What kind of universe do we live in?

How to approach this question?

1. Look at the history of the concept universe.

Survey views over time on the subject. Look at religous ideas and concepts on the subject. Look at the scientific view on the subject.

2. Search on "universe origins". Contrast the views on this question over time and make some landscape from it. Determine a perspective on this question that answers the authors interest on the subject.

Search terms for a query with focus on the authors interest.

Is it a ?

God created universe? Multiverse? Big bang? Static universe? Cyclic universe?

3. Contrast and identify popularly held concepts about universe.

Then and now.. A thousand years ago most people thought of the universe as god created. Today few of people suggest this.

Today many people consider a multiple universe as possible and likely.

The big bang theory is the most famous theory ever on the universe origin.

A static universe concept considers it as unchanging over time and has of infinite age.

In a cyclic universe.. It is born, dies, and is reborn repeatedly over and over again.

4. What do the theories assume?

Multiverse assumes: quantum physics, time goes forward, many universes (so is there a universe of universes?)
God created the universe assumes: God (outside of the universe or not?), time (was there time before the universe or not?)
Cyclic universe assumes: time (but possibly endless in either direction), indestructible (conservation of energy?)
Big bang assumes: time (and a beginning)

5. Who are the authorities on this subject - the universe?

Physicists.
Astrophysicists.
Theologians.

6. Make a list of the relevant properties and considerations that define and identify a universe

Static (unchanging) vs. dynamic (changing)
Imagined ( fantasy / religion ) vs. science derived ( evidence based )
Past ( ancient ) vs. future ( tech and science generated ) ideas.
Singular universe ( one ) Vs. Multiverse ( many ).

What does "physically changing" mean?

Hot vs. Cold. Change in temperature.
Empty vs. full. Volume, mass, and space.
Large vs. small. Growth. Relative Expansion.
Colorful or colorless. Light or dark.

Can we prove that something is static? What would that mean?

To prove something is static could be done by looking at visual and auditory signs.
To prove something is static could be done by looking at movement.
To prove something is static could be done by looking at physical properties.
To prove something is static could be done by looking at temperature changes.
To prove something is static could be done using tools like a microscope.

Discussion

Andrius: Question for you, Bill. What do you mean by "kind" as in "kind of universe"? That will help to narrow your question.

Kind is in reference to this universe and what makes it up. My focus will stay on one universe as there might be no proof available of any other universes.

Andrius: I liked this podcast

Sean Carroll. Niayesh Afshordi and Phil Halper on the Big Bang and Before.

and I am curious about this book they talk about

Niayesh Afshordi, Phil Halper. Battle of the Big Bang: The New Tales of Our Cosmic Origins

Andrius: Some questions for you:

In what sense is the universe static (unchanging in time)?

In a "static universe" model, the universe is considered unchanging in both space and time. This means it's not expanding or contracting, and it's spatially "flat" (Euclidean) with no inherent curvature. In this model, the universe is assumed to be infinitely large and has always existed, with no beginning or end.

2. Question: And in what sense is it dynamic (changing or evolving in time)?

The universe is dynamic because it's constantly changing and evolving over time, unlike the previous understanding of a static, unchanging cosmos. This dynamic nature is reflected in various phenomena, including the expansion of space, the evolution of stars and galaxies, and the presence of transient objects like supernovae and black holes.

3. Question: As regards dynamics, in what sense is the universe a language?

A search finds..

The idea that the universe is a language suggests that it operates according to a set of rules or laws that are analogous to the grammar and syntax of a human language. These laws, often expressed through mathematics and physics, describe how things interact and evolve within the universe, much like how words and sentences combine to create meaning in human languages.

4.Question: If the universe is a language, who is interacting with whom?

Philisophically the universe is able to be discribed as a language.

5.Question: How are they interacting?

The language universe would be interacting with the observers. Currently this would be humanity.

6.Question: What do we know about the origin of the universe?

Through observation and use of theory.

We use the Big bang theory currently to conceptualize the universe origin.
