True, but they are not theories of what matter *actually is*. At the turn of last century Rutherford showed that atoms were mostly empty space. Tables and chairs did not suddenly become less solid as a result, but it became clear that their apparent solidity was not actually evidence that atoms are solid all the way through. In a similar fashion, the apparent solidity of matter is not actually evidence that it isn't just fluff all the way down, or part of a computer simulation. Our physical theories describe the behaviour of matter without formally addressing this question at all, despite what prejudices and working assumptions physicists may have about the true basis of physical reality.
