RE: What is your take on the Void
SUBTOPIC; Understanding the question?

IllusiveOwl, et al,
All excellent questions. Let us take them one at a time.
How do you see the universe?
(COMMENT)
The universe is viewed in many different ways.
- By examining objects using visible light (optical astronomy).
- By looking at objects with detectors sensitive to Infrared, ultraviolet, and other emitted radio waves (including objects at submillimetre wavelengths).
- By performing spectrum analysis on all the energy that can be detected from the distant object.
- By looking at the Red-shift and Blue-shift of objects in the expanding fabric of space.
- By examining the gravitational effect the object has on nearby objects.
- By focusing detection capabilities on the x-rays, gamma-rays, cosmic-rays, and searching for neutrinos.
- etc
(COMMENT)
This question is beyond the knowledge of science and is one of the many metaphysical boundaries. There are some very good theoretical conjectures and some nice mathematical presentations. But it is still supposition and speculation. The Milky Way is over 100K Lightyears in its diameter. Right now the terrestrial radio bubble is about 120 Lightyears in radius. That represents the farthest intelligence of out species could have traveled, plus the electromagnetic noise that might be considered a signal associated with a nitrogen-oxygen atmosphere planet that would reflect stellar radiation.
Does it have a shell, an inside & outside?
(COMMENT)
Again, science cannot answer this question. The study of science includes the use of the scientific method. At the current time, things like "String Theory" (as an example) cannot be tested using the scientific method.
I am pretty sure that no one in my generation knows the answer to your question. The probability is that there is no shell, that the fabric of space-time is already out there and the universe is just expanding into it. (Someone can probably write you a lot of mumbo-jumbo quantum field theory (QFT) and relativity (GR) using quantum mechanics (QM). I'll be honest, I have a minuscule understanding of QM. It takes people like Sir Roger Penrose to figure out if. there is a realistic and probable. answer. I get a headache just thinking about.
Because only that which is outside the universe could be nothing, but that would then be something, and then would that nothing have an end?
(COMMENT)
Inside and outside (a three-dimensional object) are concepts that are better left behind in the realm of Newtonian mechanics. The Milky Way is in a local group of galaxies, - which is part of a Virgo Supercluster, - which is in turn part of the giant Laniakea Supercluster. It is ≈ 500 or 600 million Lightyears with 100 million billion solar systems. These numbers and distances are so big that writing them down cannot stimulate the mind to understand the enormity.
What was before the big bang, nothing?
(COMMENT)
The Big Band (bad scientific notation) is the theoretical location from which the first energy was ejected.
.
(COMMENT)
Many claim that the observable universe is ≈ 90 to 100 Billion Lightyears in diameter.
I am not so sure that I am even qualified to answer this question.
Most Respectfully,
