My favorite phrase in the world is 'lingua franca'. It is a medieval Italian phrase that refers to a common language used to bridge between two others, such as for trade. Because of British then American economic and cultural dominance over the past 200 years, English is the bridge language for trade all over the world. The phase itself translates to 'language of the franks' referring to a Germanic language that eventually mixed with Latin to form French.
All of this is very simplified of course but to simplify it even further, this is an Italian phrase that translates to French that means English.
I'm imagining if our galaxy collided with another, but on the far side so scientists announce that the earth will definitely be destroyed in 100 million years when we get to that side.
