Universe

Universe is (not 7 trillion Ly) at 600 Bly

*(some contents taken from an old wiki,* [1]*)*

A universe, by definition, is a system (Verse) corresponding to a continuous region of spacetime, and consisting of direct mappings from strongly enforced laws to physical objects.

The laws being strongly enforced, mean that they cannot be changed without direct modification access (for example, via the laws of a Multiverse).

They have a Nestation Index of 0 due to being a base of that index, are set within Multiverses, and some contain structures and life.

## Development Tier

Universes are "developed" to varying degrees, on two extreme ends (static voids, and post-Universal effects). Here is a list of development tiers:

## Our Universe

*This section is mainly a overview of this page on Wikipedia, so some details will be omitted.*

*Some bits of information in this section are not from the Wikipedia article, meaning that some parts are not fully real.*

Our universe is the biggest object that human civilizations are aware of, although we have theorized Multiverses and other verses to be what is beyond universes. It contains Galaxys, at least one planet with civilizations (Earth), and more.

### Formation

Our universe formed in extreme heat and density, and the forces of our universe also might have started out unified. This period is known as the "Planck Epoch".

As the universe cooled and expanded, forces started to form, then subatomic particles, then eventually proper atoms. After that, progressively bigger and bigger structures would form, leading to the eventual formation of our modern universe.

### Forces

The universe we are in has 4 fundamental forces, which are known as gravity, electromagnetism, and the strong/weak forces.

The force of gravity is based on curvature of spacetime, electromagnetism is based on the positive/negative charges of protons and electrons. The strong force is responsible for keeping quarks together, while the weak force is responsible for the decay of unstable atoms.

### Composition

Our universe is mainly composed of dark energy (energy responsible for spacial expansion of our universe), dark matter, and typical matter. Electromagnetic radiation and antimatter are also present, although in way smaller quantities.

### Observability

Due to the fact that electromagnetic radiation (light) has a finite speed (speed of light, which is 300,000 km/s), and the fact that the universe has a finite age (13.8 billion years), only the light of certain objects have reached the Earth. This means that some objects are "too far away" to be observed; their light has not reached the earth yet.

The information available about the universe implies that the diameter of the "observable universe" (the part of the universe observable by humans so far) is 93.2 billion light-years.

### Other information

The universe we are placed in is constantly expanding, and will be for a while. Eventually however, the universe will die out via various means.

One theory of how the universe will die out is the heat death, in which all energy would be equally distributed. Because our universe's laws aim to balance energy between objects, there is "nothing" for our universe to change, so it will stay static for a long time (estimated to be 1 trillion years) before transforming into a Post-Ultimaverse.
