I accept your tacit confession that I openly and transparently cited a university webpage hyperlink as the source of the spacetime interval equation, and that I did not surreptitiously use a Quora source without citation like you do.
Vectors are first semester introductory physics. That's how I know you don't have any college science background. Things that sound exotic to you are covered in introductory science classes.
Now, a four dimensional vector is pretty far out there in terms of basic introductory physics.
Okay. It's obvious you are lying, since you don't seem to understand vector mathematics.
Science is not a class. Science is a set of falsifiable theories. You deny and discard several of them. You have in the past, for example, discarded the 1st and 2nd laws of thermodynamics and the Stefan-Boltzmann law. Now you discard Newton's Law of Motion, Einsteins laws, Planck's laws, and Heisenberg's laws. You've even denied Galileo's laws and Kepler's laws.
You deny and discard vector mathematics as well as principals of algebra, random number mathematics, probability mathematics, and statistical mathematics.
Science is not a college nor a university. It is not a class, degree, license, certification, or any other form of sanctification. It is not any government or government agency. It is not a book, magazine, journal, website, or pamphlet. It has no religion. It has no politics. It is not an association, academy, club, group, or society. It is not people at all.
Science is a set of falsifiable theories. That's it. That's all.
Mathematics is not a college nor a university. It is not a class, degree, license, certification, or any other form of sanctification. It is not any government or government agency. It is not a book, magazine, journal, website, or pamphlet. It has no religion. It has no politics. It is not an association, academy, club, group, or society. It is not people at all.
Mathematics is a closed functional set of rules (known as 'axioms) and formal proofs extending those rules. That's it. That's all.
You obviously have no idea how conduct a vector mathematics equation. You don't even know where that equation comes from.
