## Main Question or Discussion Point

1) What exactly does the metric tensor expand into? Since it describes general space-time, shouldn't it be more like a vector like

R = √(x^2+y^2+z^2)

Why even should we use tensors in relativity when we can just stick with vectors?

2) Are the equations all theoretical? Have they been proven? Can they calculate anything physical calculations like exactly to what angle or degree space and time are curved?

3) Why do all the equations and math attempt to look so confusing? I have been doing a lot of research on the equations recently, and I am deducing that theoretical physicists use redundant notations just to make everything seem too complex for an average person to understand?

Thank you!
