From Marcelo Gleiser at Nautilus:

The modern version of the unifying quest is string theory, which supposes that the fundamental entities in nature are vibrating tubes of energy instead of point-like particles of matter. Different vibrating modes correspond to the different particles we observe, just as different vibrating frequencies of a violin string correspond to different sounds. When I joined theoretical physics in the mid-1980s, the grand task was to find the unique solution to string theory: our universe with all its particles and forces. We believed success was just around the corner, that nature was indeed a mathematical code in a 10-dimensional spacetime, nine for space, one for time.

Alas, it wasn’t meant to be. Fast-forward three decades, and the scenario has changed dramatically. Physicists were shocked to find, instead of a single solution, a huge number of solutions—by some estimates, a 1 followed by 500 zeros, each a different twist in the extra-dimensional space, each generating a different universe. Presumably, each one of these has its own set of fundamental constants, numbers such as the electron’s mass and charge and the strength of the gravitational attraction, which determine nature’s physical properties. Where’s our universe among such vast number of possibilities? We do know that if we tweaked such constants by very small amounts, life wouldn’t be possible: We wouldn’t be here. In other words, we live where we live because we couldn’t live anywhere else—our universe is one of the few that allows for our existence. True enough, but as a scientific argument this buys us very little. Worse, it sounds tautological. String theory went from being the theory that would mathematically prove the uniqueness of our universe to a theory that allows a countless number of possible universes, none more compelling than the other. More.

But too far where? Thing have gone beyond the need for a multiverse to prevent fine-tuning being taken seriously as a brute fact of the only universe we know.

Aren’t we living in a post-fact world of science now? Where it is enough to just silence inconvenient information? After all, somewhere in the multiverse, the inconvenient information is not silenced, so everything averages out.

See also: Theoretical physicist: Multiverse is about how we define science: “To me, the word is now tinged with promise and fraught with possibility. It seems no more wasteful than a bower full of roses.” Not wasteful at all, if you don’t mind throwing science out.

Steven Weinberg on what’s wrong with quantum mechanics In short, it may be that his assumption that there is a multiverse, in any scientifically meaningful sense, is part of the problem. Or…?

Marcelo Gleiser: Can everything come from nothing? Even a multiverse wouldn’t solve anything, he thinks.

    Multiverse theory is an idea that may or may not be true…with no way of knowing the correct answer. It is an opinion, a faith. Nothing more.

    as to:

    We believed success was just around the corner, that nature was indeed a mathematical code in a 10-dimensional spacetime, nine for space, one for time. Ideally, the six hidden spatial dimensions would determine the physics we observe in our common three: Twist them one way, we get one kind of universe; twist them another, and the universe is different. The appeal was the uniqueness of the solution—there would be one geometry of the extra dimensions, and this geometry would tell us all. No theory could be simpler and broader-ranging; no theory could be more beautiful.

    Alas, it wasn’t meant to be. Fast-forward three decades, and the scenario has changed dramatically. Physicists were shocked to find, instead of a single solution, a huge number of solutions—by some estimates, a 1 followed by 500 zeros, each a different twist in the extra-dimensional space, each generating a different universe.

    Whereas Naturalists have no empirical evidence whatsoever that the extra dimensions of string theory, or the epistemologically self defeating multiverse, is real, Theists, on the other hand, have very strong evidence for their belief in a higher heavenly dimension and in a hellish dimension. This evidence comes from two of our strongest, most verified, theories in science. i.e. From Special and General Relativity respectively:

    And whereas, special relativity, by ‘brushing infinity under the rug’, has been successfully unified with quantum theory to produce Quantum Electrodynamics,,,

    Theories of the Universe: Quantum Mechanics vs. General Relativity
    Excerpt: The first attempt at unifying relativity and quantum mechanics took place when special relativity was merged with electromagnetism. This created the theory of quantum electrodynamics, or QED. It is an example of what has come to be known as relativistic quantum field theory, or just quantum field theory. QED is considered by most physicists to be the most precise theory of natural phenomena ever developed.
    In the 1960s and ’70s, the success of QED prompted other physicists to try an analogous approach to unifying the weak, the strong, and the gravitational forces. Out of these discoveries came another set of theories that merged the strong and weak forces called quantum chromodynamics, or QCD, and quantum electroweak theory, or simply the electroweak theory, which you’ve already been introduced to.
    If you examine the forces and particles that have been combined in the theories we just covered, you’ll notice that the obvious force missing is that of gravity (i.e. General Relativity).

    THE INFINITY PUZZLE: Quantum Field Theory and the Hunt for an Orderly Universe
    Excerpt: In quantum electrodynamics, which applies quantum mechanics to the electromagnetic field and its interactions with matter, the equations led to infinite results for the self-energy or mass of the electron. After nearly two decades of effort, this problem was solved after World War II by a procedure called renormalization, in which the infinities are rolled up into the electron’s observed mass and charge, and are thereafter conveniently ignored. Richard Feynman, who shared the 1965 Nobel Prize with Julian Schwinger and Sin-Itiro Tomonaga for this breakthrough, referred to this sleight of hand as “brushing infinity under the rug.”

    And whereas, special relativity, by ‘brushing infinity under the rug’, has been successfully unified with quantum theory to produce Quantum Electrodynamics, no such mathematical ‘sleight of hand’ exists for general relativity. General relativity simply refuses to be mathematically unified with quantum mechanics. String theory is one, of several, attempts to, by hook or by crook, mathematically unify the two theories,

    Unified field theory
    Excerpt: Gravity has yet to be successfully included in a theory of everything.
    Simply trying to combine the graviton with the strong and electroweak interactions runs into fundamental difficulties since the resulting theory is not renormalizable. Theoretical physicists have not yet formulated a widely accepted, consistent theory that combines general relativity and quantum mechanics. The incompatibility of the two theories remains an outstanding problem in the field of physics.
    Some theoretical physicists currently believe that a quantum theory of general relativity may require frameworks other than field theory itself, such as string theory or loop quantum gravity.

    Some theoretical physicists have remarked that this failure to mathematically unify Quantum Mechanics and General Relativity is ‘the collapse of physics as we know it’

    Yet, if we rightly let the Agent causality of God ‘back’ into the picture of modern physics, as the Christian founders of modern science originally envisioned, (Newton, Maxwell, Faraday, and Planck, among others), then an empirically backed reconciliation between Quantum Mechanics and General Relativity readily pops out for us in Christ’s resurrection from the dead. Specifically, we have evidence that both Gravity and Quantum Mechanics were dealt with in Christ’s resurrection from the dead:

    THE EVENT HORIZON (Space-Time Singularity) OF THE SHROUD OF TURIN. – Isabel Piczek – Particle Physicist
    Excerpt: We have stated before that the images on the Shroud firmly indicate the total absence of Gravity. Yet they also firmly indicate the presence of the Event Horizon. These two seemingly contradict each other and they necessitate the past presence of something more powerful than Gravity that had the capacity to solve the above paradox.

    The absorbed energy in the Shroud body image formation appears as contributed by discrete (quantum) values – Giovanni Fazio, Giuseppe Mandaglio – 2008
    Excerpt: This result means that the optical density distribution,, can not be attributed at the absorbed energy described in the framework of the classical physics model. It is, in fact, necessary to hypothesize a absorption by discrete values of the energy where the ‘quantum’ is equal to the one necessary to yellow one fibril.

    Scientists say Turin Shroud is supernatural – December 2011
    Excerpt: After years of work trying to replicate the colouring on the shroud, a similar image has been created by the scientists.
    However, they only managed the effect by scorching equivalent linen material with high-intensity ultra violet lasers, undermining the arguments of other research, they say, which claims the Turin Shroud is a medieval hoax.
    Such technology, say researchers from the National Agency for New Technologies, Energy and Sustainable Economic Development (Enea), was far beyond the capability of medieval forgers, whom most experts have credited with making the famous relic.
    “The results show that a short and intense burst of UV directional radiation can colour a linen cloth so as to reproduce many of the peculiar characteristics of the body image on the Shroud of Turin,” they said.
    And in case there was any doubt about the preternatural degree of energy needed to make such distinct marks, the Enea report spells it out: “This degree of power cannot be reproduced by any normal UV source built to date.”

    Verse:

    Colossians 1:15-20
    The Son is the image of the invisible God, the firstborn over all creation. For in him all things were created: things in heaven and on earth, visible and invisible, whether thrones or powers or rulers or authorities; all things have been created through him and for him. He is before all things, and in him all things hold together. And he is the head of the body, the church; he is the beginning and the firstborn from among the dead, so that in everything he might have the supremacy. For God was pleased to have all his fullness dwell in him, and through him to reconcile to himself all things, whether things on earth or things in heaven, by making peace through his blood, shed on the cross.
