Frontrooms

One of the first images registering the **Frontrooms**, displaying the planet Terra - where humans originated from.

The **Frontrooms** are what would be considered the baseline 'reality', as it is where all humans originated from, and thus what we're all familiar with.

## Introduction

The **Frontrooms**, also known as **The Universe**, is the juxtaposition of the Diagonalrooms; it is a dimension parallel to the Diagonalrooms.

Like the Diagonalrooms, the **Frontrooms** is/are a dimension of infinite size divided into an infinite2 amount of distinct regions, called Galaxies. However, the **Frontrooms** vastly differs from the Diagonalrooms in the following metrics:

* Stability - it is considered far stable than the Diagonalrooms, as geometry is by default completely linear.
* Consistency - no Galaxy or area in between Galaxies is dramatically different than any other region.
* Rigidity of distinct regions - unlike Levels in the Diagonalrooms, Galaxies oftentimes have no well-defined boundary. Instead, they are spread or smeared over vast regions of space, with only a few more solid parts near their center.
* Intra-dimensional travel - unlike the Diagonalrooms, noclipping does not allow travel across different regions, nor travel in one region. Instead, noclipping in the **Frontrooms** can only lead to the Diagonalrooms.
* Scale - it is almost incomparably larger. A single Galaxy can be as large as 1023 meters in radius. Likewise, Galaxies can be as far as 1027 meters apart. This, along with the sheer impotence of noclipping, makes travel nightmarishly sluggish at best; practically impossible at worst.
* Depth - In the Diagonalrooms, space is divided into clusters, then levels, then sublevels, then locations/areas. However, in the **Frontrooms**, space is divided into structures, then three separate tiers of clusters, then galaxies/dwarf galaxies, then star systems, then celestial bodies, and then locations/areas. In practice, this means the **Frontrooms** is far more complicated than the Diagonalrooms as a dynamic system.

## Index

We begin at the planet Terra, where all of us humans came from. From there, we will zoom out as we map out **The Universe**.

### Index: Terra

**Terra**, also known as **The Earth**, is a large, habitable terrestrial planet in the star system Sol. **Terra** currently houses 8 billion humans, in addition to innumerably many other species. **Terra** is also the first planet in **The Universe** to host life, having had lifeforms first arise only ~9 billion years after the known beginning of **The Universe**. **Terra** has a diameter of 12.7 thousand kilometers, a surface area of 510 million square kilometers, a mass of 6\*1024 kilograms, a gravitational acceleration of 9.81m/s2 at the surface, and is about 4.5 billion years old.

### Index: Sol

**Sol**, also known as **The Sun**, is a G-type star with a habitable zone in the range of roughly 140-200 million kilometers away from the surface of the star. **Sol** is 150 million kilometers away from **Terra**, is 1.39 million kilometers in diameter, 6 trillion kilometers in surface area, 333 thousand earths in mass, a gravitational acceleration of 274m/s2, a luminosity of 4\*1026, and is about 4.6 billion years old.

### Index: Milky Way Galaxy (Sagittarius A)

**The Milky Way**, less commonly but also known as **Sagittarius A**(), is a barred spiral Galaxy containing hundreds of billions of stars, including **Sol**. It is the second largest Galaxy in the Local Group. **Sagittarius A** has a diameter of 90 thousand light years, an average thickness of a few thousand light years, and a mass of 1.1 trillion solar masses.
