I've heard people in that field talk about the possibility of loops in the time dimension, but infinitesimally short period of time is involved and local. Not enough to call it the past though.
PP is technically - which is to say logically - correct.
As far as rejecting the point outright, well for myself, I'm not in the string field or quantum physics, but I used to read some pretty reliable sources, and bleed back was put to bed a while ago (years) ... non event now as far as I know apart from a few people who missed that memo - but would consider the possibility there's been new discoveries the last few years and with new theories, the possibility is tangible once more.
Attacking the publication's track record, rather than the article's content, is clearly covered by PP's cited definition:
"a rhetorical strategy where the speaker attacks the character, motive, or some other attribute of the person making an argument rather than attacking the substance of the argument itself"
This reminds me of an old joke my grandfather told me:
two hacker news commenters are climbing up a mountain
one of them loses his footing and falls on his butt, and asks the other to help pull him up
the other responds that this looks like a textbook case of slippery slope fall-assy and that it is beneath his intellectual dignity to even consider responding on the merits and further...
while he continues on the first commenter falls into an ice crevice and dies
ad hominem? "add Vice and 'em", I say, to your list of unreliable sources, for exaggeration, arguments of convenience, burying any counter-evidence...
I ask this question without ascribing credibility or lack thereof for Vice, but just in general.
(Also, juridical persons and natural persons are a lot more similar than US states and states of matter; it is not just a distantly related etymology; the former literally refers to having legal attributes of the latter.)
