My, my, I have satisfied myself that the Schwarzschild metric is good inside an event horizon, if we just flip the sign of time and radial terms. Is this possibly a BIG DEAL? It would change the oft-repeated chant, “timelike intervals are spacelike, and vice versa”. I am free to do this !!! Math constraints stated involve the DET, with product of g_00 and g_11. I can do this and match forms with the sign change, so a plot of S goes up the pole and comes down … not from the basement back up !!! I correct myself to say the plot of 1/S, since S goes to zero !!! I have always hated when physicists like Xerxes on Advanced Physics forum, came back at me by parroting this chant. So what??? This could be a VERY GOOD DAY.
