Celebrity Solstice was, at 122,000 GT, the largest ship to be built at a German shipyard, but this record was surpassed by the Disney Dream, a 128,000 GT cruise ship of the Disney Cruise Line.
Languages can definitely change and they can diverge. For example, Latin split up into the modern Romance languages: Portuguese, Spanish, Romanian, Galician, etc. This is less known, but languages can also converge: those languages are called creole. Some people argue that English is also similar to a creole: a mix of Germanic and French.
Most words are said a little differently in Spanish and French, so the two are called different languages. Most languages belong to a language family, but some languages do not. These languages are called Language isolates. There also are Constructed languages, like for example Esperanto.
