"Rajendra Gupta, an adjunct professor of physics, and postdoctoral researcher Nikolaos Samaras have spent much of the past two years checking their model."

I do see more than one scientist listed in the article, sure one team but it is not a single person. I do hold your reservations on the model being truely accurate as it doesn't include dark matter or dark energy... but that doesn't mean this isn't something to be further tested or reviewed...
