Although the theory is promising, the duo point out that they have not yet completed its proof. The theory uses a technical procedure known as renormalization, a mathematical way of dealing with infinities that show up in the calculations.
So far Partanen and Tulkki have shown that this works up to a certain point—for so-called ‘first order’ terms—but they need to make sure the infinities can be eliminated throughout the entire calculation.
“If renormalization doesn’t work for higher order terms, you’ll get infinite results. So it’s vital to show that this renormalization continues to work,” explains Tulkki. “We still have to make a complete proof, but we believe it’s very likely we’ll succeed.”

Physics is not math, you can’t “prove” a physical theory. You make predictions and through experiment or observation Nature has the last word.
Quick, get in contact with the physicists, they need the insight that you got from thinking about a sentence in a pop sci article for 30 seconds.
I am a physicist. String theory already unified QFT and GR and that doesn’t mean it’s a verified physical theory, you need to validate it through experiment. It’s physics 101. Just watch some Sabine H. videos to see how she speaks about string theory being a failure besides being mathematically consistent.
Nothing has unified gr and qft and you’re a liar
No string theory has unified them, it hasn’t been verified. I’m not familiar with the intricacies of string theory, but presumably it is logically consistent. Or “proven”.
It hasn’t been experimentally verified
You have extraordinarily loose standards. Sad.
What? How do you mean.
I said it was logically consistent, which if it wasn’t no one would be shouting from the hills about it, since it would be the same as saying that 5 = 4.
It might be fictious, I.e. the equations don’t relate to reality, but it is good fiction, in that it doesn’t produce nonsense.
