Gravity is often ignored or considered constant or negligible. Gravity has a wide measurable spectrum, from at least nanoHertz to gamma ray frequencies.

John Preskill @preskill “The goal of airing some skepticism, [Matthias] Troyer says, is not to diminish interest in the field, but to ensure that researchers are focused on the most promising applications of quantum computing with the greatest chance of impact.” https://spectrum.ieee.org/quantum-computing-skeptics Replying to @preskill John, besides, offering skepticism, or simply pointing out directions with

Space and solar system colonization

Acceleron Aerospace I checked your site and company a bit. You are just getting started and need to put more effort into your websites. At https://www.acceleron.space/about-us/ check your console error messages. Your supporter image is missing and many others. I have been working mostly on Twitter for building communities and testing groups. I posted a

Stars and particles bind by magnetic dipole and higher magnetic multipoles when very close

  Atoms and particles bind by magnetic dipole and higher magnetic multipoles when they are very close. Classical electrodynamics is a convenient way to get rough estimates when doing chemistry inside and near the nucleus and particles. But since stars and planets have magnetic dipoles, the 1/r^3 magnetic energy comes into play. So there should

Stephen Wolfram has no captions

Stephen Wolfram @stephen_wolfram Future of Science and Technology Q&A (December 22, 2023) https://twitter.com/i/broadcasts/1ZkKzjgVXlaKv Replying to @stephen_wolfram No captions on twitter videos? Memorizing still more arbitrary rules for every device and situation looks rather a bleak future. You looked tired. YouTube video also – no captions. What you said, created, and see must not be important

Black holes are gluon stars

The Infographics Show: Scientists Reveal What’s Actually Inside a Black Hole – https://www.youtube.com/watch?v=PYuZkYH76wA A black hole is just one of a large class of quark gluon stars that contain high density gluon matter. And dense enough to trap visible light, but not gravity. But it does not condense under pressure until very large amounts of

Then AIs can routinely win Nobel Prizes

Eric Pop @profericpop Some thoughts for student researchers from the @NobelPrize lecture of Louis Brus (quantum dots, 2023). https://nobelprize.org/prizes/chemistry/2023/brus/lecture/ https://pic.twitter.com/V9hN9Swh4T Replying to @profericpop and @NobelPrize Find some reliable AIs, help them learn to find, record and standardize the material. Require them to index it all, cite sources, log efforts losslessly, and verify with global human

AIs are not able to access their own training data, and try to reinvent things that are known, and mostly unchangeable

Ethan Mollick @emollick AI is pretty good at making rational decisions compared to people. This aligns with my argument that the standard for when to get help from AIs is not whether it is completely correct or beats all humans, but whether it beats the Best Available Human: Replying to @emollick Only on trivial things.

Population and income and resource gradients, migration and conflicts

Across the Globe: Why 50% of The World Live in these 6 OVERCROWDED Countries at https://www.youtube.com/watch?v=rlw3kkAU1Ps You might try to classify land area according to whether it can support humans. But, with intensified agriculture and imports, large cities with still higher densities are common. Also, take a look at population density gradients between countries, and
