Something almost every #SciFi story gets wrong when they're talking to someone from another planet or galaxy or whatever, is time.

Our measure of time comes from how fast the Earth is spinning and how long it takes for the Earth to make a trip around our Sun.

People from different planets that are spinning at different speeds than Earth and that take wildly different amounts of time to go around their Suns would have no concept what we mean when we say an hour or a year, or any Earthly measure of time.

Actually, I've never seen one get it right.

There are planets out there that go all the way around their Sun faster than they rotate, making their days longer than their years.
