If we see an explosion today, that means it happened 700 years ago. That's why I am kind of irked at the reporting of this. The reporting kind of assumes a Star Trek/Star Wars type universe where things happen instantly and characters know what happened across the galaxy, when the reality is we are limited to the speed of light. They are missing an opportunity to explain the vastness of space.
Even if the fish can see the surroundings of it's aquarium, could it ever really grasp the reality of it?
I suspect even the "vastness" of space isn't really vast compared to outside the aquarium.
You are assuming that the writer has any idea of the vastness of space.
So it’s a halfvast story?
