And then we have the time lag caused by the distances traveled by the light.

Well, the crab nebula supernova was visible in daylight (the "guest star" in ancient chinese records).  How far away was that?

Only about 7 light years IIRC.

I think if a star four light years away, like Alpha Centuari (closest star) went supernova, I think it would almost instantly create a nebula that would cover a good portion of the sky.... Delayed by four years of course.

I'm assuming a 1987A type explosion.

Truth or Sarcasm?

Truth.

He probly read ly (lightyears) instead of kly (kilo-lightyears).

Well, the RADIUS of the crab nebula is 6 ly, so if we were 6 light years from it, we'd be partially inside it (or it'd cover a good portion of the sky).
