I hope I am not hijacking a thread here, but it seemed appropriate to ask here rather than creating a new thread... how do black holes gain mass, or merge with another, if nothing can be observed to enter the BH in finite time? Do they get bigger before anything passes the EH? Thank you for...

Thank you for your answer. If I may with a follow up question, at the beginning, was time affected by inflation, or was the inflation itself the primary cause of the relative motion of anything that existed? also, please let me know if I should be posting elsewhere with such ignorant...

Basically if space is can be considered an observer and if space is 'stretching', is it moving relative to itself? or if objects are moving relative to the stretched space, is time not affected? also at the big bang, if objects are moving relative to space at relativistic speeds, would time be...

does inflation affect time? my question arises from @ ~7:30min. if space itself can be used as a reference point for speed, is it an omnipresent observer? is it therefore not excepted from SR if space is moving relative to space? I have searched the forums already, I am trying not to...
