"Nothing can go wrong" vs " nothing could go wrong"

“Nothing can go wrong” and " nothing could go wrong" , what is the difference between the two expressions?


Based only on what you have given us, the second is a more tentative conclusion.

Can the first one be used to mean “nothing is allowed to go wrong?”

Yes, but it seems an odd regulation, one that is bound to fail. Things go wrong.

If I ask “is everything all ready,” which one can be used?

Read and apply my first post comment.

ok, then it means both work, but with a defference. Right? Sorry, I am not very bright.


Thank you for your time.
