hello, I have a couple questions about #physics more precisely #relativity

How do I actually use #metric #tensors? Do I just do a dot product over the elements with a vector? If a metric tensor has a variable inside, does that variable comes from the vector and I just replace it? After I replace the vector and do the equation, only then I do the dot product?

If I want to have the inverse of a metric tensor, do I just do a #matrix inversion?

A while back, a reddit user called GhostMosquito posted a #short-story to the subreddit #twosentencehorror I really liked it and got permission from them to interpret the story into a #comic format and this is the #webcomic I came up with!

Hope you like it because I'm quite proud of this wee #comicstrip
