Two things to make clear first:
* I haven't seen Beyond yet. Use spoiler tags please.
* I posted this here because I want both realities to be explored in light of this question.
Okay. So, suppose Earth was destroyed, either as NuTrek Vulcan was, or some other way.
Given that there are many colonies remaining Humans in transit between worlds could eventually settle on, would there be as much of an effort to establish a New Earth, or would it be seen as speciesist to want to preserve and restart Human civilization's central base of operations, as it were?
Are those Humans living on other worlds for generations Human anymore, or practically aliens because they've developed sub-cultures on long established colony worlds?
Would people disperse among alien worlds and dilute to the point of being erased as other cultures absorbed them?
Would Humans care that Earth was gone (aside from having lost most of their relatives and friends). Where is home anymore?
