Might be LLM bunk. If you’re consuming science news, then first: I recommend PBS Spacetime and second: if a quantum gravity was actually formulated, you’d hear about it there first. It might actually be exciting enough to make CNN.
More to the point though: this sorta thing is too good to be true. Plenty of things are, and are still real. But even still they bear a second glance. This one doesn’t pass the sniff test.
