It sounds better with the word "the" added: The impossible is possible.
Just adding my voice to the opinion that you need "the" before "impossible" in English.
To me this seems like a meaningless contradiction. What does it mean? When would you use it?
It seems to be a motivational quote
It's bossthink. It's what your boss thinks when you tell them something is impossible. "Prepare this presentation until tomorrow" "That's impossible!" "I'm sure you can do it, you're a professional" That.
Niemożliwe jest niemożliwe
