You still need to write the context in which he speaks!! For I have no clue!!!

Generally it's not a intelligible sentence. Do you have any context with it? The only time I'd say it would be if someone answered a question of mine with, "Nothing". Like, "Where have you been tonight?" - "out" - "what have you been doing?" - "Nothing". Then her mobile phone kept ringing through the night, I'd think, "there's more to 'nothing' than I first thought". But other than that, I'd never say it, it doesn't make sense.

When you think of nothing, do you think of space, God, the deep sea, an empty mind? All of these versions of nothing have more to than than we can know. Do not change the word to to of. It is using the saying "there is something to that" as a starting place for an understanding. It means you might have no way to "put your finger on" what "it" is, but you can tell there is something there. If you use "of" it will loose the connection to that already understood concept. No context needed this time- for me.

“There's More to Nothing Than We Knew.” That's the title of a glowing write-up in the New York Times Science section by Dennis Overbye :-)
