i bet you seen the other universes theory's how they are like orbs filled with galaxy's what if that was in space engine that would be amazing! if this suggestion was put into the development of space engine!
Hi. This has been proposed before.
The answer is no. The multiverse hypothesis or the many worlds interpretation of quantum mechanics has nothing to do with that depiction of orbs filled with galaxies at all. That is not even inaccurate is just plainly wrong, more than a depiction of something is a symbol used to have some sort of pictorial allusion to the concept. Since Space Engine primary goal is to be realistic this can't be done.
Also this idea is at least very debated . No evidence has been provided for this model nor concepts for actual experiments that could discern between this and other models.
But yeah the primary reason is that SE can't depict things that we are used to just because someone used that orb-like depiction as a metaphor.
