Cometary nuclei are composed of an amalgamation of rock, dust, water ice, and frozen gases such as carbon dioxide, carbon monoxide, methane, and ammonia.Dangerous Close Cometary Encounters occur when:
As such, they are popularly described as "dirty snowballs" after Fred Whipple's model.
However, some comets may have a higher dust content, leading them to be called "icy dirtballs".

As soon as Gibbs' article hit the Internet, news about it spread rapidly through social media (we covered it at Ars too), arousing the skepticism of cipher geeks and scholars alike. As Harvard's Houghton Library curator of early modern books John Overholt put it on Twitter, "We're not buying this Voynich thing, right?" Medievalist Kate Wiles, an editor at History Today, replied, "I've yet to see a medievalist who does. Personally I object to his interpretation of abbreviations."

However, this isn't sitting well with people who actually read medieval Latin. Medieval Academy of America director Lisa Fagin Davis told The Atlantic's Sarah Zhang, "They're not grammatically correct. It doesn't result in Latin that makes sense." She added, "Frankly I'm a little surprised the TLS published it...If they had simply sent to it to the Beinecke Library, they would have rebutted it in a heartbeat." The Beinecke Library at Yale is where the Voynich Manuscript is currently kept. Davis noted that a big part of Gibbs' claim rests on the idea that the Voynich Manuscript once had an index that would provide a key to the abbreviations. Unfortunately, he has no evidence for such an index, other than the fact that the book does have a few missing pages.
The idea that the book is a medical treatise on women's health, however, might turn out to be correct. But that wasn't Gibbs' discovery. Many scholars and amateur sleuths had already reached that conclusion, using the same evidence that Gibbs did. Essentially, Gibbs rolled together a bunch of already-existing scholarship and did a highly speculative translation, without even consulting the librarians at the institute where the book resides.
