It is exploding all the time. but if u are referring to a super nova it will never happen, our sun isn't big enough.
and as for the time it takes to notice, the limitation is the speed of light, no signal can take less than 8 min traveling
from our sun to earth, so our sensors wouldn't know before we did anyway.
just my 2 cents
NASA already has an estimation as to when the Sun will become a red giant, which would engulf Earth.
It basically is a super slow and less intense version of a supernova.
If NASA is around that time, I'm sure they can predict exactly what time the "Red Giant Event" will begin.
In which case we would know when it starts beforehand, and 8 minutes after it started we would see the effects.
In any case, this is all besides the point.
The point I was making was that although anything we witness happening to the Sun is 8 minutes after it actually occurred, for "all intensive purposes" it actually is happening instantaneously because to us the event doesn't occur until the light from the event hits us.Edited by kennyparker1337 - 2/21/13 at 10:29am
