How it works

Looking at your phone late into the night every day. Look at the picture: could this be good for your health?
Use 「はずがない」 to strongly reject a possibility based on what you know.
「はずだ」 means you expect something to be the case; 「はずがない」 means you judge that it cannot be the case.
The example about effort rejects “gaining ability without making any effort.” It does not say that ability cannot grow.
「はずがありません」 in the examples is the polite form. The negation is just as strong.
