Why do atheists believe in unobservable entities and weird things?

3 Comments

Consider this summary of an article in Nature written by George Ellis, a famous cosmologist based in Cape Town, South Africa.

Excerpt:

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.

Multiverse thinking is basically an atheistic attempt to solve some huge problems with the big bang and explain why the universe could have been formed without a design or a Designer.

Now how do the theorteical physicists respond to this?

Here’s an article from Scientific American responding to Ellis. (H/T Uncommon Descent)

Excerpt:

This picture of the universe, or multiverse, as it is called, explains the long-standing mystery of why the constants of nature appear to be fine-tuned for the emergence of life. The reason is that intelligent observers exist only in those rare bubbles in which, by pure chance, the constants happen to be just right for life to evolve. The rest of the multiverse remains barren, but no one is there to complain about that.

Some of my physicist colleagues find the multiverse theory alarming. Any theory in physics stands or falls depending on whether its predictions agree with the data. But how can we verify the existence of other bubble universes? Paul Steinhardt and George Ellis have argued, for example, that the multiverse theory is unscientific, because it cannot be tested, even in principle.

[…]Our universe appears surprisingly fine-tuned for life in the sense that if you tweaked many of our constants of nature by just a tiny amount, life as we know it would be impossible. Why? If there’s a Level II multiverse where these “constants” take all possible values, it’s not surprising that we find ourselves in one of the rare universes that are inhabitable, just like it’s not surprising that we find ourselves living on Earth rather than Mercury or Neptune.

[…]George argues that if we take seriously that anything that could happen does happen, we’re led down a slippery slope toward even larger multiverses, like the Level IV one. Since this is my favorite multiverse level, and I’m one of the very few proponents of it, this is a slope that I’m happy to slide down!

Is the multiverse theory a good response to the fine-tuning argument? It seems to me that the fine-tuning rests on solid experimental evidence, while the multiverse rests on what-if speculations about unobservable entities.

Bulgarian government scientist claims aliens oppose global warming

6 Comments

Story from the UK Register. (H/T The Drew Blog)

Excerpt:

A boffin [researcher] at the Bulgarian national Space Research Institute has stated that not only are aliens living among us, but that they object strongly to “immoral behaviour” by humanity – such as causing global warming. “Unnatural” acts such as use of cosmetics and “artificial insemination” are also frowned upon by the extraterrestrial visitors.

Luchezar Filipov, deputy head of the space institute at the government’s Bulgarian Academy of Science, made these startling assertions to Bulgarian media earlier this week.

The Sofia Echo, referencing other local media, quotes the eminent space brainbox as stating that “they [aliens] are here right now, among us” and that the extraterrestrials are “conducting surveillance” and – chillingly – “research” on humanity.

“They are currently all around us, and are watching us all the time. They are not hostile towards us; rather, they want to help us but we have not grown enough in order to establish direct contact with them,” said the Bulgarian boffin, according to Sofia news agency novinite.com.

Reportedly Filipov and unnamed colleagues have elicited this information by decrypting messages hidden within crop circles. The crop-circle “pictograms” were said to have been a response to questions posed by the Academy scientists.

[…]”The aliens are very critical of our immoral behaviour and our destruction of the environment,” says Filipov, according to the Echo. “They say that global warming is attributed mainly to infrastructural engineering.”

This reminds me of that movie “The Man From Tomorrow” or whatever where the alien spaceman tells the ignorant Americans how to live. This politicization of science really needs to stop.

How I respond to atheists who speculate about unobservable entities

2 Comments

I noticed a new comment to my article explaining how to argue for God from the fine-tuning of the universe.

The commenter wrote this:

Hey, atheist here. Just astounded by your characterisation of the atheist’s response. I’ve never heard any atheist use the argument that humans caused the fine tuning. It doesn’t make sense because humans would still have to exist in some now corrupted timeline where the universe wasn’t fine-tuned.

I have a whole post on my blog dedicated to this topic but I’ll summarise my main arguments.

[SNIP! See below for his 8 points]

Maybe you can integrate these arguments into your post and address them, instead of a straw man?

This is a pretty good comment, with only a little acceptable snark at the end. I hate it went people write loads and loads of stuff without citing any evidence.

And I wrote this back:

Thanks for your comment. You’ll note that in my piece I cited numerous scientific facts and produced an argument that was logically valid. Now let’s take a look at what you wrote.

And here’s how I replied to his 8 points.

“1. Possibility of a multiverse.”

1) This is a speculation with no scientific evidence. Notice how I appeal to an experimental particle physicist for my conclusion.

“2. Possibility of an oscillating universe”

2) This has been disproved theoretically and observationally. Notice how I cite research papers that do not merely speculate, but are based on observations.

“3. The Vast (to use Dennett’s terminology) majority of the universe does not contain life, so to claim that life is its purpose is merely superimposing your own subjective judgement onto it.

3) This is speculation about God’s motives. You are not in a position to dictate to God how he would have accomplished his goals. If you would like to listen to William Lane Craig speak on these scientific arguments, and listen to Dennett’s LAME response, click here.

“4. Related to 3. Clearly the universe is fine-tuned to make hydrogen, since that is the most abundant substance in the universe. Life seems to be fairly far down in the priorities of the universe. Of course I’m (half) joking, but there is no reason why one natural phenomenon needs a fine tuner any more than any other.”

4) This is speculation about God’s motives. You can feel free to joke about the evidence for and against God. I don’t joke about these issues – I prefer to cite evidence.

“5. The argument flauts its own premises by posing the existence of a creator which doesn’t need a fine-tuned universe. So either the premise is wrong, or we have an infinite regress of fine-tuners.”

5) Fine-tuning is an example of intelligent design such that a selection from a field of possibilities corresponds to an independently specified pattern. I.e. – the subset of functional proteins compared to the set of possible sequences of amino acids. God is not composed of parts so is not fine-tuned.

“6. We have no idea if these constants are even capable of changing. To state that they have been fine tuned without this information is nothing more than speculation.”

6) This is more speculation. Don’t make arguments based on what “we” don’t know. I make arguments based on what we do know. You do the same.

“7. It could be that the state of the universe is unlikely, but not as unlikely as the existence of a fine-tuner. In this case it would just be a big coincidence.”

7) “It could be…” It could be that monkeys will fly out of my butt. Stop speculating about things we cannot know. Let’s see your argument, and the peer-reviewed data to back it up. This is not a game.

“8. Even if the fine-tuning argument were valid, it says nothing about the type of creator that exists, so to go from this deist creator to the Christian God is a huge leap.”

8) The argument is not meant to prove the Christian God. The argument, taken together with a bunch of other scientific arguments, is meant to prove a Creator and Designer of the universe. To prove Christian theism, you make a case for the resurrection and then debate it in public in the university. And then you respond to philosophical objections, such as evil, suffering and the hiddenness of God.

I thought it was a useful example of how to ask people for arguments and evidence, and not take a speculation for an argument.

I find that atheists speculate a lot about unobservable entities in order to escape from good scientific arguments. They speculate about hyper-universes to explain the big bang. They speculate about a multiverse to explain the fine-tuning. They speculate about aliens seeding Earth with life to explain the origin of life. They speculate about as-yet-undiscovered precursor fossils to explain the Cambrian explosion. They speculate about as-yet-undiscovered developmental pathways that use co-option to get around irreducible complexity. And on, and on, and on.

And that suggests to me a question. What sense does it make to build an entire worldview on speculations about things you cannot observe? Or is atheism not about truth, then, but instead about thinking that you are better than other people and throwing off the demands of morality? If the truth is that God exists and that Jesus rose bodily from the dead, then why try to dance around it using speculations? What possible benefit could there be, ultimately, to having blind faith in a religion just to pursue pleasure?
