https://en.wikipedia.org/wiki/Superdeterminism "Physicists Sabine Hossenfelder and Tim Palmer have argued that superdeterminism "is a promising approach not only to solve the measurement problem, but also to understand the apparent non-locality of quantum physics". Howard M. Wiseman and Eric Cavalcanti argue that any hypothetical superdeterministic theory "would be about as plausible, and appealing, as belief in ubiquitous alien mind-control" Those seem like two pretty diametrically opposed interpretations of what is a.... (actually I have some trouble describing what it seems to be) It is apparently a theoretical loophole in Bell's Theorem.Have any possible experiments been proposed that could test this one way or another or it probable that none can ever be devised? Can there be there any useful comparisons with the block universe idea?

I suppose I was being facetious. It is well worth considering if social skills should be taught as part of the general curriculum. I can see pros and cons (I would have run a mile-I was "expelled" from the Boy Scouts for failing the tidyness test but others might have benefitted)

Is that what finishing schools are for? A finishing school for men might fit the bill Seems a bit like Fight Club for Toffs https://www.britishbutlerinstitute.com/finishing-school-home/finishing-school-programmes/finishing-school-for-men/

So (I know some people don't like thst use of "so") I saw the optometrist and she said the floater looked a littie thin in one place She had given me a referral to an ophthalamologist in 7-10 days even though I have had no symptoms of detached retina. They offered me some micronutrient (vitrocap) seemingly to dissolve the weiss ring but I didn't bother with it(maybe down the line if it becomes annoying) As well I had a bacterial infection in the eyelid and so it will be more comfortable when that clears.

There are two measurements ,aren't there?(I assumed that the pre tunnel particle was measured and then the post tunneling particle was measured and the interval measured) (Well I might be wrong as my knowledge is so patchy) Is the wave function applied to the field?(I thought particles were excitations of the field -in qft)

I went a bit off topic and was thinking about @joigus 's disginction btw reality and causality and probably got the wrong end of the stick. I think "realism" (local realism?) has a defined meaning and use in physics (quantum physics?) that I have not been able to get my head around so far and perhaps I confused it with "reality" As for the OP it seems there are time lapses that can be measured as well as distances but ,perhaps you are saying it that the field is in both places and it is just the measurements of two particles in that field that are separated by time and space giving the illusion that one particle travels to the position of the second particle -and at a speed above c.

Is this another way of looking at it? Anything that we try to describe as a reality is always in motion. So by the time we examine the situation it is in the past. That is anthropocentric but if we acknowledge that we are part of the system being interrogated then it applies to the apparently exterior world.

https://www.bbc.com/news/articles/c99zn92g2qgo "Scientists sampling DNA in the air to monitor the spread of deadly diseases say their work could help make food prices cheaper " I can think of potato blight as a candidate but there must be much more. I wonder what they might test for.

Well done you.You dodged an almighty bullet. I think I read that the laser treatment to the back of the eye can be quite severe (a bit like a punch in the face) Anything like that?

Thanks. I passed by the ophthamologist this afternoon to book a checkup but they were closed on the Saturday. I will try again next week. Did you have any pain at the time? I have been rubbing the eye for the past 4 days.It feels like grit got in or one of those mini styes. It is just on the eyelid ,anyway but I think I read that pain could be an indication of something serious (blurry vision would be another indication ,I saw)

Does anyone else have these? I have just got myself a new "companion" in my right hand vision who twists around like a falling leaf or one of those arty mobiles. I also have "floaters" that come every 6 months and only last for 10-20 minutes perhaps. This new visual defect (the Weiss ring) seems here to stay. It goes away when I concentrate my vision or thoughts on one thing but reappears as soon as I relax. I am learning from the internet that the brain will likely filter it out in a few months although there are some people with lots of floaters who find that their life has deteriorated a lot ( eg no reading , telly or going in the sun),probably because they have very many of the floaters. So ,is anyone else in the same boat as me with a Weiss Ring? Any advice as to how to make the (hopefully short ) habituation period as unannoying as possible?

Was spacetime curved even before the Higgs field formed? There were sources of gravitation then separate from mass? I was confused in the OP and imagined that spacetime came into being around the same time as the Higgs field. I now think that spacetime existed as far back as the BB(T+ 10^-43 seconds ) and that it was curved ,although I have no idea how curved it would have been-possibly indistinguishable from flat spacetime or possibly extremely curved.I don't know.

No I meant objects (interactions?) .The points ,to my mind are (relative) attributes of the objects. I understand what you said (avoiding using the word "point" ,as in "your point") about differential geometry breaking down but did I read somewhere something about some attempt at building a maths based on a "discontinuous number system?) Maybe the "objects" I had in mind would be fields. Better not ask any more questions here and get even further out of my depth..

Do you mean there could be no quantifiable relationships between distinct objects ?

Is Washington State a winner takes all of the electoral college votes? They would likely do Trump a favour by taking him off the ballot so that he could whine about being a victim and concentrate his resources elsewhere where he had an actual chance of getting electoral votes. That said ,if that is the law in the State ...

Ah yes, I must have a blind spot.I thought I understood that spacetime was just a mathematical construct but my question showed that I didn't. I think I was also probably equating in my head curved spacetime with spacetime itself -as if flat spacetime wasn't "proper" spacetime.

So spacetime existed before the Higgs field came to become a dominant force? Does spacetime work the same way if there are no sources of curvature? Or do the other fields provide sources of curvature even if there is no mass present ?(I understand ,probably naively that the Higgs field is reponsible at least in part for gravity)

Oh ,I didn't realize Cruz may have been suggesting anything like that.(or that anyone could imagine such turpitude) Can see why even Trump despised him if that is really the case.(of course despisal for Trump is merely transactional)

Well(Trump's advocate here) that is permitted ,surely.If a juror honestly disagrees with the other 11 is he or she not duty bound to vote accordingly? I don't see how that is "taking one for the team" Of course they can also be persuaded but if only 11 out of 12 is required then that should be the law. The unanimity impressed me ,whatever was said in the jury room that the verdict was strong. Any appeal might lean on the judge's instructions. I like the fact that he gave them a choice of 3 crimes but perhaps they might say it was too innovative?

I understand that the model we have goes back to T+10^-43secs. Did spacetime form then ,at that (those?) moment or did it happen when the Higgs field was created? (or emerged?) Since the time it did form ,has it evolved into what we now measure in a continuous fashion?

My feelings too.This trial was really all downside and no upside(for Trump's opponents) Did this trial delay the others at all because it was the one that the Dems would gladly have sacrificed for the others? I would not be surprised if the Trump voters paid zero heed to the outcome of this trial as far as their voting intentions are concerned. I did ,in my own mind discount the chances of an acquittal but was very taken aback by the unanimity of the guilty verdict. But then I didn't pay as much attention to the trial as those 12 jurors or the judge. Was Trump's error to think he could or should just subsume this trial into his electioneering? It was probably within reach to get a hung jury if he had taken it more seriously and respectfully(and let his lawyers do their job) He could have spun a hung jury as (a) a finding of innocence ,(b) even in New York they couldn't find him guilty and (c) they had to invent a new type of crime to try and fail to take him down("they think I am Al Capone -must have been listening to DeNiro"-insert new nickname for him and try out his Italian mobster accent) .

The sunk cost fallacy?

When I was in Paris ,aged 15 my host family took me out for the day to look at the Arc de Triomphe. As we looked at Napoleon's different victorious battles and dates that were inscribed on the monument I asked out loud and in complete naiveté "Where is Waterloo?" To complete silence . I was completely unembarassed .I think I was put right when we got home. Later I amused my friends by describing bad things as "terrible" when that actually means "really good"( a mistake categorised as a "false friend") Ps "espèce de con " or "espèce de conard" is a fine insult and "Le Canard enchainé" was the main satirical weekly magazine back then.

1s it considered at all plausible that two ( more?) universes could be created from a shared event? Or is that just "intellectual incontinence"

I wonder ,does the Planck unit of time also dilate along with spacetime curvature(under extreme conditions, of course)?
