Lawrence M. Krauss Shares How Far We Have Come, and How Much Further We Have To Go

 


The Known Unknowns: The Unsolved Mysteries of the Cosmos – Lawrence M. Krauss (2023)

 

            If I could define myself with just one word, it would be “reader.”  Everything in my life either stems from, or draws from, the many books I have read in my 49+ years on this planet Earth.  My biggest heroes, Kurt Vonnegut, Robert Anton Wilson, Richard P. Feynman, etc., came into my life through the written page.  When I began RXTT’s Book Journey almost ten years ago, I dreamed of the possibility that book publishers and authors would appreciate my reviews and want to share their soon-to-be-released work with me.  Dreams do come true.

            The latest advance copy received by the RXTT household is physicist Lawrence M. Krauss’ forthcoming book, The Known Unknowns. (That is the UK title.  The book will be titled The Edge of Knowledge in the USA, probably because Donald Rumsfeld’s use of the phrase “known unknowns” became such a joke in ignorant America.)  After requesting it from Mr. Krauss himself, he contacted his publisher on my behalf and I was sent the book.  MIND BLOWN.

            The reason I read is to enlighten myself, both with new ideas and new information, for I am a curious mind.  Sometimes, the most useful and valuable books are not the ones with the most data, but instead the books with the best questions.  One such book, among many faves, is Richard Feynman’s The Character of Physical Law, a book full of ideas and questions which, it turns out, was also a guiding light for Lawrence M. Krauss.  Feynman’s spirit, willing to share ideas in a thoughtful manner, directly engaged with the toughest questions, and able to explain the most obtuse scientific thought in a manner where a layperson can grasp the fundamentals, is alive and well in Mr. Krauss.  We are all very fortunate.

            Krauss divides this book into five chapters, each one concerning itself with a specific topic where science has shed some light, but where there are still far more questions than answers.  Time, Space, Matter, Life, and Consciousness are the guideposts for Lawrence M. Krauss to not only sum up our current knowledge, but to also point out the vast gaps.  Our collective ignorance is the greatest impetus towards science, scientific discovery, and new knowledge.  The very worst of humanity arises when humans feel absolute certainty, whether political, religious, or social.  Not knowing is the greatest gift to an inquisitive mind.

            My biggest surprise as I devoured this book was its readability.  There are many amazing minds in the world of science, and physics specifically, but very few have the ability to provide us their thoughts and knowledge in such a fun and engrossing manner.  Some books, even great ones, can be a chore to read.  Lawrence M. Krauss has succeeded in creating a book that will enlighten young and old alike, while also opening up their minds to the myriad possibilities yet available for exploration and research.  This may be this book’s most valuable contribution, sparking the mind of some young students out there, and starting their paths toward new discoveries, new fields of research, and, hopefully, new questions.  Questions are truly important.  Anyone claiming to have all the answers is trying to rip you off, and should be treated accordingly.

            Each chapter begins with questions.  For example, the chapter titled Matter starts with these:

What is the World Made of?

How Many Forces are there? 

Is Anything Fundamental?

Is Quantum Mechanics True? 

Will Physics Have an End?

Will Matter End?

Krauss perfectly encapsulates our current state of knowledge in each chapter, sharing it with the reader through the specific details of past scientific achievement.  He then explores how we came to find that knowledge, use it, and seek to understand the underlying principles involved.  One of the best attributes of scientists is their humility in the face of new data.  It allows for self-correction, which is why the scientific method has been such a valuable tool for humanity.  Krauss details the baby steps taken in our human search for knowledge, steps often met with wildly erroneous interpretations, each of them critical points in our collective knowledge.

            Krauss brings his physics knowledge to bear on what is the most complex and mysterious part of our everyday world, the quantum realm.  He guides the reader through the many different steps us humans required to comprehend that the sub-atomic world even existed, and details plainly why it remains such a difficult science to explain.  Everything in our modern world is touched by subatomic processes, from the manufacture of medicine, to the Global Positioning Satellite System, to the various smart phones and gadgets we all take for granted.  None would work without our collective understanding of the processes involved in the quantum realm.  The irony remains that, even as we use quantum science to create new wonders, we still do not fully grasp exactly what processes allow for these modern marvels to function.  We are much like the ancient humans who used fire to bake clay, cook food, warm their home, and provide light, but had no clue as to what caused the fire to exist in the first place.  We now know that free oxygen atoms in our atmosphere combine with the carbon in wood, and that this reaction creates new compounds (Carbon dioxide, water vapor) and energy (light, heat).  It seems common sense to us now, but to a human living 500 years ago this would be utter nonsense.  They “knew” that fire was but one of the four basic constituents of everything that exists, along with Water, Earth, and Air.  For centuries, this basic explanation served its purpose, but it did not actually provide verifiable, repeatable truth.  Only the scientific method does that.

            I hope that this book receives a very wide readership, for it is as equally valuable to a young scientist as it is to a layperson interested in big ideas.  Our world bounces back and forth from close-minded totalitarian fundamentalism to wide-open progressive ideals.  It is very easy for a society to lose ground, to lose hard-earned knowledge and wisdom, because someone, or something, claims to know all the answers.  Beware of anyone telling you to stop asking questions.  RUN AWAY from anyone telling there are no new answers out there and we already know all we need to know.  They are Liars and con-artists and only seek to control you so they can line their pockets.  Find those among us who are kind, who seek new answers and new questions, who understand that, for all we know as humans, our knowledge is dwarfed by the vast amounts we do not know.  Lawrence M. Krauss has crafted an amazing book, one that not only tells us what we know and how, but informs us of what we have yet to find out.  I highly recommend it.

Italo Calvino Uses Words to Help Us Travel Through Deep Time

 


Cosmicomics – Italo Calvino (1965)

 

            I have read so many science fiction books and stories.  Many of their authors use specific scientific data or details to build stories around.  A few actually try to create stories that help the reader understand the scientific concepts discussed in the works.  Even fewer of those manage to create gripping, inventive stories.  Italo Calvino managed all of this and more.  What an amazing collection of short stories!

            I have been fortunate to discover many classic authors as part of my reading on this Book Journey.  From OG sci-fi writer Henry Kuttner, to modern author Cory Doctorow, I treasure finding their work and feeding my brain with their stories.  The one book I have read which most closely resembles Cosmicomics, however, is Clifton Fadiman’s Fantasia Mathematica, a collection of short stories from the 1950’s dealing with purely mathematical subjects.

            Italo Calvino takes the same approach with cosmology, specifically an exploration of the basic concepts used to describe the development of our Universe, from the Big Bang to the farthest reaches of deep time. His main narrator, inscrutably named Qfwfq, regales the reader with stories of his past, describing in beautiful allusions and metaphors, what the universe was like in the very first instances of existence.  In one story, he describes how the Moon used to be so close to the Earth that at certain points in the year, people would climb long ladders to reach the Moon, and harvest essential nutrition from it.  This is based on the knowledge that our Moon, Luna, is slowly moving away from the Earth.  In a million years, the Moon will be far smaller in our sky, and will not completely cover the Sun during eclipses.  In the far past, the Moon was much, much bigger than the Sun in our sky.

            In another great story, Italo’s narrator describes what it was like for him to exist as a creature who once lived in water, but is now on land, and all the accompanying weirdness!  One tale describes what the inner thoughts of fundamental particles must be like, while another shares the story of three entities forever falling through space and time.  Each tale is self-contained, but the whole collection truly helps expand the mind.  I found much wisdom in these stories.  The ancient poets created stories such as these to use as learning tools, handing them down orally to the next generation.  Mr. Calvino wanted to do the same with the often-misunderstood knowledge of Deep Time brought forth by Relativity and 20th century cosmology.

            Ancient scribes did likewise. These old stories were often misinterpreted or misunderstood by people of later generations.  Instead of seeking intellectual and informational wisdom in them, people started to see them as “divine” messages, or as dogmatic truth.  The very same thing could happen to Italo Calvino’s stories, should someone read them in two or three centuries, well after the average human forgets or is no longer taught basic scientific truths.  We seem to be headed in that direction now, sadly, and this blog, RXTT’s Book Journey, is my small attempt to forestall the stupidization of humanity.

            I must commend a Mr. William Weaver, who translated these stories into English around 1968.  The world owes so much to good translators.  It is almost as important a job as actually writing the books themselves!  Translation is how we can share ideas across cultures, continents, and centuries.

            I highly recommend this book to anyone with an interest in science fiction, mind expansion, originality, and creativity in storytelling.  It feels like something of a miracle that stories like this are available for us to read.  We are very fortunate indeed!

The Ancient Sumerians May Have Left Us Our True Legacy




The 12th Planet: Book I of the Earth Chronicles – Zecharia Sitchin (1976)


            I have always enjoyed my forays into what mainstream writers refer to as “the Fringe,” or, if they are being blunt, “the Lunatic Fringe.”  Ideas and subjects once considered ridiculous or plain deluded, have been shown throughout history to be valid, sometimes because it takes time for society to catch up to the ideas being described, and sometimes because what may come intuitively to a human being as a Truth cannot be verified until years or centuries later. 

An example of the former is Copernicus, whose writings were deemed heretical, solely because the mass consciousness at the time was living under a reality tunnel that did not allow for anything other than the will of a god to determine what happens to our world.  In a world rife with illiteracy, those who were literate and powerful (the church) controlled what the illiterates thought and believed.  An example of the latter would be Alfred Wegener, a meteorologist who, in the early 20th century, wrote up his ideas that the continental plates were in constant motion, and that the landmasses were all connected at one time in the distant past.  His ideas, while consistent with the observational data, were dismissed out of hand by geologists and earth scientists, who still believed the Earth was an unchanging rock, only altered by erosion and wind.  Once we humans began to create tools to explore the possibilities and history of plate tectonics, it was discovered that all the landmasses had indeed been connected in the past, and not just once, but at least 5 different times that can be verified through rock strata.  There are countless such examples.

I am not stating that what Mr. Sitchin describes in his book is factual, or even possible, but who am I to know?  I am just a well-read, educated reader, but in no way am I an expert on ancient cultures, especially the Sumerian kingdom, and what came before it.  What I do have experience with is reading about religion and myth and exploring how truth can be coded into legend, and how legends can betray truth when misread.  I say that as a caveat.  Mr. Sitchin studied the Hebrew Bible in the original Hebrew, and has studied the Greek early translations.  I am not sure if he has taught himself to read cuneiform and earlier writings, or if he is using other’s work, but I have to take all of his translations with a grain of salt.

That being said, what is described in this book is, to my mind, plausible, and a bit frightening if even slightly true.  There are some very serious and unanswered questions regarding the evolution of Homo sapiens, from the previous hominid species (Homo erectus, Homo neanderthalis, etc.) that immediately preceded our species.  The anthropological record seems to show that hominids evolved in Africa, and around 100,000 years or so ago (maybe longer), the ancestors of our species migrated out of Africa, settling in the Tigris-Euphrates valley and spreading through the world.  The earliest civilization that we can find any record of, whether archaeologically, or in ancient myths and writings, seemingly began out of nowhere around 8-10 thousand years ago, complete with agriculture, livestock, and societal structures we would recognize already in place.  This also coincided with the end of the last Ice Age on record.

Sitchin claims that the legends of Sumer and their tales of their gods are actually factual accounts retold as legendary history.  The 12th planet of the title, is supposed to be a planet on an inclined elliptical orbit of the Sun, taking it out way past Pluto, and then back into the Solar System, between Mars and Jupiter, every 6,400 or so years.  This planet was the home of beings that sought out the mineral riches of Earth for their benefit, and who settled down on our planet, building several cities in the Euphrates to serve as their “space port” in a way, for every one of their years afforded them a chance to return to Earth or return from Earth back home.

In this tale, the beings asked their lesser brethren to work on Earth, gathering the minerals (gold, lithium, plutonium) that they needed from the southern areas of Africa.  According to Sumerian myth, these workers got fed up and asked their leaders to create a race of beings to serve as their work slaves.  This was to be us, the humans.  Much is discussed about how the biblical story of creation seems to describe exactly such events, especially when the god of genesis describes how he is one of many gods, and how they created humans in the gods’ image.  Sitchin goes into a lot of detail regarding this, and it makes for very interesting reading.  Humans served the gods.  The gods watched over the humans.

In recent times, WWII air forces would set up temporary bases in secluded Pacific Ocean islands, bringing with them everything modern, and, once the usefulness of the island was gone, the Air Forces would leave.  The people who lived there, the native islanders who had very little, if any, knowledge of the world outside their islands, started very quickly to believe they were gods, who, if placated or inspired, would return, providing the islanders with the modern goods and luxuries they saw as nearly magical.  They would build effigies of WWII propeller fighter planes, and create landing strips, hoping to inspire the visitors to return again and grace them with their godly presence.  They stopped their native religious practices in the attempt to feed this new belief.  That is our human nature.  It is very plausible to me that if beings from another world ever came to our planet and interacted with us that we would see them as gods and build our entire culture around them.

There are a lot more examples and cool stories in this book.  While it may all be a writer-created hope, there is always the possibility that what Sitchin is describing is the truth of our existence.  Ancient man had deities that were eternal, always with us, always a part of the world around us.  In fact, the world itself was full of life spirit.  Modern man, however, created civilization, rigid religion, and the idea that the god/gods came once in our past, and will return again in the future.  This makes no sense if it was just a truth gathered by our experience in the world round us.  This makes more sense if we are collectively remembering a past in which humans were the subservient slaves of what seemed to us to be god-like beings.
 
This book is from 1976, and helped foster the Ancient Aliens hypothesis that I so deeply loathe.  (This states that the great works of humanity’s past were too hard for lowly ancient man, and must have been created by aliens, or with the help of aliens, etc.  This insults the brain of ancient man which was exactly like ours today.  If we can do something, they could have done it too.  The only difference is in our storehouse of aggregated knowledge that we can all build upon.)  What Sitchin proposes is not that aliens came down and helped humans, but that an alien race came down to Earth, genetically altered Homo erectus, and created what we call Homo sapiens.  This is why our upward mobility and societal structures have exponentially grown in the past 6,000 years, where before our ancestors were pleased enough to just chill in family groups, and enjoy their lives.  It is a crazy idea, but there have been far crazier ideas that have turned out to be correct.  Many of the criticisms I read about this book and Sitchin's work pertain to very specific instances of sections that critics state are mistranslated from the Sumerian language.  They outright dismiss any of the other claims in this book, without properly addressing them.  That is lazy criticism.  The jury is still out!

Quantum Gravity, and the history of human exploration into the nature of our Universe






Reality is Not What It Seems: The Journey Into Quantum Gravity – Carlo Rovelli (2014)

            Around a year ago I read and reviewed another book by the Italian physicist Carlo Rovelli.  (Click Here for that Review) That book was a detailed history of the man known as Anaximander, of whom I wrote that he is “the earliest human that we have record of who helped create the logical and rational framework that set the stage for the scientific revolution all humans have experienced over the past 250 years.”  At the time I bemoaned my inability to read his then-current book Reality is Not What It Seems.  Thank goodness for the good folks at the M.D. Anderson Library of the University of Houston.  They acquired the English translation and this is what I managed to stumble across during my browsing.

            Where to start?  This book is an attempt by Mr. Rovelli to discuss the history of our collective efforts to understand what constitutes the fabric of Reality, the elementary nature of our selves and everything that exists.  Beginning with Anaximander, Plato, and Aristotle, Mr. Rovelli describes how each of these ancient geniuses grappled with the substance of reality, and with the ability and limits of the human to comprehend this reality.  He details the amazing and near-miraculous insights from these men that propelled our entire world forward in the quest to understand. Leuccipus and Democritus formed the basis of “atomist” theory, purely through rigorous analytical thought, understanding that all matter is composed of small indivisible parts. Democritus alone was such an amazing thinker.  It is a shame most of his massive output has been lost to history.

            After the initial period of discovery, once monotheistic religions took over the human landscape, progress was effectively halted, and the knowledge of our forefathers was lost in the Western World.  Scientific fact was replaced by dogma and blind faith in the make-believe magic stories of priests and the governments which aligned themselves with religions.  It was after nearly a thousand years of barbaric ignorance that travelers and scholars visited India and brought back the wisdom of the ancient Greeks, knowledge which was critical to creating the modern world we all share.  From this influx of ancient wisdom and science, someone like Isaac Newton was able to understand and explain what he saw as the structure of the Universe.  Newton saw a fiercely deterministic static Universe.  His laws of motion and his invention of the Calculus allowed humans to plot star and planet trajectories centuries in advance, and his mathematics and science helped the Western world shake free of its religion-induced intellectual coma.

            The world as Newton saw it was un-changing, and infinite.  Scientists continued to study the Universe, finding and creating new tools with which to explore.  In the early 1900’s, Albert Einstein proceeded to shake the world to its core, much like Newton had done before.  Einstein understood that there is no static Universe and that everything is constantly in motion relative to everything else.  He was the first human to grasp that time is not a specific thing, existing separate from the Universe.  He saw that we live in an ever-expanding Present.  Einstein also saw that the world is not what Newton stated.  There is no matter and energy floating in empty space.  There is just matter and energy existing in space-time and gravity is merely the deformation of this space-time by massive objects.  All of these things have been verified countless times.

            What Einstein did for the world at large, quantum mechanics did for the world of the very small.  It is an extremely successful theory and its predictions have been validated countless times as well.  Quantum Mechanics shows us that the world is made up of quantum objects, which have probabilistic traits.  One cannot know everything about a proton, unlike in Newton’s time, when it was assumed that this was possible.  This indeterminacy has been proven to exist throughout the Universe at all quantum levels.

            All of this leads into the discussion of Quantum Gravity.  Einstein’s Relativity and quantum Mechanics work together in most ways, but in special cases, such as black holes, or singularities, both theories fall apart.  Gravity can only be calculated in the macro sense, and quantum effects never give definite answers.  To combine these two theories is the current goal of theoretical physicists around the world.  Some have been working on String Theory, which predicts the existence of super-symmetric particles.  These particles have not been seen in experiments at particle colliders.  This lends more weight to Rovelli’s field, which is studying Loop Quantum Gravity, which seeks to study the constituents of gravity, or the quanta of gravity. 

            Light acts as a wave and a particle.  The quanta of light is the Photon.  Gravity seems to act as both a wave and a particle, gravitational waves having been detected as recently as 2016.  Loop Quantum Gravity postulates that the smallest quanta of gravity are actually small closed “loops” as opposed to points.  He goes into a great explanation of his research and of the ways that scientists have arrived at this idea, one which seems to be more promising that String Theory. What a great book.  The Bibliography at the back will keep me happy for a while too.  I wish I could better describe how much is contained within this awesome book,  but you will have to read it for yourself.

G. Brent Dalrymple Provides a Great Tool to Fight the "Young Earth Creationist"





The Age of the Earth – G. Brent Dalrymple (1991)

            Back in the late 1970’s there began a series of challenges to the scholastic curriculum of schools in Alabama.  Certain religious idiots wished to force the school boards to devalue the teaching of natural selection, geology, and other science topics, while pushing the “alternate theories” of christian creationist bullshit that states the Earth and the Universe were all created sometime around 5,000-6,000 years ago (even though the nation-state of Egypt has been around for at least twice that long….morons.)  During this time Mr. Dalrymple was asked by the state if he could testify on the behalf of the science.  Mr. Dalrymple, being an eminent geophysicist and geologist, spent the better part of 5 months preparing, only to have the case be thrown out before it reached the courtroom.  Sadly, even more proudly ignorant people tried to do the same in other states, so Mr. Dalrymple saw that a need existed for a book that could explain the very many methods by which scientists have determined not only the approximate age of our planet Earth, but also the age of the Solar System, our Galaxy, and the Universe as a whole.

            A big part of how ignorant fundamentalists of every religious stripe manage to continue their assaults on everything good and decent in the world is their reliance on the lack of substantial scientific knowledge in the general American population.  Most US public schools teach the very basics of science, much of it severely outdated and archaic, but still needed as a foundation for what actual science is doing currently.  The problem lies in that schools are never given the chance to teach everything we currently now in the realms of science, as this is the purview of the Universities and their researchers.  This makes it very easy to fool people.  Make your false statements sound like actual science, and most people will assume it is.  It gives the backwards troglodyte religious-fundamentalist “humans’ among us a lot of joy to keep everyone ignorant.  If they are dumb as rocks, it makes it easy to feed them the lies that keep religions rich.  Believe me, all the religious leaders at the top KNOW their followers are blind idiots, sucking up whatever ”theology” the leaders wish to make the sheep believe.  They sit in their massive, lavish, extravagantly outfitted homes and offices and laugh and laugh and laugh….

            So, Mr. Dalrymple goes into great length to describe every aspect of how we know the ages of things.  He details what radioactivity is, what a “half-life” is, the methods used to test radioactivity, how they function, how we know they function, and what type of radiocarbon dating is good for what type of rock.  Each chapter then explains in exhaustive detail, sufficient for a learned expert, but still graspable by the lay reader, topics such as the age of the Earth based on modern geophysics and geology, the age of our Moon based on the rocks that humans have brought back, and then the age of the Universe itself, focusing on the data gathered from meteorites and interstellar debris we have collected.  In the hands of an educated person, this book could wholly rebuff any asshole trying to use make-believe fairy tales to keep young students ignorant.  This fight never ends, for ignorant fundamentalists will never change their mind, and they will go on indoctrinating their poor children in their backwards, regressive, baseless beliefs.

            The greatest aspect of science, and most scientists, is that they willingly accept the vast quantities of unknown information, without suffering from desperation.  Scientists understand that unexpected answers may point to new truth, a new area of study, or they may point to an old false belief, correcting what could be centuries of ill-informed assumptions.  The last chapter of this book details the many things we do not yet know about the age of the Earth and the Universe, much to its credit.  Scientists are always willing to concede what they do NOT know. The greatest fault in religious fundamentalists lies in that they assume without question that everything in the parts of the holy book they like are invariably and divinely true, and anything else is false.  They are so brainwashed that the world “gospel” in English has come to mean undisputed, unvarnished truth. So pathetic. Every single person that seeks to curtail a young child’s learning or that seeks to teach them patently erroneous fantasy instead of accepted scientific fact should be fought against vigorously.  It is wonderful that Mr. Dalrymple has provided at least one excellent weapon against these morons.
