It's not up to me to prove Penrose wrong, but for Penrose to prove himself right.
Like I said before, I'm a contrarian. I'm not convinced about the Big Bang, nor am I convinced that there is such things as dark energy or dark matter, as evinced by my two articles below:

But in both articles, I acknowledge that I am profoundly ignorant. I freely acknowledge that any first-year astrophysics student would know more than a retired sailor like me. That's why I can appreciate Prof. Siegel's admonition.
Read again the last two paragraphs of his article. He does not deny for a moment Penrose's past accomplishments, but warns (in so many words) of the folly of pride, of falling into the trap that so many great people, tricked by their own accomplishments into "believing the hype", lay for themselves.
Prof. Siegel is rightly reminding everyone of the importance of humility. His audience includes himself, for he could not have written that article if he did not understand the need for humility even among the greatly learned.
