The missing light crisis

We blogged about how new evidence is casting doubt on the existence of the universe.  Scientists have also discovered a massive discrepancy between the amount of light that we can detect and the amount of light produced by galaxies and quasars.  The two are off by a factor of some 400%.   Put another way, 80% of the light in the universe is missing.  This is being called the “missing light crisis.” [Read more...]

The universe can’t exist

Put together the latest findings about the Higgs boson particle and the gravity waves that may have just been detected and, according to cosmologists, the universe should have ceased to exist just seconds after the Big Bang.  [Read more...]

Dark matter and spiritual matter?

Our increasingly weird science now affirms that there is a reality that we cannot see, feel, or perceive in any way.  And yet it makes up 85% of the universe, which it basically holds together.  What does that remind you of?

Please note that I am not asserting an equivalence of dark matter and the spiritual realm, just noting parallels, as well as the curious phenomenon of science now recognizing that some kinds of reality elude our conventional materialistic categories. [Read more...]

A Christian physicist, the Higgs particle, and an anthropic multiverse

Christian physicist Stephen M. Barr, of the University of Deleware and a frequent contributor to  First Things, wrote with some other scientists a paper on the Higgs field–an aspect of the so-called “God particle”–that is getting new attention in light of the collider that has recently assembled evidence about this mysterious yet fundamental entity.  See The Large Hadron Collider, the Multiverse, and Me (and my friends) » First Thoughts | A First Things Blog.  After the jump, a sample and a link to a very lucid popularized explanation from Dr. Barr about his findings, having to do with both the multiverse and the anthropic principle (the notion that the laws of physics are what they are in order to make possible human life).

Obeying the cosmic speed limit

Scientists have determined that neutrinos do not travel faster than the speed of light after all.  Last year, as we posted here and discussed here, an experiment indicated that they did, which would upend much of modern physics.  But apparently a timing device was malfunctioning.  Multiple replications of the experiment show that neutrinos do, in fact, obey the speed limit.  Modern physics is safe, for now.

Neutrinos totally do not travel faster than light, say scientists (+video) –

The multiple universe theory

An interesting article in Harper’s Magazine by MIT physicist Alan Lightman on how the “multiverse” theory–which cosmologists are embracing apparently as their only alternative to Intelligent Design–is throwing down the very foundations of the scientific enterprise:

The history of science can be viewed as the recasting of phenomena that were once thought to be accidents as phenomena that can be understood in terms of fundamental causes and principles. One can add to the list of the fully explained: the hue of the sky, the orbits of planets, the angle of the wake of a boat moving through a lake, the six-sided patterns of snowflakes, the weight of a flying bustard, the temperature of boiling water, the size of raindrops, the circular shape of the sun. All these phenomena and many more, once thought to have been fixed at the beginning of time or to be the result of random events thereafter, have been explained as necessary consequences of the fundamental laws of nature—laws discovered by human beings.

This long and appealing trend may be coming to an end. Dramatic developments in cosmological findings and thought have led some of the world’s premier physicists to propose that our universe is only one of an enormous number of universes with wildly varying properties, and that some of the most basic features of our particular universe are indeed mere accidents—a random throw of the cosmic dice. In which case, there is no hope of ever explaining our universe’s features in terms of fundamental causes and principles.

It is perhaps impossible to say how far apart the different universes may be, or whether they exist simultaneously in time. Some may have stars and galaxies like ours. Some may not. Some may be finite in size. Some may be infinite. Physicists call the totality of universes the “multiverse.” Alan Guth, a pioneer in cosmological thought, says that “the multiple-universe idea severely limits our hopes to understand the world from fundamental principles.” And the philosophical ethos of science is torn from its roots. As put to me recently by Nobel Prize–winning physicist Steven Weinberg, a man as careful in his words as in his mathematical calculations, “We now find ourselves at a historic fork in the road we travel to understand the laws of nature. If the multiverse idea is correct, the style of fundamental physics will be radically changed.” . . .

While challenging the Platonic dream of theoretical physicists, the multiverse idea does explain one aspect of our universe that has unsettled some scientists for years: according to various calculations, if the values of some of the fundamental parameters of our universe were a little larger or a little smaller, life could not have arisen. For example, if the nuclear force were a few percentage points stronger than it actually is, then all the hydrogen atoms in the infant universe would have fused with other hydrogen atoms to make helium, and there would be no hydrogen left. No hydrogen means no water. Although we are far from certain about what conditions are necessary for life, most biologists believe that water is necessary. On the other hand, if the nuclear force were substantially weaker than what it actually is, then the complex atoms needed for biology could not hold together. As another example, if the relationship between the strengths of the gravitational force and the electromagnetic force were not close to what it is, then the cosmos would not harbor any stars that explode and spew out life-supporting chemical elements into space or any other stars that form planets. Both kinds of stars are required for the emergence of life. The strengths of the basic forces and certain other fundamental parameters in our universe appear to be “fine-tuned” to allow the existence of life. The recognition of this fine­tuning led British physicist Brandon Carter to articulate what he called the anthropic principle, which states that the universe must have the parameters it does because we are here to observe it. Actually, the word anthropic, from the Greek for “man,” is a misnomer: if these fundamental parameters were much different from what they are, it is not only human beings who would not exist. No life of any kind would exist.

If such conclusions are correct, the great question, of course, is why these fundamental parameters happen to lie within the range needed for life. Does the universe care about life? Intelligent design is one answer. Indeed, a fair number of theologians, philosophers, and even some scientists have used fine-tuning and the anthropic principle as evidence of the existence of God. For example, at the 2011 Christian Scholars’ Conference at Pepperdine University, Francis Collins, a leading geneticist and director of the National Institutes of Health, said, “To get our universe, with all of its potential for complexities or any kind of potential for any kind of life-form, everything has to be precisely defined on this knife edge of improbability…. [Y]ou have to see the hands of a creator who set the parameters to be just so because the creator was interested in something a little more complicated than random particles.”

Intelligent design, however, is an answer to fine-tuning that does not appeal to most scientists. The multiverse offers another explanation. If there are countless different universes with different properties—for example, some with nuclear forces much stronger than in our universe and some with nuclear forces much weaker—then some of those universes will allow the emergence of life and some will not. Some of those universes will be dead, lifeless hulks of matter and energy, and others will permit the emergence of cells, plants and animals, minds. From the huge range of possible universes predicted by the theories, the fraction of universes with life is undoubtedly small. But that doesn’t matter. We live in one of the universes that permits life because otherwise we wouldn’t be here to ask the question.

I don’t understand why the theory of multiple universes–an infinite number of UNIVERSES with every possible variation, universes that we can’t even observe–is more credible than belief in a Creator!  Actually, the term used here is “more appealing.”  Since when do scientists base their beliefs on what they like?  I’m also wondering, if the infinite universes contain all possibilities, might one of them have a creator?  And how do we know that this universe, the one with the anthropic principle, might be the one that is intelligently designed?  I know, I know, I don’t understand the science, as some of you will be explaining to me, but it seems to be that the theory of multiple universes is unscientific, since it is non-verifiable, non-falsifiable, and eludes all empirical evidence.
