Found some quotes and videos relating to this topic (mostly)... questions posed to the 'popular' physicists of our time regarding the nature of consciousness and the mind/body problem....
- Tons of videos if you peek around, w/ Roger Penrose, Alan Guth, Michio Kaku, etc. Some interesting stuff, not necessarily re: higgs field, but I thought you might find them interesting.
A Michio Kaku quote:
"We also touched on the 'mainstream' view that human consciousness is simply an epiphenomenon of the brain - which in many respects, does not match up with the supreme importance that some branches of quantum physics accord consciousness. Professor Kaku agreed that "consciousness is one of the great problems facing science," and stated plainly that despite the mainstream view, "most scientists cannot even define it, let alone explain it." To illustrate how consciousness is important to quantum physics, he discussed the well-known "Schrodinger's Cat" paradox, and then explored various theories which might explain it. One of those was put forward by Nobel Laureate Eugene Wigner - he assumed that consiousness is the key factor in creating reality. Furthermore, extrapolating Wigner's theory means that, as Professor Kaku put it, "eventually, we need an infinite chain of observers, each watching the other... Wigner implied that this chain was a cosmic consciousness or even God.""
MK: Consciousness is one of the great problems facing science. Some have claimed to have "explained" consciousness. But actually, most scientists cannot even define it, let alone explain it.
Consciousness enters quantum physics because of the Schrodinger cat problem, perhaps the greatest paradox in all of science. If we put a cat in a box, and point a gun at the cat, which in turn is connected to a geiger counter sitting next to uranium, then we physicists describe the system as the sum of two wave functions. In one wave function, the cat is dead. In the other, the cat is alive. So, before we open the box, the cat is neither dead nor alive, but exists in a nether state. Once an observation is made, the cat suddenly "chooses" one state or the other, and we can then see that the cat is dead or alive (but not both).
(Most people find this paradox silly, but it troubled Einstein for decades. He would ask his guests at night: does the moon exist because a mouse looks at it?)
There are several ways to resolve this puzzle. The standard theory is to say that observation determines existence. So opening the box and making the measurement collapses the wave function and determines the state of the cat. This assumes that the sub-atomic world is different from the macroscopic world, that there is a "wall" separating the two. In the microworld, electrons can be two places at the same time, disappearing and reappearing all the time. But in the macroworld, cats are either dead or alive. (Lately, this standard picture has fallen into disfavor because, in nanotechnology, we can smoothly go from the macroworld and microworld and we do not encounter any wall.
Another way, pioneered by Nobel Laureate Eugene Wigner, is to assume that consiousness is the key factor. Only conscious observers can make observations, and hence consciousness causes the wave function to collapse. But how do we know that we are alive and not dead? Hence, we need a third person to observe us to collapse our wave function. But then we need a fourth person to observe the third person and collapse his wave function. Eventually, we need an infinite chain of observers, each watching the other. Wigner implied that this chain was a cosmic consciousness or even God.
There is a third way, which is gaining popularity among physicists. And this is that the universe splits in half everytime an observation is made. In one universe, the cat is dead. In the other universe, the cat is alive. The beauty of this approach is that we do not have to introduce any "wall" or "collapsed waves." The wave function merrily splits continually, creating infinite numbers of parallel universes. (We don't see all these parallel universes surrounding us, because we have "decohered" from them. Our wave function is no longer vibrating in unison with these other universes, so we cannot easily interact with them. Otherwise, we would bump into versions of ourselves where we made different choices in life, or bump into universes where people how have died in our universe are still alive.)
