LA Sunsets 🌞 are the stuff of legends. You can see amazing ones over the ocean from the beach or on a mountainside in Malibu. Towering rooftop skyscraper restaurant sunsets stretch-out over the half the sparkling city or you can sit atop Hollywood Hills and watch it cascade down over all the upscale real estate.

There's a reason the sunsets are incredible -- it not JUST the natural wonderment of it all -- but also the energy surrounding everything Los Angeles, Hollywood, California that makes the evening sky so magically intense!

Experience it for yourself is the BEST way -- pictures, videos are a second rate substitute. Be sure to come on out to LA, CAL and see some for yourself! 🏝

Week 2: Getting Intense(ive)

Howdy y'all, it's me Connor back after, quite frankly, an exhausting week of classes. When I learned I was going to be taking class here I thought I would be taking ✨Classes✨ but in reality I am going to the library most days. That being said I don't think I have ever been more interested in what I am learning than I am right now.

This is a picture of me and my dorm-mates walking to our first class together.

Intro to Japanese has been nothing but spectacular. Although the class is moving a bit slower I have chances everyday to practice what I learn so I am getting quite confident in my abilities. Also the teachers are so nice and helpful in class even though they do not speak almost any English.

In the afternoons we have Automotive Engineering class, now these are the tough ones. Having a 4 hour lecture every afternoon is not for the weak. What is entertaining though is the people the University bring in to special lectures. We have met employees from Nissan, Toyota, Mitsubishi and more. All of them gave given us amazing lectures on the future plans for these companies and what to expect if we ever end up working there. All of the lectures have been passionate to a point I have never experienced in the United States, everyone truly seems to love what they are doing and it makes the class so much more fun.

With about 5-6 hours of lecture a day I will at least concede the point that the amount of homework we have is light, often only a one page reflection on the information e learned, which is quite nice as I often find myself exploring in the afternoon/night with friends.

Another huge upside of this school is the cafeteria, the food is absolutely wonderful and dirt cheap:

Two of the lunches I've had. On the left a spicy miso ramen and I do not quite remember what the ride noodle bowl was called but it was equally delicious. Both of these cost me about $3 USD and they were amazing.

This first week we also had special tours of a number of different research labs here at Nagoya University.

These are two concept cars designed and created within the university. On the left you can see a small Toyota fitted with lidar and camera sensors, this is one of the universities forefront autonomously driven vehicles. On the right is a built from scratch "Slocal' (A slow locally driven vehicle which often gives verbal directions to the driver) vehicle which has the primary purpose of helping the elderly get around safely.

In addition to the research cars they have multiple highly technical driving simulators used for the research. These things are crazy big and so cool. I was even able to drive in one of them for a short while and the amount of modifications that are available via. software editing is ridiculous.

That was about it in terms of the technical knowledge and class stuff for this week so now we get to FOOD REVIEWS!!!!! <3

After being in Japan for over a week at this point I still had yet to have sushi so me and my roommates went and found this little hole in the wall place.

You can see me and my friends sitting at the bar on the left and the finished food spread on the right. We were the only ones in here for dinner which made sense as the sign outside only said すし which just translates to sushi (So still don't know the name of this place). We had an amazing time and the food was great and we even talked to the chef a bit in Japanese.

Around midweek I was craving something super spicy, and my girlfriend Olivia recommended me aa curry chain before I left called Coco Ichiban so we tried it out

This is the spread of each of our orders. Mine is in the bottom left (The one that is several shades darker than the others) I did not understand how the spice level system worked here and ordered a level 8. It turned out that meant it was about 24 times spicier than level 1. My spice cravings were definitely satisfied and then some. Still we had an amazing dinner and I do want to go back to try the level 10.

The next spot also came recommended from Olivia and it was a cream puff spot called Beard Papa.

This is a photo of all of their types of cream puffs. I got three different kinds: vanilla, peach, and green tea filling all with the original pastry. They were rich, decadent, and sweet; Everything you could want in a cream puff. (My favorite was the peach)

Lastly I did just a little bit of sightseeing towards the end of the week.

This is me at a Chunichi Dragons baseball game. Baseball is huge in Japan and this is the local Nagoya team. This night they won 1-0 against the Hiroshima Carp. The energy was super high the entire game, fans constantly cheering, music playing, it was so much fun. (I ended up buying a jersey because the starting pitcher did so well).

I have felt so much more comfortable in my surroundings this week and cannot wait to keep learning about and exploring this amazing country.

Until next time, さようなら, また 来週

Buracos Negros, Coerência Informacional e a Reconstrução da Seta do Tempo

Renato Ferreira da Silva 1º de junho de 2025

Resumo

Este artigo propõe uma reconstrução funcional da seta do tempo a partir da degradação informacional em campos escalares próximos ao horizonte de buracos negros. Baseando-se em fundamentos da relatividade geral, termodinâmica gravitacional e cosmologia observacional, integramos a análise clássica da dilatação temporal e do redshift gravitacional à formulação de um novo funcional de tempo T(t,r). Este funcional articula entropia local de coerência com a transição causal global descrita pelo parâmetro Φ(t), oferecendo um modelo emergente para o tempo como entidade informacional.

1. Introdução

A pergunta "o que é o tempo?" percorre a história da filosofia e da física. Na relatividade geral, o tempo é uma coordenada sensível à curvatura do espaço-tempo, o que o torna relativo à distribuição de energia e massa. Buracos negros, regiões de curvatura extrema, deformam o tempo de forma radical, aproximando-o de sua anulação aparente na perspectiva de um observador distante. Este trabalho parte de dois problemas clássicos da física gravitacional para construir um modelo mais geral: a reconstrução da seta do tempo a partir da degradação informacional gravitacional.

2. Fundamentos Físicos

2.1. Tempo na Relatividade Geral

ds2=−(1−2GMrc2)c2dt2+(1−2GMrc2)−1dr2+r2dΩ2

2.2. Termodinâmica Gravitacional

TH=ℏc38πGMkB,SBH=kBc3A4Gℏ

3. Problema 1: Dilatação Temporal

Para um observador em órbita estável: dτdt=1−3GMrc2⇒Δt=Δτ1−3/r

Próximo ao horizonte, r→3Rs+⇒Δt/Δτ→∞

4. Problema 2: Campo Escalar e Redshift

Equação de Klein-Gordon: □ϕ−μ2ϕ=0

Comportamento assintótico em coordenadas de Eddington-Finkelstein: ϕ(v,r)∼e−iωv(r−Rs)iα,α=2Rsωc

Esse termo revela degradação de fase, ou seja, perda de coerência informacional observável.

5. Cosmologia e Transição de Regime: O Parâmetro Φ(t)

Definido como: Φ(t)=ρm(t)+ρr(t)ρΛ

Quando Φ(t)→0, o universo torna-se dominado por energia escura, e a estrutura causal é diluída. É uma transição de fase informacional da cosmologia.

6. Formulação do Problema: Tempo como Função Informacional

Proponho o funcional: T(t,r)=(Slocal(r)SBH)⋅Φ(t)

Onde:

Slocal(r): entropia de von Neumann do campo ϕ

SBH: entropia gravitacional

Φ(t): peso cosmológico da causalidade

Esse funcional mede a grau de degradação da coerência temporal.

7. Resultados Esperados e Implicações

Uma nova definição funcional da seta do tempo

Integração entre física de buracos negros e cosmologia

Resposta funcional ao paradoxo da informação e à irreversibilidade

8. Conclusão

Buracos negros, antes vistos como paradoxos, são neste modelo laboratórios ontológicos do tempo. A degradação informacional local de campos em sua vizinhança simula o colapso causal em escala cosmológica. A função T(t,r)conecta essas escalas em uma medida objetiva da seta do tempo.

There's incredible fun to be had all across Los Angeles and Southern California.

Can YOU believe this is on the beach, ocean mist hitting you as you walk and stay active??? All nestled in the greatest city in the world!

That's LA - a special place like no other. There's a ton to do and see -- healthy vibes and positive pulsations. Book a TRIP and get out here! We're ready for YOU! Time to show you some HOLLYWOOD LOVE!
