I feel like this may not be an answerable question and more specifically, that it may not be on topic, but I am curious and can not find anything online to satiate my interest...
Here is the question as I would address it:
Given the fan theory that has made the rounds to date has held up relatively well can we now complete and authenticate the idea based on what we know from events of Infinity War?
If it is not on topic is there a way I can rephrase it to "make it so?"
