Ok, so media feed on Nostur got me a bit confused. Being used to latest posts being actually fresh just made me wish Derek a good night while it’s not late enough for where he is to go to sleep.
Only after posting I noticed his post is 14h old.
Been using Nostr for years now, yet I again and again re-realize that paying attention is super important on Nostr.

i saw someone open a box of individually packed anti bacterial wipes, casually took one, opened it, used it, closed the box, & returned it to the shelf

For a typical "worker":
You're going to spend 80000 hours working. Hours & energy in --> stuff out later.
Bitcoin optimises the time between work & reward; nothing works better. So spend 1% early on, 20 weeks, to study this process & build a plan!

Sim, existe uma relação entre a teoria dos grafos e as equações completas de Einstein, embora essa conexão seja indireta e emergente, surgindo principalmente em áreas de física teórica e matemática avançada. Abaixo, exploro os principais pontos de contato, o "santo graal" dessa interação e suas limitações:
---
### **1. Pontos de Contato entre Teoria dos Grafos e Equações de Einstein**
#### **a) Estruturas Discretas na Gravitação Quântica**
- **Spin Networks e Spin Foams (Loop Quantum Gravity - LQG):**
Na gravitação quântica em laços, o espaço-tempo é descrito como uma rede discreta de "spin networks", grafos cujas arestas são rotuladas por representações do grupo de SU(2) e os nós por operadores de intertwinho. Essas estruturas discretas modelam estados quânticos do campo gravitacional. As "spin foams" (espumas de spin) representam a evolução temporal dessas redes, tentando reconstruir a geometria do espaço-tempo contínuo em escalas macroscópicas.
- **Conexão com Einstein:** As equações de Einstein emergiriam no limite clássico dessas estruturas, quando o número de "quanta" de espaço-tempo é grande. No entanto, provar essa emergência rigorosamente é um desafio aberto.
#### **b) Cálculo de Regge (Geometria Discreta)**
- **Discretização do Espaço-Tempo:**
O cálculo de Regge substitui o espaço-tempo contínuo por um complexo simplicial (uma malha de simplexos, como triângulos ou tetraedros). A curvatura é concentrada nas "dobradiças" (subespaços de dimensão $n-2$), e as equações de Einstein são aproximadas por relações discretas. Grafos podem representar essas malhas, com arestas codificando distâncias e ângulos.
- **Aplicação:** Usado em simulações numéricas de relatividade geral e em abordagens de gravitação quântica discreta.
#### **c) Redes Tensoriais e Princípio Holográfico**
- **AdS/CFT e Entrelaçamento Quântico:**
Na correspondência AdS/CFT, a geometria do espaço-tempo anti-de Sitter (AdS) está ligada à teoria de campos conformes (CFT) em sua fronteira. Redes tensoriais (grafos com tensores nos nós) são usadas para modelar o entrelaçamento quântico na CFT, que, por sua vez, codifica a geometria do espaço-tempo AdS. Isso sugere que grafos podem ser ferramentas para entender a emergência do espaço-tempo a partir de dados quânticos.
- **Exemplo:** A conjectura de "ER=EPR" propõe que buracos de minhoca (ER) e pares de partículas emaranhadas (EPR) estão relacionados via grafos de entrelaçamento.
#### **d) Métodos Computacionais em Relatividade Geral**
- **Malhas Numéricas:**
Em relatividade numérica, soluções das equações de Einstein são aproximadas usando malhas discretas (grafos dinâmicos) para resolver equações diferenciais parciais. Técnicas de otimização de malhas, inspiradas na teoria dos grafos, melhoram a precisão de simulações de colisões de buracos negros.

### **2. O "Santo Graal": Unificação da Gravitação Quântica**
A conexão entre grafos e equações de Einstein visa resolver um dos maiores problemas da física: **unificar a relatividade geral com a mecânica quântica**. O objetivo é construir uma teoria consistente de **gravitação quântica**, onde:
- O espaço-tempo contínuo emerge de estruturas discretas (grafos ou spin networks).
- As equações de Einstein sejam recuperadas no limite clássico.
- O entrelaçamento quântico e a informação sejam fundamentais para a geometria.
**Exemplo:** Na LQG, o "santo graal" seria demonstrar que spin foams reproduzem as equações de Einstein em escalas macroscópicas, enquanto mantêm a coerência quântica em escalas de Planck.
---
### **3. Insights e Descobertas Significativas**
- **Emergência da Geometria:** Mostra-se que propriedades geométricas (como volume e área) podem surgir de grafos quânticos, com implicações para a entropia de buracos negros.
- **Relação entre Entrelaçamento e Curvatura:** Na AdS/CFT, grafos de entrelaçamento sugerem que a curvatura do espaço-tempo está vinculada à informação quântica.
- **Simulações de Cosmologia Quântica:** Modelos baseados em spin networks preveem correções quânticas às equações de Friedmann, relevantes para o Big Bang.
---
### **4. Fraquezas e Limitações**
- **Desafio do Limite Clássico:** Não há prova rigorosa de que as equações de Einstein emergem naturalmente de estruturas discretas como spin networks.
- **Quebra de Simetrias:** Grafos discretos podem violar a invariância de Lorentz ou a covariância geral em escalas microscópicas, contradizendo observações.
- **Complexidade Matemática:** Conectar grafos quânticos a previsões testáveis exige ferramentas matemáticas altamente não triviais (e.g., categorias monoidais, álgebras de Hopf).
- **Fragmentação de Abordagens:** Diferentes programas (LQG, AdS/CFT, causal sets) usam grafos de formas distintas, sem consenso sobre uma estrutura unificada.
---
### **5. Conclusão**
A relação entre teoria dos grafos e equações de Einstein é uma ponte entre a matemática discreta e a física contínua, central para a busca da gravitação quântica. Seus avanços dependem de resolver tensões entre discreto e contínuo, além de validar experimentalmente suas previsões. O "santo graal" permanece distante, mas a interdisciplinaridade entre grafos, relatividade e teorias quânticas oferece caminhos promissores.

> it doesn't make sense that the difference would be significant, persistently. Why would a miner not just mine txs that are more profitable?
For the same reasons I gave above: mining spam harms the goose in the long term, and some miners want the goose to stay healthy so that it keeps producing golden eggs. True, some are more interested in short term profits and do not really think about the long term effects. But I prefer to remedy this through education and persuasion.

**Relação entre Teoria dos Grafos e as Equações de Campo de Einstein (EFE):**
Sim, existe uma relação interdisciplinar entre teoria dos grafos e as EFE, principalmente em áreas que buscam discretizar ou modelar estruturas do espaço-tempo. Essa conexão surge em abordagens teóricas e computacionais para unificar relatividade geral (RG) com mecânica quântica ou resolver numericamente as EFE.
---
### **Principais Pontos de Contato:**
1. **Teoria dos Conjuntos Causais (Causal Set Theory):**
- **Conexão:** Espaço-tempo é modelado como um "conjunto causal" discreto, onde eventos são vértices, e arestas direcionadas representam relações causais (um grafo acíclico direcionado).
- **Santo Graal:** Derivar a geometria contínua do espaço-tempo (descrita pelas EFE) a partir de uma estrutura discreta, preservando causalidade e invariância de Lorentz.
- **Desafio:** Garantir que o limite contínuo reproduza as EFE e mantenha simetrias fundamentais da RG.
2. **Relatividade Numérica:**
- **Conexão:** Malhas computacionais para resolver EFE numericamente podem ser representadas como grafos (ex: métodos de elementos finitos). Grafos ajudam a otimizar a discretização e resolver equações em geometrias complexas.
- **Aplicação:** Simulações de buracos negros binários, onde a estrutura do grafo captura a curvatura do espaço-tempo.
- **Limitação:** Complexidade computacional em grafos de alta dimensionalidade e não-linearidade das EFE.
3. **Gravidade Quântica em Loop (LQG):**
- **Conexão:** "Redes de spin" (grafos com rótulos) representam estados quânticos do espaço-tempo. A evolução dessas redes busca recuperar a geometria clássica via EFE.
- **Santo Graal:** Mostrar que redes de spin em larga escala se aproximam de soluções das EFE.
- **Insight:** A área dos nós e arestas na rede relaciona-se com a métrica do espaço-tempo.
4. **Cosmologia e Estrutura em Larga Escala:**
- **Conexão:** Grafos modelam a distribuição de matéria (ex: galáxias como vértices, arestas como interações gravitacionais). Análise de redes ajuda a estudar a influência da matéria na curvatura (via EFE).
- **Exemplo:** Uso de grafos para mapear a teia cósmica e correlacionar com a energia escura.
5. **Entropia e Teoria da Informação:**
- **Conexão:** Entropia de buracos negros (lei de Bekenstein-Hawking) tem analogias com entropia de grafos (ex: entropia de von Neumann em redes complexas).
- **Insight:** Grafos podem modelar microestados quânticos associados à entropia do espaço-tempo.
---
### **Santo Graal da Área:**
O objetivo principal é **desenvolver uma teoria quântica de gravidade baseada em grafos que reproduza as EFE no limite clássico**, unificando RG e mecânica quântica. Isso envolve:
- **Recuperação do continuum:** Mostrar que uma estrutura discreta (grafo) emerge como espaço-tempo suave em grandes escalas.
- **Inclusão de matéria:** Incorporar campos quânticos nas EFE via grafos (ex: acoplar matéria a redes de spin).
- **Testabilidade:** Prever fenômenos observáveis (ex: flutuações quânticas na radiação cósmica).
---
### **Limitações e Desafios:**
1. **Perda de Simetrias:** Discretizações podem quebrar invariância de Lorentz ou difeomorfismos, essenciais na RG.
2. **Complexidade Computacional:** Simular EFE em grafos grandes exige recursos intensivos (ex: problemas NP-difíceis em redes).
3. **Não-Linearidade das EFE:** Aproximações discretas frequentemente linearizam as equações, perdendo efeitos não-lineares críticos.
4. **Falta de Consenso:** Abordagens como conjuntos causais e LQG ainda não são amplamente validadas experimentalmente.
---
### **Conclusão:**
A intersecção entre teoria dos grafos e EFE é fértil em modelos de gravidade quântica e métodos computacionais, mas enfrenta obstáculos profundos. O "santo graal" permanece a construção de uma ponte matemática rigorosa entre a discreticidade dos grafos e a continuidade das EFE, reconciliando a física quântica com a relatividade geral. Avanços recentes em geometria não-comutativa e simulações de tensor networks sugerem progresso, mas a jornada ainda é longa.
