Nancy Grace Roman Galactic Plane Survey – Gravitation signals from many alien civilizations

Nancy Grace Roman Space Telescope,  If I were going to look at the Galactic Plane now, I would look for evidence of civilizations of two types.  The human species is going to produce intelligent machines. Their size and shapes and abilities are open. But in terms of human knowledge one very likely outcome is that human

$Million-wise and $100 Trillion foolish – precise field technologies

Ariane Briegel, @BriegelAriane Finally- a book on cryo-electron tomography, written by leading experts! Edited by the one and only @FriedrichForst1 and myself! https://link.springer.com/book/10.1007/978-3-031-51171-4 Replying to @BriegelAriane and @FriedrichForst1 Ariane, I am sure you did good work, but I have a few comments about your method of sharing. I hate to see good things locked up

Humans can colonize Milky Way Galaxy through intelligent devices, and search for gravity signals

Humans can colonize Milky Way Galaxy with intelligent devices, and search for gravity signals. — Galactic civilizations using intelligent devices can live billions of years. So the most likely “species” for human devices to meet would be intelligent devices. Nancy Grace Roman Space Telescope might look for intelligent messages in the galactic plane. And space

Why did I work on certain problems all my life? The Chemical Bond Approach, Passion Without Guidance

Passion Without Guidance. My first year of high school was 1963/64 at Eau Gallie High School just across the bay from Cape Canaveral where my Dad was working. Kennedy gave his moon speech at Rice University on 12 Sep 1962. Within a few months, my Dad left his old job in Texas and moved our

Mapping Interiors of Black Holes with Many Sensors

Physical Review Letters @PhysRevLett Microscopic Origin of the Entropy of Astrophysical Black Holes: A theoretical proposal presents a framework for microscopic explanation of the entropy of astrophysical black holes https://go.aps.org/4agoY6i https://pic.twitter.com/53Aoni9R8A Replying to @PhysRevLett How many astrophysicists does it take to create a 3D volumetric model of the interior of a black hole region? 13.

Sub nanosecond flash 3D video sampling allows gravitational imaging, “imaging accelerometry”

I am interested in your “double exposure”. 200 ns would be 5 Mfps. Can you say which specific cameras from Imperix or elsewhere can support that? I am also interested in LWIR “thermal” camera for passive radiometry. Do you have anyone interested in camera interface standards? There are many cameras, and the cost of storing

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

Stable orbits inside central black holes

Physics World @PhysicsWorld New calculations that combine quantum mechanics with Einstein’s general theory of relativity suggest that gravastars could end up nested inside one another like a Russian Matryoshka doll https://ow.ly/kbNM50QVQGm Replying to @PhysicsWorld You should also find that any number of stable orbits of neutron and quark stars can fit inside a central black

Universal Positioning System can use gravitational electromagnetic 3D volumetric recordings

https://www.cambridge.org/core/journals/international-journal-of-astrobiology/article/pulsar-positioning-system-a-quest-for-evidence-of-extraterrestrial-engineering/E4CCF6D8F46B4B64F7AB99972C30903E Found this paper looking at neutron/quark/gluon star interiors and gravitational waves. But the idea that civilizations might be detected by their use of unique signatures embedded in their communication struck me as useful. “Earth’s sun” is not a sequence of text characters but a unique all possible frequencies large data signature of the mass
