As you see in that equation, vb must be enormously (ridiculously) large to have the desired bubble thickness. White really isn't overturning any old thought with this paper; while it is perfectly true that thicker walls help, he has not addressed the factors which have caused scientists to consider only microscopic-thickness walls viable.

His "oscillations" don't sit well with GTR as in GTR they are just a constant. He may be pleading an alternate theory of gravity but that's not a good start.

He also neglects to mention the gravitational effects the bubble will have on the ship.

The renownedness of a scientist has no effect on the validity of their claims, of course; every scientist must be questioned and appeals to authority are not scientific. Remember that arXiv articles are not necessarily peer-reviewed and that there is some 'corruption' in the peer-review process in smaller journals.
