It may be that the universe is not expanding, but viewing far off galaxies uses limited amounts of antimatter "bandwidth" that lets us see clearly to other stars. The galaxies getting harder to see are commonly mistaken for the illusion of cosmic drift acceleration and the false conclusion that everything is drifting further apart.

>in the Standard Model (SM) of particle physics, the vacuum is not truly empty, but a dynamic, lowest-energy state filled with fluctuating quantum fields and "virtual" particles.

The "virtual" particles assist with viewing far off places. The types of quantum fields in a space vacuum are "anti-matter" as predicted by the SM; the opposite of quantum fields that exist merely through the act of observing them, the "bandwidth" that is available to view other places in the galaxy is related instead to how many times they have been observed, proven by the illusion of universal acceleration being mistaken for differences in distance instead of the resistance of the antimatter theorized to be present there with the light signature data consumed during observation.

Consider that even the phases of the moon would adhere to this concept, with a full moon being caused by the lack of use of the antimatter bandwidth by the majority of the human population and a crescent moon being caused by an abundance of virtual particles in the line of sight of the majority of the world population since it exists predominately on one side of the world's elliptical orbit.

Hi Dede, basically all of this postulating came from wondering what an undiscovered opposite of the "observer effect" in physics on may be, or what effects not observing something has on it's measurements in our normal space-time dimension even if such an effect would remain "undiscoverable" due to it's nature.
>>
>>16930430
Ooh, I see. Then during an eclipse, the lack of antimatter bandwidth of the Moon (which really is an imbalance of matter bandwidth) would collide with the antimatter bandwidth of the Sun that is hidden (and therefore cannot be observed), resulting in a massive outburst of light (that we mistake for the coronal glow).
>>
>>16930481
Yes.

It could explain alot of other things, like the reason the solar corona is so hot and bright is because it is difficult to look at, resulting in an abundance of antimatter in those 94 million miles; and the reason the moon becomes transparent is because life on Earth's attention has depleted the antimatter in those 238,900 miles causing the virtual particles to obscure the energy that was visible through the antimatter in space.

Yes, which would inevitably lead to the question whether or not the more recent shift from first administering vaccines at the age of 6 (like the '60s) to the age of 1 (around the '80s) and then to 3 months (nowadays) has lead to a shift in the way developmental disabilities present in kids on average.
As it seems, fewer reports of autism with sudden regression and loss of previously acquired skills at the age of 2 or 3 are now reported, though the proportion of mental retardation in kids diagnosed with autism by the age of 6 have remained stable since the '90s at around 50-60 %. Obviously the numbers are massively skewed downwards in most statistics because a lot of autism is "falsely" diagnosed in people much older.
This would technically fit with the notion that the shift to giving vaccines earlier has diminished the number of kids suffering from anaphylactic and autoimmunological reactions to vaccines against which they developed an allergic reaction due to previous exposure.
Though that kind of getting used to vaccines should decrease autism prevalence, yet we continue to observe an increase so I'm sceptical that vaccines are the sole contribution. I suspect a significant factor that drives up autism rates are interest groups, I'm mostly looking at hedge funds and banks but also big pharma, which has captured insurance companies and insurance regulation and now deliberately diagnoses too many kids with autism to enrich investors and stimulate economic growth to prevent a recession. This would also fit well with the sudden avalanche of neurodiversity campaigns and advertisements which is disease-mongering masquerading as civil rights.
>>
>>16930129
Given the recent shift, however, that most autism cases nowadays present as less socially incapacitated relative to measured IQ, I also contend that much of today's "autism" is more akin to intellectual disability caused by long-term exposure to various products like pesticides. Then, there's the whole thing going on with the side effects brought on by the consumption of anti-psychotics and similarly which ha become normal for pregnant parents and are routinely given to children by the time they're 4. Some studies suggest that consuming anti-psychotics during pregnancy may increase autism rates by up to 800 %, for anti-depressants it's 300 %. If you go by the stats, 20 % of all women are on anti-depressants so that alone could double autism rates.
>>
>>16930130
In the end, a proper answer would involve splitting up autism into dozens of separate diagnostic labels. Something like
-Autism caused by an encephalitis/allergic reactions
-Autism caused by long-term exposure to psychotropic substances
-Autism caused by maternal autoimmune disorders
-De novo mutations and genetic defects causing autism
-Autism as a result of birth complications.
-Metabolical diseases that cause autism. They're comparatively rare.
-Autism as a side effect of medication in young kid.
Essentially, we would realize that autism is medically meaningless because it's merely a symptom present in a lot of diseases. Autism is also characteristic for schizophrenics. Yet, the medical establishment aggressively promotes the spectrum narrative which is meaningless and misleading and also declares certain issues to be "not autism" despite them fulfilling autism criteria based on mere political decisions.

>>
>>16926536
>(SSRIs do this)
That's not what they do. They force serotonin to stay in synapses longer, which is initially highly stimulatory, but subsequently does 2 main things after a few weeks:

1) Downregulates/desensitizes 5-HT receptors in general
2) Upregulates enzymes for neurotransmitter breakdown in general

When you pay attention to how this "helps" anyone, it's almost exclusively seen as good in those individuals suffering from emotional outbursts. SSRIs stop them from needing to cry or scream or otherwise cause undue emotional damage in their everyday interactions.

As far as 5-HT1 goes, that is simply focused on more because it is a better long-term target. It takes weeks or months to cause serotonin neuron desensitization. 5-HT2 has a much more rapid period of adjustment, so desensitization happens quickly and rebounds quickly. However, SSRIs have effects on both.

What I mean is that things that would have taken 50 years to discover or invent can now be discovered or invented in just 5 years. Today, we don’t draw complex mathematical equations on paper and calculate them ourselves—we use calculators. By shifting the burden from the human brain to the machine, we relieve the human brain of that load and save time as well. We’ll soon start reaping the benefits of the investments we’re making in machine learning and computing. In other words, during this era where most things are happening rapidly and are expected to continue doing so, the human brain is lagging behind when it comes to making new discoveries and inventions. That’s what I meant by “sufficient”—we’re not stupid; we just need to accelerate our progress.

One thing I really encourage anyone interested in philosophy to always keep in mind is that, nobody is going to take anything you say you believe in seriously if you only have logical reasons for believing in it, and no personal involvement in it.

What I mean is like, someone can be opposed to war in general, and have a well formed ethical argument for why war is unethical. But someone who has served a tour of duty and seen their friends get blown away has a direct, visceral reason to hate war and knows war is wrong through wisdom, not just knowledge.

Base your philosophy on wisdom, not just some trivial axiomatic reasoning. Philosophy is "love of wisdom" afterall, is it not? Not "love of knowledge". That's what science is for. They form two sides of a coin, in my opinion.

That is literally physically impossible today. Knowledge has expanded to the point that individual hyper specific sub-sub-sub fields have more data required to fully understand them than it would have taken for someone in the renaissance to be a master of all fields of science.
And it keeps getting worse every day.

>deleterious mutations can just as easily exist imperceptibly throughout the course of generations instead.
Yes. This is literally the reason inbreeding is a problem. Most people are carrying recessive alleles for some deleterious trait or another. Inbreeding raises the chances of offspring expressing these traits from ~ 1 in a million to ~ 1 in 16 (very rough calculation but the order of magnitude is what matters here).

Sorry for hanmering down this point, but it is a genuinely teachable moment.
You made a testable, falsifiable, prediction. That being:
>if sexual reproduction were the primary filter for deleterious mutations, then they'd still persist through generations if they were imperceptible.
From this, we can extract a hypothesis:
>if there are imperceptible deleterious mutations floating around, we should expect to see them become more perceptible through consanguinous pairings.
We can investigate this hypothesis by running the following experiment:
>observe frequency of congenital disorders among consanguinous and non-consanguinous offspring respectively.
Upon doing so we find:
>consanguinous pairings result in significantly more disorders than seen in the control group.

In this very short discussion, we have used the scientific method to validate sexual reproduction as the primary filter for deleterious mutations in a way which satisfies Popper's falsifiability principle.
I obviously don't expect you to concede your entire world view because of this. But I would hope you remember it next time you come across arguments regarding the testability and falsifiability of standard evolutionary model.

Sometimes I wonder what it's like to grow up with a language like Japanese, since the country was advanced enough, literate enough and exotic enough a century ago that they created their own "native" terms for scientific/academic concepts instead of using latin/greek.
Mind you, they're mostly just borrowing foreign terms directly these days, but it has to help a lot to learn science with a vocabulary you can understand at a glance.
Of course Western students a century or two ago were also expected to be familiar with greek or latin.
>>
>>16930522
As far as I can tell most languages had scientific terms that are native: German and French in particular are well known to, as some of their jargon was anglicized later.
English, and by that I mean BE, has a history of having been purposefully complicated by design to enforce a class divide on a language level. The mob was supposed to struggle to keep up with conversations of the higher class, and this practice could still be seen in more subtle ways in print media until at least the 20th century.

German sort of yes, French not really, in fact French was exporting barely francisized greco-latin academic jargon to laggards throughout the world. Native french words are rarely used outside of military theory and philosophy.

But even for german... Like compare these two pages, I don't think you need to speak either language to understand that one is far more independent from greco-roman etymology than the other:

That’s a meme. Pretty much no reactor on earth today will meltdown as severely as say Chernobyl thanks to better containment and safety systems, and even Chernobyl is far from the ecological disaster people think it. Animals live around it just fine.
Much bigger consequence will be the runoff from all the breaking down containment and infrastructure for all the thousands of chemical products we use.

Imagine a small village of 50 people with little contact with the outside world. One generation, randomly, a considerable excess of males is born, say 13/20 younglings are male. Now, if a few of them are gay, they can fuck eachother instead of fighting over the females, while still contributing to the community economically. You can imagine a "mechanism" where if a young fellow grows up with many older brothers and not many girls around he becomes attracted to men. Such a gene (or group) is favourable in the long term given the external environment/community. Furthermore, in the circumstance that most of the village's men die, a homo can still provide seed to women readily enough, even if he prefers men.

This is just a simple hypothetical scenario, but it proves the conceivability of gayness emerging through evolution. In reality there were far more complicated scenarios and evolution happened over millions of years. The details are impossible to determine as most of the evidence/information is lost, and it would be obscenely complicated even if we could look back and watch it all unfold.

Question.
If DNA was found in another star system, would it imply panspermia, or could it be that given enough time and complex biological soup, the same thing manifests over and over again?
Is it less like randomly coming up with c+, and more like randomly/iteratively coming up with a base binary language?
What I mean by that is pretend there was a 1:1 version of earth far away, and it did have lifeforms: Some with wings, some that swam etc, "they could be based on some other system/biological programming language" but if it was DNA there too, is DNA itself so complex a system that it would imply panspermia?

The way we use it, the RNA sequence transliterated from a DNA goes to a ribosome, which transforms it into specific proteins based on the sequence. That RNA sequence usually contains a leader sequence ("grab me here"), plus several start codons ("start translating into a protein from here") and stop codons ("stop translating into protein here") throughout the sequence. Change the sequence a bit and you get different proteins. Change the ribosome a bit and you also get a different protein, think of the ribosome as a... mold or something.
The shape of the ribosome itself is encoded not in "our" genetic material (the DNA in our nucleus) but in the ribosome's own RNA, and it has specific and complexly shaped t(ranslation)RNA that decides how it translates the m(essenger)RNA you give it, but they usually have one central site with a tunnel of sorts for mRNA to pass through it.
It's already very complex and it all varies quite a bit between bacteria and eukaryotes for example (in the ribosome subunits or the tRNA), but it could potentially vary even more. For example an organism could have floating enzymes without bothering with the whole ribosomal structure (many viruses use this to simply replicate their own RNA), or it could have giant ribosome equivalents with several different transcription sites that are more likely to accept one type of sequence over another, or a whole factory process going on inside, or it could have something we haven't even imagined. There's a LOT of room for variation in any case.
