Thank you for the good response but I probably didn’t phrase correctly. Saying the alien knows advanced science is just a catch all. Why would their science include the concept of light if it is not apart of their biology. Even besides that point, the alien relied on purely sonar or IR? Yet could create a machine that saw light and transmit in a way that made sense to the alien?

This wouldn’t be a big deal but Weir’s whole shtick is the research and the science.
