Collapse the Earth into a black hole and it will still have the same mass as the Earth does now.
Try carrying that around in a Chevy.
A black hole the size of an electron has a hundred times the mass of the Great Pyramid of Giza.
Nice suspension on that Chevy.
It's created from sub-atomic particles in his story. It would have almost no meaningful mass. A black hole is curvature of space, which has to do as much with density of the matter causing it as the amount. Theoretically, the mass of a pencil can be reduced down to an area small enough that it curves space into a black hole. It's still the mass of a pencil, though. Not sure how you are supposed to contain something like that or keep it intact for long, or even how that really aids in time travel.. just saying.. the black hole part is the least problematic aspect of his story.
