What is the False Vacuum?



Quantum Field Theory

Quantum Vacuum:
In classical physics, empty space is called the vacuum. The classical vacuum is utterly featureless. However, in quantum theory, the vacuum is a much more complex entity. The uncertainty principle allows virtual particles (each corresponding to a quantum field) continually materialize out of the vacuum, propagate for a short time and then vanish. These zero-point vibrations mean that there is a zero-point energy associated with any quantum field. Since there are an infinite number of harmonic oscillators per unit volume, the total zero-point energy density is, in fact, infinite. The process of renormalization is usually implemented to yield a zero energy density for the standard quantum vacuum, which is defined as no excitation of field quanta, i.e., no real particles are present. In other word, the quantum vacuum is at a state of minimum energy - the ground state.


You have to be able to envision this movement in what our universe is doing. What is WMAP saying? Other events say what, in the node/anti-nodal?

A Chladni plate consist of a flat sheet of metal, usually circular or square, mounted on a central stalk to a sturdy base. When the plate is oscillating in a particular mode of vibration, the nodes and antinodes set up form a complex but symmetrical pattern over its surface. The positions of these nodes and antinodes can be seen by sprinkling sand upon the plates;


The "quantum harmonic oscillator" and "zero point as a ground state, are the basis of my thinking. :)Energy densities. I needed a way in which to see these events unfolding in the universe. Why I look at WMAPing very seriously. Why I looked at the chaldni plate very early on.

Physically, the effect can be interpreted as an object moving from the "false vacuum" (where = 0) to the more stable "true vacuum" (where = v). Gravitationally, it is similar to the more familiar case of moving from the hilltop to the valley. In the case of Higgs field, the transformation is accompanied with a "phase change", which endows mass to some of the particles


If you look at things in this way I have covered a lot of ground work in terms of what the basis of this universe is? "Nothing," is a extremely hard thing for me to accept when I accept the quantum harmonic oscillator, as the basis of my thinking. I had to be able to describe what I was seeing. So "sound" in analogy became a very important aspect of my research. Became discriptive of what Higgin's the graviton is doing?

If you sprinkle fine sand uniformly over a drumhead and then make it vibrate, the grains of sand will collect in characteristic spots and figures, called Chladni patterns. These patterns reveal much information about the size and the shape of the drum and the elasticity of its membrane. In particular, the distribution of spots depends not only on the way the drum vibrated initially but also on the global shape of the drum, because the waves will be reflected differently according to whether the edge of the drumhead is a circle, an ellipse, a square, or some other shape.

In cosmology, the early Universe was crossed by real acoustic waves generated soon after Big Bang. Such vibrations left their imprints 300 000 years later as tiny density fluctuations in the primordial plasma. Hot and cold spots in the present-day 2.7 K CMB radiation reveal those density fluctuations. Thus the CMB temperature fluctuations look like Chaldni patterns resulting from a complicated three-dimensional drumhead that


String theory is only "topologically equivalent" to the shape and values of those events microscopically/macroscopically at a certain plac einthe unfolding universe? I learnt that the energy densities flunctuations, would give meaning to the place dynamically and geometrically speaking, to the place in time, that is unfolding. What evidence do you have for that if "Higgin's" is strong in some event places and not in others? :)

The star Eta Carina is ejecting a pair of huge lobes that form a "propeller" shape. Jet-like structures are emanating from the center (or "waist"), where the star (quite small on this scale) is located.


Yes, there are many event shapes and they are diverse. But they happen within context of a "larger false vacuum" scenario as I am explaining it, while they make their way to what is "True?"

I had to "go further" then the microseconds, strings inhibit?

The plates can be made visible by mounting a mirror behind the row of plates, angled so that the top of the plates are visible to the audience (same idea as in Polarization by Scattering). Create the optimum angle for the front rows, as the back rows will be looking down on the plates anyway. Make sure the cello bow is nice and tactile by treating it with rosin before the performance. Sprinkle the sand on the plates so that it forms an even cover. Don't overdo the amount.
