Konrad Lehnert @Berkekey about MEMS gravimeters and other very sensitive accelerometers focused on ‘gravitational’ sources

Physics @Berkekey: Oct 13 Colloquium: Konrad Lehnert at https://www.youtube.com/watch?v=qbqTWe1qBbY Konrad Lehnert, Three axis MEMs gravimeters can be made sensitive enough to measure precisely the vector tidal sun moon signal that is the main part (about 98.5%) of the signal at a superconducting gravimeters station. Using the JPL ephemeris this is just the sun’s acceleration at the

Richard Behiel – on linear regression for 3D gravitational calibration, and 3D gravitational imaging

Richard Behiel: The Beauty of Linear Regression (How to Fit a Line to your Data) at https://www.youtube.com/watch?v=my3lsV-VQjs Richard Behiel, The vector tidal gravity signal from the sun moon and earth at a superconducting gravimeter station is simple Newtonian GM/r^2. The suns vector acceleration on the station, minus the suns acceleration on the center of the earth.

Prasad Raju – Geophysical time series

Prasad Raju,   I suggest you use online resources to look at the data. There is a lot of seismometer and magnetometer data. There is meteorological data. If you just want sources of interesting signals, there is some good solar data (solar dynamics observatory), data from lots of astronomical and astrophysical surveys. Radio telescope data

Every star contributes to expansion, every black hole region contains many bodies, the big bang was a small and ordinary event

Anton Petrov: Whole Universe May Be Evaporating According To New Study at https://www.youtube.com/watch?v=vEAKbL04bxQ Anton Petrov, I think you ought to focus on the life of any star. The matter concentrates into stars, reaches critical density to ignite nuclear reactions, and then, for the rest of the stars life, it will be radiating neutrinos, photons, electrons, protons

Illinois Quantum:”Quantum” detectors also pick up dynamic gravitational field, please check

Cindy Regal: Quantum optomechanics in interferometry and transduction at https://www.youtube.com/watch?v=zY2xn7bhMY0 Cindy Regal,  All that you said, applies to dynamic gravitational waves. I like your broadband note at 23:37 especially. But you can do a lot more.  All the frequencies (femtoHertz to TeraHertz, and beyond in both directions) are available for “gravity” and usually detectable. I have been asking

Twitter: Magnetically Levitated Superconducting Microspheres

Physical Review Applied @PhysRevApplied May 21  Editor’s Suggestion: Superconducting Microsphere Magnetically Levitated in an Anharmonic Potential with Integrated Magnetic Readout #OpenAccess: https://go.aps.org/3MGR4hv Replying to @PhysRevApplied Whenever I see “superconducting” “levitation”, I immediately think of superconducting gravimeters. They are high cost, single axis but about 0.1 nm/s^2 at 1 sps. For gravitational imaging arrays, we need

Many Quantum devices are likely potential gravitational sensors too

Snowmass Media: 23. Quantum Computing Simulation for Collective Neutrino Oscillations – Valentina Amitrano at https://www.youtube.com/watch?v=xnkInU0hwHo Valentina Amitrano, Thank you, I was trying to understand neutrino oscillations. Your different perspective helped a lot. I got an update on qubits for free. I do not know if anyone reads these comments. There ought to be a better way.

GWOSC and Auxiliary Data – Combining LIGO style detectors with all earth-based sensor networks

Correlating LIGO style strain and auxiliary data with all data from earth-based sensor networks I followed many of the pathways from this email looking for downloadable data on the Internet accessible from the browser. All I found was your groups favorite software ways to access things you are interested in. And nowhere did I find

Calibrating all gravitational sensors into a single imaging array, Measuring speed of gravity as a routine calibration for gravitational networks

https://www.researchgate.net/project/Solar-System-Gravimetry-and-Gravitational-Engineering/ Calibrating all gravitational sensors into a single imaging array: I was thinking about this some more. The gravitational potential from the sun and moon changes significantly during the year and over the course of the day. And the absolute values (for the usual network few hundred samples per second and slower) change slowly. Your
