Realspace

Realspace is the dimension in this universe which many objects such as the planets exist on although, some objects such as the AzaStar have mechanisms that shift it so, it sits in multiple spaces however, this technology takes a significant power source compared to normal dimension shifts.

Theory Origins
The concept of realspace was formulated to label this space in contrast to other dimensions such as cyberspace, hyperspace and the time stream itself and was created by a scientist associated with the IG itself although, it remains unknown as to who this individual actually is as to this day.

Dimension Origins
Realspace itself was one of the first dimensions to form in this universe following the time stream and the big bang itself which is said to be the birthplace of a lot of the species that currently inhabit this universe whether they're powerful aliens or weaker species.

The dimension itself formed from the sheer energy of the big bang which carved out this new dimension within the universe itself which while it's not a data dimension, it is still full of abundant resources which the species that inhabited the universe used back in the first era before they evolved beyond the need of resources.
