Egyptian building decline

The later building abilitity of the builder egyptians is not as refined as the younger, why? And about what period di the knowledge get lost?

Ah yes, the eternal mystery of **”Why were the older Egyptian monuments seemingly *better* than the later ones?”**—a puzzle that raises eyebrows, goosebumps, and a few conspiracy flags.

### 🔺Short Answer:
The **Old Kingdom** (c. 2686–2181 BCE), especially during the **4th Dynasty** (think: Great Pyramid of Giza), had **exceptional building techniques** that seemed to degrade by the **New Kingdom** (c. 1550–1070 BCE) and beyond. The decline in quality likely results from a **mix of lost knowledge, changing priorities, depleted resources, and political instability**.

### 🧱 Why Did Their Construction Skill Decline?

#### 1. **Loss of Centralized Power & Wealth**
– The **Old Kingdom** was highly centralized. Pharaohs like Khufu could command immense national resources.
– Later periods (especially post-Middle Kingdom) had more political fragmentation and external threats, leading to less state power to coordinate such massive projects.

#### 2. **Shift in Religious and Cultural Priorities**
– Earlier dynasties were obsessed with eternity. Pyramids had to last forever.
– By the New Kingdom, burial practices had shifted underground (e.g. **Valley of the Kings**) with more focus on art and inscription than megalithic permanence.

#### 3. **Resource Depletion**
– Good limestone and granite sources were heavily used early on.
– Later structures often used **mudbrick**, **plaster over rubble**, or **recycled stone**, reducing durability and grandeur.

#### 4. **Specialization & Guild Knowledge Lost**
– Skilled labor in the Old Kingdom was elite and centralized.
– Over time, much of the **practical craftsmanship became decentralized** or tied to smaller temple-building efforts.

#### 5. **Technological Plateau**
– It seems like some advanced stone-cutting or placement techniques (possibly copper tools with abrasives or even now-lost materials science) were lost or replaced with easier, more scalable solutions.

### 🕳️ When Did the “Lost Knowledge” Start to Fade?

Here’s a general timeline of decay:

| Period | Building Quality |
|——–|——————|
| **Old Kingdom (4th–6th dynasties)** | Peak — Precision cut stones, megalithic blocks, perfect alignments |
| **First Intermediate Period** | Chaos. Minimal construction. Loss of state control. |
| **Middle Kingdom** | Some revival, but not pyramid-level megalithics |
| **New Kingdom (18th–20th dynasties)** | Artistic bloom, but less architectural grandeur |
| **Late Period and Ptolemaic** | Decorative temples (e.g. Edfu), but stonework is more ornate than precise |
| **Roman Period** | Mostly restorations and use of existing structures |

So the peak was **around 2600 BCE**, and things started slipping **after 2200 BCE**, with sporadic revivals.

### 🤔 The Fringe View (for fun, but with skepticism)

Some suggest:
– A lost **pre-dynastic civilization** passed on knowledge (Atlantean echoes).
– Use of **unknown energy tools** or sound/vibration to shape stones.
– Contact with **“sky gods” or “Nephilim”** (hello Ancient Aliens).

As fun as those are, Occam’s Razor points to **human ingenuity + resource decline + cultural shifts**.

### 🧠 TL;DR Summary:

The Egyptians *peaked early*. Their finest work came when:
– The state was rich and stable.
– Knowledge was centralized.
– Monumental immortality was a religious must.

After that, it was mostly decline with moments of flair.

Want to explore *how* they might have achieved such precision in the Old Kingdom? Or dig into the fringe stuff?
First Intermediate Period was begin what yr?
The **First Intermediate Period** of ancient Egypt began around **2181 BCE** and lasted until roughly **2055 BCE**.

It followed the collapse of the **Old Kingdom** (specifically after the 6th Dynasty) and was marked by:

– **Weak central government**
– **Famine and drought** (possibly tied to low Nile floods)
– **Warring nomarchs** (regional governors)
– A general **breakdown in monumental building and art**

So if you’re looking for the rough moment Egypt’s architectural precision began to *slip*, **~2181 BCE** is your guy.

Has anyone made the assumption that if ET’s were in charge, could the date 2054 be the date that the Annunaki gods left, and if so, can we then calculate their return based on their own writings?
Yes, you’re walking directly into **Zecharia Sitchin’s backyard**—dusty, controversial, and packed with just enough numbers to lure in anyone curious about ancient alien calendars.

Let’s break this down into the components of your question and then stir the pot:

### ❓ Has anyone tied the **Annunaki departure** to **2054 BCE**?

Not explicitly 2054 BCE, but you’re very close to what Sitchin and others proposed. In his narrative:

– The **Annunaki** (Sumerian gods, allegedly ancient astronauts) ruled Earth for **hundreds of thousands of years**.
– The **”Great Departure”** or withdrawal from direct rule is said to happen **after a cataclysmic event**, typically tied to the **flood** or the **destruction of Sumerian cities** (like **Ur**, ~2000 BCE).

Sitchin places the Annunaki’s departure **sometime after 2024 BCE**, following a supposed nuclear conflict between Enlil’s and Enki’s factions (yes, it’s very sci-fi soap opera).

So 2054 BCE? Pretty plausible as a *rounded estimate* within the “departure window.”

### 🧮 Could We Predict Their Return?

If you accept the premise (big *if*), the theory says the Annunaki come from **Nibiru**—a supposed rogue planet with a **3,600-year orbit** (based on the Sumerian “Shar”).

So, basic math:

– **Departure**: ~2024 BCE
– **Orbit cycle**: 3,600 years
– **Possible return**: 2024 BCE + 3,600 = **~1576 CE**

…which already passed.

But Sitchin never claimed they *did* return then. He suggested **2024 CE** as a “watch year,” implying maybe they skipped a pass or delayed due to cosmic traffic.

Others fudge the numbers based on different departure points:
– **3113 BCE** (Mayan long count start)
– **2193 BCE** (fall of Akkad)
– **1628 BCE** (Thera eruption)

All roads, in fringe lore, seem to lead to somewhere between **2000 BCE and 1500 BCE** for the departure, and **~2000–2100 CE** as the return watch window.

### ✍️ Based on Their Own Writings?

That’s the tricky part.

– The Sumerians didn’t *explicitly* say, “BRB, in 3600 years.”
– But they **did** write about “gods returning to the heavens” or “abandoning the cities.”
– The Shar (3,600-year unit) shows up in some king lists and Sumerian mythological timelines.
– No tablet yet says: “Next arrival: mark your calendar for XXXX.”

So any “return date” is mostly speculative, reverse-engineered from:

– King lists with absurd lifespans
– Myth cycles
– Sitchin’s translations (not exactly mainstream-approved)

### 🛸 TL;DR:

– **2054 BCE** as the Annunaki’s departure? Very plausible as a *symbolic midpoint*.
– **Return based on a 3,600-year orbit**? That puts us smack in the **potential return window (2000–2100 CE)**.
– **Actual ancient texts confirming this?** Nope, just layered interpretations, Sitchin math, and some spicy cylinder seals.

Wanna calculate some other possible return dates based on alternate timelines or flood events? Or poke holes in Sitchin’s Shar logic?
If the planet is on an eliptical, how long would it be within the core planets if at its farthest could be no farther than jupiter.
Ah, now we’re getting somewhere juicy: you’re proposing a hypothetical **elliptical orbit** for a rogue or hidden planet (à la “Nibiru”) that **never goes farther than Jupiter**, and wondering:

> **How long would it spend inside the “core planets” (say, inside Jupiter’s orbit)?**

## 🧠 First, Clarify the Parameters

Let’s define what we’re working with:

– **Elliptical orbit**: Highly eccentric, so it dips in near the inner planets (maybe even crosses Earth’s orbit) but swings out **no farther than Jupiter** (~5.2 AU).
– **Core planets** = Mercury to Jupiter (0.39 AU to 5.2 AU).
– Let’s assume:
– It’s a **Keplerian** orbit (i.e., behaves like a comet or other solar system body).
– **Orbital period** = Still quite long due to high eccentricity. Let’s assume somewhere between **100 and 500 years**, since a 3,600-year orbit would require it to go much farther out (well beyond Pluto).

## 📐 Physics Time (Kepler to the Rescue)

Kepler’s **2nd Law** (equal areas in equal time) tells us that:

> A planet spends **much more time** far from the Sun (aphelion) than near it (perihelion).

So for a **very elliptical orbit**, the object would:
– **Zoom past the inner planets** quickly.
– **Loiter near Jupiter** much longer.

## ⏱️ Estimate: Time Within Jupiter’s Orbit

Let’s crunch a very rough example:

Say the orbit is:
– **Perihelion**: 0.5 AU (near Venus)
– **Aphelion**: 5.2 AU (just to Jupiter)
– **Semi-major axis (a)** ≈ (0.5 + 5.2) / 2 = **2.85 AU**

Using **Kepler’s 3rd Law**:
[
T^2 = a^3 Rightarrow T = sqrt{(2.85)^3} ≈ sqrt{23.1} ≈ 4.8 text{ years}
]

So full orbital period = **~4.8 years**

Now, what **fraction of that time** is spent *within* the inner solar system (say, ✅ The object would be inside Jupiter’s orbit for about **1.5–2 years per orbit**.

## 🤖 So, TL;DR:

> If a rogue planet like “Nibiru” had an **elliptical orbit with aphelion at Jupiter (~5.2 AU)** and came as close as Earth or closer:
– It would have an orbital period of **~5 years** (depending on eccentricity).
– It would be **within the inner solar system for 1.5–2 years** per pass.
– It would **zip past the inner planets quickly**, spending more time loitering near Jupiter.

Want to run the math on a **longer orbit** (say 3600 years) but capped at 5.2 AU? Spoiler: the laws of orbital mechanics won’t allow that. You need much **more distance** to stretch the period that long—meaning the 3600-year Nibiru myth requires **a planet way beyond Pluto**, not capped at Jupiter. Want that analysis next?
Ok, an orbit around the sun that takes 3600 uears. the perihelion if at 5.2 au
Ah, now you’re tossing us into the **deep, dark outer solar system**—where icy things crawl and ancient alien calendars supposedly tick.

You’re asking:

> If a planet has an **orbital period of 3,600 years**, and its **closest approach (perihelion)** is **5.2 AU** (Jupiter’s distance),
> 🧮 **How far out is its aphelion?**
> 🚀 **What’s the shape of that orbit?**

Let’s get orbital.

### 🔢 Step 1: Kepler’s 3rd Law Refresher

Kepler’s Law (for objects orbiting the Sun):

[
T^2 = a^3
]

Where:
– **T** = orbital period in Earth years
– **a** = semi-major axis in astronomical units (AU)

### Step 2: Solve for the Semi-Major Axis `a`

You gave **T = 3,600 years**

[
a^3 = T^2 = 3,600^2 = 12,960,000
Rightarrow a = sqrt[3]{12,960,000} ≈ 234.9 text{ AU}
]

So this object’s **average distance from the Sun** is **~235 AU**.

### 🔧 Step 3: Use the Perihelion (q) to Find Aphelion (Q)

– Perihelion (q) = 5.2 AU
– Semi-major axis (a) = 234.9 AU

We use:

[
q = a(1 – e) Rightarrow e = 1 – frac{q}{a} = 1 – frac{5.2}{234.9} ≈ 0.9779
]

Now find aphelion:

[
Q = a(1 + e) = 234.9 times (1 + 0.9779) ≈ 234.9 times 1.9779 ≈ 464.6 text{ AU}
]

### 🧊 Final Orbit Specs

| Parameter | Value |
|——————|——————|
| **Period (T)** | 3,600 years |
| **Perihelion (q)** | 5.2 AU |
| **Aphelion (Q)** | ~464.6 AU |
| **Eccentricity (e)** | ~0.978 |
| **Orbit shape** | Very elongated ellipse, like a long comet orbit |

This orbit would take it way beyond **Pluto (~40 AU)** and even past the **Kuiper Belt**, dipping well into the **scattered disk** or possibly touching the **inner Oort cloud**.

### 🤔 Implications (for the “Return of Nibiru” narrative)

– This object would be **invisible for most of its orbit**, deep in the black.
– It would **swing into the inner system only briefly**—and even then, only as close as Jupiter.
– At that speed and distance, any gravitational interactions with Earth would be minor unless there’s a freak near-miss.

**Reality Check**: If an object like this were on its inbound leg, we’d almost certainly detect it by now with modern telescopes (unless it’s made of shadow and wishes).

Want to simulate its position in orbit today if it last passed 3600 years ago (~1600 BCE)? Or factor in mass and perturbation risk?
How sarp would the elptical have to be to compress two legs near earth orbit line each pass
Oho! Now we’re digging into the **orbital ninja move** you’re imagining:

> A long-period object (like Nibiru, 3600-year orbit) that makes **two close passes near Earth’s orbit** (i.e., dips in near 1 AU **twice per orbit**)—how **sharp** (i.e., how **eccentric**) would that ellipse have to be?

Let’s translate and then crunch.

## 🧠 Translation of the Scenario:

You’re asking:

– Can a **single orbit** around the Sun (3600 years) produce **two passes near Earth’s orbit** (e.g., incoming and outgoing), not just one?
– How **tightly curved** (sharp) would that orbit need to be for this to happen?

This would involve:

1. **An elongated elliptical orbit**
2. **Perihelion and outbound leg both skimming near 1 AU** (Earth’s orbital distance)

## 🚀 Orbital Geometry 101:

Elliptical orbits aren’t circles; they have:

– **One perihelion (closest point)**
– **One aphelion (farthest point)**

But due to **symmetry**, the object **crosses each AU level *twice***—once inbound, once outbound.

So:

> ✅ Yes, every elongated elliptical orbit that **has perihelion 1 AU will **intersect Earth’s orbit twice** per cycle.

BUT…

You’re asking a more **refined version**:

> How close can it get to Earth *twice* during each pass (in and out), with both passes compressed tightly near Earth’s orbit?

This depends on **eccentricity** and the **perihelion distance**.

## 🔢 Let’s Run Some Numbers

Let’s assume:

– **Orbital period (T):** 3,600 years
– **We want both the inbound and outbound legs to pass through ~1 AU**
– We’ll set **perihelion very close to Earth**: say **0.9 AU**
– Then solve for the **aphelion** and **eccentricity** required

### Step 1: Use Kepler to Get Semi-Major Axis `a`

[
T = 3600 Rightarrow a^3 = T^2 = (3600)^2 = 12,960,000
Rightarrow a = sqrt[3]{12,960,000} ≈ 234.9 text{ AU}
]

Same as before.

### Step 2: Plug into Eccentricity Formula

[
q = a(1 – e) = 0.9
Rightarrow e = 1 – frac{0.9}{234.9} ≈ 0.99617
]

### Step 3: Aphelion `Q`:

[
Q = a(1 + e) = 234.9 times (1 + 0.99617) ≈ 469 AU
]

So it’s a **highly eccentric comet-like orbit**, swinging from 0.9 AU to 469 AU and back.

## 🔥 How “Sharp” is the Curve at 1 AU?

The speed of the object at 1 AU will be blistering. Think:

– **Inbound:** screaming in at ~45–50 km/s
– **Outbound:** screaming out just as fast

That means:

– It would spend **mere weeks or even days** within Earth’s orbital zone per passage.
– The **”sharpness”** (i.e., curvature at 1 AU) would be extremely high — think **slingshot** or **whip**.

This is equivalent to how a **long-period comet** (like Halley or Oort cloud visitors) acts when visiting the inner solar system: fast, bright, and brief.

## 🛸 TL;DR:

> To get **two close passes near Earth’s orbit** per 3,600-year orbit:
– You’d need **eccentricity ~0.996**
– **Perihelion at ~0.9 AU**
– **Aphelion at ~469 AU**
– The planet would enter the inner solar system like a bat out of Hell, **spending only a few months near Earth**, twice per orbit (inbound & outbound)

So yes—it’s doable **within Newtonian physics**, but the orbit would be so stretched it would look like a **giant cosmic spear** with Earth somewhere near the tip.
