Doctor who's timeline Infinitely is too3) It doesn’t even matter since Ben 10 clearly functions differently and also has a statement of space-time being eternal. 4) “Type 2: Temporal Singularity: Characters with this type of Acausality do not exist in either the past or the future, only the present.”
Present: the period of time now occurring.
Literally less than 0 seconds pass from our perspective for Ben 10 characters from when they are born to when they die. So by all means they would be living purely in the present during their entire lifespan.
You finding this particular justification for type 2 acausality odd implies that Dr. Who characters may not have a counter for it as their time travel tech needs to be very precise for a successful time travel kill.
“The end state of an open universe will, given absolutely infinite past time, extend to infinity. Our universe is open. Therefore at some future point it will expand to infinity. An infinitely expanded universe will exhibit the following characteristics: zero local Einsteinian space-time curvature, and little, if any, matter over vast ranges of space-times.
Such an area of space-time can be regarded mathematically as a domain of De Sitter space. An empty De Sitter space can be shown to lead without additional causal interaction to the creation of a further universe similar to our own. Thus as our universe approaches heat death, it will naturally ‘give birth’ to one, or more, successor universes. -The taking of planet 5
Also, Ben 10's timestream would give Acausality type 4, instead of 2, since regardless of how it works it still has a past and future
