A Debate With A Vague God Enthusiast

Haven’t blogged for a bit, so I’m storming back with a long one. In addition to that, I have a larger than average blog post for your delectation.

My girlfriend and her friend ended up talking about God, and my name got mentioned – presumably because I’m just that awesome. My GF, as someone who’s pretty much had her faiths eroded by my niggling arguments (“Shall we get some wine? Also, why would an all-powerful God allow evil to occur?”) wanted her friend to talk to me on the subject. She prepared a short argument and I emailed her my response.

Something I wasn’t aware of until after I’d emailed her was that she is, apparently, very stubborn and will never let go of her beliefs. Which renders debate more or less meaningless, but hey – who knows?

 

“What is sense? Why can’t open minded thoughts help you accept a possibility of a greater power/energy source named as god?”

I think my GF gave you the wrong impression of my perspective on this issue. I accept the POSSIBILITY of God, or a higher power, simply because it would be scientifically hypocritical to state with certainty that it could NOT exist. Until every iota of the universe has been catalogued, which is almost certainly something we will never do, we cannot posture with certainty on such matters. To state something CANNOT exist is a faith-based position, albeit anthetical to faith IN a God, and as such is a position not often adopted by intellectuals.

So, I can accept the possibility. But with a complete lack of any positive proof, there is no point considering it further. An inability to disprove something is not adequate proof FOR it, otherwise you would have to give equal credence to absolutely every unfalsifiable hypothesis anyone ever makes. Along with your concept of God, you’d have to grant the equal chance of everyone else’s concept of God, along with all supernatural claims. This is without even going into the logical paradoxii that arguments for God tend to invoke, which I’ll go into a bit later..

“Why can’t there be a god?”

I’d need to know more detail about your concept of God to answer this. However, in general, God creates more questions than it answers. Simply using God as a catch-all answer to the mysteries of the universe is unrealistic, because you then have to explain God. You end up with paradoxii of omnipotence, problems of free will, problems of omnicognisance. So tell me more about your perception of God – is it conscious? Insensate? Does it have a specific purpose? What powers does it possess? Is it immortal/eternal/invincible? Is it limited in any sense?

Until I have more detail, though, the simple answer is there COULD be a God – but it’s so vastly unlikely, so internally inconsistent and contradictory by most human accounts, that there’s no point in pursuing it. As we on the internet say, pictures or it didn’t happen. The onus of proof is ALWAYS on the other side to substantiate God – NOT on me to disprove.

“By opening your mind and thoughts you accept possibilities, by accepting possibilities you become more knowledgeable, and by being more knowledgeable you are naturally more intelligent.”

Accepting possibilities is fine. It’s what drives scientific endeavour and progress. But you don’t actually become more knowledgeable until you have proved these possibilities as something workable. There’s some famous quote, I think from Richard Dawkins, which is more or less “Be open-minded, but not so open that your brain falls out.” Wondering how things work and having a spirit of enquiry keeps discovery constant; however, that is no reason to hang on to the impossible or the unworkable. The historical precedent is that poorly understood natural phenomena attributed to the supernatural (for example, the various cultural pantheons to whom natural forces and processes were attributed via individual deities, as opposed to monotheism where a single entity controls everything – this seems to be what you’re postulating) eventually become explained by scientific means. The age of simply hypothesising something which sounds about right is long gone. The age of empiricism demands proof, repeatable observation, before a possibility becomes workable. Otherwise the whole thing simply collapses in disarray under the weight of countless “possibilities” which can only be accepted because they cannot be completely disproved.

That is the nature of science, of course. It operates on inductive reasoning, on extending an assumption from a necessarily limited sample group. However, deductive reasoning – which begins from an axiomatic statement and is thus considered to be more reliable than inductive logic – is never grounded in the real world. Only logical and mathematical constructs can be axiomatic. A famous deduction is “All are mortal. Socrates is a man. Therefore Socrates is mortal.” However, this deduction relies on inductive empiricism for its axiom. The only way of looking at the world and the universe is by the scientific method; only abstracts, like logic and maths (human constructions) produce axiomatically true results – and these results are definitionally divorced from the real world.

“Where did the first energy source come from?”

We’re working on it 🙂

We don’t know. The origins of the universe are pretty trippy to consider. However, given the aforementioned historical precedent of supernatural explanations being superceded, it’s reasonable to assume that we will eventually know – and not knowing NOW doesn’t mean we will NEVER know. Also, not knowing the origins of the universe is comparatively simple when compared to using God as an explanation and then trying to work out how God created itself, or all the other attendant problems with using God to explain anything.

“Do humans have any energy source beyond physics? Why? Why not?”

If human beings have an energy source beyond physics it’s pointless to even speculate as it necessarily wouldn’t be something we could even detect. If we could detect it, it would be an aspect of known physical laws and not metaphysical or supernatural in nature. So, no, humans do not have an energy source beyond physics because the question doesn’t have any actual meaning – you’re asking to verify something which definitionally, as soon as it is verified, STOPS being beyond physics.

“Bear in mind that without self-evidence there is none. With no evidence, you rely on belief. Therefore proof is belief. If belief is your source of proof why can’t you believe in god and use belief as proof.” (I nearly pooped myself when I read that argument.)

That’s a little too much of a logical leap though. Proof is NOT belief. Proof is proof. Belief implies some kind of dependence on the believer for continuation, and gravity doesn’t care if you believe in it or not. Scientists don’t rely on belief or faith, and neither do the things the scientific method discovers.
Your argument dictates that, if belief is a proof, EVERYTHING is real and possible. Jeremy, the unicorn inside Jupiter who controls gravity (but only in this solar system) is real because I have belief in him – and thus proof. And, of course, the concept of God that I believe in that forces all possible Gods to NOT exist (including yours) must be real, because I have belief.

Belief is not the source of proof for scientists, or for me. Repeatable, observable testing and evidence is proof. Proof that is consistent with all previously gathered research. Using belief as proof not only invites a great deal of confusion, it’s demonstrably untrue, and it indicates a lack of any REAL proof for claims. If your proof is belief, you are admitting that you have no concrete evidence on which to go on.

 

So now, we wait . . .

Radio debate “Evolution”: djarm67 vs Dr Steve Kumar

A couple of days ago, Mrs djarm67 was told that a local radio station was going to host a speaker who would confront the “New atheism” movement and evolution. I took the info on board and began listening to the station to get some more info, e.g. when and who. This proved to be a mildly irritating experience within itself as my musical tastes are stimulated far more easily by a combination of prog-rock and hybrids of grunge, psychedelia or various brands of metallic funk with at least a short term residence in the Phrygian mode. This exercise was made somewhat more pleasant with the lubrication of a blend of Hunter Valley Cabernet Merlot. Eventually, it was revealed that the event was to occur not just on the Sunday night but would utilise frequency modulation of the VHF electromagnetic spectrum. The proponent gracing the airwaves at that time to “confront” this new atheism and evolution would be Dr Steve Kumar.

Heard of him?

Neither had I.

So began the extension of my love affair with all things online. I began to investigate the “who” behind the scheduled event. Who is this Dr? A Dr of what? Where did he get his doctorate? Was it legitimate or Hovindesque?

I found many examples of duplicates of his bio (marketing brochure) which attested to an awesomeness clearly in excess of anything I could hope to muster. Finding out what he was a doctor of or where he got it proved difficult and I actually had to rely on his introduction on the radio programme itself to educate my ignorance that I would be dealing with a “Doctor of Philosophical Theology” if I chose to enter the field of battle.

Here is Dr Steve Kumar

Dr Steve Kumar

I did find a reference which indicated he had received his doctorate from the same “California diploma mill” as disgraced NZ MP Bernie Ogilvy (who I believe claimed to possess a law degree from an institute which did not even have a law programme). A brochure promoting the “Eleventh annual European summer study session of the International Academy of apologetics, evangelism and human rights” lists Dr Kumar as “Faculty and Advisory” alongside a conspicuous William A Demski. Post-interaction with Dr Kumar, I found another reference which indicated that the institute in question is the “California Graduate School Of Theology” (a worthy member of the Wikipedia “List of unaccredited institutions of higher learning”)

So here I was. An anonymous YouTuber with dreams of “League of Reason” blogging prowess about to confront some (apparently) world renowned Christian apologist who was a doctor no less. I had never been involved in a live radio debate previously. When responding to those on forums or my YouTube channel, I have the luxury of being able to research an answer prior to responding (a luxury not present in the heat of the battle which is talk back radio). I set up my tape recorder, turned on the radio and reached nervously for the phone. Here is the result.

This debate is split across two YouTube videos. Please watch both as I am a blatant video view whore. Oops, I mean I think you will enjoy them both. I’ve included accompanying images and video footage which I hope you will find humourous.

The Argument From Design Is Pretty Bad

You’ve probably come across this one a lot. Variations on the theme of “Everything is really super complex\the universe is obviously custom made for our please\life is designed, it couldn’t have happened by chance ERGO GOD” crop up all the time.

When you think about it, it’s pretty disgusting. It reveals a shallowness of intellect and reasoning that’s staggering.

The evolution of the eye is the most oft-quoted piece of “evidence” for intelligent design. “Look at this thing,” they’ll bluster, spit rolling down their chins. “Look at it! It’s really super complex! How could it possible have happened by chance? It’s perfect! Can you lend me a nickel?”

Ignoring the fact that the eye’s evolution has been pretty well covered by a number of people, the eye is NOT perfect. Not by any means. It is our most important sensory apparatus, far more so than hearing or smell, and yet this apparently God-patented design can be rendered inoperative by simply poking at it a bit too hard.

The eye manages to be one of the most important and most fragile parts of our body at the same time. Get a piece of grit in it and you’ve pretty much lost the rest of your day. Expose it to minimal pressure and it’s gone. A lot of people don’t even have eyes that work properly in the first place; I wear contacts to correct the flaw that God must have deliberately inflicted on me.

How could anyone look at the eye and think it could be designed? How hard would it have been for God to cover it in a thick protective layer instead of leaving it moist and vulnerable to the world? If people are going to appropriate natural evolution as proof for intelligent design, they MUST take into account all the flaws and room for improvement. Except they don’t, of course. The standard response is something like “Everything was perfect until SIN (even though God knew it was going to happen and could have stopped it and therefore we should be absolved of all responsibility but shut up SHUT UP don’t tell anyone) and then everything started to degrade.”

It’s pretty bad.

Worse still are the tactics used to support this “evidence”. Probably the most famous quote mine of all is the one that seems to have Darwin saying “I freely admit that the eye happening by itself seems impossible” (to paraphrase.) This quote is launched by IDists the world over. However, the full quote doesn’t end there; Darwin goes on to say “oh wait, I was trolling. It’s entirely possible in small steps. See how I talk in detail for a few pages.”

To quote mine in this way, the miner MUST have read it in context and then decided which bit best supported his cause. This tactic goes beyond cunning, sly and underhand – it enters the realm of reprehensible duplicity. It’s really not cricket. And yet this tactic attends creationist arguments constantly; misquotes from Einstein, Hawking and even Dawkins pepper the creationist world.

Sensible people can see this as simply more proof for the shaky foundations of intelligent design, but it’s still pretty annoying.

Why Europa Is Awesome

Here’s why, although most of you probably already knew.

It’s something that excited me ever since I first found out about it and began revolving it through my brains. Despite chances rising for life on Mars, Europa remains a more mysterious and potentially fruitful location. An icy Jovian moon, Europa is believed to possess a sub-surface ocean beneath a crust of ice, kept warm and fluid by tidal heat.

So . . . complete darkness, high pressure, possibly considerable heat, potential toxicity. It doesn’t sound altogether promising.

Except life fluorishes on Earth in environments at least as harsh and alien as those existing in the chilly reaches of space. Where? Oh god, where? Are we safe? Where do these barren tracts lie?

Mainly, in the sea. The deepest part of our ocean is nearly 11,000 metres, and life exists at the bottom of it. Life exists around deep sea vents, in extremes of pressure, heat and toxicity that would do credit to the kind of planet hitherto only seen in 70s adventure shows. This life has no need of light, favours heat and pressure with a jaunty smirk, and eats chemicals. In short, it’s just . . . different.

Why is this significant? Well, we no longer have to find soft, human-friendly worlds in order to hunt for extraterrestial life. If life can exist under nearly 7 miles of water, or not only survive but thrive on hot, chemical-rich environments, the vista of possibility is far wider. All we need is a place with chemicals and water and heat that’s had some time to stew, and even in our own solar system there’s more than a few possibilities: Mars, Europa, Titan, Enceladus, even Ceres.

Unless something unexpected happens, probes will reach Europa within my lifetime; although actually getting under the surface will be a bit tricksy.

NOTE: None of this is new information and I’m not trying to sound smart by going on about it.

Nanotechnology wins again!

Greeings from Denmark Leaguers! Just stopping by to post a bit of research that’s generating a buzz today. A team at the Swinburne University of Technology in Melbourne, Australia have developed a technique for squeezing a potential 10 terabytes (!) of storage out of a DVD without compromising the size of the disc. This involves adding two additional “dimensions” to the format, namely colour and polarisation. These aren’t spatial or time-like dimensions – there is thus far no concrete evidence that our universe has any more than 4 dimensions – but rather two properties that can be exploited using nanomaterials. Firstly, these next generation discs would be able to respond to multiple wavelengths of light, as opposed to current discs which are monochromatic. This adds a range of colour values that can be manipulated within the same physical space on the disc, thus adding another dimension. Polarisation of the materials on the disc allows another possible range of information in the same space by altering the angle of the surface materials. By using materials that can adopt a range of angles, it is possible to influence them by polarising the light in the laser (setting the orientation of the electric field). I for one completely support this fresh way of thinking (as opposed to more stale attempts to increase data density, such as Blu-Ray) and I’m pleased to see that Samsung are now on board with this project. Apparently, we’ll see them being made commercially available in 5-10 years. I haven’t had a chance to read the paper yet, published in this month’s edition of Nature, but if you have access to the Journal, you can read it here. If not, you can always read the abstract!

I also would just like to say welcome to our newest bloggers, JRChadwick and SchrodingersFinch!

Life Could Easily Have Survived Meteor Bombardment 3.9 Billion Years Ago

One of the more annoying battle cries of creationists, or indeed anyone who seeks to disprove the workability of the abiogenesis model, is “But 3.9 billion years ago all life would have been wiped out by an epic meteor bombardment NOT LEAVING ENOUGH TIME FOR US TO EVOLVE TO THE STATE WE ARE NOW THEREFORE GOD DID IT.”

Now, from my perspective a meteor bombardment would have had to be sustained and concentrated enough to vaporise the seas and turn the entire surface of the earth to molten slag before you could make an assertion like “All life would have died.” We’re not even talking life as we know it, just single or maybe multi-celled organisms – organisms which are numerous, resiliant and extremely quick to reproduce. If only one was left alive, life would have continued.

So it’s nice to see my untutored assumptions backed up by science. A study from the University of Colorado shows that life could easily have survived the bombardment, thus potentially increasing the age of life on earth by several hundreds of millions of years.

And if life can survive a meteor strike of such intensity, it could have survived it on other planets as well. I’m waiting with impatience for news of Mars.

New primate fossil found

I would like to introduce you all to Ida, a holotype of Darwinius masillae

At 47 million years old, it puts this amazingly detailed fossil at a time period just after the split between strepsirrhines (Lemurs and Lorises) and haplorhines (us, other apes and monkeys). The detail on this is absolutely extrordinary. They are even able to analyse the digestive tract. Ida was preserved in a maar lake deposit as a result of a volcanic explosion turning a lake into an Eocene version of the Texas Chainsaw Massacre (without the garden implements). Analysis of the teeth show this specimen to be a young juvenile animal.

If you feel inclined, trot on over to PLoS for the paper. There are also some great CT scans.

Ida being a bit negative

In the shadow of Atlantis

Atlantis transits the Sun (click for full size)

This truly spectacular image (click for full size) shows us the silhouette of STS-125 Space Shuttle Atlantis against the Sun. Taken for NASA by Thierry Legault on Tuesday, it captures Atlantis en route to its rendezvous with the Hubble Space Telescope (HST-SM4). Hubble is currently in the shuttle’s cargo bay, where the crew yesterday installed the Wide Field Camera 3 (successor to the Wide Field and Planetary Camera 2). On saturday, they will also install the Cosmic Origins Spectrograph and repair the Advanced Camera for Surveys. They are also making several other repairs, in what will be the final Hubble servicing mission before its orbit is terminated, probably around 2014. Atlantis is just under 40 metres long, and 350 miles high in this picture!

Anyway, I thought some of you might enjoy this beautiful image too.

Idealistic Musings On Space, The Universe, And What The Duck Has Planned For Us

Whatever the duck does have planned, I’m willing to bet it will be spectacularly unpleasant. Anyway.

It might be considered a disadvantage to talk about space considering I know virtually nothing about it. When I go on Wiki to discover new and crunchy space facts, I skip past all formulae or esoteric terminology; about the only numbers I can cope with are the ones describing size (15,000 miles? I must write that down). I am, in any practical sense regarding space, stupid. I gawp at the pretty photos and loll my tongue at the details of size, age and speed but when it comes to really understanding the underlying fabric I sort of zone out.

It’s tempting to defend my naivety by saying “Well, I see the world through the innocent eyes of a child, I don’t need any more’ but it’s not as if knowledge dulls your ability to feel wonder. We all need more, I’m just not fitted with a brain that can take it.

I’m pretty much a late arrival into the whole “space is fantastic’ thing, it was never something I considered much until recently. I made appreciative noises when confronted with facts like “OMG THREE EARTHS COULD FIT INTO JUPITER’S RED SPOT’ but never really made the connection between interesting facts and the true reality behind them.

Seasoned astrophys types like AndromedasWake, who is officially recognised as Knowing About Space, probably hide condescending smiles behind their hands when I go on like this. After all, they’ve known for years. But I’m like a child in a sweetshop and a stolen wallet, except the sweets are facts and the wallet is the interblagz. I could probably take this metaphor further.

I won’t.

The gist of this is . . . look up. Try to reconcile your limited perception of distance with the fact that we are tiny, just one planet going round a small star in a galaxy that is one of billions, hundreds of billions.

It’s tough. So start small. Let’s take the moon.

You can see the moon most nights, and it’s pretty. But even when it’s really very pretty indeed, it’s seldom remarked upon as anything more exciting than, say, scenery. People don’t look at the moon and think “Holy wowz, that’s a small planet. A small planet that’s so close I can make out incredible detail with my naked eye. With a telescope, I may as well be there.’ Why would you think that? It’s a more or less constant background to the night sky. But after the sun, it’s the clearest intrusion of the universe into our world. The nearest clearly visible extraterrestrial body, massively plunging through space even as you look at it. Just try to make a connection with it as a real object, as an entity in itself both separated and linked to us, far from reach but tantalisingly clear.

Now, let’s try something a little bigger. Find some dark glasses and look at the sun. (I am, of course, obliged by some feeble moral tendril to tell you that looking at the sun without adequate protection can result in damage to your eyes. Don’t do it.) If you widen your eyes and get used to the glare, you can see the disc pretty easily. Much like the moon, the sun is seldom really thought of. It’s just there. Except the sun is a bit more special than the moon. All those stars you can see at night? That’s what the sun is, except it’s close enough to be seen as a large, visible disc. It’s a star, and it’s right there. Go outside and look at it. Now! It’s unimaginably large, unimaginably far away, and we can see it. There are billions upon billions of these things in the universe. Even from 93 million miles, we can barely look at it without protection. Are you looking yet?

And then there’s the other planets, some of which can be seen with the naked eye. Real objects, as real as this planet but strange and different and untouched.

It’s hard to get out of the comfort zone and think about where we really are, how we are utterly insignificant even within our own solar system – let alone the monstrous size of the universe. Scale ceases to have any meaning at all. As soon as you even try to grasp where we actually are, that every point of light in the sky is a bewilderingly large star that exists, as real as our own or the ground you stand on, and the intervening space is almost completely empty tracts of vacuum (and, of course, the stars we can see with our eyes are but a fragmented slice of the entirety) . . . your mind sort of sheers away. It’s like having a thought just out of reach of your mind, but so much more. Just think of the gaps, of the reality of such cosmic beauty that we’ll never touch, that we can only look at from a distance more or less impossible to grasp. And think of the near-certainty that there is other life of some kind, somewhere – probably some many wheres – within the hundreds of billions of galaxies we’ve so far detected.

I know the barest crumb of all the knowledge available, and couldn’t begin to understand most of it. To everyone who’s already realised how ridiculously magnificent the universe is, ignore my burblings. To everyone who doesn’t really think about it, go outside and look up. Try just to grasp the night sky as an entire panorama of reality completely outside ourselves. All I know is . . . it’s amazing. I can’t tell you how to feel it, I can just say that it freaks me out in a manner both depressing and uplifting.

Watch this video. It may or may not help.

Two new European missions are go!

At 13:12 UTC today, two European observatories blasted off without a hitch onboard an Ariane 5 rocket from Kourou, French Guiana. Controllers in Germany confirmed readings from both spacecraft about 40 minutes after liftoff, following their half hour flight and deployment from the launch vehicle. CEO of Arianespace, Jean-Yves Le Gall, described the launch as “perfect”. Both spacecraft are now en route to their designated L2 point approximately 1.5 million kilometers away.  Now, both of these missions are actually a really big deal for astronomy…

Firstly, we have Herschel. To me, infrared astronomy is by far the best astronomy! By observing the infrared, we can really draw a lot information about the structure, and particularly the formation of stars and galaxies. Since its launch in 2003, I have been an avid follower of NASA’s Spitzer Space Telescope (named for the great Lyman Spitzer) and it continues to make astounding discoveries and send back beautiful images to this day (though now on borrowed time – it is expected to run out of helium coolant “at any time”.)

Spitzer has peered into stellar nurseries to show us baby stars, and revealed the intricate structure of Andromeda’s inner dust lanes. Now, Herschel (named for William Herschel: discoverer of Uranus) will become the new standard in infrared astronomy. It has a massive 3.5 metre Cassegrain telescope, making it the largest space telescope ever launched, and crucially, it will bridge the gap between previous space-based infrared missions and ground-based observations, by observing a waveband of ~55-672µm. Herschel’s huge mirror and cutting edge photometric technology will allow it to observe some of the coldest and most distant objects in the known universe. We can expect a lot of amazing science to come out of this mission.

Herschel (left) and Planck

Then, there’s Planck. This spacecraft, named for the German quantum physicist, Max Planck, is the third generation Cosmic Microwave Background (CMB) mapping probe. It is the successor to WMAP (2001) which itself followed COBE (1989) and its principal mission objective is to measure the polarisation and intensity of anisotropies in the primordial CMB radiation that permeates the universe as a remnant of the big bang. It will also be carrying out a number of other scientific tasks, including measurements of our own galaxy’s magnetic field. Its scanning sensors will achieve several times the resolution of WMAP, with around 10 times the sensitivity, and the findings of this mission will be extremely exciting for cosmology buffs, as they will actually help us to understand the size and shape of the whole universe.

Personally, it’s thrilling for me to see these two great missions launch together in yet another flying success for Arianespace and ESA. These spacecraft will greatly influence our understanding of cosmic origins in several years. Excited? You should be!
