this "research" is simply hilarious. in their desperation they are getting more and more fanciful with each passing year. I think in a few years hence we can expect an astrophysical mythology rivaling Tolkien's Middle Earth Saga - and it might be, to quote the article, "the most exciting explanation". I like good stories so who am I to complain? But for this group of self-appointed thinkers-for-humanity who allegedly do not brook anything less than experimentally-verifiable and independently reproducible real-world facts, it would be an embarrassing apology for a credible model of the cosmos. The researchers looking for "exciting" solutions can keep dreaming up universes and we will keep clubbing them in a single "grand pluriverse". Hello, sir, it's turtle's all the way down. Beat that if you can. Even if there be multiple self-contained closed-systems which might qualify for "individual universes" I do not think that humans will ever even approach a solution to the mystery of the cosmos. Even if their flights of fancy offer them "exciting" odysseys into the world of possibilities, they will keep groping in the dark until the scrolls of heavens are rolled up and truth becomes self-evidently manifest to even the most stubborn skeptic. And Allah ta'ala knows best.
