Why doesn't the whole world have 1 dominant language?
I am trying to get a better understanding for a study I am doing

Because, historically, societies and cultures became established in isolation and only gradually began to come in contact with one another. So, different languages grew up in different areas. The Romance languages have much in common because peoples in those areas were geographically close to one another.
I like babs_irish's answer! Also you can look at the cultures themselves. Take French, for example. The french language is very flowing and smooth. French art is sofisticated and painted with elegant strokes. French food is savory. French music (classical-impressionist) follows the flow of the language. The language reflects the culture, as does the food, art, and music. Another example is German. The German language is rhythmic, precise and gutteral. German music (take hymns for example) is not flowing, but choppy. This is because the language reflects in the music. German food is meant to fill you up. I could give more examples (Irish, Spanish, Chinese, Russian, etc.) Think about all the cultures and languages of the world, and think of how the language, food, art, and music all reflect each other.

Oh, but it will my young padawan. Soon the whole world shall be speaking Spanglish. Soon.... mwahaha (evil laugh).
Plain and simple... God wanted to keep things interesting! 
It is impossible.Although it is impossible,I think that the english is a dominate language,a world language.It is used in north and south american states,in european states, in asian states and in Australia.Everybody know to say ''how are you?'',but a few know what ''Wie geht's dir?'' means.Wie geht's dir? means in german ''How are you?''.If you want to navigate on the internet, you have to understand english.Although the english is a dominat language,it cannot replace the other languages.The spanishes always will say that el jamón is jamón .They never will say el jamón is ham.Who didn't eat jamón,he could say jamón is ham.This example is an argument,my argument which says it impossible for a dominante language to replace the other languages.It is true,my example is not a philosophic one.The diversity means curiosity and beauty too.
Es imposible.Aunque es imposible,creo que el ingles es una lengua dominante,una lengua mundial.Se usa en estados norteamericanos y suramericanos,en estados europeos,en estados asiáticos y en Australia.Todos saben decir '' how are you?'', pero pocos saben qué semnifica ''Wie geht's dir?''. Wie geht's dir? semnifica en alemán ''How are you?'' =''¿Comó estas?''.Si quieres navegar en el internet tú tienes que entender ingles.Aunque el ingles es una lengua dominante, no puede sustituir a la otras lenguas.Los españoles siempre dirán que el jamón is jamón.Ellos nunca dirán que el jamón es ham.Quien no comió el jamón,podria decir que el jamón es ham.Este ejemplo es un argumento,mi argumento que dice que es imposible que una lengua dominante sustituya las otras lenguas.My ejemplo no es uno filosófico.La diversidad semnifica curiosidad y,tambien belleza.
When you say "dominant language" one could say it's already there, and it's English. The most obvious point is this.
You and your colony spent your entire lives on Mars
My colony and I spent our entire lives on Saturn
And everyone else spent their entire lives on Uranus
We have NO language to start with.
How likely would it be that we somehow end up speaking the same "language" using the same patterns to communicate. The same thought process in expressing every thought... the same writing system...
It's not likely at all is it?
Well, the world wasn't always traveled with "ease" ...the world wasn't always thought to be round either... and different people, from different lands, developed different sets of speech patterns to communicate with one another. Many languages are linked however, based primarily of course on proximity.
It's a rather cut and dry subject.
Simple, language is learn not instinct and in order to learn most humans need to become in contact while the brain still developing. Im not sayings it cant be learn later in life, it just take a lot of work. The whole world would have to agree on one and mostly talk to all xhildren in the world using that language. Simple, thats why.
If someone had conquered the world, we may have one language. What language people speak often follows on from who they were conquered by, in the case where they speak a language not native to the area. An example of this would be the spread of English across the globe. English is not an easy language to learn by any means, and most likely is only spoken widely because of conquest (North America, the British Empire etc).
Having added that, I also agree with what Babs_Irish said. Conquest, trade and common origin are, to me, why similar languages are spoken in different areas.
It would be a good idea like my Spanish teacher said.
"A perfect language"
No irregulares, masc o fem, o otras cosas.
