Are the findings of this article theoretically possible and / or believable?
I understand that the specific publication is normally reputable, but I am having trouble believing some of the conclusions the researchers have drawn. The article was published at the end of March of this year in a well-known journal.
I find it odd that there is only one reference to this article in any other publication discussing it, specifically given that the one in question is Popular Mechanics. I have read of others and experienced first-hand that Popular Mechanics isn't always the most reliable.
Especially as they often try to draw in readers/clicks to their articles as many sites do by giving somewhat flashy headlines as evidenced by "Scientists Say There’s a Place in Our Universe Where Time Moves Backwards." Which was published on May 7th also of this year. Now this might not necessarily warrant skepticism or a cynical response always.
However, I thought I would throw the subject to people with more experience in the field of Theoretical Physics than myself.
