Still, this sounds like a DDOS attack, which is directed and not just background radiation from Santa's robotic elves eager to sell us Laplander porn or freeze dried reindeer steaks or whatever. It didn't take out other sites at random, did it? And it came a day or so after several of us had posted some highly critical comments on the Letters to the President (US) thread. (Nothing quite as effective as shitty government to ratchet up Kafkaesque levels of paranoia) This is my post (uh oh), and note the three following it, especially MigL's last line. https://www.scienceforums.net/topic/135496-messages-to-the-president/page/4/#findComment-1305023 You see why I'm wondering about what @exchemist referred to as "some shadowy organisation." I agree with him, it seems unlikely, but still...

And yet you keep coming to this website and engaging in extended conversations with us on a vast range of issues and interests. Odd.

Worthless? Now, now, perhaps it runs on zero point energy. Why let a basic QM violation stop us from releasing some ZPE? 😜

Dear malignant manchild of the United States, Thanks for your gross violation of the memory and legacy of John F. Kennedy, by putting your name above his on the Kennedy Center. Though you are an inflamed ass pimple on the Presidency, you have shown your superiority to JFK at petty and puerile political games and narcissistic posturing. In this very narrow category of achievement you are a BIG WINNER!! However, I would ask you to honor the basic concept of a memorial dedication of a building by kindly dropping dead. Thanks!

Which is the problem I referred to with Russell. Physical spacetime is expected to be quantized because physical coordinates are slightly noncommutative, right?

OP seems like something related to Zeno paradoxes. Bertie Russell, based on Cantor, offered a solution known as the "at-at theory of motion". It has problems too.

Seems like an imaginative sci-fi pastiche of Robert Sawyer (see his "Wake" trilogy) and JL Borges. Some day maybe.

One could distinguish between knowledge and information, however. Infinite universes would require infinite information to describe every particle, field, and state, yet that could be reducible to a finite algorithm. This gets into Shannon's information theory and probably for another thread. With recursion and looping, it could be in principle a possibility that all those universes of knowledge could be compressed to some lines on a single sheet of paper. Whenever you wanted to turn your attention on, say, Percival Shmeebly in Universe #3456790, you would just run the algorithm and then decompress the resulting Shmeebly History string. So there could (again, in principle, not necessarily in reality) be vast inhuman minds somewhere which can in principle become Percival Shmeebly whenever they cast their attention that way and want the full realistic Shmeebly experience. Basically you don't have to know everything all at once in order to attain infinite knowledge. Sincerely yours, Percival J. Shmeebly

You're still stuffing photons from everywhere (including a hot radio telescope) back into the star and splitting helium. Metaphorically speaking. As KJW and Swanson keep pointing out, our causality is asymmetric. My problem with trying to imagine some reverse causality with gravity is that it's like trying to have Ricci curvature "the other way." Scorched shuttle parts rising up out of the Australian Outback and going up into space. With something like beta decay it's much easier, with a distant neutrino and an electron from my Geiger counter converging on a more stable nucleus in some radioisotope lump. Still makes no sense thermodynamically.

As with other waves, so take the analogy of EM for example: observation is of light moving away from a star, but not photons out of nowhere converging onto a star, splitting helium into hydrogen in the core. Both are valid solutions but....well, thermodynamics. Entropic arrow.

Brilliant. But wonder what chilling Rhine water will do to riparian and deep water ecosystems. Many flora/fauna are temperature sensitive. They being Germans, I have some hope they worked this out, maybe the volume of water used and chilled isn't enough to make a significant difference. ETA: it looks like the fraction is tiny. Rhine flow rate gets up to over a million liters/sec along the Upper Rhine where Mannheim sits. And near three million at the Nordsee. (BTW, do not trust Google AI on river flow rates - go directly to technical sources)

If you're planning to be naked, probably best to choose the Amazon rather than Alaska. Heh.

Also prepared for conspiracy theories to blow up all over, so long as we have no information on who murdered Rob Reiner yesterday, a prominent Trump critic. ETA: As I typed this, I checked the newsfeed and now see they're arresting Nick, their son, as a suspect, so maybe this won't get spun out so much. Still a horrible thing. I so admired his movies and his political activism and just him as a really great guy. ETA: If you are a decent human being, and have any hypertension tendencies, do not read the utterly vile and sickening SM post from Trump today on Reiner's murder. I couldn't finish reading it. And the White House official website REPOSTED it.

I should remember to tell our damp mop and brooms how much we love them. Don't want them rising up like in that Fantasia scene.

I am speechless! And in need of duct tape myself* before I say something excessively flattering about your niece. But really, that is serious talent, and skillful prestidigitation. * Not that duct tape is terribly effective at stopping keyboard use.

That IS interesting. I knew it was standard in the smaller and domestic species (leave a new empty box sitting anywhere in our house and there will be a member of Felidae there within five minutes), but hadn't thought about the big cats. Leave a refrigerator box out on the savannah, see what happens...😀 TIL the origin of "bellwether." A wether is a castrated sheep. Put a bell around the neck of the lead wether and you can hear where the herd is going even if they're out of your line of sight.

Yes, that can he a big adjustment. In my neighbor state of Minnesota, there's a large Somali diaspora and, aside from the overall climatic shock of being in one of the USA's coldest and snowiest locations, an issue with vitamin D absorption. (Generally, my impression is that the places with forbidding winters are often the most welcoming in the US - perhaps because the winters reinforce the idea that we all depend on each other and general good will in order to survive?)

Also a huge problem here. I call them "border problems." With fifty states so many people are only an hour or two from another state with potentially different restrictions. In one state I lived in, the border was fifty minutes away from the two largest cities and there were enormous stores right on the border selling dangerous (as in, children regularly losing fingers and eyes) fireworks that were illegal in our state. This is the sort of craziness that eventually spurs Washington to step in and make a federal law.

Because it's a site setting and not a global one. Probably somewhere back there in the mists of time you got some prompt or query that asked if you wanted to have an offline copy of the homepage. If you go to browser settings, there should be some kind of site settings menu choice - I think. I don't know much about Apple browsers. Speculating here.

Heehee. My interest is (harrumph!) purely scholarly and it's entirely coincidental that I happen to focus mostly on the traits of pretty women. When I observe these phenotypic traits, I do so to better understand the complex interplay between.....sorry, I forgot the topic.

Yeah, there is a lot of slop, when you have five types of RS, and then also half a dozen types of soluble fiber and insoluble fiber all interacting with the gut colony in various ways. I recently was aware of some friends who were swearing off FODMAPs, as if that was a longterm diet, and I had to warn them that a lot of FODMAP foods are really good for you and you curtail them only temporarily (working with a physician ) to get relief from serious IBS symptoms. After that, the strategy is to work with probiotics and prebiotics and mechanical roughage and vitamins, etc to normalize your intestinal colony and redevelop a tolerance for FODMAPs. I used to work with a food chemist and nutritionist who related an experience treating gut problems in an Alaskan population and finding that vitamin D supplements wrought improvements in people who weren't eating fatty fishes and so were especially deficient (Alaska not being big on sunshine) in a vitamin now linked to a healthy gut microbiome. That's just one example of another component in the complexity of gut health and where they're only beginning to understand the molecular signaling pathways with vitamin D, the gut barrier, microbiota, and the development of IBD. (Nigerians: you probably have less need to worry about vitamin D...)
