I am not even sure what this discussion is supposed to be about, no offense meant. Is it time (my actual guess)? Space (also valid)? Alternate dimensions (actually universes. Dimension(s) has(ve) to do with length, width, depth, linear time, etc.)?
What would help is an actual logic based argument, rather than a few sentences that make illogical jumps. The original premise of the "Friends argument" (which is the spawning of alternate universes) does not adequately link to the end of time. The question I ask is: How does the creation of another universe that breaks off from another universe in the form as a choice make it necessary that the end of time "... will come like every other day"? There is nothing linking that premise to the conclusion. If there is, and I have just missed it, please tell me.
However, based on the premise that this is a discussion about the end of time, I have to say that there may be an end. This
is a great example of how time can end. Effectively, you neither have life (no more chemical reactions), nor any kinetic energy left to run a clock to measure time. This is only one example (a very possible one), but is not the only one.
