The flaws of this crackpot book are many and include:
Redefining the concept of infinity as a length with magnitude.
Defining a line as a series of points written as zeros, treating them as numbers so that they add up to zero and then treating the number zero as a point again!
A really bad atomic model "proving" that a electron orbiting a proton has a ground state that it cannot decay from by creating a new physical law.
Using the high school description of a neutron as a proton plus an electron and not realizing that this is just his atomic model!
Postulating that galaxies have "galactic cores" which are super massive objects that are not quite black holes and not realizing that the centre of the Milky Way is well observed. These recycle stars into hydrogen. Oddly enough astronomers have not noticed dozens of stars vanishing from the galactic centre in the many images that they have taken over the last few decades.
Conclusion: Bad mathematics and even worse physics.
