As a starter, what's the nature of gravity? Apparently it has an infinite range through space, and weakens as the inverse-square of the distance between bodies... it travels at the same speed as light, Some physicists beleve it can be tested mathmatically by the Superstring Theory but just as many, maybe more have great doubts that such an explanation is feasible. Few things are so universally experienced and still so little is known...
We don't even know all the questions!
The Victorians thought they were on the verge of knowing nearly everything about space/earth/nature, and it was just a case of tidying things up.
Look at what we've learned since then about things they never even dreamt of.
In a hundred years time, people will look back on us today, and see our grasp of scientific knowledge in the same way as we look back on the Victorians.

Here's a top 100 here:

My top 4 below
1) There are 4 fundamental forces 2 have been "unified" shown to be 2 aspects of the same thing - can the remaining forces be unified into one grand unified theory
2) The Goldilocks problem - there are a number of fundamental quantities such as the strength of the 4 forces above and nature of the fundamental forces which if they were different would result in a universe with no matter or no stars - are these quantities truely unrelated and how did they get set the way they are? are there other universes with different quantities?
3) How did life first arise in detail. We know that organic molecules can arise from inorganic sources but how did they first concentrate and assemble into the first self- replicating chemicals
4) What is the nature of conciousness? how does the mind work and how does this relate to brain function?

How did I manage to lose nearly all my hair bands when I lived on my own in a confined space? (Well I've never had a satisfactory answer!)
I think in general as a species we always think we 'know' a lot but actually when you think about it, years a go they 'knew' that the earth was flat, they 'knew' that the body was made up of four humours ect... so with that in mind, imagine what we 'know' that future generations will think again on. So I guess as long as you don't pressume we know all the answers there's a heck of a lot of questions still to be asked.
Personally, my interest of the month (actually it's lasted a couple of months now) is regarding all the creatures that live deep in the sea and ecosystems that are being set up without sunlight (if I have understood correctly), they're discovering new creatures all the time. There's got to be hundreds of questions about that topic alone.
