Huh???? FWIW, for maybe 5 seconds before the Northridge Earthquake hit (I was about 25 miles southeast of Northridge), I was startled out of a deep sleep, began to discern the most frightening rumble like five million trains in the distance, and was already awake when it hit. I remember it as being the sensation of "feeling" the wave coming. I was out of bed like a jackrabbit when it jolted the apartment.
Half of your body is partices, called fermions : electrons, protons, neutrons. Each particle also is a WAVE, just like light(the electromagnetic spectrum is particles-bose photons that move like WAVES). Thus MATTER WAVES are the other, invisible, half of your body; sometimes called fermi waves.
You don’t SEE them(wavelength given by h/mv, 20 orders of magnitude shorter than 4000 to 7700 angstroms), you FEEL them as TIME; or the collapse of the wavefunction as physicists say. The speed of the matter wavecrest is given by U=c^2/v which can either be taken as c^2 mass-AREA or c^2 as momentum-LINE(9x10^16 km/sec).
Thus your body-matterwave-half felt the movement of matter in the quake even before the ground waves hit. Now, let’s see how your mind can expand to comprehend this.....
