@ Captain Kal
I wasn't thinking of the entanglement nervous system from the point of it being another power (speed based or otherwise), just an organic evolutionary enhancement to allow muscles powerful enough to go beyond 1/12 lightspeed to attain their potential. But yes, barring special enhancements like that, I agree with your calculations Captain, pretty cool
. Oh yeah, I've just been thinking on a possible organic reason for heat vision and all I can come up with off the top of my head is bio luminescence in his irises (due to the whole color thing, infrared is a "color" afterall
) or retinas, any thoughts?
@ManSinha
The speed of light is about 877,606 times the speed of sound. No cannon explanation I can think of for Superman's speed increase like that, I'd just go with the Mongul's son explanation of Superman removing his mental blocks, and yes I do believe DC is putting him back to his silver age power levels. I read a quote from a writer stating the same thing a few months ago, I think it was in a Wizard magazine, not sure though.
