Why we could say we are visible and invisible

We will find in these writings:
1- What are we surrounded by? Mention things that are not seen around you
2- What makes things visible or invisible, any structure or other
3- Where is the universe located in the undefined field?
4- Who can create in the universe and why?
5- Why everything seen and unseen is that way 
6- What are we within respect to the universe, can we travel in any manner

In reading with affiliation, you will find the image that describes what could be found in the invisible universe.
