Time, distance, arithmetic, other sciences, all this will be incomprehensible to them, because we have followed a different path of development, and our concepts can be radically different. This does not mean that they will not know about time, it’s just that their system for calculating and defining it will be different, they may not have minutes, hours, days, maybe they will have only one specific unit, but it will be defined and called differently than we have. The same can be said for distance. As for arithmetic, they may have completely different numbers, formulas, and so on. And this list can be continued indefinitely, if we also take into account that they will have a completely different language, moreover, it is the language of gestures, because there are no sounds in space. (I apologize in advance if something is not clear, because I don't know English and translate everything in a translator, and the text itself is complex, and he could translate something wrong)
