Mmmm... z = 0 = z = sqrt(x^2 + y^2 + z^2 - t^2) Zero can kind of serve many masters.

- JadeNB 8y ago> z = 0 = z = sqrt(x^2 + y^2 + z^2 - t^2) I'm not sure what this is meant to signify, but surely you don't want the same `z` on both sides of the last equality?
- DougMerritt 8y agoright, typo, the left side is supposed to be a symbol for space-time interval, not z again.
