Is there a way to see the world live?

If you mean get a "real time" satellite view similar to google Earth, no. Try getting a job at a "spy" agency, although they still experience delays of minutes to hours in satellite images (as far as I know). On the other hand, there are many, many live Web Cams around the world with real time views of city streets and the like. See the link (one of many such Web Cam aggregators) for more.
