Add diamagnetic gravimeter to the list of ways to make chip scale gravimeters and their imaging networks

Diamagnetic magnetic levitation at nanoscale is one way to make chip scale gravimeters. A “gravimeter” is an accelerometer that can track the sun and moon by their gravitational fields precisely.
The three axis signal allows “gravitational GPS/GNSS” and “gravitational compass” in 3D. Array for imaging atmospheres, oceans, magma and interiors of things. After groups track the sun and moon vector tidal signals, the next step is time of flight correlation imaging and measuring the speed of gravity.
Superconducting gravimeters are expensive but MEMS, diamagnetic levitation, atomic microscope, diode laser interferometry, atom interferometer, Bose Einstein, and many other kinds of methods can (and are being) used now. Global coordination and correlation with magnetic, seismic, infrasound, power system frequencies, lightning, satellite thermal and multispectral. It ALL fits into a nice global 3D real time digital twin of the earth and solar system.
Someone out there please look at the noise from “quantum entanglement”, the “noise” in quantum computer elements — it should make a nice three axis or tensor gravimeter sensor element. Also, check the image sensors and the latest memory chip voltages and memory and image cell/pixel noise statistics. I call that “electron gravimetry” or “electron interferometry”. But all the groups at nano and picoscale now are running in fluctuations and properties of the earth’s gravitational potential and the gradient of the potential (earth acceleration field).
I found more than a dozen ways to measure gravity with chip and desktop methods at “gravimeter (track the sun and moon)” levels. But monitoring global potential changes from earthquakes, tsunamis, atmosphere, ocean currents – all are possible and being done now. Just everyone is not working together – with purpose.
The bending modes of cantilevers for more complex states are very sensitive to gravity. The laser reflection and detection for atomic microscope methods is advanced now. More groups ought to try “sun moon” tracking and also “measure speed of gravity in a lab or parking lot”. Or three axis, low cost, time of flight, high sampling rate, high dynamic range, array imaging by passive correlation. There are fairly stable gravitational sources on earth. Well imaged (3D digital twin) of the surf at big surf” locations allows calculating the complex signals at gravimeter detection stations. It is like the sun and moon, you use the very very unique pattern to solve for your position and orientation, or to determine the speed of gravity. I made videos about some of those things. And posted software on github.
It is way past time to replace those kilometer sized light based interferometers with desktop, device and portable (including drone) base gravitational sensors for imaging and other things (including communication).
Not only is LIGO inefficient, it is using resources and people in all the countries of the world who could be using low cost and flexible tools for gravity in everyday things. Maybe a prize for the best detectors. It would have to be more on the lines of “golden banana” because I live on a fixed income.
Also, as I sorted out these many groups and how they calculate things, I found that the electromagnetic groups are expanding into what many would in the old days call “gravitational”. If you use magnetic fields and electromagnetic methods to levitation, move and shape things, or to control chemistry and distributions of thigns — that can be called “gravitational enginering” or “fields of force engineering” or “acceleration field engineering”. It is NOT HARD to calculate things. And once you “digital twin something” the speed of development itself accelerates.
Groups routinely make fundamental discoveries now. The tools are out there. What is lacking is global collaboration and clear descriptions. Rather than forcing inventors to write what they do, there can be professionals with AI tools and other tools — to write clearly about how things work and how to make new industries from scratch.
