We are taught that Heat is the cause of the Expansion of Matter.
We would take this matter and come to a reverse conclusion that the expansion of Space is the cause of rise in Heat and Temprature.
The concept is subtler but can be made easier if one tries to think of this analogy. What is subtler: Sound or Light? We know the answer: It is Light!
We know Sound is created by movement of pressure-differntial-waves of moving denser-lighter matter molecules, whether it is air, gas, liquid or solid, and these mechanical vibrations are sensed by our Hearing Instrument System.
These vibrations are felt by the ear drum, carried through Ear Drum Vibrations, Hammer, Anvil and Stirrup Bones, and the Horseshoe like Stirrup vibrating on the Oval window of Innear Ear's Chochlea, which disturb the Cilliary -- hair like floating neural fibres -- in the liquid surroundings of Chochlea. These vibrations then are carried further as triggers to neural pathways onto Brain's Auditory Cortex, next to ear.
We know Light is a Photon Particle or Wave which our Eye's Lens Focus on Eye's Retina, which in turn trigger Rods and Cones Cells of Retina to create some Neural-Electrical activity that is further carried to Visual Cortex, in the rear of the head.
We know electrons interact with lights, and photons have "no mass" but electron has mass. Similary, the molecules, -- which have many electrons, and heavier protons and neutrons -- carry the changing pressure-waves from their vibrations are nothing but grosser than photon vibrations carried through light.
So what is Heat? What is Temprature? Heat is function of Temprature and Specific Heat of Matter, and the dimension of the medium where it is stored or transmitted.
We only know them because we experience them through our Motor and Sensory Cortex, which is grosser Mechanical System, even compared to the Auditory Cortex!
If Hearing is tuned to subtler and higher frquency mechanical vibrations, than the Mechanical-Sensory Cortex is tuned to Slower frequency of mechanical vibrations of matter!
Common to all this is the Space that is the medium and it is affected by Light, Sound and Heat!
So a light can increase the electron activity and make it take higher orbits - which is nothing but an expansion of Space.
What is not known to current Science but is called as Dark Energy. This is the Prana of Indians and Chi of Chinese. This is akin to Space and is a form of Energy, which is as subtle as EMF and Light!
In fact one can think of Space as a form of Energy! Confused? Think of Space we think of as a Logical and Geometrical Manifestation in our minds, and the Space as Energy is the Physical Manifestation over the Logical Space which we experience!
This Space -- and Pranic -- energy can modify the Logical Space. Is this not Einstein said? Mass and Energy modifies Space-Time Fabric? (It is actually the change in Space would change the relationship between Space and Time -- with different degrees of Space expansion/contraction -- e.g. changing the Space vs. Time Slope).
So Heat does not cause Space Expansion! The expansion of Space -- and Pranic -- Energy causes expansion of Space.
This also happens in Thermodynamics. When we burn something to create Thermal Energy, we are converting something from "denser" to "lighter" form, and this is going to cause the "expansion" of Space to conserve the Mass (and Energy).
So now you are convinced? If not, you are still a Materialist!! Ha! Ha!! Ha!!!
Now watch these videos:
Bio Telekineseis - Demonstrating Relativistic Effects and Space (Time) Modification by Energy/Mass
Still not convinced? As per Scientists, 74% is Dark Energy, 24% is Dark Matter and only 2% is Visible Matter. That emptiness of Space in the Universe carries the most of the Energy!!
