The answer to that question will fill several college degrees and a few lifetimes of study. The short answer is "We're not sure yet."
At present, it would appear to be mostly "empty space". But is it really "empty", or is it filled with transient and short-lived "virtual particles"? Is matter really "solid", or is it just some sort of bound energy? Are we really here, or is everything including me, the state of California and all of WikiAnswers some sort of fantasy that I've dreamed up in my mind?
Perhaps you'll write the book about this.
The general large scale structure of the observed universe is:
large clusters of galaxies ("superclusters") separated by large "voids" with not much in them.
There are also features called "walls" which contain many galaxies.
There are many other details, but that's the basic information.
The universe doesn't appear to have any large-scale structure; it's pretty homogeneous.
Mass and charge give the universe structure.
The universe is structured like a cuboctahedron.
The universe is all that exists. The observable universe is all that we can see.
The universe is all of reality, which includes physical and mental objects. It is the subject of study in science, philosophy, and religion.
the arrangement of the universe is:
1. Earth
2. Solar System
3. Milky Way
4. Universe

Newton did not change the universe he described it mathematically.
In 1924, Alexander Friedman noted that the equations of general relativity have only two solutions: an expanding universe or a contracting universe. Independently of that work, in 1927 Georges LeMaitre used those same equations to show that an expanding universe was the only reasonable description of our Universe. His ideas were later described as a "big bang" by those who opposed them.
It is the current working theory of the origin of the universe. It is the paradigm that Astronomy is based upon. But, new evidence is always being described. The theory itself might change as our knowledge grows.
The theologian and physician Georges Lemaître is believed to be the founder of the big bang theory. He first described the conditions within the first seconds of our universe 1931,with the term "primordial atom".The Big Bang theory explains only that such a rapid expansion caused the young universe to cool and resulted in its present continuously expanding state.No common agreement exists as to the conditions leading up to the Big Bang, for it is believed that conditions were too different for our knowledge to be applicable.It was the British mathematician Sir Fred Hoyle who coined the phrase "Big bang" in a radio broadcast in 1949. [He favoured an alternate hypothesis, subsequently abandoned.]
The Icelandic view of the universe described by Sturluson talks about the universe in which the giants and the gods battle.
Claudius Ptolemy was the ancient Greek astronomer who described a geocentric universe in his book "Almagest." He believed that the Earth was at the center of the universe, with the planets and stars orbiting around it.

The term 'super-universe' is basically a synonym for the multiverse, a hypothetically larger cosmos than our observable universe.

Science is a means of understanding the universe in which we live.

That was the general belief held in antiquity.
Newton did not change the universe he described it mathematically.
Copernicus
Objects that move around other objects in the universe are said to be orbiting it, or in orbit.
