I am still in high school and so i am fairly new to the world of physics. I am curious as to if the physicists of a large multitude of nations collaborate with their research and their findings. Or do countries try to keep their discoveries to themselves in an attempt to get ahead? It seems like humanity's understanding of the universe would be reaching its fullest potential if scientists were all working together. Besides all of the various national physics societies that many counties have, the idea of an international institute of physics seems just that, ideal. I am aware that there is some cooperation between countries in physics, I am just not sure of the extent.
