Our sun will never be a supernova (explode).
It's not big enough. Only stars with a mass beyond a certain limit (about 2.4 times our sun's mass) can ever go supernova and explode.
Stars with a mass like our sun's become red giants instead -- as they run out of hydrogen and then helium to fuse, they start to swell up to truly huge sizes -- large enough for the outer atmosphere of the sun to go well beyond earth's orbit. Once that swelling occurs and large amounts of the sun's outer layers are "puffed" gently off (not in any kind of explosion), as fusion halts entirely in the sun's core it will slowly shrink back down to a size about 1/10th what it is now, and quietly give off what remains of its heat energy for another few million years.
No explosion. No supernova. Just a slow burn :)

Yes. The light from the explosion would arrive in about eight minutes (since the earth is eight light-minutes from the sun), but the material of the sun would take longer to reach the earth. According to the paper cited, the average propagation speed of a solar flare (aka 'corona mass ejection') for the events they observed were at most 1,400 km/sec. So, since the Earth is 149 668 992 km from the sun, it will take 106 906 seconds for a flare to reach the Earth, or 29 hours. So, we'd be blind for about a day before the Earth was hit by the explosion proper.
Man, that's a downer.

Remind me to ask this question again in 5 billion years from now. Don't think my mobile phone's diary goes that far though...
You would probably fry to a crisp before you even got the chance to go blind. So you die first, the rest doesn't matter anymore, and then the Earth is scorched, venus half swollowed by the sun and mercury completely eaten. And the sun nibbling on Earth's orbit.
I'd suggest a mass evacuation to Pluto.

The sunlight isn't the right length of massive call to really explode, yet for the sake of argument, lets anticipate that it truly is. because the daylight is 8 mild minutes away, it truly is bodily no longer a threat for us to understand any change contained in the daylight for 8 minutes after it occurs. the mild or different radiation or debris from the explosion ought to nevertheless be on its way in route of us. until eventually that element has exceeded, so some distance as we are in touch the daylight has no longer exploded and we are able to proceed orbiting round it, getting a tan or inspite of. Even the daylight's gravity retains on for that element. hence, we truly would not die in the previous the 8 minutes is going with assistance from, except we were given run over with assistance from a truck or something. We in all likelihood ought to die very quickly afterwards, notwithstanding.

I believe the Sun won't just explode suddenly. It will slowly expand out into a supernova then become a white dwarf, and we will all just die a terribly death, that is if our technology is not good enough to go to other worlds to save ourselves.
If there is a problem with my answer (logic or facts wise) please correct me.

If you were looking at it when the information reached here,it would not make much difference but you eyes would stop working pretty fast.
So would you!

supposing it did, it would all happen in a flash, you'd be instantly vaporized

not really. basically, all life on earth would vaporize.
