The whole thing looks pretty fishy to me. Einstein did not complete a unified field theory that actually worked. Theories are actually a big deal, and tons of them come and go before there is a successful one. It not only needs to explain everything we already know, but predict nothing in contradiction with what we know, and predict new results that make it worth pursuing. That's very tough to accomplish. From the rest of the quotes, it looks like a lot of dubious claims presented with no real evidence.
