| > Physics used to be "hard science" - Physics is still a hard science. However, the edges of physics are difficult to test. > In cosmology, you can only observe, not experiment Saying that is like saying "we don't know evolution is true, because we don't see new species evolve every day". It's a naive approach to science. In both cases, you can use theories to make predictions about new things to look for. e.g. http://tiktaalik.uchicago.edu/ > Physics is funded because it produced the atomic bomb and semiconductors. Physics is funded because it's cool. And it still gets less funding than major sports leagues. So by your definition, the NFL is funded because it's part of a national defence strategy? |

In general it's also true of almost all astronomical research, and large whacks of geology. Which is fine because experiments are just observations that scientists are the impetus for. Science works by gathering data, experiments just let us produce data to gather at our own speed instead of having to wait around for something to happen and hope we're looking in the right direction when it does. In the case of astronomy instead of relying on experiments to produce more data we mostly build better instruments.
