I cant say that I believe crop circles are created by UFo's or not - my tendency is to discount them all out of hand as fraud. However I do agree
that sound waves and in particular sine sound waves have an ability not greatly understood nor implemented in current technology. Sound waves being
used to move heavy objects has been dicussed in rather great length before , especially pertaining to the construction of the pyramids and other large
ancient monuments and I tend to believe that there is more to the subject than out there in the main stream.
Some finer points:
Sound is a waveform that travels through matter. Although it is commonly associated in air, sound will readily travel through many materials such as
water and steel. Some insulating materials absorb much of the sound waves, preventing the waves from penetrating the material.
A sound wave has characteristics just like any other type of wave, including amplitude, velocity, wavelength and frequency
The amplitude of a sound wave is the same thing as its loudness. Since sound is a compression wave, its loudness or amplitude would correspond to how
much the wave is compressed. It is sometimes called pressure amplitude.
The speed or velocity of sound in air is approximately 344 meters/second, 1130 feet/sec. or 770 miles per hour at room temperature of 20oC (70oF). The
speed varies with the temperature of air, such that sound travels slower at higher altitudes or on cold days
Wavelength is the distance from one crest to another of a wave. Since sound is a compression wave, the wavelength is the distance between maximum
compressions
The frequency of sound is the rate at which the waves pass a given point. It is also the rate at which a guitar string or a loud speaker vibrates.
Frequency is also called the pitch of a sound. It is called the note in musical sounds
Sound is a mechanical wave ( unlike an electromagentic wave like light or radio waves ) and thus requires a medium of some sort ( of particles of
matter ) to travel through ( ie . air , water , rock , steel etc - you get the idea ) Sound waves will not travel through a vacuum - so in space
sound is of no real utility - in atmospheres and in water or soil / rock - sound can be utilized .
Now my basic theory:
It is not just sound waves that where utlized by the ancients to move these huge stones ( sorry to go off topic a tad ) but rather a combination of a
self propagating sound wave and its accompanying shock wave.
"Unlike ordinary sound waves, the speed of a shock wave varies with its amplitude. The speed of a shock wave is always greater than the speed of
sound in the fluid and decreases as the amplitude of the wave decreases. When the shock wave speed equals the normal speed, the shock wave dies and is
reduced to an ordinary sound wave."
The ratio of the speed of a moving object (v) to the speed of sound (c) in a fluid is known as the Mach number in honor of Ernst Mach (1838-1916), the
Moravian physicist, psychologist, and philosopher who studied sound and ballistics.
The Mach number is a dimensionless measure of speed common in aerodynamics. Mach 0.5 is half the speed of sound, Mach 2 is twice the speed of sound,
and so on. Speeds less than the speed of sound have a Mach number between zero and one and are described as subsonic. Those greater than the speed of
sound have Mach numbers greater than one are a described as supersonic. Speeds approximately equal to the speed of sound have Mach numbers
approximately equal to one and are described as transonic.
The shock wave from a supersonic object is a cone composed of overlapping spherical wavefronts. As any one of these wavefronts forms, it propagates
radially outward at speed c and acquires a radius ct. At the same time the source, traveling at speed v moves forward vt. These two displacements form
the leg and hypotenuse, respectively, of a right triangle and can be used to determine the Mach angle at the vertex of the shock cone.
When an object travels slower than sound, the ratio in this equation is greater than one, and the equation does not have a real solution. This makes
absolute sense as there is no shock wave to speak of at subsonic speeds. Traveling at the speed of sound makes the ratio equal one and results in a
Mach angle of ninety degrees. At transonic speeds the shock wave is a wall of high pressure moving with the object, perpendicular to its velocity.
Above the speed of sound, the ratio is less than one and the Mach angle is less than ninety degrees. The faster the object moves, the narrower the
cone of high pressure behind it becomes. Measuring the vertex angle is thus a simple way to determine the speed of a supersonic object.
Thus utilizing a supersonic device that radially exudes a cone of ever increasing pressure ( in proportion to its speed - faster the object - the more
directed the cone of the shock wave ) I think it is entirely feasible to use sound to move objects .
What do you think - sorry to ramble
