  1. “The frequency illusion (also known as the Baader–Meinhof phenomenon) is a cognitive bias in which a person notices a specific concept, word, or product more frequently after recently becoming aware of it” https://en.wikipedia.org/wiki/Frequency_illusion As for the rest, it’s why anecdotes are not evidence. Without a systematic study, you can’t say that these coincidences happen more than others. They’ve just been cherry-picked.
  2. I’d like to see the derivation, and also the justification that RMSE is the appropriate standard to apply. Also, if this calculation is including dark matter. If no, and you’re just shifting the curve up, then the agreement is worse at small r. You get better agreement at large r, but the issue is that the shape is wrong, so you’re not solving the problem. There’s also an issue that the SMBH masses are inferred from theory, so if the theory is wrong, the masses are wrong and everything has to be recalculated.
  3. Which would explain why their bill didn’t drop to zero.
  4. Not with water, but a closed-loop system can use something with a lower boiling point. There are a number of possibilities.
  5. Presumably the installation of a data center would include installing the power and data transfer infrastructure. The computers are Raspberry pi processors, which draw a few watts each. https://www.solarpowerportal.co.uk/colocation/could-modular-data-centres-heat-britain-s-homes-a-look-at-thermify-s-heathub “The HeatHub includes 450 Raspberry Pi processors, which collectively sit in a box the size of a combi boiler. The heat generated by undertaking cloud computing tasks contracted to the company will be used to heat a water tank over the course of about two hours.” I imagine part of the motivation is saving on real estate costs I have to wonder if any large-scale data centers could run turbines off of the waste heat and defray a portion of their electricity costs, or put these (or larger) setups where there is already heat distribution infrastructure.
  6. Some radiation has rest mass. It’s electromagnetic radiation that doesn’t, so photons are not matter. Matter has mass and takes up space. It has fundamental fermions in it, which is why it takes up space.
  7. Is there any evidence these came from the same direction? I have not seen any, nor is it obvious that we could precisely determine the origin direction, since they could have been deflected along the way. But from what I can find, Atlas came from a distinctly different direction than the first two, since it came in close to the plane of the ecliptic, and the other two did not.
  8. It’s in the title, too, so I think everyone can be forgiven for taking that as the premise, but even with that clarification I think my original point still stands - you have not shown that regular meals is anything but a recent development, in evolutionary terms.
  9. If the final numerical predictions match reality, over the entire span of the theory, it suggests that the math is ultimately the same; it might differ in appearance only because equations can be rearranged. Do you have equations that differ from GR in substance (not merely form)? You ask people to focus on this, here, but much of your thesis focuses on philosophy as well, which has nothing to do with the internal consistency of math or agreement with observation. You have tendency to just repeat yourself rather than address questions, and do so in a dismissive tone. That can’t continue.
  10. Moderator NoteNot Science News. “Lame” isn’t a substantive argument What you think carries a lot less weight than what you can demonstrate via rigorous discussion and evidence One topic per thread
  11. TheArchduke has been banned a sockpuppet of The Archduke (imagine that!), Guille Yacante, Guillermo Yacante Afonso
  12. Hunter-gatherers had free time, too. “A study back in the 1960s found the Bushmen have figured out a way to work only about 15 hours each week acquiring food and then another 15 to 20 hours on domestic chores. The rest of the time they could relax and focus on family, friends and hobbies.” https://www.npr.org/sections/goatsandsoda/2017/10/01/551018759/are-hunter-gatherers-the-happiest-humans-to-inhabit-earth#
  13. Moderator NoteEvidence supporting the Big Bang and evolution are matters of science and not religion, which are fairly easy to find at credible science sites. You are free to ask questions in the appropriate sections of the site. As for your personal beliefs: we don’t care. Preaching isn’t allowed. That’s not what a postulate is, but cosmology has models that make testable predictions, and there’s evidence that supports the proposal. That makes it science. Yes, it’s pertinent, and why your “postulate” is nonsense.
  14. Is it an evolutionary thing or a habit we developed once we stopped being hunter-gatherers by developing agriculture, domesticating animals and settling in one area?
  15. Without support this is just assertion, or opinion. Biden did not ignore the ruling, despite Jim Jordan’s claim. (A Republican lied for political gain. Imagine that!) “To make a long story short, the Supreme Court did not agree, ruling 6-3 in June 2023that the Biden administration’s cancellation went beyond the allowable “waiving and modifying” and instead constituted an “exhaustive rewriting of the statute.” After the ruling, the Biden administration did not carry forward with the program, but did try to relieve student loan debt in several other ways.” https://www.wakeuptopolitics.com/p/no-biden-didnt-defy-the-supreme-court Did not carry forward with the program = complied with SCOTUS No, I think what you said was false was because it was false. Did Biden pardon insurrectionists? The claim I was commenting on was specifically about the courts putting Jan6ers in prison. So this is just moving the goalposts. Shred away, if you can back them up with credible sources. If it’s just hot air, though…not interested.
  16. They’ve found water in the tail, via RF absorption signals of OH “During sublimation, each frozen water molecule (H2O) on the comet’s surface splits into a hydroxyl radical (OH) and a hydrogen atom (H). Thus, hydroxyl radicals are a product—and therefore an indicator—of cometary sublimation. If 3I/ATLAS were a metal spacecraft, telescopes wouldn’t detect these molecules.” https://gizmodo.com/radio-signal-crushes-alien-theory-about-interstellar-comet-3i-atlas-2000684262 Michio Kaku’s on that list.
  17. People can stop him, but many of the ones with that power refuse to exercise it, i.e. congress, SCOTUS Did they? Yes. And Trump pardoned them or commuted their sentences https://www.jan-6.com/full-list-of-people-pardoned? People were deported in violation of a court order. Funding issues defied a court order. https://truthout.org/articles/trump-white-house-refuses-to-abide-by-1-in-3-court-orders-made-against-them/ “The Trump White House has been accused of “defying or frustrating court oversight” in 57 cases, or around 35 percent of rulings or orders made against them” Most have only just gotten to SCOTUS, other don’t have to be ignored since they have bent over backwards (and ignoring protections) to accommodate him (e.g. allowing racial profiling for ICE detentions) Did he? Or did he find another avenue (i.e. law) to exercise his authority? AFAICT there was no blanket ruling against debt relief, it was using a particular legal vehicle, but multiple ones existed.
  18. https://sites.psu.edu/astrowright/2025/11/09/loebs-3i-atlas-anomalies-explained/ “Avi Loeb continues to claim that 3I/ATLAS has many anomalous behaviors that lead to the conclusion that it “might” be an alien spacecraft. He carefully hedges the probability that it is a spacecraft around 40%, which gives him plausible deniability of the bad-faith “just asking questions” variety while still making the comet sound weird enough that lots of people are thinking (or worried!) that it’s an alien spacecraft. It certainly gets him lots of TV time and fan mail. Here are why these anomalies are not indications that it is an alien spacecraft.” My doctor asked me about Atlas at my recent checkup and I assured them that any talk about aliens was massively overblown.
  19. Aren’t there already examples of this? Hieroglyphics and other early writing systems? Chinese? Japanese kanji? Logographic languages exist.

    I’m definitely right. It’s a matter of momentum, too, maybe even more than energy. Traditional rockets have to expel mass. Photons are possible, but less efficient by a huge factor Launching a 500 kg probe is one thing. Launching the earth is quite another. “once speed is gained” is doing a lot of heavy lifting here There is no inherent velocity. We do know that we’re gravitationally bound to the sun, so we know how much kinetic energy we have to add to escape the solar system. Or perhaps you need to learn some physics if you want to discuss this, as opposed to ignorantly babbling about it.
  21. We expect material for discussion to be posted here. Not via links or uploads.
  22. That’s why you can’t cherry-pick evidence. All of it must be considered/ “The jury is out” means a decision has mot been reached. But not being out yet? It implies the trial is still ongoing. It’s not. Gravity does not behave as magnetism does. Back when I was teaching I learned that you can’t take someone’s word for it. The people who do not understand often lack the requisite ability to assess their understanding, much like in the Dunning-Kruger effect. As exchemist notes, your posts show that you do not understand.

    TIL what a Jonbar hinge/point is https://en.wikipedia.org/wiki/Jonbar_hinge “the fictional concept of a crucial point of divergence between two outcomes, especially in time-travel stories”
  24. Depends on what it’s harmonic of, doesn’t it? The fundamental frequency might be e.g. 1 THz and these are the 64th and 97th harmonics. We used to get our clock microwave frequencies using a dielectric resonant oscillator fed with 100 MHz, and picking off the 68th harmonic (for Rb; 92nd for Cs. Then mix in whatever was needed to add or subtract to get to resonance)
