This warp is caused due to the magnetic effect of the surrounding Dwarf Galaxies that influence the hydrogen gas in the Milkyway galaxy. It gets this particular warp because the Dwarf galaxies are believed to be moving in dark matter that is believed to be about 90% of space.
The Magellanic Clouds or Dwarf Galaxies cause vibrations within the hydrogen layer of the Milkyway galaxy and thus, produce an effect reminiscent to that of 'A tablecloth flapping in the wind'
I am going to use this in my final animation to represent the 'Infinity' or 'an ongoing process from which there is no escape.'
