perfect answer before i even got to ask the question. Thank you!
Also there is Codecademy. Pretty good, free learning for beginners. For pro courses it costs extra. And of course there is the Odin Project (very good but extremely reading heavy, completely free). And there is the also free Harvards CS50 a complete computer science course. It is praised a lot.
No, i am not assuming that. I was correcting you on 'knowingly' and 'the sun rather than the earth'. When earth and suns position are relative to one another and can be calculated, therefore in a universal sense are both non-absolute, because as you correctly state, the suns position is non-absolute.
We can gladly discuss my assumption that we wouldn't be able to tell a time machine what the position relative to the earth would be, as a time machine is in a universal sense rather than just earthly(?). Would that work like a rocket ship, starting form earth, going to places we can see from earth, or is it about dimensions the universe and so on?
Other than that you misunderstood my post.
