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.
