state thing. That is there was no real beginning and there will be no end -- it is eternal, but with constantly dying and newborn heavenly bodies. ]  Over the billions of (earth) years after the alleged big bang, the galaxies and the solar systems gradually took form under the influence of gravity.  Our  solar system may have formed some 4 billion years ago and commenced cooling over the ensuing millions of years.  Earth, when formed, was believed to be very hot and mostly ocean.  The only land was volcanic peaks which belched out streams of hot molten lava.  The atmosphere was dense and unbreathable, devoid of free oxygen.  As the earth cooled over millions of years, the atoms reformed under intense gravity into heavier elements.  Earth, and other planets also endured constant bombardment from meteorites, asteroid, and other forms of “star-dust” containing all the heavier elements necessary for the creation  of life forms. When this was far enough along so that carbon, nitrogen , oxygen, hydrogen and phosphorus and iron were present we had set the stage for biogenesis --- the beginning of life on earth.

 

But archeological fossils only trace simple single cell life forms back as far as 1 billion years, (these were similar to amoebae or protozoa).  The oldest  complex” life form known as Ediocara dates back to about 560 million years and was found in Australia near Adelaide.  These fossils were still simple, resembling a present day jellyfish.  Then, about 545 million years ago,  life started branching out at a great rate. Plants and animal fossils from this era are much more prolific.  But  earliest primate fossils date back only about 35 million years;  hominids date back only about 9 million years.  Early technical man was in 1400’s AD (The Renaissance &Leonardo De Vinci is born),  and as already shown, Galileo dates back to 1600 AD or so.  Earth folk started exploring space in the 1960’s and much of modern cosmology is only 25-50 years old and still developing.

 

Rounding off numbers cavalierly,  we see that technological man has only occupied earth for the last 600 years or so out of an earth life span of perhaps 10 billion years. This figures out to 6  x   % , or 0.00006 % of earth’s apparent history. Any form of early man would exist on earth only 9 million out of earth’s 10 billion year history or about 0.0001% of earth’s history. So what’s the point??

 

Just this.  Although cosmologists believe that all matter was unloosed by the big bang, the solidification and formation of the universe would have stretched over many billions of years. So other civilizations (if they exist) could be a billion years apart from us either before or behind.  The time span is so huge, and the time targets so tiny that the probability of coexisting with other intelligent mortals on other planets at the same time is indeed very remote. On the other hand they may have already existed, or may sometime in the future exist. So establishing contact will be problematical at the least.

 

BIOGENESIS - THE TRICKY PART

The theories that go into biogenesis are highly speculative and based on the basic sciences of archeology, biology, chemistry, physics, and astronomy. Imagination and reason are used to patch in the important parts missing from our current scientific knowledge. Biogenesis is basically the art of autonomously developing from inert chemical molecules into a living thing.  Living things differ from non living things in the following ways:

Ÿ         Autonomy:  Living things do things their way, i.e. move, eat, reproduce. They are not immobile like a rock.

Ÿ         Reproduction:  Living things can reproduce their own species (except mules) according to        a complex genetic code. All living things have DNA. Exception: crystals can also reproduce.

Ÿ         Metabolism: Living things have metabolism which means they require food, drink, air or whatever chemicals they require to metabolize. It also means they are not immortal, but live a fixed life span, based on when they wear out chemically or nutritionally..

Ÿ         Nutrition:  In order to metabolize, they must feed. Nutrients are peculiar to the life form.

Ÿ         Complexity:  Life forms of all types are exceedingly complex. Their activity is unpredictable. The parts of the life-form must interact in a complex manner to support life. Consider the human nervous system, lungs, heart, blood, brain, etc....

Ÿ         Growth:  Living things grow and develop from an early stage to their late stages prior to expiring. Thus they change form during their life.

Ÿ         Information content:  The information for reproducing is passed on from the parent in the form of genes.  The source of the information in the genetic code remains mystery to the scientist. Where does it develop and from what information source?

Ÿ         Permanence and change:  Reproductions follow the genetic code to build an identical form. But outside influences count too. Environment causes life forms to adapt and mutate, thus gradually becoming different from their ancestral forms.

 

The first great debate was whether the elements necessary for life (carbon, nitrogen, basic protein ingredients) could “autonomously” form on earth due to evolving conditions and constant bombardment of cosmic energy or whether the necessary ingredients were brought to earth by cosmic bombardment of meteors and comets. Either way, the elements were formed, and make up part of the list of chemical elements known today as our periodic table, all the chemical elements found on earth today, which includes all the chemicals necessary for the development of life forms.

 

Newer instruments for observation of the heavens such as X-ray, infrared, and other wavelength specific telescopes, coupled with mass spectrographs  absolutely confirm the existence in outer space, in other star groups, asteroid belts , meteors, and comets and in dust clouds in space of these life-forming essential elements. It is believed that they were created in the process of solidifying other stars, many of which exploded and projected these elements into outer space as meteorites or asteroids.  It is now a firm belief that we living organisms on earth are literally made of star dust.

 

The next great(er) debate is,  given the eventual presence of the necessary elements to make living organisms, how did they get “arranged” into the architecture necessary for life. Where and under what influence did the architecture (genetic codes) develop. What breathed life into one set of complex chemical molecules, but not into simpler molecules (rocks and minerals in general). As yet, we have no definitive answers.

 

The puzzle gets even murkier, when one distinguishes between “life” and “sentient” or conscious life.  While many wild or domestic creatures obviously have “intelligence”, the intelligence does not extend to the capability of  creativity or invention.  A porpoise has the intelligence, they say of a 9 yr. old human;  but to our knowledge, no porpoise has been able to create or play a symphony or paint art.  Porpoises , apes , dogs, and chimpanzees (not cats) have been taught to communicate with humans and to register understanding of human speech. But no creatures other than man has demonstrated the capacity for creating complex  innovations -- for building complex structures or mechanisms for some obscure use fashioned in his imagination;  i.e.  a typewriter, a kitchen appliance, an automobile, an atom bomb.  Most intelligence demonstrated by the chimpanzees, porpoises, and other bright animals seems to stem from reacting to outside influence -- or learning by rote to perform tricks for reward.  Many animals (beavers) build their dwelling or operate with simple tools to aid in feeding or housing themselves.  There is a big gap indeed in that and developing a system capable of sending wireless communication or of carrying a man to the moon.

 

The mystery deepens;  what is the source chemically or environmentally of this deeper insight, imagination,  and mental sophistication that man seems to have and other earth species do not.  Are there species in outer space that share this sophistication?  Have they developed a technology similar or superior to ours?

 

AND FINALLY

Scientists and engineers do not know the answers to these cosmic mysteries.  But they are questioning them.  They are curious and  actively pursuing the science for answers.  They are part of the innately curious of our species.  They have cloned creatures in the laboratory using DNA to see if it could be done.  They have successfully engineered purposeful genetic mutations on plant life, and on animals to endow the mutated offspring with an improved quality of some desired type.  All of which  has been accompanied with some outcries of controversy and alarm. (Playing GOD).

 

The creative powers of man are not without dangers.  As we develop our technological skills much faster than our social or ethical values, we are in danger of destroying ourselves with our new knowledge.  We have stood on the brink already of global nuclear disaster as we endured years of stalemated cold wars. We  have harnessed enough destructive power to destroy mankind several times over.  But we have not developed socially nor ethically yet to understand how to feed and clothe  and house the hungry and destitute of our own kind.  We have not learned yet to use our  sophisticated creative powers to the betterment of all life in the universe.

Maybe we will...... Maybe we will......

 

Maybe aliens will come and show us. Or maybe they have already developed their technology so far beyond their social and ethical values, they have destroyed themselves!!    Still, my greatest goal in my life is to see/meet an outer space alien.

Such is the fate of the innately curious.
