But the blast that we see from Praxis is a two dimensional ‘disk’ which emanates outwards like the ripples in an ocean when a pebble is dropped in. these shockwaves moved only on a two dimensional plane, not a three dimensional one. The explosion only travelled along one axis, Surely if this burst of energy had hit a planet such as Qo’noS it would have caused even more apocalyptical destruction than we were told? The only explanation that I can think of is quite simply that the planet Qo’noS was just *slightly* below this two dimensional blast wave, therefore managing to avoid the brunt of the blast. The Klingon homeworld must have been hit by a ‘smaller’ blast. I made a picture of how it happened in the film, but of course this is not to scale: Speaking of scale, do we know how far exactly Praxis is from the Klingon homeworld? Praxis may not even be in a close orbit of the planet. Is it also possible that Praxis could have been a ‘Klingon moon’ orbiting another Klingon planet, or was it specified that it was a moon of the planet Qo’noS explicitly? A blast on the moon of a planet nearby to the Klingon homeworld of a scale as seen in Star Trek VI could still have resulted in damage to Qo’noS and it’s ecosystem, just like the blast damaged the Excelsior which was also *very* far away.
