Our galaxy is rotating and is charged therefore the choice for the metric is the Kerr-Newman Metric.(adsbygoogle = window.adsbygoogle || []).push({});

I want to solve for the Kerr-Newman Metric Tensor.

There are a few questions.

1-What is the value for Q in the equation:

##r_Q^2=\frac{Q^2*G}{4*\pi*\epsilon_0*c^4}##

where

##G=6.674E-20 \frac{km^3}{kg*s^2}##

##c=299792.458 \frac{km}{s}##

##\epsilon_0=8.8541878E-9 \frac{F}{km}##

Charge of an Electron ##e=1.602E-19 C## if needed for Q?

2-How do you calculate and position the Angular Momentum of the Milky Way Galaxy?

##J=r \times (m*v)## I know r and v are just part of a list not vectors.

##a=\frac{J}{M*c}##
