Susan Parker Note about soft xrays and the gravitational potential

Hello, Susan,

There was no indication of a new message, I just happened to look.

LIGO shares some data, but there is a big difference between putting files online and actually sharing. The amount of fiddling they put into their strain data makes is nearly impossible to use without substantial insider information. They did put some of their “environmental” data – from seismometers, magnetometers, and vibration isolation system in the LIGO front end online, after I bugged them. And they seem to be holding some workshops. But they have not learned how to post data that anyone can use – without massive hand-holding and memorization. Most of those global scale experiments only serve the few principle investigators’ interests, then a platform for generating papers and dissertations. Not true data gathering and sharing. None of them check what the world needs first. Almost no effort to simplify (without loss).

“My interest is in noise and how to dig out signals in very fast pump-probe pulsed laser setups”

The pump probe literature is extremely rich and useful. Is this you, Mrs Susan Parker?

I have been looking for low cost soft x-ray sources. I found you on ResearchGate and followed you. I see you listed as an author for Apparatus for soft x-ray table-top high harmonic generation at

I found that the gravitational potential field at the surface of the earth has an energy density equivalent to about 379 Tesla magnetic field, or soft xray field with mean energy of about 358 electron volts. If you measure the soft xray spectrum along the vertical, north and east directions, some portions of the spectrum should correlate with the sun moon vector tidal (Newtonian sun moon tidal acceleration). The gravitational potential field is chaotic and is a mix of gravitational, magnetic and electromagnetic sources. I doubt you are interested in my view of things, but that is what I found after trying to make sense of the gravitational energy density. Joe Weber (Weber bars) told me he wanted to use gravitational fields for communications, and strongly encouraged me to follow Robert Forward. Robert had that expression for the gravitational energy density. In the gravimeter arrays the horizontal noise is higher than the vertical. And the best model and picture I can come up with is a dense fluid or gas. The average mass is that 358 electron volts, the speed is the speed of light. The number density is 1639 moles/meter^3.

Right now I am trying to help the groups working on spinal cord bypass. Measuring the intentional signals from the brain or peripheral nerves, bypass the damage (“neuroma”) and stimulate below. Or just use the signals directly for a wide range of neural interfaces to useful machine and processes. I have followed “femtosecond” “lasers” since they were first found. That is the time resolution needed for many things. But the cost of parts and people is so high, these things never seem to get out into the real world for everyday uses. The soft x-rays should allow deep microscopic spectroscopic imaging. Correlating that with the “traditional” EEG, MEG, EMG, EKG, NIR, focused ultrasound, modulated focuses ultrasound should allow getting low cost sensors with good reliable calibrations to substitute for methods that are not so portable.

The fastest way to look for a gravitational potential or gravitational potential gradient connection to the soft xray spectrum would be to take one meter distances of time resolved transmitter receiver and simply watch the noise over long periods. For gravimeters and seismometers I use a month of data. The photons in the soft x-ray region can be thought of as small pulses with mass, they will change trajectory with the local gravitational potential. So it would be like a atom interferometer, but using a “mass” that is about 1/1427 of the electron mass. That is heavy enough to remain stable in the smooth but still turbulent at small scales flow of the gravitational potential fluid.

Over short time periods, milliseconds, microseconds, nanosecond – the fluctuations will match magnetic and electromagnetic sources. And the way to separate and image and characterize those source, is to use time of flight. – which the femtosecond pulse groups should have down pretty solid. I can think of some atomic clock applications. But almost always when I think of things, there area alway ten thousand groups already working on them, and I just go and profile and summarize where they fit into the global research network that is implicit, but not yet explicit, from what is on the Internet.

Parts of the noise soft xray spectrum should correlate with gravitational field changes, part with magnetic field changes, part with electromagnetic, part with infrasound, part with neutrino flows, and part with electron flows. There are “diffuse photon” streams, but I have not got them into a neat box yet. I try to cover the time spectrum from nanoHertz to ZettaHertz. That is most of what is “low cost” now. The range of femtoHertz to PetaHertz is where I am trying to standardize.

I worked much of the night and was going to rest, but two things came to mind. Index of refraction and Mossbauer gravitational measurements.

You can do a three axis measurement in vacuum, but if you use a gas or liquid, those mass flows pick up more gravitational correlations. The time dilation equation has two terms, one for gravitational potential and one for velocity. The velocity can come directly from the Jet Propulsion Labs Solar System Ephemeris where they give the Chebychev polynomials for that. Or use their online Horizon system. Minute by minute is usually sufficient for a first look.

Anyway plug the values for the potential and velocity into the equation and get the ratio of the standard time rate to the rate with gravity and velocity. That can be expressed as different average velocity, or as a change in index of refraction. My own early days started with electrodynamics, so I tend to think of the gravitational potential changes as changing the vacuum index of refraction, which changes the rate of clocks at that location. The Mossbauer experiment was the first direct gravitational potential experiment. It is just the gravitational energy needed to life a photon or pulse from one height or location to another – where no external energy is added during the journey except gravitational field inputs. I like Mossbauer because it is elegant and can be low cost. There are lots of piezoelectic and electrokinectic devices. The reference signals are very precise and the energy resolution can cover the soft xray region easily, and down further. I have been trying for the past few years to generalize “mossbauer” for any chemical reaction or scattering or diffraction experiments where the initial and final momenta in three dimensions are resolvable or an be reasonably estimated. I had to look (pretty tired) and 1 mm/second is 48.075 nanoElectronVolts.

Groups work on pairs of these phenomena or dimension mostly. A few go to several dimension in their experiments. But because groups mostly don’t put everything in standard form, and share the raw data so that others can try different or related algorithms, not much progress is made to bring many different phenomena into frameworks where thousands or hundreds of thousands of groups and people can work together on core (not losing anything) models and data sets. Some is the high cost of computing and memory until now. And the narrow interests of exascale and high performance computing groups. They ignore things like “mossbauer” or “Franck-Hertz” or “big G” experiments because not enough data is gathered. Once there is a place to put and share and work on experiments made by many different groups around the world, then the gravitational variations will start showing up, be quantified and allow global imaging and communication arrays.

When a gravitational wave strikes a planet or sun, the local potential will focus it. I had hoped that “gravitation” would be a separate and independent process, but over the last 15 years, and since Aug 2017 particularly, I have had to treat them as part of one field – right now with lots of eclectic and sometimes too complex translations needed. But one the interface between two groups is worked out, they can be used as a new combined group. It has taken me so many years to learn all the different ones and connect them. The groups themselves can do it, but private jealousies, self-interest, lack of time or lack of interest trump global needs almost every time.

I have not read your papers or traced out your connections, so I cannot guess what you might want to do. Perhaps you can write and tell me. I will check “soft x-ray” “microscopic” “nerves” with its 31,100 entry points later. I am trying to profile all the efforts to put them into a simple framework. I want to be able to look up groups based on the current technology. “I need a group who can see ultrasonic frequency variations in specific indicators of molecular structure on the inner membranes of lymph vessels” – that sort of thing. It means a lot of queries and reading now. Trying to get help with mining PDFs and the Internet. When someone does a review of a topic and covers hundreds of papers, we consider them passionate and devoted. When someone reviews thousands of papers it is heroic. Now what do you do when routine merging and comparison of hundreds of thousands of sources is needed? Well that gets lumped into “big data” and “machine learning” and those groups almost never care a whit about solving global problems, unless they can patent it and milk it for themselves. Sorry, that is what is limiting global communities now. A few groups learn something, just a tiny portion of a larger problem, then they hoard it and can completely extinguish growth in a thousand times larger industry.

There are three and more LIGO detectors now that give strain data at 16,384 samples per second. That is 8,297.9 meters. They could track the moon and random regions nearby. What they should find it that the noise spectrum from a focal spot inside the moon is different from the noise spectrum of a point in the vacuum nearby. I have been calling that “moon, not moon”. It is the simplest experiment that I can think of to test if the gravitational potential field is turbulent. But when I looked at the strain data streams, they left in so much instrumental noise, it is a pain to separate. Maybe I am just too tired, but getting that into a workable FFT, getting the instrument response functions it too tedious for me. That is already done well, but not is a univerally usable form.  You can’t just bolt into it, without using their software development tools and eclectic methods.  I am good enough to get through anything, but any more I say, why bother.

The JPL Horizon vector positions are easy – I see they just changed the interface. I have been bugging them for years now. I talked to them about using surface gravitational imaging arrays to measure the speed of gravity (how I got into that) and to measure G by lab experiments as part of calibrating each instrument. It is more precise than GPS and does not suffer as much from ionospheric interference. Sorry, I work on so many things, for so many years, with so many groups, it is hard to remember them all now. That seems like a very useful one, but it needs lots of number crunching and people to write it out in those nice papers.

I hate “paper” because it forces human readers and human memories into every critical path of every important global issue. I call it a global game of “whisper” or “telephone” one group whispers in the ear of another group, they write what they thought they heard, and so on. At the end, the original data and message is lost. That, after massive duplication and untraceable sources, and human greed, is the main reason for “covid” killing millions and taking so long. Likewise “global climate change”, “atomic fuels”, “cancer” and that long litany of problems you have heard all you life but never get solved or mastered.
