The Sun will never burst and will not become a black hole. Stars end their lives in two different ways: those will mass around the mass of the Sun will end their lives in a gentle way, becoming a planetary nebula and leaving behind a remnant called "white dwarf". Stars much more massive than the Sun explode as a supernova leaving behind either a "neutron star" or a "black hole". So, do not worry about the Sun becoming a black hole.
Now, to answer your second question: If hypothetically the Sun suddenly becomes a black hole (which will not happen), then nothing will happen to the Earth. Black holes do not go about scooping up people and planets. However, as there will be no longer any sunlight, we will have trouble keeping warm.
However, note that we are not safe on Earth forever. In another 4.5 billion years (that is a long time), the Sun will expand into a "red giant" star and will come very close to the Earth's orbit. At that point, Earth will become so hot that there will no longer be any oceans and will probably be the end of life as we know it. However, that is way into the future and right now, there is more danger that we will cause our own destruction (by wars and pollution) than anything happening due to the Sun.
so the sun will become as big as antares destroy us and shrink into a tiny little star

As many above have said, no, our Sun will never become a black hole. When it runs out of *hydrogen* in its core the core will shrink and its outer layers will expand - the Sun will be a red giant. At this point Earth will be toast. But all this won't happen for another 5 billion years or so.
A star needs to be around 10 times more massive than our Sun to go supernova, and even more massive than that for there to be a black hole left over after the explosion (if there's not enough mass left over, a neutron star is left over). After our Sun does its red giant thing (and I'm leaving out some details here) it will shed its outer layers, leaving behind the core which will be called a white dwarf once it's exposed.

No...our sun has a much different fate.
As the sun starts to covert the last of it's hydrogen to helium it will then start to it will start to expand, the expansion of the sun will reach about to the orbit of Mars. The Sun will become a Red giant. Once all the Hydrogen is fused to helium it will then start to fuse helium into heavy metals at this point the sun will start a rapid shrinking. The sun will shrink to a star similar to the size of the earth and will become very hot turning into a white dwarf star (the second most common star found in out galaxy.) The sun at this point will also form a planetary nebula. When the sun collapsed it left a ring of dust and gas around it. The massive amounts of energy being released by the sun as it converts Helium to heavy metals caused this ring of gas to glow like a neon light bulb. When this last stage of furious fussing starts to subside the sun will become a brown dwarf as it cool (the most common type of star found in our galaxy.) it will remain this way until again the left over gases and metals converge to form a new star.

No. If I remember correctly, it will first turn into a red giant, and then shrink back down into a white dwarf. It is predicted this will happen 35 million years from now. The mass of the sun is just not great enough to become a black hole, or even a neutron star.

No, eventually the Sun will become a white dwarf. If I remember correctly, only stars of 3 solar masses or more can collapse into black holes.

No. Only stars which are much bigger than ours can collapse on themselves when they "die", become supernovae and have the remnant crash on itself to become a black hole. So there is no chance that our Sun will become a black hole.

No...sun is huge but not massive enough for that. For a star to convert into blackhole it requires huge mass decided by Chandreshkar limit. Our sun falls short of that limit.
However when sun do falls short of fuel (helium) it will expand and expand enough so that it will engulf our Earth. Sun is in middle of its lifespan. It will take millions of yrs for that to happen. Hope by that time we find a nice niche in some corner of universe.

Our sun will beome a red giant. It will never supernova or become a black hole.

I don't think that we will have to worry about that happening because the sun will most likely go into a super nova and engulf us. So we will die any way before we see any black hole.

As others have said, no, it won't. It will become a red giant (thus incinerating the planets around it), and shrink to a white dwarf. Our sun is currently what is known as a yellow dwarf (I believe).
