The smallest self-replicating organism is Mycoplasma genitalium (a parasitic bacterium). Their genome size is approximately 600,000 bases long and contains around 500 genes.
Thus, in order to create the first self-replicating system that is needed before evolution can begin, the "primordial soup" would need to first spontaneously create a chromosome with ~600,000 base pairs that contains the correct sequence for ~500 genes; plus some additional molecular machinery to transcribe and translate the very first copy of this genome.
For reference, there is not enough energy in the known universe to crack a 100 character password via brute force; let alone crack the correct sequence of 600,000 base pairs needed to create a self-replicating system.
Thus, life cannot have been created by a "primordial soup" and life cannot have been created by evolution.

What can we expect from him on subjects related to math and science?
First there must be an established belief system. This is usually a cursory religion to serve as the foundation of a new belief system. This may not just be a continuance of the current faith, as in the case of Christianity, Mormonism and Islam, but may be a blasphemy of the foundation as is the case of Satanism and Scientology. This establishment may often find itself in a situation in which the doctrines and their reasonableness are challenged by changing times or new ideas.
Second there must be a prophet of a new faith who is sometimes a knowing imposter, others a deluded and/or disturbed individual. The prophet promotes themselves as delivering upon the prophecies established in the religion and also that their current prophecies are more perfect and/or final revelations.
Third is the bridge between the two. The believers must have a feeling of unfulfillment and the prophet must have skills in outreach. Engagement with an audience and a knack for both social leadership and storytelling are vital to kindle the spark of a new ideology. I’m sure that psychedelics also have assisted religion in both inspiration and credulity among leaders and followers alike.

I just watched a video trying to explain entropy ("I wish I was taught Entropy this way!" by "FloatHeadPhysiscs").
I swear I must have a smooth brain or something because I feel the "macro-state"/"micro-state" definition feels a bit wrong and really arbitrary.
As far as I can tell a micro-state with few configurations is low entropy and a micro-state with many configurations is high entropy. Here is where I feel something is weird, I also saw another video talking about entropy where you they show a beaker filled with dice ("The Mysterious Entropic Force" by "The Action Lab"), I don't really care about the video but I found the beaker filled with dice interesting in relationship to the "macro-state"/"micro-state" definition of entropy. Considering that a high entropy micro-state consists of a state that has many possible configurations, a beaker of dice tends to remove many of this possible configurations even though there are other micro-states with many more configurations.
Here are some points that are in my head:
- I'm maybe missing something.
- Maybe then I have to be a lot more specific in the definition of the system.
- I feel that pass some point of precision of definition it feels that I'm just choosing a scenario biased towards an specific conception of entropy.
Here is the points I think could better define the dice beaker scenario:
- Consider gravity as part of the system
- Evaluate entropy on static states. Maybe a fixed moment in time, this way shaking is irrelevant (I would preferred of shaking the beaker was not part of the system).
- When evaluating, the evaluated elements or characteristics of the configuration of the states have to be the same.

Why did we assume that physics is the same everywhere and build all our theories on that assumption?
For example, redshift can be easily explained by variable physics, without resorting to the nonsense of dark energy, which supposedly makes up 70% of the universe and seems to possess magical properties.
Apparently, proposing something that simple, something that doesn’t break our current understanding of the local world, but does explain many observations from distant parts of the universe, is worse than inventing magical undetectable stuff.
>P2) We can create a number different from all numbers in the list
>C) There is a contradiction, so P1 is false.
Does anyone see the problem here? It could be premise 2 that is false. For if every number is indeed in the list, then the diagonal construction is simply impossible.
>But how can that be? The construction seems intuitive.
Ignoring the fact that the construction requires the completion of an infinite process… we can see a specific case where the construction is flawed.
Consider all expressions that define a real number. We can map the naturals to the real numbers produced by those expressions, in increasing order of the expression length. Problem: does the diagonal number have an expression that defines it? If it does, then it’s already in the list at a specific section of the list on account of its length, and we see the contradiction: the diagonal number must be defined to be different than itself, so the construction is simply invalid. But what if the diagonal number doesn’t have an expression that defines it? Then it wouldn’t be in the list because it’s not a number at all, and we can’t refer to it since it can’t be defined.
One might assume that undefinable numbers are simply a reality and can save the diagonal argument, but it has never been proven, and it cannot be proven, that such numbers exist, because they can’t be referred to without defining them! It is in no way guaranteed that there exists some arbitrary infinite string of digits for which there exists no finite definition for it. But because the diagonal argument supposedly shows that the reals are uncountable, it’s therefore believed that undefinable numbers must exist. But you must first that undefinable numbers exist in order for the proof to work, because it’s well known that the definable numbers are countable.
It is a well known fact that for 99,9% of existence of human race, humans naturally had a lot of parisites, and our evolution and nature wasn't even considering that we may not have these parasites. Parasites are as natural to us, as bacterias. That's why a lot of us have some sort of allergy, but people with tapeworm don't have it, we are not supposed to not have tapeworms (especially people from poor backround, but I will come back to it later)!
This revolutionary theory totally explains why masses activly vote for anti-freedom candidates in elections. Policians are leeching on tax payer dollars, often giving nothing in return or even straight out poisoing it's feeders (see chemtrails), but not killing them (usually)!
Being oppresed, having worms, is a natural state of human, especially of humans coming from lower caste, historically speaking these castes were more prone to parasites! That's why aristocrats of the soul and body are not tolerant to mainstream politics, (too much parasites for evolutionarly not accustomed aristocrat chuddy!), instead they often chose libertarian type of parties.
But well, even prehistoric humans probably knew that parasites are bad, right? Yes, people want to fight with parasites, that's why literally everyone wishes to fight with oppression, but none wants a total death of all parasites - actually the contrary is true. It may sound paradoxical, but the truth is that people fight against oppression but they really need it!
State oppression is natural substitue for parasites, in parasite free society.
All the problems on Earth? pfffft, we can't wait a hundred million years to solve them, we must leave NOW and transport human fleshbags that require a breathable atmosphere and food millions of miles away to Mars! It's the only solution.
The supergenius greatest intelligence of all time has spoken, and we must listen! Just ignore that he already promised Starship would be landing on Mars in 2024 and it's now 2025 and it still hasn't been able to make low earth orbit, just ignore that! Any day now Starship in its glorious and definitely well engineered and thought out design will be transporting millions of Humans directly to Mars to prevent humans from going extinct on Earth! No, once the humans get to Mars, they can't breathe the air, it's colder outside than Antarctica, they can't grow crops in the soil nor can they easily access water or do anything outside of an environmentally sealed habitat, but certainly this is the place for humanity to survive and thrive, because one day the sun is going to be too hot and bright to live on Earth, and even though Mars will also be feeling that same heat and light increase it has to be the only other solution!

I have seen anons say that one day women will be replace with robo wife's, but It is far less feasible to replace women than it is to replace men. If we were to replace one of the genders it would be the male.
Each one of them is supposed to lower anxiety. They also lower testosterone. One of the side effects of low testosterone is increased anxiety and unstable mood.
All these drugs have extremely intense withdrawals that take months to ween off of, and they can all permanently lower libido. Going off of them cold turkey can lead to bouts of anxiety. All I started off with was a fear of heights.
People say, what's the alternative? It's just the only option science has.
But that is false. All of the entire world's entire psychiatric science, a global industry of $560 billion, is as fabricated as Kim Jong Un's physician's report that he is always in perfect health.
There was a 50 year ban on psychadelic research while this addictive, testosterone, dick destroying industry was put into place.
During that time, Alexander Shulgin, living underground, in a cave, with a box of scraps, developed dozens of anti-depressant and anti-anxiety drugs, with effects which last months from a single dose, with zero addiction potential, which do not lower testosterone, which do not cause bouts of anxiety, and which do not permanently lower libido.

>Protocol
It's a two step process.
Step1:
500mg Curcumin
500mg or so Tributryn
Take about a dropper full of B12.
Wait an hour.
Then, think of this as a balanced dose to start the reaction.
Step 2:
300mg Liposomal Apigenin
Another 500mg of Tributryn
About 500mg of either NAD or some combo of NAD and NMN.
Repeat step 2, 2-4+ times a day.
One week on one week off to avoid T cells exhaustion.
Ultimately this is your immune system first reprogramming itself and then going out to the rest of you. The T cells are able to identify cell wall markers where issues are the most severe and those will need to be targeted first before any specific issue.
Give it a little wiggle room if you don't need as much NAD or Tributryn. NAC is a good add in as well while doing this if you have a history of smoking or lung problems.
- The universe doesn't have a beginning or an end in a traditional sense. Instead, it goes through endless cycles (aeons), each starting with a "big bang" and ending in a slow, infinite expansion.
- These cycles are linked via conformal transformations, allowing the "end" of one to become the "start" of the next.
- This model challenges the classic view of a singular beginning (like the Big Bang) and offers a potential explanation for certain cosmological observations.
- Penrose has proposed that certain observed anomalies in the cosmic microwave background (CMB)—specifically ring-like patterns—may be signatures from events in previous aeons, such as collisions of supermassive black holes or other phenomena crossing the conformal boundary.
Nowhere else in the universe does this happen.

Sam Altman once said OpenAI and Microsoft had the “best partnership in tech.” Now, their Silicon Valley marriage is on the rocks.
Microsoft turbocharged the AI startup’s growth over the past six years with billions of dollars in funding, helping OpenAI’s ChatGPT accumulate more than 500 million weekly users. OpenAI powered cutting-edge generative AI tools for the technology giant, helping its share price triple.
That relationship has become strained. The CEOs are increasingly at odds over the computing power Microsoft provides to OpenAI, the access the startup gives the technology giant to its models and whether the Altman-led company’s AI systems will soon achieve humanlike intelligence, according to people familiar with their relationship. Microsoft CEO Satya Nadella has also made it a priority to beef up sales and usage of ChatGPT rival Copilot, and last year hired a rival of Altman’s who launched a secret effort to build models for Microsoft that would reduce its dependence on OpenAI.
While they are preparing their companies for independent futures, both still wield tremendous power over one another at a critical moment in the global AI race.

This is pretty much divination.
That isn't to demean math or exalt traditional divination or woo woo, it's to say that math is just a correct form of divination, or more accurately, physical prediction.
Now there could be an ontological argument about how true this is, but as far as how mathematics fits into the study of culture and religion, would calling math a form of divination be correct?
>No?
Then get the fuck off my board
A sycophantic model will often take the path of least resistance: agreeing with a user’s incorrect or misleading statement. It’s computationally and conversationally “easier” than providing a nuanced, well-supported correction.

A new DARPA project called expMath "aims to jumpstart math innovation with the help of AI," writes The Register. America's "Defense Advanced Research Projects Agency" believes mathematics isn't advancing fast enough, according to their article...
So to accelerate — or "exponentiate" — the rate of mathematical research, DARPA this week held a Proposers Day event to engage with the technical community in the hope that attendees will prepare proposals to submit once the actual Broad Agency Announcement solicitation goes out...
[T]he problem is that AI just isn't very smart. It can do high school-level math but not high-level math. [One slide from DARPA program manager Patrick Shafto noted that OpenAI o1 "continues to abjectly fail at basic math despite claims of reasoning capabilities."] Nonetheless, expMath's goal is to make AI models capable of:
- auto decomposition — automatically decompose natural language statements into reusable natural language lemmas (a proven statement used to prove other statements); and
auto(in)formalization — translate the natural language lemma into a formal proof and then translate the proof back to natural language.

An obscure paper dropped last week from a Kazakh institute nobody's heard of, claiming to have created a working prototype of a gravity lens—not using mass, but frequency-tuned neutrino interference. Sounds like BS? That’s what I thought until I saw the raw data dump and schematics. It’s eerily consistent with unverified DARPA patents from 2003 and mimics the gravitational anomalies observed near the Moon’s far side.
Before mods nuke this for “pseudoscience,” understand:
- They replicated gravitational time dilation in a lab setting.
- No exotic matter. No wormholes. Just wave superposition.
- An internal whistleblower from JAXA posted an identical experimental setup on a dead Usenet node 3 years ago. It got zero attention.
Why now? Why buried? Who benefits?
If this holds, Newton, Einstein, and quantum loop all get metaphorically curb-stomped.
