Maybe they need update, I dont know. But when some one makes video about hell i expect to understand it in the light of Bible without having to consult someone who is scientist... Somebody who knows physics and time well. Because if you take that line of trying to fit visions into reality of scripture by using higher science than what we are used to understanding, then it becomes vague wheter or not the visions fit in bible. Because we dont really know how the heavenly realms are and how hell is. And if we start thinking there maybe or may not be this and that (mass & time) then what else can somebody claim as there is no evidence for us to tell what kinda of realm there is. So i think we should stick on what we know or else we can only assume. And i dont think we need higher science because people have always had visions and used their best ability to descripde what they seen and its not too hard to understand. No where in the bible is visions that are Both current and future in sense that time would not exist on the spiritual realm... Always in bible there's futures visions and prophecies , things that have not happened yet but will and in John revelation we see the angels of heaven and horsemen of Lord to deal with earth in various ways. So no explanation of time not being same in there (heavenly realm) needed. It seems all perfectly understandable without higher science in the bible. Bottom line is if somebody makes video that does not lineup with bible in sensible way like rest of the scripture in the bible about hell and all the visions then I cant really believe it and ask why its so out of the line?
