THE BLINDING POWER OF PRESUPPOSITIONS

I am constantly amazed at the human capacity to miss the bleating obvious. We each have cherished beliefs that no amount of evidence to the contrary will dislodge. For most scientists this cherished dogmatic belief is that the material universe is all that is, all that was and all that will ever be. Take this recent article in Discover Magazine.

A universe with a beginning begs the vexing question: Just how did it begin? Vilenkin’s answer is by no means confirmed, and perhaps never can be, but it’s still the best solution he’s heard so far: Maybe our fantastic, glorious universe spontaneously arose from nothing at all. This heretical statement clashes with common sense, which admittedly fails us when talking about the birth of the universe, an event thought to occur at unfathomably high energies. It also flies in the face of the Roman philosopher Lucretius, who argued more than 2,000 years ago that “nothing can be created from nothing.” 
Of course, Lucretius had never heard of quantum mechanics and inflationary cosmology, 20th-century fields that contest his bold claim. “We usually say that nothing can be created out of nothing because we think it would violate the law of conservation of energy,” a hallowed principle in physics holding that energy can neither be created nor destroyed, Vilenkin explains. So how could you create a universe with matter in it, where there had been nothing before?
The way the universe gets around that problem is that gravitational energy is negative,” Vilenkin says. That’s a consequence of the fact, mathematically proven, that the energy of a closed universe is zero: The energy of matter is positive, the energy of gravitation is negative, and they always add up to zero. “Therefore, creating a closed universe out of nothing does not violate any conservation laws.” 
Vilenkin’s calculations show that a universe created from nothing is likely to be tiny, indeed — far, far smaller than, say, a proton. Should this minute realm contain just a smattering of repulsive-gravity material, that’s enough to ensure it will ignite the unstoppable process of eternal inflation, leading to the universe we inhabit today. If the theory holds, we owe our existence to the humblest of origins: nothing itself.
One virtue of this picture, if correct, is that the spontaneous creation of our universe gives a definite starting point to things. Time begins at the moment of creation, putting to rest the potentially endless questions about “what happened before that.” 
Yet the explanation still leaves a huge mystery unaddressed. Although a universe, in Vilenkin’s scheme, can come from nothing in the sense of there being no space, time or matter, something is in place beforehand — namely the laws of physics. Those laws govern the something-from-nothing moment of creation that gives rise to our universe, and they also govern eternal inflation, which takes over in the first nanosecond of time.
That raises some uncomfortable questions: Where did the laws of physics reside before there was a universe to which they could be applied? Do they exist independently of space or time? “It’s a great mystery as to where the laws of physics came from. We don’t even know how to approach it,” Vilenkin admits. “But before inflation came along, we didn’t even know how to approach the questions that inflation later solved. So who knows, maybe we’ll pass this barrier as well.”
"Maybe our fantastic, glorious universe spontaneously arose from nothing at all."  Really?!?!?!  That's the best explanation you could come up with?  No other possibility but this bit of ridiculousness comes to mind? This is a textbook example of Romans 1:18-22.

The wrath of God is being revealed from heaven against all the godlessness and wickedness of people, who suppress the truth by their wickedness, since what may be known about God is plain to them, because God has made it plain to them. For since the creation of the world God’s invisible qualities—his eternal power and divine nature—have been clearly seen, being understood from what has been made, so that people are without excuse.
For although they knew God, they neither glorified him as God nor gave thanks to him, but their thinking became futile and their foolish hearts were darkened. Although they claimed to be wise, they became fools
“It’s a great mystery as to where the laws of physics came from. We don’t even know how to approach it,”  That's because there are some questions that science will never be able to answer.  In fact most of science is just dabbling in magic.  We think that if we put a scientific term on it it will be more than what it in fact is . . . a great mystery.  We can observe magnetism, electricity, gravity but in the end we really have no idea what it is, or how or why it exists, and outside of a supernatural creator we are ultimately reduced to speaking nonsense in explanation.

Why Burnt Marshwiggle?

When I was a young boy, my absolute favorite books were the Chronicles of Narnia by CS Lewis.  I remember getting them for Christmas when I was 10 and devouring them.  Of the seven books in that series my favorite was The Silver Chair.  In the book two children had been sent to find a lost prince of Narnia.  They and their guide Puddleglum had traveled through the dark north lands and into a deep cavern, which was ruled by an evil witch.  There they had found the prince and freed him while the witch was away.  At the last minute the witch returned and found them in her underground castle.  She immediately had thrown incense into the fireplace and began casting a spell over them.  She had them almost convinced that there was no kingdom above, no sky, no sun and most importantly no Aslan.  All that had ever existed was her kingdom in the deep caverns beneath the world.

The Prince and the two children were standing with their heads hung down, their cheeks flushed, their eyes half closed; the strength all gone from them; the enchantment almost complete. But Puddleglum, desperately gathering all his strength, walked over to the fire. Then he did a very brave thing. He knew it wouldn’t hurt him quite as much as it would hurt a human; for his feet (which were bare) were webbed and hard and coldblooded like a duck’s. But he knew it would hurt him badly enough; and so it did. With his bare foot he stamped on the fire, grinding a large part of it into ashes on the flat hearth. And three things happened at once.
First, the sweet heavy smell grew very much less. For though the whole fire had not been put out, a good bit of it had, and what remained smelled very largely of burnt Marshwiggle, which is not at all an enchanting smell. This instantly made everyone’s brain far clearer. The Prince and the children held up their heads again and opened their eyes.
Secondly, the Witch, in a loud, terrible voice, utterly different from all the sweet tones she had been using up till now, called out, “What are you doing? Dare to touch my fire again, mud-filth, and I’ll turn the blood to fire inside your veins.”
Thirdly, the pain itself made Puddleglum’s head for a moment perfectly clear and he knew exactly what he really thought. There is nothing like a good shock of pain for dissolving certain kinds of magic. “One word, Ma’am,” he said, coming back from the fire; limping, because of the pain. “One word. All you’ve been saying is quite right, I shouldn’t wonder. I’m a chap who always liked to know the worst and then put the best face I can on it. So I won’t deny any of what you said. But there’s one thing more to be said, even so. Suppose we have only dreamed, or made up, all those things – trees and grass and sun and moon and stars and Aslan himself. Suppose we have. Then all I can say is that, in that case, the made-up things seem a good deal more important than the real ones. Suppose this black pit of a kingdom of yours is the only world. Well, it strikes me as a pretty poor one. And that’s a funny thing, when you come to think of it. We’re just babies making up a game, if you’re right. But four babies playing a game can make a playworld which licks your real world hollow. That’s why I’m going to stand by the play-world. I’m on Aslan’s side even if there isn’t any Aslan to lead it. I’m going to live as like a Narnian as I can even if there isn’t any Narnia. So, thanking you kindly for our supper, if these two gentlemen and the young lady are ready, we’re leaving your court at once and setting out in the dark to spend our lives looking for Overland. Not that our lives will be very long, I should think; but that’s a small loss if the world’s as dull a place as you say.”

Sometimes trials and pain are a good thing.  It wakes you up to that which seeks to lull you to sleep.  Sometimes one just needs a bit of burnt Marshwiggle to clear one's head from the lies that this world sweetly whispers to us.
