How the WMAP satellite confirmed nucleosynthesis predictions and falsified atheism

Apologetics and the progress of science
Apologetics and the progress of science

Prior to certain scientific discoveries, most people thought that the universe had always been here, and no need to ask who or what may have caused it. But today, that’s all changed. Today, the standard model of the origin of the universe is that all the matter and energy in the universe came into being in an event scientists call “The Big Bang”. At the creation event, space and time themselves began to exist, and there is no material reality that preceded them.

So a couple of quotes to show that.

An initial cosmological singularity… forms a past temporal extremity to the universe. We cannot continue physical reasoning, or even the concept of spacetime, through such an extremity… On this view the big bang represents the creation event; the creation not only of all the matter and energy in the universe, but also of spacetime itself.

And another quote:

[A]lmost everyone now believes that the universe, and time itself, had a beginning at the big bang.

So, there are several scientific discoveries that led scientists to accept the creation event, and one of the most interesting and famous is the discovery of how elements heavier than hydrogen were formed.

Here’s the history of how that discovery happened, from the National Aeronautics and Space Administration (NASA) web site:

The term nucleosynthesis refers to the formation of heavier elements, atomic nuclei with many protons and neutrons, from the fusion of lighter elements. The Big Bang theory predicts that the early universe was a very hot place. One second after the Big Bang, the temperature of the universe was roughly 10 billion degrees and was filled with a sea of neutrons, protons, electrons, anti-electrons (positrons), photons and neutrinos. As the universe cooled, the neutrons either decayed into protons and electrons or combined with protons to make deuterium (an isotope of hydrogen). During the first three minutes of the universe, most of the deuterium combined to make helium. Trace amounts of lithium were also produced at this time. This process of light element formation in the early universe is called “Big Bang nucleosynthesis” (BBN).

The creation hypothesis predicts that there will be specific amounts of these light elements formed as the universe cools down. Do the predictions match with observations?

Yes they do:

The predicted abundance of deuterium, helium and lithium depends on the density of ordinary matter in the early universe, as shown in the figure at left. These results indicate that the yield of helium is relatively insensitive to the abundance of ordinary matter, above a certain threshold. We generically expect about 24% of the ordinary matter in the universe to be helium produced in the Big Bang. This is in very good agreement with observations and is another major triumph for the Big Bang theory.

Moreover, WMAP satellite measurements of mass density agree with our observations of these light element abundances.

Here are the observations from the WMAP satellite:

Scientific observations match predictions
Scientific observations match predictions

(Source)

And here is how those WMAP measurements confirm the Big Bang creation event:

However, the Big Bang model can be tested further. Given a precise measurement of the abundance of ordinary matter, the predicted abundances of the other light elements becomes highly constrained. The WMAP satellite is able to directly measure the ordinary matter density and finds a value of 4.6% (±0.2%), indicated by the vertical red line in the graph. This leads to predicted abundances shown by the circles in the graph, which are in good agreement with observed abundances. This is an important and detailed test of nucleosynthesis and is further evidence in support of the Big Bang theory. 

“An important and detailed test”.

For completeness, we should learn how elements heavier than these light elements are formed:

Elements heavier than lithium are all synthesized in stars. During the late stages of stellar evolution, massive stars burn helium to carbon, oxygen, silicon, sulfur, and iron. Elements heavier than iron are produced in two ways: in the outer envelopes of super-giant stars and in the explosion of a supernovae. All carbon-based life on Earth is literally composed of stardust.

That’s a wonderful thing to tell a young lady when you are on a date: “your body is made of stardust”. In fact, as I have argued before, this star formation, which creates the elements necessary for intelligent life, can only be built if the fundamental constants and quantities in the universe are finely-tuned.

Now, you would think that atheists would be happy to find observations that confirm the origin of the universe out of nothing, but they are not. Actually, they are in denial.

Here’s a statement from the Secular Humanist Manifesto, which explains what atheists believe about the universe:

Religious humanists regard the universe as self-existing and not created.

For a couple of examples of how atheistic scientists respond to the evidence for a cosmic beginning, you can check out this post, where we get responses from cosmologist Lawrence Krauss, and physical chemist Peter Atkins.

You cannot have the creation of the universe be true AND a self-existing, eternal universe ALSO be true. Someone has to be wrong. Either the science is wrong, or the atheist manifesto is wrong. I know where I stand.

Positive arguments for Christian theism

Does the word atheism mean “a lack of belief in God”?

Making sense of the meaning of atheism
Making sense of the meaning of atheism

First, let’s see check with the Stanford University Encyclopedia of Philosophy.

Excerpt:

‘Atheism’ means the negation of theism, the denial of the existence of God.

Stanford University is one of the top 5 universities in the United States, so that’s a solid definition. To be an atheist is to be a person who makes the claim that, as a matter of FACT, there is no intelligent agent who created the universe. Atheists think that there is no God, and theists think that there is a God. Both claims are objective claims about the way the world is out there, and so both sides must furnish forth arguments and evidence as to how they are able to know what they are each claiming.

Philosopher William Lane Craig has some thoughts on atheism, atheists and lacking belief in God in this reply to a questioner.

Question:

In my discussions with atheists, they  are using the term that they “lack belief in God”. They claim that this is different from not believing in God or from saying that God does not exist. I’m not sure how to respond to this. It seems to me that its a silly word-play and is logically the same as saying that you do not believe in God.
What would be a good response to this?
Thank you for your time,

Steven

And here is Dr. Craig’s full response:

Your atheist friends are right that there is an important logical difference between believing that there is no God and not believing that there is a God.  Compare my saying, “I believe that there is no gold on Mars” with my saying “I do not believe that there is gold on Mars.”   If I have no opinion on the matter, then I do not believe that there is gold on Mars, and I do not believe that there is no gold on Mars.  There’s a difference between saying, “I do not believe (p)” and “I believe (not-p).”   Logically where you place the negation makes a world of difference.

But where your atheist friends err is in claiming that atheism involves only not believing that there is a God rather than believing that there is no God.

There’s a history behind this.  Certain atheists in the mid-twentieth century were promoting the so-called “presumption of atheism.” At face value, this would appear to be the claim that in the absence of evidence for the existence of God, we should presume that God does not exist.  Atheism is a sort of default position, and the theist bears a special burden of proof with regard to his belief that God exists.

So understood, such an alleged presumption is clearly mistaken.  For the assertion that “There is no God” is just as much a claim to knowledge as is the assertion that “There is a God.”  Therefore, the former assertion requires justification just as the latter does.  It is the agnostic who makes no knowledge claim at all with respect to God’s existence.  He confesses that he doesn’t know whether there is a God or whether there is no God.

But when you look more closely at how protagonists of the presumption of atheism used the term “atheist,” you discover that they were defining the word in a non-standard way, synonymous with “non-theist.”  So understood the term would encompass agnostics and traditional atheists, along with those who think the question meaningless (verificationists).  As Antony Flew confesses,

the word ‘atheist’ has in the present context to be construed in an unusual way.  Nowadays it is normally taken to mean someone who explicitly denies the existence . . . of God . . . But here it has to be understood not positively but negatively, with the originally Greek prefix ‘a-’ being read in this same way in ‘atheist’ as it customarily is in . . . words as ‘amoral’ . . . . In this interpretation an atheist becomes not someone who positively asserts the non-existence of God, but someone who is simply not a theist. (A Companion to Philosophy of Religion, ed. Philip Quinn and Charles Taliaferro [Oxford:  Blackwell, 1997], s.v. “The Presumption of Atheism,” by Antony Flew)

Such a re-definition of the word “atheist” trivializes the claim of the presumption of atheism, for on this definition, atheism ceases to be a view.  It is merely a psychological state which is shared by people who hold various views or no view at all.  On this re-definition, even babies, who hold no opinion at all on the matter, count as atheists!  In fact, our cat Muff counts as an atheist on this definition, since she has (to my knowledge) no belief in God.

One would still require justification in order to know either that God exists or that He does not exist, which is the question we’re really interested in.

So why, you might wonder, would atheists be anxious to so trivialize their position?  Here I agree with you that a deceptive game is being played by many atheists.  If atheism is taken to be a view, namely the view that there is no God, then atheists must shoulder their share of the burden of proof to support this view.  But many atheists admit freely that they cannot sustain such a burden of proof.  So they try to shirk their epistemic responsibility by re-defining atheism so that it is no longer a view but just a psychological condition which as such makes no assertions.  They are really closet agnostics who want to claim the mantle of atheism without shouldering its responsibilities.

This is disingenuous and still leaves us asking, “So is there a God or not?”

So there you have it. We are interested in what both sides know and what reasons and evidence they have to justify their claim to know. We are interested in talking to people who make claims about objective reality, not about themselves, and who then go on to give reasons and evidence to support their claims about objective reality. There are atheists out there that do make an objective claim that God does not exist, and then support that claim with arguments and evidence. Those are good atheists, and we should engage in rational conversations with them. But clearly there are some atheists who are not like that. How should we deal with these “subjective atheists”?

Well, my advice is to avoid them. They are approaching religion non-cognitively. When you engage in serious discussions with people about God’s existence, you only care about what people know and what they can show to be true.

Brian Auten interviews J. Warner Wallace of ColdCaseChristianity.com

J. Warner Wallace: God's Crime Scene
J. Warner Wallace: God’s Crime Scene

I spotted this on Apologetics 315.

The MP3 file is here. (43 minutes)

Details from Brian’s post:

Today’s interview is with Jim Wallace of PleaseConvinceMe.com and host of the PleaseConvinceMe Podcast. As a cold case detective, Jim brings a unique perspective to his approach to apologetics and a very down-to-earth logical style. In this interview, Jim talks about his approach to the evidence (inference to the best explanation), Tactics and apologetics, debate vs. dialogue, pitfalls to apologists, and more.

Topics:

  • Jim’s background as an Catholic-raised atheist, and cold-case detective
  • Jim believed in the progress of science to answer all the unresolved questions
  • How did Jim become an atheist?
  • Why didn’t Jim respond to Christians witnessing to him without evidence?
  • What approach worked to start him thinking about becoming a Christian?
  • What did Jim do to grow as a Christian?
  • How did Jim’s police training help him to investigate Christianity?
  • What investigative approach is used in his police work?
  • Does “abductive reasoning” also work for investigating Christianity?
  • What sort of activities did Jim get involved in in his community?
  • How Jim’s experience as a youth pastor convinced him of the value of apologetics
  • How young people learn best by training for engagement with opponents
  • How Jim takes his youth on mission trips to UC Berkeley to engage the students
  • Is it possible to run an apologetics ministry part-time while keeping a day job?
  • Do you have to be an expert in order to have an apologetics ministry?
  • What books would Jim recommend to beginning apologists?
  • How the popular apologist can have an even bigger impact than the scholar
  • How the tactical approach is different for debates and conversations
  • Jim’s advice for Christians who are interested in learning apologetics
  • How Christian apologist need to make sure they remain humble and open-minded
  • How your audience determines how much you need to know from study

Jim’s reason for becoming an atheist, (his mother was excluded from the Catholic church after her divorce), is one I have heard before. I like the way he eventually came back to Christianity. No big emotional crisis, just taking a sober second look at the evidence by himself, and talking with his Christian friends. I’m impressed with the way he has such a productive ministry, as well.

How the discovery of the cosmic microwave background radiation falsified atheism

So a couple of quotes to show that.

So, there are several scientific discoveries that led scientists to accept the creation event, and one of the most interesting and famous is the discovery of the cosmic microwave background radiation.

Here’s the history of how that discovery happened, from the American Physical Society web site:

Bell Labs radio astronomers Arno Penzias and Robert Wilson were using a large horn antenna in 1964 and 1965 to map signals from the Milky Way, when they serendipitously discovered the CMB. As written in the citation, “This unexpected discovery, offering strong evidence that the universe began with the Big Bang, ushered in experimental cosmology.” Penzias and Wilson shared the Nobel Prize in Physics in 1978 in honor of their findings.

The CMB is “noise” leftover from the creation of the Universe. The microwave radiation is only 3 degrees above Absolute Zero or -270 degrees C,1 and is uniformly perceptible from all directions. Its presence demonstrates that that our universe began in an extremely hot and violent explosion, called the Big Bang, 13.7 billion years ago.

In 1960, Bell Labs built a 20-foot horn-shaped antenna in Holmdel, NJ to be used with an early satellite system called Echo. The intention was to collect and amplify radio signals to send them across long distances, but within a few years, another satellite was launched and Echo became obsolete.2

With the antenna no longer tied to commercial applications, it was now free for research. Penzias and Wilson jumped at the chance to use it to analyze radio signals from the spaces between galaxies.3 But when they began to employ it, they encountered a persistent “noise” of microwaves that came from every direction. If they were to conduct experiments with the antenna, they would have to find a way to remove the static.

Penzias and Wilson tested everything they could think of to rule out the source of the radiation racket. They knew it wasn’t radiation from the Milky Way or extraterrestrial radio sources. They pointed the antenna towards New York City to rule out “urban interference”, and did analysis to dismiss possible military testing from their list.4

Then they found droppings of pigeons nesting in the antenna. They cleaned out the mess and tried removing the birds and discouraging them from roosting, but they kept flying back. “To get rid of them, we finally found the most humane thing was to get a shot gun…and at very close range [we] just killed them instantly. It’s not something I’m happy about, but that seemed like the only way out of our dilemma,” said Penzias.5 “And so the pigeons left with a smaller bang, but the noise remained, coming from every direction.”6

At the same time, the two astronomers learned that Princeton University physicist Robert Dicke had predicted that if the Big Bang had occurred, there would be low level radiation found throughout the universe. Dicke was about to design an experiment to test this hypothesis when he was contacted by Penzias. Upon hearing of Penzias’ and Wilson’s discovery, Dicke turned to his laboratory colleagues and said “well boys, we’ve been scooped.”7

Although both groups published their results in Astrophysical Journal Letters, only Penzias and Wilson received the Nobel Prize for the discovery of the CMB.

The horn antenna was designated a National Historic Landmark in 1990. Its significance in fostering a new appreciation for the field of cosmology and a better understanding of our origins can be summed up by the following: “Scientists have labeled the discovery [of the CMB] the greatest scientific discovery of the 20th century.”8

It’s the greatest scientific discovery of the 20th century.

In the New York Times, Arno Penzias commented on his discovery – the greatest discovery of the 20th century – so:

The best data we have [concerning the Big Bang] are exactly what I would have predicted, had I nothing to go on but the five books of Moses, the Psalms, the bible as a whole.

Just one problem with the greatest scientific discovery of the 20th century: atheists don’t accept it. Why not?

Here’s a statement from the Secular Humanist Manifesto, which explains what atheists believe about the universe:

Religious humanists regard the universe as self-existing and not created.

For a couple of examples of how atheistic scientists respond to the evidence for a cosmic beginning, you can check out this post, where we get responses from cosmologist Lawrence Krauss, and physical chemist Peter Atkins.

You cannot have the creation of the universe be true AND a self-existing, eternal universe ALSO be true. Someone has to be wrong. Either the science is wrong, or the atheist manifesto is wrong. I know where I stand.

Positive arguments for Christian theism

Why Christian parents get nervous about evidence when discussing Christianity

Homeschooling mother Dr. Lydia McGrew explains why Bible-believing Christians are uneasy with the use of evidence on her blog What’s Wrong With The World. (H/T Eric Chabot)

Excerpt:

4) The idea that, if a young person gets deeply interested in Christian evidence, he will go out on the Internet (or at his public high school or secular college) seeking giants to slay and will get overwhelmed. Again, this worry has merit as a sociological matter. That can certainly happen.

That is why we should say loud and clear to Christians interested in this topic: Don’t do that! What do I mean? Just this: Being committed to investigating the evidence for Christianity does not mean that one has to find out every possible thing that anyone has ever said about or against Christianity and know the answer to it. That would be impossible because of the sheer bulk of (ultimately unpersuasive) objections which skeptics can bring up as though they were real problems.

In this context the words of George Horne, an 18th century bishop, from his Letters on Infidelity, are wise and helpful. (Emphasis added.)

In the thirty sections of their pamphlet, they have produced a list of difficulties to be met with in reading the Old and New Testament. Had I been aware of their design, I could have enriched the collection with many more, at least as good, if not a little better. But they have compiled, I dare say, what they deemed the best, and, in their own opinion, presented us with the essence of infidelity in a thumb-phial, the very fumes of which, on drawing the cork, are to strike the bench of bishops dead at once. Let not the unlearned Christian be alarmed, “as though some strange thing had happened to him,” and modern philosophy had discovered arguments to demolish religion, never heard of before. The old ornaments of deism have been “broken off” upon this occasion, “and cast into the fire, and there came out this calf.” These same difficulties have been again and again urged and discussed in public; again and again weighed and considered by learned and sensible men, of the laity as well as the clergy, who have by no means been induced by them to renounce their faith.

[snip]

Many and painful are the researches sometimes necessary to be made, for settling points of that kind. Pertness and ignorance may ask a question in three lines, which it will cost learning and ingenuity thirty pages to answer. When this is done, the same question shall be triumphantly asked again the next year, as if nothing had ever been written upon the subject.

And a bit later:

5) The unspoken fear that Christianity cannot stand up to scrutiny and doesn’t really have good evidential support.

Here I do not blame the parents, but not because I share the unspoken fear. I do not blame them, because in most cases no one has ever taught them otherwise. How many pastors and priests have really taught apologetics to their congregations, or even offered such studies as an option? Too few. How many courses on sharing your faith have explicitly taught people not to get involved in responding to questions and objections but just to “share their experience” because “no one can argue with that”? Too many. It’s no wonder then that the congregation comes away with the sneaking suspicion that our Christian faith is no better grounded than Mormonism and that we, like they, must depend chiefly on the burning in the bosom.

And one can always push the blame further back. Perhaps the pastors weren’t taught Christian evidences at their seminaries.

In fact, I would not be surprised if all too many theologians who give high-falutin’ rationalizations for being anti-evidentialist are actually making a virtue out of what they deem to be a necessity. Since they don’t think Christian faith is founded on fact, they might as well make up some profound-sounding theological theory that tells us that it shouldn’t be.

When Nathanael asks Philip, “Can any good thing come out of Nazareth?” Philip simply says, “Come and see.” (John 1:46) And he brings him to Jesus. If you as a parent or mentor to the young are opposed to the study of Christian evidences partly because deep down you suspect that they aren’t very good, I can only say to you as well, “Come and see.”

I blogged about this tendency of church leaders to make a virtue out of laziness and ignorance before.

Here’s a snip:

Suppose a pastor or campus group leader wants to avoid having to learn physics and cosmology, or the minimum facts case for the resurrection, or how to respond to apparently gratuitous suffering, or the problem of religious pluralism. Suppose he thinks that Christianity, if it is about anything, is about his feeling happy and comfortable with a minimum of effort and work. So, he diligently avoids reading apologetics, because learning evidence is hard work. He avoids watching debates on God’s existence and the resurrection, because this is hard work. He avoids conversations with people who do study these things, and implies that there is something wrong with them for studying these things. He endeavors to conceal his laziness and ignorance and cowardice from his flock with much pious God-talk and fervent praise-hymn-singing.

Eventually, some member of his church asks him to go for lunch with an actual non-Christian family member. The pastor agrees and when he meets the unbelieving family member, he has nothing at all to say about typical challenges that unbelievers face. He has no knowledge of evolution, the problem of evil, the hiddenness of God, or the hallucination theory. He has never read a single atheist, and never read a single piece of evidence to refute them from Christian scholars. He lacks humility, refusing to admit that other Christian scholars may know more than he does because they have studied other areas. Needless to say, he fails to defend God’s reputation to the non-Christian. What will he say to the members of his flock about his failure? How will he justify his obstinate refusal to do what everyone else in the Bible does when confronting non-believers?

Well, consider this review of a recent book that defends the Gospels and the historicity of the resurrection by one such fideist pastor.

He writes:

There are, however, two significant shortcomings to the book.

First, Cold-Case Christianity places far too much emphasis on the role of extrabiblical sources. No doubt there is a legitimate role for biblical archaeology and extrabiblical writing from antiquity. Christianity is, after all, a faith firmly rooted in human history. But there is a grave danger when truth is suspended because of an apparent lack of corroboration from extrabiblical sources. And Wallace, I’m afraid, wanders too close to this dark side of apologetics.

All of chapter 12, for instance, is devoted to proving the Gospels have external corroborative evidence—“evidence that are independent of the Gospel documents yet verify the claims of the text” (183). Wallace then addresses the historicity of the pool of Bethesda and makes another worrying statement: “For many years, there was no evidence for such a place outside of John’s Gospel. Because Christianity makes historical claims, archaeology ought to be a tool we can use to see if these claims are, in fact, true” (201-202, emphasis added).

In other words, Wallace seems to suggest we cannot affirm the truth of the Gospel accounts without the stamp of approval from archaeology and other extrabiblical sources. Such reasoning is dangerous, not least because it cannot affirm the inerrancy of the Bible. But also, it places the final court of appeal in the realm of extrabiblical sources rather than of God’s all-sufficient, all-powerful Word.

That is a textbook definition of fideism – that belief is somehow more pious and praiseworthy the less evidence we have. And the best way to have less evidence is to study nothing at all, but to just make a leap-of-faith in the dark. Of course, a leap-of-faith can land you anywhere – Islam, Mormonism. Presumably this pastor is like the Mormons who eschew all evidence and prefer to detect the truth of Mormonism by “the burning of the bosom” which happens when people read the all-sufficient, all-powerful Book of Mormon. His view of faith is identical to theirs, and 180 degrees opposed to the Bible. He has made his leap-of-faith, and that leap-of-faith is not accountable to arguments and evidence. His faith is private and personal, based on his own feelings. He considers it blasphemous to have to demonstrate what he believes to those who disagree with him. Where is this in the Bible? It’s nowhere. But it is everywhere in anti-intellectual Christian circles.

[…]I think that Christians are much better off following the example of authentic Christian pastors like R.C. Sproul, who, in a conference on evangelism, invited Dr. Stephen C. Meyer to present multiple lines of evidence from mainstream science to establish the existence of God. The only reason not to take this approach is laziness, which leads to ignorance, which leads to cowardice. And failure. It is pastors like Pastor Bungle above who are responsible for the great falling away from Christianity that we are seeing when we look at young people. Pastors who pride themselves in refusing to connecting the Bible to the real world, with evidence and with policy analysis, are causing young people to abandon the faith.

I think that many people who reject Christianity can point to a general impression that they got from Pastor Bungle and his ilk that faith is somehow different from other areas of knowledge and that it was morally praise worthy to insulate faith from critical thinking and evidence. Pastor Bungle could never justify his view by using the Bible, but a lot of church leaders have that view regardless of whether it’s Biblical or not.

The really troubling thing that I see again and again in the church is when pastors base all of their opposition to behaviors like abortion and gay marriage on Christianity. This effectively makes it impossible to do anything about these issues in the public square, because Christians are then taught to have nothing persuasive to say on these issues to non-Christians. It’s like pastors are more interested in striking a pious pose with their congregations instead of studying secular arguments and evidence so they can equip Christians to actually solve the problem.
