Global networks of low cost, three axis, time of flight gravimeters and gradiometers for 3D imaging of the Earth, atmosphere and oceans

Anton Petrov: Evidence of a Donut Like Structure Hidden Inside Planet Earth at https://www.youtube.com/watch?v=GljciCwOfyc Gravitational imaging arrays using low cost but very sensitive gravitational sensors can use time of flight correlation to image regions anywhere inside the earth at high resolution. There are many desktop, even portable alternatives. Atomic clocks, gravity gradiometers, many kinds of

We need global open gravitational compasses, not demos

Postholer – GIS Resources @postholer Revolutionary Quantum Compass Could Soon Make GPS-Free Navigation a Reality Revolutionary Quantum Compass Could Soon Make GPS-Free Navigation a Reality Replying to @postholer Is an atom interferometer something to look at? Yes, but this one is not sensitive enough or fast enough. Too many cooks. Too expensive R&D overhead. I

Hans Otto Meyer and the PHELEX experiment, it might make a great gravitational potential sensor

I was reviewing the life of Hans Otto Meyer who started out at Basel University, spent most of his career at Indiana University in Physics. I found him looking at photomultipliers as I was searching for calibration data on Hamamatsu detectors. Any experiments that run continuously and precisely will run into gravitational potential effects. So

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. https://arxiv.org/abs/2105.13555   The three axis signal allows “gravitational GPS/GNSS” and “gravitational compass” in 3D. Array for imaging atmospheres, oceans, magma and interiors of things. After

MOND might be several phenomena including multipole gravitational potential flows near the speed of light

https://en.wikipedia.org/wiki/Modified_Newtonian_dynamics Their a0 is 1.2E-10 meter/second^2 which is the sensitivity needed to follow the sun moon tidal gravity signal at the earth’s surface. Potential changes at the sun and moon (and on earth) “diffuse” at the speed of light and change the local gradients. Also, electrons and protons from suns – a few charges easily

Gravity GPS/GNSS and gravity compass using sun and moon tidal gravity signal

Nils Berglund: A simplistic model for tides – instantaneous forcing at https://www.youtube.com/watch?v=XH7tvGb42s4 The easiest model that works precisely is to use the positions of the sun, moon, and earth from JPL Horizon. Then for a particular point on earth (station) calculate the vector GM/r^2 acceleration of the sun acting on the station, minus the sun

Every day gravity is Newtonian, and gets more interesting at higher sampling rates

https://twitter.com/RichardKCollin2/status/1741046739237228715 Sensitive three axis gravimeters show that vector sun moon tidal signals are nearly perfectly Newtonian, only requiring three linear regressions (6 numbers) to lock a station to the sun and moon for position and orientation sensing. Many types now.   https://twitter.com/RichardKCollin2/status/1693165581329985565   This is one month for the vertical component of the vectors signal.

Many kinds of three axis gravimeters can follow the atmosphere in real time

Utilizing the Impact of Earth and Atmospheric Tides on Groundwater Systems: A Review Reveals the Future Potential https://www.researchgate.net/publication/332292753 You might want to know that MEMS gravimeters and many kinds of three axis gravimeters can follow earth tides in real time. The three axis broadband seismometers at quiet stations follow the sun moon tidal signal closely.

Nuclear and Atomic Data, effect of order of magnitude increase in precision on opportunities in global machine learning

Donnie Mason, I was just enjoying the graphs and data at NuDat 3.0.  I have been reading and using table of isotopes for over 50 years.  It is finally getting to where it is easy to use. I was looking at Q beta-, Q beta+ and Q EC for all the isotopes and the CSVs
