I am always amazed by the amount of new discoveries that are still possible in science. We might think that we have an adequate picture of our universe and how it operates, but then we discover yet another subatomic particle or another strange fact about the movement and organization of the galaxies. For all we know the smallest subatomic particles yet discovered may be made up of yet smaller subatomic particles, and the laws of physics that we use today will be completely invalidated by a future better understanding of dark matter and its effect on our universe. It is humbling and incredible to think about how much there is yet to discover.

This one is always fascinating for me to think about: > There is considerable speculation as to why the observable universe is apparently almost entirely matter, whether there exist other places that are almost entirely antimatter instead, and what might be possible if antimatter could be harnessed, but at this time the apparent asymmetry of matter and antimatter in the visible universe is one of the greatest unsolved problems in physics. http://en.wikipedia.org/wiki/Antimatter http://en.wikipedia.org/wiki/Antimatter

You don't even have to go as far as dark matter, dark energy, or indeed space at all to find amazing undiscovered principles in physics. For example: put a ball on your desk. Now push it. Did it resist? Why? Well, sure, there's a component of friction, but even without friction it would resist your push...so, why? Inertia, right? But where does inertia come from?!? http://en.wikipedia.org/wiki/Inertia#Source_of_Inertia http://en.wikipedia.org/wiki/Inertia#Source_of_Inertia

> then we discover yet another subatomic particle I guess that is a general principle: Just look at the thing (= what you have/what we know so far), then zoom in, ask: "Why is it that this is how it is?" I guess you can do that on and for just anything we know, therefore we won't ever have a complete picture.
