Bose-Einstein Condensates & 'Absolute' High and Low Temperatures of the Universe

The phenomenon of sound occurs in the mind rather than in the world for-itself. Waveforms occur in the world for-themselves, as one might regard everything as a waveform.

That is a challenging topic for physics however. The wave function of Schrodinger and the discussion of light as a photon or wave (Michaelson-Morley experiment) are millestones on the road of discovery.

If the Universe is made of information alone as in the Holographic Theory, then bits of data could be converted into representation as sound.

Although one can see waves in the water and waves in other mediums-even gravitational waves are thought to exist by some that make ripples in space-time, it is not certain at all that at the smallest scale-if there is one, that waves exist.

The Bose-Einstein condensate is a substance that can be made by cooling neutrons down to absolute zero wherein they lose their individual identies and become one substance without motion. Motion is the basis for temperature and for energy and at absolute zero no waveforms might occur either, yet intuitively one believes that to be wrong. Even in a Bose-Einstein condensate neutrons or anything existing should have some sort of wave-motion implicitly though it may all coincide into being one wave representing all-possible locations that it could be.

One must wonder if Bose-Einstein condensates could be made to have quantum entanglement.

These things in space are wave-forms of things of quantum construction with uncertainty at the core.

The Arecibo radio telescope collects radio waves. One cannot hear radio waves without a radio to convert that wavelength of the electro-magnetic spectrum into vibrations in the air that a human eardrum will send to the brain where it is transformed into the experience of noise.

There is a powerful new radio telescope under construction in the Andes mountains of Chile. It is named the Alma Telescope (Atacama Atacama Large Millimeter/submillimeter Array telescope) and it has already taken a 'picture' of very deep space. Radio waves can be converted into light wavelengths evidently, though it is the most complex radio telescope in the world. It will be fully operational in 2013.

I was reading a book on physical constants recently and encountered the idea that temperature is motion/energy of particles/waves. The absence of motion is absolute zero-a temperature on the fahrenheit scale regarded as -459.67 degrees.

Absolute zero; the true absence of motion is said in the wikipedia to be regarded as improbable because zero-point energy still occurs and that kinetic energy is temperature.

I suppose one might regard that quantum uncertainty that is a fundamental part of quantum mechanics as a field for itself that appears do locate at particular places and times as a phenomenal artifact of observation. In the book I am reading the quantum spin states of the mass was itself considered in order to illustrate the point about temperature and motion at the absolute zero range.

The example given was I think of quarks with made one or two spin states such as up or down, right or left. Imagine that in a Bose-Einstein condensate there are a hundred quarks given the same spin state characteristics such as U(UP)-R(RIght) or UR. Then one through some means turns them all to the zero-energy setting and one has achieved absolute zero (though the nature of quanta means that they still have zero-point energy) because they only seem to be where they are because they are being observed).

The interesting point I found was that the setting below the absolute zero setting of quantum spin states (eigenvalues in shop talk) might be like that on the odometer of one electric car-at zero setting if one rolls it back further it becomes the infinitely high temperature! Below absolute zero there may be absolute hell thermodynamically speaking.

Beneath the quantum phase surface of this Universe there may be an absolute hell. Perhaps if the Universe does expand far enough for enough time that is cools down from its average three degrees Kelvin near enough to absolute zero the Universe may convert from absolute cold and entropy to an infinitely high temperature although one might reasonably guess that mass cannot have an infinitely high temperature any more than an infinitely low temperature. Mass has limits on its energy range if it is to exist at all.

At the beginning of the Universe the temperature according to the standard model of physics might have been 1032 Kelvin.

Einsteins Field Equations for the General Theory of Relativity would provide math that yields the idea that the temperature might be infinite then-however Einstein did not know too much about quantum spin states then, although he did create the idea of the Bose-EInstein condensate given Bose's mathematical concepts on photons within a paradigm of statistical mechanics. The 'infinite' value for high temperature or energy may be a concurrence of quantum spin states. At a high enough temperature mass loses its individuating cooler characteristics somewhat like a Bose-Einstein condensate does (a very different result though).
