Cosmologically? yes nihilism makes sense.

On a human scale? No, your actions and inactions have rippling consequences on the world around you, and to reject these consequences is to reject responsibility for sharing a world with others, which in my opinion is a selfish and childish thing to do.

Absurdism seems more rational than nihilism on a human scale, since it admits that the world is chaos and to fully embrace this entropy as a means to not take the consequences of life too seriously.

Absurdism is a fantastic coping mechanism for the harsh realities of life. Nihilism really does not accomplish anything, in my opinion.
