Is this how crop circles are formed? Human made or otherwise?

[SMUPhysics]

#1) Crop circles are *only* formed by humans. : )

#2) No, crop circles are formed by tramping down on the plants. There are lots of YouTube videos showing how they do this.

WHat's the frenquencies were used?

[SMUPhysics]

Approximately between 2 and 3kHz.

[BURRNE]

music is math.

[SMUPhysics]

No witchcraft. All science!

smooooke on the waaater

and human reproductive cells only come in contact with each other under laboratory conditions. I have a youtube link that shows them doing it that means that's the only way it's ever done, ever.

Just an observation but the formation right and center beginning at 2:45 looks similar to a chromosome pair in metaphase of cell division.

fuck this shit... my ears are gone O_O

HHAHAHA check it out!

press these numbers in this order:

Step one:3, 4, 7

Step two: 3, 4, 8, 7,

Step three: 3, 4, 7,

Step Four: 4, 3, 4

Waht about psycho acoustics ? very subjective if you ask me.

Anyone ever noticed the correlation of the harmonic nodes of this experiment to the geometric patterns observed in the electron probability clouds? Of course, the specific shapes of the electron fields are not exact to this experiment, but could it be that, as Einstein showed that all "matter" is really energy, that all "particles" could just be the parallax of ultra-high frequency wave forms and when they regenerate harmonics it is in the form of what we observe as a particle? Food for thought!
