If the earth travels at an average galactic speeds of 1/1000 light speed, then Pospelov estimates that earth should pass through several domain walls or sheets of the cosmic network, in a few years.
|Sheets and voids|
Pierre Sikivie of the University of Florida says “It’s certainly somewhat outside of the main-stream.” “A successful detection would be very tantalizing to current cosmology.” “How would we deal with the first detection, and the waiting for the next?” Changes equivalent to a billionth of earth’s magnetic field over a millisecond are expected. The best current magnetometers can detect many signals for a range of values to conclusively prove that earth encounters these enormous cosmic sheets. Any single event could be an electronic glitch, so using five different locations on earth to record a simultaneous event is possible, using cheap inexpensive magnetometers. A true domain wall passage should show a characteristic time signature as it passes each location. The experimenters have already used the existing magnetometers to show that they could detect such correlated events at many locations.
