How does the Spiritual Realm store sDNA or the Spiritweb?
I have a theory regarding that which also connects to bronze Allomancy and the Rhythms: ripples. Matter, energy and Investiture are the trifecta constituents of the Cosmere. We know that it shares some of its characteristics with its mundane counterparts, like states of matter: solid, liquid and gas and also plasma (the Dor) so it can be assumed that it may also ripple or vibrate like matter and energy, going by the Quantum Field Theory. These rippling may cause Investiture to vibrate at certain frequencies which may be what bronze Allomancy and the Singers can hear to a certain degree. These ripple patterns might be how data is recorded in the Spiritual Realm to form Spiritwebs. This also meshes with the fact that a person's Spiritual aspect lingers on in the Spiritual Realm after their death for a while, till the ripple pattern fizzles out.
Thoughts?
