The knowledge of the position of the astres is anything but useless! It is one of the most pratical thing you can learn both for modern life application and very traditional use case.

It’s not ‘useless’ knowledge … if learning about the wider universe outside our small planet makes you realize what your place in this reality is, then I really don’t think it is useless, rather it is critically important because it makes our small insignificant existence in this vast universe far more special and humbling to the point where we look and see everything and everyone around us as so miraculous that we should do everything we can to enjoy this time that we have together in peace, love and harmony. It makes you realize its all we have and all we’ll ever be.

Definitely not useless knowledge.

Keeping looking at the stars, I’m watching the same sky as you.
