If you are one who keeps rotation curves of galaxies in mind, you might enjoy this paper by Yuval Glass, Tomer Zimmerman and Asher Yahalom from 8 Mar 2024. at https://www.mdpi.com/2073-8994/16/4/387. Retarded Gravity in Disk Galaxies When I was using the network of superconducting gravimeters to put narrow bounds on the speed of gravity,

reply to https://x.com/curiouswavefn/status/1866536050090447050 Ilya Prigogine was only one of many. He did write about gravity. Nico Van Kampen When I was at UT Austin and hanging out with Prigogine’s group, there were many others around him who were as or more inciteful. I suggest you spend time and study what Nico Van Kampen was doing

I work on gravitational wave detection and imaging for fun. I studied physics and astrophysics at several universities, but then worked in international development and computer systems for organizations to make a living. I studied statistical mechanics and thermodynamics at UT Austin in the 1970s when Ilya Prigogine and Bryce DeWitt and Madame DeWitt were

That is what real “gravitational engineers” use The gravitational potential field can change its value at every voxel in space at every moment. The acceleration field is just the vector or tensor gradient. Potentials can flow. They can have turbulent flows,

Someone wished that my holidays would “sparkle”. I think about gravitational noise every day and have for a long time. Now I will think about gravitational “sparkle” during the holidays and beyond. Sferics, sparks, seismic events, explosions, cracks, radioactive decays, shock waves, collisions. Gravity is mostly collisions and things bumping around. They mostly crack

Anton Petrov: Unexplained Earthquake Light Phenomenon Finally Captured on Camera at https://www.youtube.com/watch?v=05NmTEeXvhs Anton, This argues for keeping permanent all-sky (fish eye and other name) cameras to monitor the sky above regions where there are earthquakes, like where the earth is pulling apart. Beside piezoelectric, there are also piezomagnetic materials which will change the electromagnetic fields. The

For the Love of Physics: The Hidden Connection – How Magnetism Arise from Relativity: Explained at https://www.youtube.com/watch?v=WwzB1JvsyYc When calculating the vector tidal gravitational acceleration at a three axis gravimeter station on Earth, it is necessary to use “time of flight” methods. The sun and moon positions from JPL ephemeris for the time when the signal began

Physical Review D @PhysRevD Jun 23 The space-based detector LISA @LISACommunity will search for gravitational waves using Time Delay Interferometry variables. A new Suggestion shows that different variable choices than are commonly studied can perform better in non-ideal conditions. #EdSugg https://journals.aps.org/prd/abstract/10.1103/PhysRevD.107.123531 Replying to @PhysRevD and @LISACommunity Please also look inside the sun, inside the earth,

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
