Did you read the paper, or are you just trusting blindly whatever she tells you she found there and whatever she tells you it means?
Who is this woman anyway?
Because as someone who did study physics I've been hearing about quacks, grifters and nutjobs left and right arguing that relativity proves causality doesn't exist for over a decade now and I've wasted far too much time of my life already actually hearing their arguments out; They're pure nonsense and they themselves don't understand what they're saying.
There is a case in which a mathematical formula in a specific condition tells you that an event happens before the action that causes it. But just because an equation tells you that doesn't mean it is real. Physics equations are just long sentences given a compact form, they're descriptions humans have made to explain things in the observable universe. And the name we give collections of these propositions or the complete argument they form is too something made up by people.
Gravity doesn't exist, but when an object exists in the universe it has mass, and mass -somehow- communicates with all the other mass in the universe that it exists, and every mass in the universe tries to get closer to the rest of the mass, and we call the effects of that gravity... what is mass? umm.... that's a story for another day.
