How the discovery of the cosmic microwave background radiation falsified atheism

Christianity 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 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

Four reasons to think that atheism is inconsistent with scientific progress

Christianity and the progress of science
Christianity and the progress of science

When people ask me whether the progress of science is more compatible with theism or atheism, I offer the following four basic pieces of scientific evidence that are more compatible with theism than atheism:

  1. the kalam argument from the origin of the universe
  2. the cosmic fine-tuning (habitability) argument
  3. the biological information in the first replicator (origin of life)
  4. the sudden origin of all of the different body plans in the fossil record (Cambrian explosion)

And I point to specific examples of recent discoveries that confirm those four arguments. Here are just a few of them:

  1. An explanation of 3 of the 6 experimental evidences for the Big Bang cosmology (from Physics Forums)
  2. Examples of cosmic fine-tuning to allow the existence of conscious, embodied life (From the New Scientist)
  3. Evidence that functional protein sequences are beyond the reach of chance, (from Doug Axe’s JMB article)
  4. Evidence showing that Ediacaran fauna are not precursors to the Cambrian fossils, (from the journal Nature)

Atheists will typically reply to the recent scientific discoveries that overturned their speculations like this:

  1. Maybe the Big Bang cosmology will be overturned by the Big Crunch/Bounce so that the universe is eternal and has no cause
  2. Maybe there is a multiverse: an infinite number of unobservable, untestable universes which makes our finely-tuned one more probable
  3. Maybe the origin of life could be the result of chance and natural processes
  4. Maybe we will find a seamless chain of fossils that explain how the Cambrian explosion occurred slowly, over a long period time

Ever heard any of these responses?

Below I list some resources to help you to respond to the four responses of atheists to the experimental data.

1) The Big Crunch/Bounce has been disproved theoretically and experimentally.

Theoretically:

The impossibility of a bouncing universe

ALAN H. GUTH* & MARC SHER†

*Center for Theoretical Physics, Laboratory for Nuclear Science and Department of Physics, Massachusetts Institute of Technology, Cambridge, Massachusetts 02139, USA

†Department of Physics, University of California, Irvine, California 92717, USA

Petrosian1 has recently discussed the possibility that the restoration of symmetry at grand unification in a closed contracting Robertson–Walker universe could slow down and halt the contraction, causing the universe to bounce. He then went on to discuss the possibility that our universe has undergone a series of such bounces. We disagree with this analysis. One of us (M.S.) has already shown2 that if a contracting universe is dominated by radiation, then a bounce is impossible. We will show here two further results: (1) entropy considerations imply that the quantity S (defined in ref. 1 and below), which must decrease by ~1075 to allow the present Universe to bounce, can in fact decrease by no more than a factor of ~2; (2) if the true vacuum state has zero energy density, then a universe which is contracting in its low temperature phase can never complete a phase transition soon enough to cause a bounce.

Experimentally:

The universe is not only expanding, but that expansion appears to be speeding up. And as if that discovery alone weren’t strange enough, it implies that most of the energy in the cosmos is contained in empty space — a concept that Albert Einstein considered but discarded as his “biggest blunder.” The new findings have been recognized as 1998’s top scientific breakthrough by Science magazine.

[…]The flood of findings about the universe’s expansion rate is the result of about 10 years of study, said Saul Perlmutter, team leader of the Supernova Cosmology Project at Lawrence Berkeley National Laboratory.

Perlmutter and others found such a yardstick in a particular kind of exploding star known as a Type 1A supernova. Over the course of several years, the astronomers developed a model to predict how bright such a supernova would appear at any given distance. Astronomers recorded dozens of Type 1A supernovae and anxiously matched them up with redshifts to find out how much the universe’s expansion was slowing down.

To their surprise, the redshift readings indicated that the expansion rate for distant supernovae was lower than the expansion rate for closer supernovae, Perlmutter said. On the largest scale imaginable, the universe’s galaxies appear to be flying away from each other faster and faster as time goes on.

“What we have found is that there is a ‘dark force’ that permeates the universe and that has overcome the force of gravity,” said Nicholas Suntzeff of the Cerro Tololo Inter-American Observatory, who is the co-founder of another group called the High-z Supernova Search Team. “This result is so strange and unexpected that it perhaps is only believable because two independent international groups have found the same effect in their data.”

There has only been one creation of the universe, and the universe will never reverse its expansion, so that it could oscillate eternally. That view is popular, perhaps in part because many people watched videos of Carl Sagan speculating about it in public school classrooms, but all it was was idle naturalistic speculation, (Sagan was a naturalist, and held out hope that science would vindicate naturalism), and has been contradicted by good experimental science. You should be familiar with the 3 evidences for the Big Bang (redshift, light element abundances (helium/hydrogen) and the cosmic microwave background radiation. There are others, (radioactive element abundances, second law of thermodynamics, stellar lifecycle), but those are the big three. Point out how the experimental evidence for the Big Bang has piled up, making the problem even worse for the eternal-universe naturalists.

2) The multiverse has not been tested experimentally, it’s pure speculation.

Speculation:

Multiverse thinking or the belief in the existence of parallel universes is more philosophy or science fiction than science. ”Cosmology must seem odd to scientists in other fields”.

George Ellis, a well-known mathematician and cosmologist, who for instance has written a book with Stephen Hawking, is sceptical of the idea that our universe is just another universe among many others.

A few weeks ago, Ellis, professor emeritus of applied mathematics at the University of Cape Town, reviewed Brian Greene’s book The Hidden Reality: Parallel Universes and the Deep Laws of the Cosmos (Knopf/Allen Lane, 2011) in the journal Nature. He is not at all convinced that the multiverse hypothesis is credible: ”Greene is not presenting aspects of a known reality; he is telling of unproven theoretical possibilities.”

According to professor Ellis, there is no evidence of multiverses, they cannot be tested and they are not science.

Ellis is not the only multiverse sceptic in this universe. A few months ago, science writer John Horgan wrote a column in Scientific American, expressing his doubt in multiverses.

When you get into a debate, you must never ever let the other side get away with asserting something they have no evidence for. Call them on it – point out that they have no evidence, and then hammer them with evidence for your point. Pile up cases of fine-tuning on top of each other and continuously point out that they have no experimental evidence for their speculations. Point out that more evidence we get, the more cases of fine-tuning we find, and the tougher the problem gets for naturalists. There is no evidence for a multiverse, but there is evidence for fine-tuning. TONS OF IT.

3) Naturalistic theories for the origin of life have two problems: can’t make the amino acids in an oxydized atmosphere and can’t make protein and DNA sequences by chance in the time available.

[…]These results suggest that outgassing of Earth’s interior later than ~200?Myr into the history of Solar System formation would not have resulted in a reducing atmosphere.

Estimating the prevalence of protein sequences adopting functional enzyme folds.

Proteins employ a wide variety of folds to perform their biological functions. How are these folds first acquired? An important step toward answering this is to obtain an estimate of the overall prevalence of sequences adopting functional folds.

[…]Starting with a weakly functional sequence carrying this signature, clusters of ten side-chains within the fold are replaced randomly, within the boundaries of the signature, and tested for function. The prevalence of low-level function in four such experiments indicates that roughly one in 10(64) signature-consistent sequences forms a working domain. Combined with the estimated prevalence of plausible hydropathic patterns (for any fold) and of relevant folds for particular functions, this implies the overall prevalence of sequences performing a specific function by any domain-sized fold may be as low as 1 in 10(77), adding to the body of evidence that functional folds require highly extraordinary sequences.

So atheists are in double jeopardy here. They don’t have a way to build the Scrabble letters needed for life, and they don’t have a way to form the Scrabble letters into meaningful words and sentences. Point out that the more research we do, the tougher the problem gets to solve for naturalists, and the more it looks like an effect of intelligence. Write out the calculations for them.

4) The best candidate to explain the sudden origin of the Cambrian era fossils was the Ediacaran fauna, but those are now recognized as not being precursors to the Cambrian fossils.

Science Daily reports on a paper from the peer-reviewed journal Science:

Evidence of the single-celled ancestors of animals, dating from the interval in Earth’s history just before multicellular animals appeared, has been discovered in 570 million-year-old rocks from South China by researchers from the University of Bristol, the Swedish Museum of Natural History, the Paul Scherrer Institut and the Chinese Academy of Geological Sciences.

[…]This X-ray microscopy revealed that the fossils had features that multicellular embryos do not, and this led the researchers to the conclusion that the fossils were neither animals nor embryos but rather the reproductive spore bodies of single-celled ancestors of animals.

Professor Philip Donoghue said: “We were very surprised by our results — we’ve been convinced for so long that these fossils represented the embryos of the earliest animals — much of what has been written about the fossils for the last ten years is flat wrong. Our colleagues are not going to like the result.”

Professor Stefan Bengtson said: “These fossils force us to rethink our ideas of how animals learned to make large bodies out of cells.”

The trend is that there is no evolutionary explanation for the body plans that emerged in the Cambrian era. If you want to make the claim that “evolution did it”, then you have to produce the data today. Not speculations about the future. The data we have today says no to naturalism. The only way to affirm naturalistic explanations for the evidence we have is by faith. But rational people know that we need to minimize our leaps of faith, and go with the simplest and most reasonable explanation – an intelligence is the best explanation responsible for rapid generation of biological information.

Conclusion

I do think it’s important for Christians to focus more on scientific apologetics and to focus their academic careers in scientific fields. So often I look at Christian blogs, and I see way too much G. K. Chesterton, Francis Chan A. W. Tozer, and other untestable, ineffective jibber-jabber. We need to bring the hard science, and stop making excuses about not being able to understand it because it’s too hard. It’s not too hard. Everyone can understand Lee Strobel’s “The Case for a Creator“. That’s more than enough for the average Christian on science apologetics. We all have to do our best to learn what works. You don’t want to be anti-science and pro-speculation like atheists are. I recommend reading Uncommon Descent and Evolution News every day for a start.

Is Christianity false or is it just mean and judgmental?

Have you noticed lately that there is a decided lack of atheists who argue against Christianity on factual grounds? Instead of constructing arguments against Christian theism, what I am seeing more and more of is that people try to say that Christianity makes some group feel bad, and therefore Christianity is not worthy of pursuit and engagement.

Here’s how it works. You have a person who has some sinful habit or other that they don’t want to give up, and they notice that people are judging them and saying that what they are doing is wrong. And they feel bad. And they decide to attack Christianity to make the Christians stop judging them. So how do they do it? Do they argue that the concept of God is logically incoherent? No… Do they argue that some instances of evil and suffering are gratuitous? No… Do they argue that the universe is eternal so that it had no Creator? No…

What do they do?

What they do is pick on some statement by a conservative Christian that makes them feel bad, and then claim that they are victims of meanness. And apparently, making someone feel bad is some sort of disproof of Christian theism. Why is that? It’s because we have decided as a culture that the purpose of religion is to make people feel good about themselves and to be “nice” to other people. And by “nice”, we mean not making other people feel bad about the sinfulness of their behavior. So people are making Christianity irrelevant just by assuming that the purpose of life is happiness, and that any religion that makes people unhappy can be dismissed.

Before, people thought about Christianity as something that you investigated, and that was either true or false. People understood that Christianity made claims about the external world that were either true or false. For example, Christianity claims that the universe had a beginning in the finite past. And the people who disagreed with Christianity would try to produce arguments and evidence that the universe was eternal, as with the steady-state theory or the oscillating model of the universe. And people were willing to change their behavior to match what was true, even when it made them feel less happy. But not any more.

Religion today is not about truth

I think somehow, as a society, we have internalized the following beliefs:

  • God wants me to have happy feelings
  • the purpose of religion is to give me happy feelings
  • God’s moral will for me is that I be “nice” to others
  • being nice to others means accepting whatever they want to do as “good”
  • accepting whatever anyone does makes them like me
  • when people like me, I feel happy, which is what God wants
  • there is no need for me to study God’s existence
  • God exists when I want to be comforted, and doesn’t exist when I want to sin
  • there is no need for me to study God’s character
  • God’s character is pretty much like my character, whatever I want is fine with God
  • there are no moral rules or obligations from God that apply to me
  • religions are all the same, I choose the one that makes me feel happy

So you can see that someone who believes things like this can claim to be a Christian, but would actually attack real Christians who hold to the old view of exclusive factual claims and moral judgments. The real Christians are people who have studied these questions, who know that God exists, and what he is like, and accept the Bible’s moral teachings as authoritative. So you could have a famous pastor who defends the Bible’s prohibition on sex before marriage, and have someone feel bad about being judged, and then a bunch of these “the purpose of life is happiness” people will appear and chastise that pastor for making people feel bad. And many of them will claim to be Christians, and attend church, too.

Now notice that this mob of happy-feelings people are not going argue against the pastor using the Bible, because the Bible is pretty clearly against fornication. What they’ll do instead is they’ll pick out some piece of the Bible that seems unfair, like the slaughter of some group of child-sacrificing pagans, and they’ll rail against that Bible passage in order to discredit the Bible’s authority on moral questions. And then the good conservative pastor is made to feel bad because he has broken those unwritten laws – he made someone feel bad using this evil book.

No factual claims about God’s existence were made. No historical arguments were made. No evidence was presented. The mere fact that the Bible is mean to talk about killing the poor Canaanites is used to prove that the Bible has no moral authority at all, on any issue. “It’s mean” entails that it’s false. And you can have people who read the Bible for devotions, who sing in church, and who lead worship, who think that the Bible is false because it’s mean, and it’s mean because it can be used to judge people and make them feel bad.

An example

Now consider single motherhood, as in this case.

Excerpt:

She tells her children to do as she says and not as she does.

But the words of mother of 14 Joanne Watson – who receives more than £2,000 a month in state handouts – have fallen on deaf ears.

Her 15-year-old daughter Mariah is pregnant, the father has ‘left the scene’, and the youngster is about to start living off benefits.

Mrs Watson, 40, is raising her giant brood alone after parting from her husband John, 46, three years ago, and breaking up with subsequent partner Craig le Sauvage, 35, last year.

Despite this, she has still managed to squirrel away enough cash for a £1,600 breast enhancement and a sunbed. She claims she has always encouraged her daughters to use contraception – but, inevitably, it seems they would rather follow the family tradition.

Mariah’s pregnancy comes after Mrs Watson’s oldest daughter Natasha, 22, got pregnant with her son Branford, now six, when she was 16. Her second eldest daughter Shanice, 19, also got pregnant at 16 with her 22-month-old son Marley.

Mariah says she has no concerns about becoming a teenage mother, as it seems the most natural thing in the world. Initially, she and her child will be supported by the taxpayer.

She is expected to move into a housing complex for single mothers and will receive supplementary benefit and child allowance for her baby.

The youngster, who is due to have a boy, said: ‘I’m not nervous. I’ve been around babies my whole life so I know what to expect and that I can handle it. The father isn’t involved and I don’t want him to be either. I’m really excited and think I will be a great mum.’

Now there are two responses to this from people who profess to be Christians. The first response, my response, is to make a general argument against having sex before marriage, using the latest statistics to show the harm that fatherlessness causes to children, and more evidence besides. My response is not to pick on any one person, but to set moral boundaries, to make moral judgments against the selfishness of parents, and to not celebrate and subsidize anything that will harm innocent children. I don’t want to make anyone person feel bad, I just want to say what the evidence is. However, even a general argument using evidence does make some people feel bad, so I am judged as “mean” for giving my opinion and backing it up with evidence.

But there is another response. This response comes from someone who professes to be a Christian, but they are actually a “God wants me to be happy and to be nice to people so they will like me and then we’ll all be happy” person. They would never dream of judging anyone for anything they do. And they are very angry with me for getting my moral rules out of that horrible Bible, and for using facts and evidence to make people feel bad. They believe in compassion, which is the idea that says that the moral boundaries of the Bible are false, and that we have to celebrate and subsidize any and every variation on the traditional family, regardless of the harm caused, so that the selfish adults don’t feel bad about their destructive choices.

And what do we make of a person who feels that saying “it’s wrong” is mean, because it makes a guilty person feel bad? Well, here is the truth. A person who argues against the Bible based on the happy-feelings model is no friend of God, and no friend of the victims of selfish actions. They may think that they are being a good person by affirming people who make bad decisions, but really it just encourages people to get into trouble.
