thanks my issue has been fixed.

Hello, i live in the US and decided to get this book off of amazon i was wondering if anyone has read, or atleast skimmed (its pretty big) through it and would mind telling me if its a good buy(although if it isnt, its a little late now :-p). also, I am pretty new to most of the theories. all...

The neighborhood of an event includes points that are timelike, null, and spacelike separated from it; the light cone does not bound the neighborhood. The topology of spacetime is still ##R^4## even though the metric on it is not the one induced by that topology. Thanks
