Assume that the sun just died spontaneously (or disappeared) so it would be pitch black during the day and there would be no heat or solar energy whatsoever. How long would we last before we died?

If we had enough indoor greenhouses, we wouldn't have to die out.. well, not all of us. I'd bet that about 500,000,000 humans (being a vegetarian would be easier --> not having to feed your animals) could live off of the plants grown from artificial lighting.
The sun and the earth are about 8 light-minutes away, so everything would be dead shortly 8 minutes after the sun disappeared.

Yeah but think where all that electricity comes from. Will your electricity supply last for the rest of your life?
Another thing is HEAT. It is probably going to get to absolute zero if the sun goes out...
8 minutes after the sun went out, we would see it go out.
We would probably be at -200F within 24 hours, and at -400F within 48 hours.
So I would say less than one day.
some places dont see sun all year, and scientists survive there in huts

False. False. False!!!

This is right. The sun is not only our energy source, but our heat source as well. Unless we learned how to harvest the earth-core's heat, we have no other source and would soon be an inhabitable place.
Besides what was stated above... the Earth's orbit and all around us would change.

that would suck....
and we'd spend our last moments listening to nut jobs say the changing climate was our fault
We wouldn't necessarily lose all sources of heat and light.

What is 93 million divided by 186,000?
Why can't we make fire with matches?
Depends on how the sun died. If it was really gradual then life on earth like animals and plants would die off long before the sun "went out." If the sun turned into a black hole, earth would be sucked into it. But God wouldn't let either one happen because he loves us.

So the next logical question would be: if you saw the sun go out, would you shoot (or otherwise kill) yourself or choose to die by freezing to death?
i'd shoot everyone around me and use them for food and heat, etc.
(well, that excludes the hotties. i'd use them for body heat)

The upper atmosphere would cool off that rapidly, but I think it would be a little longer, probably about a week because of the heat energy stored in the surface of the Earth. And then considering all of the heat energy in the tropical oceans, and it could be possible that humans on tropical islands could survive much longer.
All of this assuming the Sun just goes out and doesn't turn into a black hole, in which case we'd absolutely be effed much sooner.

No, not really. If the sun's mass were magically converted into a black hole presumably located at the current center of the sun, it would still have the same gravitational pull on anything further away from it than the current diameter of the sun. In particular this includes the earth whose orbit would remain unchanged in this scenario.
I dunno but we should leave out a tip jar for the sun's services
