There are no "massive" holes in the theory (please point them out to me). Whoever wrote the article in the OP is a dumb fukk and doesn't understand the big bang theory.
"Whereas the Planck results “prove that inflation is correct”, they leave open the question of how inflation happened, Dvali adds. The study could help to show how inflation is triggered by the motion of the Universe through a higher-dimensional reality, he says."
Again, this study doesn't disprove the big bang theory, they're trying to explain why inflation occurred in the first place.
"There are problems with the Big Bang theory, though until now we haven't really had any better ideas, so we've stuck with it as a plausible explanation for the beginning of the universe. For one, we have no idea what would trigger an ultradense pinpoint of matter to explode outwards."
People keep trying to explain why the matter expanded, but the Big Bang theory has nothing to do with "WHY" the matter expanded. So just because you answer the question of "why" expansion happened, it has NOTHING to do with the Big Bang theory.
