Is Physics a Universal Language?

Physicists like to believe that their work reveals something deeply true about the Universe. Alien scientists, they suspect, are discovering the same concepts, even if they may express them in alien languages. But how do we know? If aliens arrived on Earth, could we use physics and math to bridge the gap? Before they arrive, we can glimpse the possibilities by looking at the foundations of physics, to search for clues about whether they are universal, or reflect something of our humanity.
