context_page_description: Rajlich's hypothesis is a physical hypothesis with a significance for geology. There exist macroscopic white lamellae inside quartz and other minerals in the Bohemian Massif and even at another places in whole of the world like wavefronts generated by a meteorite impact according to the hypothesis. The hypothetical wavefronts are composed of many microcavities. Their origin is seen in a physical phenomenon of ultrasonic cavitation, which is well known from the technical practice.
  The cavities are usually made inside liquids, not in solid state media. The meteorite hit should fluidize the minerals, and mechanical waves of high frequency should tear them.
  Based on the technical practice it is known that a cavity implosion inside liquid generates high temperatures of thousands of kelvins and even a shock wave. There are found many intersecting systems of white lamellae inside quartz at many localities from the Bohemian Massif.

  Based on the technical practice it is known that a cavity implosion inside liquid generates high temperatures of thousands of kelvins and even a shock wave. There are found many intersecting systems of white lamellae inside quartz at many localities from the Bohemian Massif. It can be assumed that according to high number of wavefronts transferred through the minerals and resulting high number of cavity implosions, the structure of quartz was partially disrupted during the fluidization and the distribution of prevailing pressure was respected during the transfer into a solid state. There could be then preferred a creation of denser quartz in the area of higher pressure. This means a creation of smaller basic molecular Si-O rings. The situation in the area of lower pressure could be opposite. A finding of such harmonic signature of the quartz density is considered to be an option for the hypothesis verification.
  The author of the hypothesis is a Czech geologist Petr Rajlich. It is connected with the Czech Crater hypothesis.

The Cygnus Loop is a gas with a distribution formed by a shock wave generated by a supernova explosion.[1] There is a quartz sample with hypothetical cavitation wavefronts from Ukraine in the picture below (hand specimen). A shock wave should go through it as well.
