First off, they have "theorized" that physics could be different in different regions of spacetime as an intellectual possibility to play with, but all observations so far have suggested it isn't true.
And the theory would be for different regions of spacetime, not for different beings. Once they entered our region they'd be fukked cause they'd have to obey our region's rules. So even if they could travel faster than light in some different region 2 billion light years away, they'd lose that ability millions of light years before they got to us.
That was the starting issue with the theory even on paper. That's why people like Hawking proposed spinning or electric charge to keep the wormhole open, though even that doesn't fully solve the issue.
But once you get past the paperwork and get to actual observation, the issue is that space appears to be flat on every large scale. So there are no shortcuts for a wormhole to exploit. If you want a detailed explanation:

Quantum entanglement isn't something moving faster than light.
First off, I'm trained as and have worked as a physicist, I'm not just someone who "reads about it."
Second, scientists are FAR more coherent in what they believe than you are claiming. If they were as vague in their beliefs as you suggest, how would they even evaluate the results of their experiments? Any experiment they run relies on assuming that thousands of different physical laws and constants are irrefutable and then testing for one question on the margins. If they were talking like you, then no experiment would ever be understandable because any of the thousands of laws they were using to evaluate their experiment could be wrong at any time, and thus they'd have no way to even guess which of those thousands of possible uncertainties was leading to their results.
