That's a very good reasoning why it is an unlikely thing to be. But the sensitivity of humans to gravitational differences is not a law of physics. This is a very important distinction.
The phrase "breaks the laws of physics" is not just a rhetorical flourish.
If I point at a go-kart looking thing and say "that thing can go 0.8 Mach" that's a practical impossibility. For many reasons it is very unlikely, to be true. But does not break the laws of physics. (Who knows, maybe it has a nuke under it, which can loft it that fast for one glorious moment of go-karting fame.)
If I point at the same go-kart looking object and say "that thing can go 1.2c" that is a whole different ballpark. It might still happen, but if it happens that will make us re-evaluate nearly everything we think we know about how the universe works. This is what it means that something "breaks the laws of physics".
