if it was twice as massive, earth probably have burned, noone would be here, and surviving would be a 1 out of 100,000

How long would main sequence star last if twice as massive as the sun?
A star with a mass of 2solar masses, 2times the mass of the sun, would have a main-sequence stage of half the life of a star with the mass of our sun. More massive stars die faster, less massive stars live longer and therefore have longer main-sequence stages.
If the Sun were replaced by a star with twice as much mass what would happen to the gravitational force between Earth and the Sun?
If the sun was replaced by a star with twice as much mass the gravitational force would be unbalanced and the new sun would burn the earth because if the gravitational force cannot hold than the sun would plummet towards the earth and burn it.
What would happen if you nuked the sun?
nothing would happen, the sun is constantly going through nuclear reactions
What would happen if the moon was on the left and the sun is on the right?
Nothing would happen if the moon was on the left and the sun on the right. The moon and sun are often on different sides of the earth.
If a star is twice as massive as the sun how will its lifespan compare?
The life expectancy of a star (E) depends on its mass (M), roughly following the model of E = M-2.5. For a star with a mass twice that of our sun (enter 2 in place of `M`), then the lifespan will give 0.177. Our suns lifespan is around 10 billion years, so this would equate to 1.77 billion years.
If the sun had twice as much diameter and mass what would happen to the gravitational force between Earth and the Sun?
Double

Why the sun didn't move around the earth?
Because the Sun is more massive than the Earth. If the Earth was more massive than the Sun, then it would.
What will happen if the sun gone supernova?
The Sun won't go supernova (it isn't massive enough) so the question has no real answer!

What would happen to the earth's pull on the sun if the sun was twice as large as it is now?
The earth's pull on the sun is VERY small. If the earth was to suddenly... disappear, like with a completely impossible (but it would be cool! Or at least if I wasn't on it...) dimension warp, I don't think the sun would be too terribly affected. That's normally. If the sun was twice as big as it is now (DUDE! That's HUGE! Do you KNOW how big the sun is compared to the planet Earth? 0_0), I doubt the earth's gravitational pull would have any affect on the ginormous sun at all.
What will happen if the sun explode?
We'd be totally screwed. ______________________ Seriously, it would ruin our whole day. It would vaporize our planet and turn us all into steamy goo. Good thing for us that the Sun is too small to explode!
What was the weirdest thing you heard would happen on December 21st?
I heard the sun would shoot a massive beam through all of the planets in line like a grapple, then yank them all in at once.
What would happen to the Earth if the sun swallowed mercury and became much more massive?
Mercury is much smaller than the sun, so the effect would probably be negligible. Plus, that's not likely to happen any time in the next 5 to 7 billion years. At the end of its stellar evolution, when the sun becomes a red giant, the sun will expand out as far as Mars, consuming all the inner planets, including Earth. This will not happen for billions of years.

Is sirius a young star?
Since it has about twice the mass of the Sun, you can expect it to be relatively young. Such massive stars burn out fairly quickly (for a star).
How bright would the sun look if you were on a planet twice as close to the sun?
4 times brighter.
