1 WHAT DO WE REALLY KNOW ABOUT THE UNIVERSE? By David Prentice, M.Ed., M.A.S.T.
2 HOW DO YOU KNOW WHAT YOU KNOW? Or at least what you think you know?
3 WHAT MOST PEOPLE THINK: Evolution is science...Creation and Intelligent Designare religion.
4 EVOLUTION: Initial Disorganization with later increase in complexity and unlimited diversification.Not just change, but change in thedirection of increasing complexity.Simple to Complex.TIMEEvolutionary “Tree”All life came from one simple cell
5 CREATION: Initial Complexity with later deterioration and diversification within limits.Not just change, but change in thedirection of decreasing complexity.Complex to Simple.TIMECreationist “Forest”All life came from multiple complex ancestors.
6 WHAT DOES IT MEAN TO “KNOW” SOMETHING? 1. Personal Experiencethrough the five senses.I know a bee sting hurts;I know how to ride a bike.2. Reliance on Authority.I know the sun is 93million miles away;Jesus loves me, this I know,for the Bible tells me so.3. Logic.I know 2 million + 2 million =4 million, even though I’venever counted that high.I know I have a brain, eventhough I’ve never seen it.4. Feeling or Intuition.I know she’s the one forme; I know God has calledme to the ministry.6. Bluffing (lying) - you try to persuadeothers for an ulterior motive.You should buy these tickets from mebecause I know this team is goingto the Super Bowl this year;I know this car will give you yearsof faithful service!5. Wishful Thinking (youreally want it to be true)I just know I’m going towin the lottery!
7 THE SCIENTIFIC METHOD 1. Define the problem. What do you want to know? (E.g. “Does music affect how plants grow?”)2. Gather information about the subject.(AUTHORITY)3. Formulate a hypothesis.4. Devise a way to test the hypothesis.5. Observe the results of the test. (EXPERIENCE)6. Draw a conclusion (INDUCTIVE LOGIC) and reportyour results so others can repeat the test.
8 REASONS TO BELIEVE OTHERS WHO TRY TO PERSUADE US OF WHAT THEY “KNOW” IS IT BECAUSE:(1) They claim to have personal experience, OR(2) They appeal to an authority we trust, OR(3) We have checked out their logic andfound it trustworthy?OR are we willing to trust their (4) intuition,(5) wishful thinking, or (6) bluffing?
10 THE ORIGIN OF THE UNIVERSE: 1. No living person has personal experience.2. There are no eyewitness accounts except the Bible, which is unacceptable to skeptics.SO HOW DO WE “KNOW” ABOUT THE BEGINNING?Through LOGIC ONLY.
11 THE TWO TYPES OF LOGIC 1. INDUCTIVE. Look at many phenomena and try to discover a pattern that points to a general principle. Inductive logic tries to determine the most reasonable (most likely) conclusion.This is the heart of the scientific method.2. DEDUCTIVE.Start with general principles accepted as true and apply them to specific cases.Deductive logic tries to establish absolute truth, i.e., the conclusion MUST be true.
12 “SCIENCE” UNTIL THE MIDDLE AGES: Based on the deductive logic of the ancient Greeks,who believed that logic always leads to truth.Testing was unimportant to them.Most famous Greek philosopher:Aristotle (inventor of the logic still used today),whose ideas were taught as fact for about2,000 years throughout Europe,west Asia, and Africa.
13 EXAMPLES OF INCORRECT CONCLUSIONS BASED ON FAULTY LOGIC “Scientific” ideas of Aristotle TAUGHT AS FACT in European Universities for 2000 YEARS:1. The earth is the center of the solar system.Falsified by Copernicus.2. Heavier objects fall faster.Falsified by Galileo.3. All objects possess an innate tendency to come to rest.Falsified by Newton.
14 “PROVEN SCIENTIFIC FACT” Honest scientists will not claim to have absolutely proven ANYTHING (even the Law of Gravity!) using the scientific method.All we can legitimately say is that everytime we have observed something inthe past it’s always worked the sameway, so we expect that it will continueto work the same way in the future.
15 CONTRASTING LOGIC The conclusions of INDUCTIVE logic result from examination of observable phenomena(a posteriori). They are testable and open to modification.The premises of DEDUCTIVE logic may come from inductive conclusions, or they mayjust be statements accepted asself-evident (a priori). They arenot necessarily the result of testing.
16 THE ORIGIN OF THE UNIVERSE: There is no way to repeat the beginning of the universe. We have to look at circumstantial evidence to see what seems to be the most reasonable explanation.Anyone who claims to know absolutely what happened is not following inductive logic; they must be using DEDUCTIVE logic only.But can there be problems with deductive logic?
17 CONVERSES IN LOGIC If I am at Mount Everest, then I am at the highest mountain in the world.TRUE.THE CONVERSE:If I am at the highest mountain in the world,then I am at Mount Everest.ALSO TRUE.A converse is reliable ONLYif there is an exact one-to-one matchbetween the “If” and “Then” parts - a biconditional (“if and only if”).
18 INVALID LOGIC A converse is NOT reliable If I am at Victoria Falls,then I am at one of the largest waterfalls in the world.TRUE.THE CONVERSE:If I am at one of the largest waterfalls in the world,then I am at Victoria Falls.FALSE. (not reliable)A converse is NOT reliableif there is more than one possibility.

20 The Invalid Logic of Evolutionary Exclusivism If I am at Victoria Falls,then I am at one of the largest waterfalls in the world.TRUE.THE CONVERSE:If I am at one of the largest waterfalls in the world,then I am at Victoria Falls.FALSE. (not reliable)If evolution is true, then the universe and life would exist.TRUE.THE CONVERSE:If the universe and life exist, then evolution is true.FALSE. (not reliable)All teaching of “evolution only” in schools rests on theinvalid use of a logical converse.

23 EVEN WITH CORRECT LOGIC, FALSE PREMISES CAN LEAD TO FALSE CONCLUSIONS. All dogs bark. (Or, “If an animal is adog, then it barks.”)Fido is a dog.Therefore, Fido barks.NotifFidoisaBasenji!Basenjisdonotbark.If any one of our premises is wrong, then our conclusion is unreliable.
24 POSTULATES - Statements that are taken as self-evident and accepted without proof. Euclid’s Parallel Line Postulate says that for any line, there can be only one parallel line through a point not on the first line.Point not on the first lineOnly one parallel lineFirst lineBUT IS IT REALLY SELF-EVIDENT?Lobachevskyan and Riemannian geometry say that space is curved,so there is no such thing as an infinitely long straight line in thesense that we understand “straight.”One says space is negatively curved so that there are an infinite number of parallel lines through a point not on a line.The other says space is positively curved so there are no parallel lines. All linesintersect at infinity.EACH OF THE THREE IS THE BASIS OF A DIFFERENTVERSION OF GEOMETRY, BUT NONE CAN BE PROVEN.
25 BASIC PREMISES OF EVOLUTION AND CREATION 1. Everything must be explainable by purely natural processes.a. Atheistic evolution: There is no God.b. Theistic evolution: Since the Big Bang,God’s involvement with nature hasbeen trivial.Known as either NATURALISM,MATERIALISM, OR ATHEISM.A supernatural intelligence created the universe. Though most things are explainable by natural processes, some things may not be.This is as far as Intelligent Design goes. (The intelligence could be the Flying Spaghetti Monster!) Creation specifies that the intelligence is God.LIKE THE POSTULATES OF GEOMETRY, NEITHER SET OF PREMISES CAN BE PROVEN. THEY MUST BE ACCEPTED BY FAITH AS SELF-EVIDENT.
26 MATERIALISM: NO GOD ALLOWED! "We take the side of science in spite of the patent absurdity of some of its constructs, in spite of the failure to fulfill many of its extravagant promises of health and life, in spite of the tolerance of the scientific community for unsubstantiated just-so stories,because we have a prior commitment, a commitment tomaterialism.materialism. It is not that the methods and institutions of science somehow compel us to accept a material explanation of the phenomenal world, but, on the contrary, that we are forced by our a priori adherence to material causes to create an apparatus of investigation and a set of concepts that produce material explanations, no matter how counterintuitive, no matter howmystifying to the uninitiated.Moreover, that materialism is an absolute, for we cannot allow a Divine Foot in the door."Richard Lewontin, The New York Review, Jan. 1997
27 NECESSARY CHARACTERISTICS GOD1. Only seen by what He does -INVISIBLE.2. Established natural laws, sois not subject to those laws -SUPERNATURAL.3. Preceded the universe -ETERNAL.4. Influence extends throughoutthe universe - OMNIPRESENT.5. Directly or indirectly responsi-ble for everything that has everhappened - OMNIPOTENT.6. Nobody made Him - SELF-EXISTENT.
28 IF THERE IS NO GOD, THEN WHAT? What if there is no God? Then the universe would have to be the result of a series of forces, processes, and events operating with no particular purpose for billions of years.We could call the whole series “evolution,” “quantum fluctuation,” or “accident.” Let’s use the term “Random Chance,” with the understanding that it represents the whole multibillion year series of forces, processes, and events.Let’s see the characteristics that Random Chance would have to have.

30 IS ALL TRUTH SCIENTIFICALLY PROVABLE? Okay, prove scientifically that you love your husband / wife / mother etc.Likewise, our inability to prove there is a God does not mean He does not exist;our inability to prove there is not a God does not mean He does exist.
31 WHAT MOST PEOPLE THINK: Evolution is science...Creation and Intelligent Designare religion.But in what way is believing in the IMPOSSIBILITY of Intelligent Designany more scientific than believing in thePOSSIBILITY of Intelligent Design?Either way it’s a matter of philosophy, not science.
32 BASIC PREMISES OF EVOLUTION AND CREATION 1. Everything must be explainable by purely natural processes.a. Atheistic evolution: There is no God.b. Theistic evolution: Since the Big Bang,God’s involvement with nature hasbeen trivial.1. A supernatural intelligence created the universe. Though most things are explainable by natural processes, some things may not be.2. Since there could be no other naturalprocesses besides evolution, evolutionis the only possibility.2. God is powerful enough to use any method he chooses, including instantaneous creation.LIKE THE POSTULATES OF GEOMETRY, NEITHER SET OF PREMISES CAN BE PROVEN. THEY MUST BE ACCEPTED BY FAITH AS SELF-EVIDENT.
33 EVOLUTION: Natural Processes Only! “... the theory of evolution itself [is] a theory universally accepted not because it can beproved by logically coherent evidence tobe true but because the only alternative,special creation, is clearly incredible.”D.M.S. Watson, “Adaptation,” Nature, Vol. 123 (1929), p.233"Even if all the data point to an intelligentdesigner, such a hypothesis is excluded from science because it is not naturalistic."Immunologist Scott C. Todd in a letter to Naturemagazine, Sept. 1999
34 How many non-barking dogs does it take to show that maybe Fido doesn’t bark? This is why materialists fight so hard against Intelligent Design. If there is even one thing that can’t be explained by natural processes, then their fundamental premise is false!

39 WHAT DO WE REALLY KNOW ABOUT THE UNIVERSE? So, back to our first question:WHAT DO WE REALLY KNOW ABOUT THE UNIVERSE?
40 THE SCIENTIFIC METHOD 1. Define the problem. What do you want to know? (E.g. “Does music affect how plants grow?”)2. Gather information about the subject.(AUTHORITY)3. Formulate a hypothesis.4. Devise a way to test the hypothesis.5. Observe the results of the test. (EXPERIENCE)6. Draw a conclusion (INDUCTIVE LOGIC) and reportyour results so others can repeat the test.
41 Things to Which We Can Directly Apply the Scientific Method: Phenomena we can directly observe and test.Chemical composition or magnetic fields of bodies in the solar system. We can analyze either by close flybys or actual landings.Positions and motions of planets, moons, etc. – direct telescope observation.Radiation output, etc. – direct measurements.Distance to stars up to about 50 light years away – calculated by parallax.Chemical composition of the photosphere of sun and stars – spectroscopic analysis.
42 SPECTROSCOPIC ANALYSIS Each element’s unique arrangement of electrons produces a pattern (spectrum) of colored lines as its electrons jump between higher and lower energy levels. Lines are bright as the electrons emit energy or dark as they absorb it.Above: Black and white graph of the spectrum of hydrogen.Below: Emission spectra of three common elements showing colors.Emission spectrum of HydrogenEmission spectrum of FluorineEmission spectrum of Oxygen
43 HOW DO WE KNOW WHAT’S IN A STAR? • In a laboratory, we see an emissionspectrum of bright lines against adark background.• However, the interior of a star is so hot that the electrons are knocked completely away from the atoms. (This is called a plasma.) The star’s light is NOT from electrons jumping between specific energy levels, so it is a continuous white light.• Light from the interior must pass through the star’s outer regions (its photosphere) on its way to us. This part of the star is not as hot, so some of the atoms do have electrons.• These electrons absorb specific colors as they move to higher energy levels.• What we see on earth is like a pho-tographic negative. Instead of anemission spectrum of bright linesagainst a dark background, we see an absorption spectrum of dark lines against a bright background. This enables us to identify elements present in the star’s outer layers.
44 Things We Cannot Legitimately be as Confident About: Phenomena for which we have indirect data, but we cannot directly observe and test.Interior structure of stars and planets. Since we cannot directly see inside we devise models. However, we must recognize that the models may need to be revised.Meaning of anomalous red shifts. We directly measure the shifts, but we must then interpret what they mean. Are all red shifts due to linear motion? Could gravitational / relativistic red shifts be involved?Presence of planets around distant stars. We measure a tiny amount of “wobble” in the starlight, which we then interpret to mean that an orbiting object is pulling the star. Are there other possibilities?
45 Possible Explanations for “Wobble” of Starlight Red Shift VariesBROWN DWARF IN ORBITMEASURE-MENT ERRORSPLANETIN ORBITPULSATION OF STARUNKNOWN FACTORSCan we be absolutely certain?
46 THINGS WE CANNOT TEST (Deductive Logic Only): Phenomena we cannot directly observe, for which we devise models that we also cannot directly test.Origin of the matter and energy that comprise the universeUnderlying geometry of the universeAge of the universeMechanisms involved in a Big BangMechanisms of galaxy and cluster formationOrigin of the solar system and its parts
47 We need to explain the origin of the 90 naturally occurring elements.

Elements 43, 61, and 93 and above (shown in red) are known only in artificially manufactured form, though #43 is seen in some stars.We need to explain the origin of the 90 naturally occurring elements.
48 Naturally Occurring Isotopes Name of Isotope Atomic Number Mass Number Protons NeutronshydrogenhydrogenhydrogenheliumheliumNONEXISTENT 5lithiumlithiumNONEXISTENT 8berylliumboronboroncarboncarboncarbonnitrogennitrogenoxygenoxygenoxygenetc.A Big Bang could not produce any element heavier than Lithium.
49 WHY SUCH A BIG DEAL?Somewhere around 99% of the observed matter in the universe consists of H-1 and He-4. There are only afew possible ways to combine two of these atoms.• Two H-1 nuclei (two protons) cannot stay together without the presence of at least one neutron. (There is no such thing as He-2.) Even then, He-3 comprises only % of the Helium known.• A H-1 and He-4 nucleus together would have mass 5. Oops, it doesn’t exist either.• Two He-4 nuclei would have a mass of 8, but that doesn’t exist either.A Big Bang would have expanded too fast to combine morethan two particles at a time, and there are no other com-binations of two. We are blocked at every turn whentrying to make heavier elements out of the twoelements that would have been present in a Big Bang.
50 Problems with Synthesis of Heavier Elements in Stars Once all the hydrogen in the core of a star is used up, the star is supposed to experience a “helium flash” in whichit suddenly fuses two helium nuclei into Be-8, three intoC-12 (“triple-alpha”), and four into O-16.THREE PROBLEMS:(1) Be-8 decays instantaneously and would be unavailable as a building block for heavier elements.(2) The process has never been seen. Even if it did occur, it would be undetectable. There is no evidence that it has ever happened. It is an a priori assumption needed for materialistic evolution to be true.(3) Atomic nuclei are so tiny that the chance is extraordinarily small for two to collide, let alone three or four.
51 Problems with Synthesis of Heavier Elements in Supernovae Supernovae are believed to reach temperatures thousands of times hotter than normal, high enough to synthesize the rest of the elements. These elements are supposedly flung into space, then recycled into new stars.TWO PROBLEMS:(1) The earliest stars should have been composed of nothing but hydrogen and helium. However, we have never seen a single metal-free star, even among the very “oldest” ones.(2) Since gravity drops off by the square of the distance between objects, it would be far too weak to pull the parts back together into a new star. The material should just float through space. No evidence here either - just a desire to have materialistic evolution be true!
52 IS EVOLUTION FALSIFIABLE? The most fundamental assumption of evolution is that everything must be explainable by purely natural processes.But what if something can’t be explained by natural processes?YES IT CAN!We make up a story then use faulty logic to say,“Because we can make up a story, therefore our story must be true.”The Story of the Supernovae and the ElementsOnce upon a time there was a big supernova. It produced many atoms of heavy elements, but they were spreading throughout space. Then a second supernova took place light-years away. The shock wave from the second supernova traveled trillions of miles and pushed the expanding cloud from the first supernova back together into a ball. It became a new star that now had heavier elements. The process repeated over and over, spreading heavy elements to every single star we’ve ever seen.The End.Do you believe that a shock wave from trillions of miles away canmake an expanding cloud collapse into a ball? Do you believeevery observable star in the universe would be affected?

54 OCCAM’S RAZOR: “Entities Should Not Be Multiplied Beyond Necessity.” A principle of logic that can be paraphrased as,“The simplest explanationthat fits all the factsis usually the best.”Not a hard and fast rule, but a good guideline. The fewer stories you have to make up, the better.(K.I.S.S.!)
55 A Priori Assumptions of Materialistic Cosmology 1. Everything must be explainable by purely natural Processes.a. Atheistic evolution: There is no God.b. Theistic evolution: Since the Big Bang, God has had littleinvolvement with nature.2. The earth cannot occupy any special place in the universe. (The Cosmological Principle)3. In order to explain the earth’s apparent position somewhere near the center of the universe, space must not be three-dimensional. It is four-dimensional and curves back on itself.4. Four-dimensional space has no center or edge. It is unbounded.5. Space is defined by the presence of matter. Where there is no matter, there is no space.None of these is provable. They are accepted as self-evident.
56 • • • • Classical Physics - Euclidean Geometry Relativity - Non- Euclidean GeometryB•B••A•AThe universe does not expand through 3-dimensional space because the universe is space. There is no “outside” because “outside” indicates a place in space, which does not exist past the edge of the expanding universe. Space expands, but points A and B keep their same relative positions.According to classical physics,if the universe expanded it did sothrough three-dimensional space. Points A and B move apart through space.
57 FOUR DIMENSIONAL SPACE Space is curved, but we can’t detect it. Imagine a 2-dimensional ant trapped inside the surface of a piece of paper. He has no concept of “up” or “down.” Even if the paper is curved into a sphere, he has no way to know it because he can only seehis immediate area.Big Bang cosmology says that we are the ants, but we don’t know it because we are trapped inside the 3-dimensional surface of a 4-dimensional “hypersphere.”Space is curved, but we can’t detect it.
58 UNBOUNDED SPACEA 2-dimensional ant confined to the surface of a sphere couldnever reach the center or the edge because fromhis perspective the surface has no centeror edge. To him, it is unbounded.If space is a dimensionalhypersphere, we are confinedto its 3-D surface. We cannever find the center or the edgebecause neither exists. 4-D spacewould have to be unbounded.
59 THE COSMOLOGICAL PRINCIPLE No matter where the ant goes, things look pretty much thesame in any direc tion. There is noreferred frame of reference.Likewise, Big Bang theoryassumes that no matter wherein space we go, things on alarge enough scale will lookpretty much the same inany direction.This is philosophy, not science. Ifthere is a preferred frame of reference,the big bang and some (not all!) parts of the theoryof relativity are wrong.
60 2 Types of Evidence Used to Support the BIG BANG: of StarlightRed Shift2. Cosmic Microwave Back-ground Radiation (CMB)
61 Actual wavelength of star’s light Normal absorption spectrum SO WHAT’S A “RED SHIFT”?Reports of the universe expanding are based on colors (wavelength) of light from stars shifted toward the red end of the spectrum. Almost all astronomers interpret this as a Doppler shift due to the stars moving away from us.Actual wavelength of star’s lightNormal absorption spectrumSeemingly stretched-out wavelength due to motion away from us - exaggerated for purpose of illustration“Red-Shifted”absorption spectrumSeemingly compressed wavelength due to motion toward us - exaggerated for purpose of illustration“Blue-Shifted”absorption spectrum
62 Possible Explanations for Red Shifts GRAVITA-TIONAL EFFECT Red Shift ExistsDOPPLER EFFECTGRAVITA-TIONAL EFFECTTRANSVERSE EFFECTRELATIVISTIC EFFECTUNKNOWN FACTORSWould we even know how to interpret a Doppler shift if space is four-dimensional?
63 QUASARS: A BIG LITTLE PROBLEM! Quasars are extremely bright, but their rapid pulsation indicates that they are relatively small. Because of their high red shifts, they are believed to be among the most distant objects in the universe.The Stefan-Boltzmann law says energy output is proportional to an object’s surface area and the fourth power of the temperature.There is no known way an object as small as a quasar could gethot enough to be so bright if it is really billions of light years away.NASA photos of a quasar supposed to be 1.5 billion light years awayEither we are wrong about the Stefan-Boltzmann law, derived from observation, or else we are wrong about the meaning of red shifts for at least these quasars. How can we be sure about the meaning of red shifts for anything, then?
64 QUANTIZED RED SHIFTSIf the universe is the result of a Big Bang, then starsand galaxies near us should have very low redshifts, while those far away should have high shifts.For objects in between, there should bea continuous distribution of red shifts.THERE IS NOT.Red shifts occur in discrete intervalscalculated at about 72 km/sec.Evolutionary astronomy hasno explanation for this phenomenon.Some Intelligent Design advocates point out that the quantization of red shifts would make sense if the earth were near the center of a 3-dimensional(non-Big Bang) universe.
65 QUANTIZED RED SHIFTS • • This is exactly what we see. If the universe expanded uniformlythrough 3-dimensionalspace, an observer notnear the center wouldsee a continuousrange of red shiftsdetermined by thedistance of each galaxy emitting light. About 2 million light years from the center, the distribution of red shifts should look something like this:However, an observernear the centerwould see redshifts in dis-crete intervals.The distributionwould look some-thing like this:••Distance in M Light YearsNumber of Galaxies105Distance in M Light YearsNumber of Galaxies105This is exactly what we see.It looks like the earth is near the center of the universe!
66 A CHALLENGE TO MATERIALISM: Come up with an alternate explanation for the quantization of red shifts.
67 2 Types of Evidence Used to Support the BIG BANG: of StarlightRed Shift2. Cosmic Microwave Back-ground Radiation (CMB)
68 Energy Level of the CMB The present energy level of the CMB is about 2.73 degrees above absolute zero.• At the time of the Big Bang, theory says that the temperature would have been billions of degrees. Matter and energy would have been freely changing back and forth.• As the fireball expanded, the matter and energy would have cooled like the gases in a refrigerator.• After 300,000 years matter and energy would have “decoupled” so that the energy went right through matter without affecting it.• The energy level of the radiation would have been about 3000K at the time.• In order to explain the change from 3000K to 2.73K, we have to say that the energy was absorbed by the fabric of space as it expanded.This, too, requires expanding 4-dimensional space.It is not possible in 3 dimensions.
69 Distribution of the CMB Computer generated image of cosmic microwave backgroundradiation released by NASA in 1992 based on COBE data.The image is deceptive. The “hot spots” are greatly exaggerated due to computer manipulation. The CMB is almost perfectly uniform, to within 30 parts per million.
70 A Possible Factor in the CMB: Blackbody Radiation Wavelength distrib ution of the CMB, degrees above absolute zero. (Based on COBE data.)Under laboratory conditions, such a distribution usually indicates “blackbody radiation” caused by objects emitting energy at the same rate they absorb it. Could space dust be contributing to the CMB?
71 at 1020 times the speed of light and lumps formed. INFLATIONARY MODELTo account for the “Horizon Problem” – the discrepancy between the smooth background radiation and the “lumpy” distribution of matter -- many believe that there was an inflationary period between and sec-onds after the Big Bang during which space expandedat 1020 times the speed of light and lumps formed.This is incompatible with the Law of Conservation of Momentum and Newton’s 2nd Law of Motion. There is no known physical cause for the expansion to speed up and then slow down again -- only an a priori assumption needed for the Big Bang to be correct.Inflation is also insufficient to account for the amount of clustering observed. With the amount of matter known in the universe, it would take 60 billion years to reach the present level. (Hence, the invention of “dark matter.”
72 Isn’t the Scientific Method supposed to be based on OBSERVATION? COLD DARK MATTERThere is nowhere near the amount of matter needed to pull together galaxies, galaxy clusters, and so on.In order to hold to materialistic Big Bang cosmology, we have to believe that 90 to 99% of the matter in the universe is invisible.As alternatives, some have proposed String and Texture theories. These depend on the existence of “Higgs Fields,” hypothetical force fields that appear and disappear as necessary to make the mathematics of a Big Bang work.Isn’t the Scientific Method supposed to be based on OBSERVATION?

74 Conservation of Angular Momentum Any rotating object possesses a property known as angularmomentum. As the object’s diameter increases, itsspeed of rotation decreases in order to conserve angu-lar momentum. As the diameter decreases, thespeed increases.Suppose a galaxy were only a billion miles indiameter, and rotating at only one mile per hour.If we move back through time toward the Big Bang, itmust have been smaller and smaller. Since it had all itsangular momentum from the beginning, it had to berotating faster and faster. At some point shortlyafter the Big Bang, it would have had to be rotating farfaster than the speed of light.According to the observations of physics,this is a physical impossibility.
75 PROBLEMS WITH “LITTLE BIG BANGS” If there were several “little big bangs” that interacted with each other, this could overcome the problems of conserva-tion of linear momentum and angular momentum. However,1. Each singularity would be the result of a quantum fluctua-tion. The results of such fluctuations should be random and unpredictable. Yet we see the same types of matter and energy everywhere we look throughout the universe.2. The Big Bang says that there was nothing outside the explo-sion, not even space. Space is 4-dimensional. However, “Little Big Bangs” would have occurred at many different locations, meaning that space already existed before they exploded. Space would have to be 3-dimensional.3. We must discard the First Law of Thermodynamics over and over, each time one of the smaller singularities appeared.
76 The Most Fundamental A Priori Assumption of Materialistic Cosmology: Everything must be explainable by purely natural Processes.But there are no KNOWN natural processes that might have produced matter and energy, or that might have caused the singularity to explode, or that might have caused inflation, or that might have caused clustering, etc.We can choose to believe in unknown NATURAL processes, or unknown NON-NATURAL processes.Either way, it’s a step of faith!
77 HOW ABOUT THE SOLAR SYSTEM? Can we explain its origin by known natural processes?
78 COMPOSITION OF THE PLANETS The standard scenario for the origin of the sun and planets is the collapse of a planetary disk. If this is the case, the chemical composition should be similar throughout the solar system.MercuryVenusEarthMarsSaturnJupiterNeptuneUranusHowever, NASA space flights tell us that each planet is made of a mix of elements different from all the rest and from the sun.This is incompatible with the “planetary disk” hypothesis.
79 ANGULAR MOMENTUMThe sun possesses 99% of the mass in the solar system, yetthe planets possess 98% of the angular momentum.MercuryVenusEarthMarsJupiterSaturnNeptuneUranusThere is no known way that a rotating disk of gas and dusk could distribute its angular momentum so unevenly.This, too, is incompatible with the “planetary disk” hypothesis.
80 This, too, is incompatible with the “planetary disk” hypothesis. ORBITS OF THE PLANETSEach of the planets orbits the sunin a different plane.• Pluto, Mercury, and earth’s “twin,” Venus, are themost inclined with respect to our own orbit.• Venus rotates backward from the rest; Uranus rotates almost perpendicular to its orbit.• At least 11 moons orbit opposite their mother planet’s rotation.• The moons of Uranus orbit almost perpendicular to the rest of the solar system.This, too, is incompatible with the “planetary disk” hypothesis.
81 COULD THE PLANETS HAVE BEEN CAPTURED BY THE SUN’S GRAVITY? Suppose you had a turn-table with a magnetat the center andnine individual-ly adjustablerotating rings.Could you rolla steel ballbearing ontothe turntableand get it to or-bit by exactlybalancing the mag-netic force with theoutward momentum?Got one in orbit? Nowdo it 8 more times,one for each pla-net, without dis-turbing thefirst ball.Got your 9planets inplace? Nowdo it about 4dozen moretimes, one foreach moon.BUTWAIT! You have to do itin 3 dimensions, not two!Even with all our technology, there is no way we could put together an arrangement as complex as the solar system. Yet it is supposed to be the product of Random Chance.
82 WHAT DO WE REALLY KNOW ABOUT THE UNIVERSE? Back to our first question:WHAT DO WE REALLY KNOW ABOUT THE UNIVERSE?Not very much! Most of what we think we know is deductive logic, based on a priori assumptions.Are you willing to examine your assumptions to see if they make sense?
