Physicists have discovered a jewellike geometric object that dramatically simplifies calculations of particle interactions and challenges the notion that space and time are fundamental components of reality.

 Interesting if fruitful

It's a popular toy theory to play with because it's not so simplified as to be completely trivial, but it has various nice mathematical properties that make it more tractable than realistic theories.

Better?
That site still does not fill me with confidence, and the credibility of the source is still a major factor for me when considering "everything the EXPERTS know is STUPID" claims.

The basic problem with quantum anything is that it's very hard to think about because our brains expect the world to work in a ways that things just don't, on a quantum scale.
I'd take the article as saying "we've got a candidate general abstraction, an elegant and computationally simple abstraction, for some quantum stuff that used to be really really really hard to calculate. The particular abstraction requires us to formally pitch a couple of axiomatic expectations  that things affect only the things they're near, and that the probabilities of the possible events always adds up to one  which makes people uneasy, but we Had Our Suspicions About That from these other results over here."
Even if it is quantum gravity, it's not clear that we'd expect any change in capability whatsoever.
