"Black Hole Sun" is a 1994 song by Chris Cornell of Soundgarden; the writer has said he's not sure himself exactly what the lyrics mean. The term "black hole" is used by astrophysicists to refer to an object with a gravitational field so strong that the escape velocity exceeds the speed of light. Our sun is actually too small to become a black hole; the minimum amount of mass required is somewhere between 150% and 300% of the sun's mass.

There are no Black Holes in the Sun.

Our sun has, instead, sunspots which are «dark spots» in the photosphere. They are caused by the Sun intense magnetic field activity, with an periodicity of nearly 11 years.

These «dark spots» are not only darker in visual astronomical observation, but they are around 1,000ºC cooler than the surrounding solar «surface» - the above mentioned photosphere.

By the way, astronomers expect the Sun to invert its magnetic polarity next December, 2013, at the end of the present 11 years solar magnetic activity cycle.

Our sun is not massive enough to have a black hole in its center, or to form one when it eventually dies and collapses. You may be thinking of the current belief that all or virtually all galaxies have massive black holes at their centers. This seems to be the case for our Milky Way and for other galaxies that we can observe closely enough.

There is no "black hole in the Sun". A black hole is an object separate from the Sun. Or perhaps you mean sunspots - they look dark, but they are not really holes, simply regions which are quite a bit cooler than their surroundings.

It seems that the closest known black hole is at a distance of about 3000 light-years from us. Or from the Sun.

Why does the sun's energy form a black hole?

The sun's energy has not formed a black hole.


Do black hole suck the sun?

In theory, yes, a black hole could suck up the sun.


Why is the sun considred a black hole?

First of all, our sun can not become a black hole, it is too small for that. However if a star is three times bigger than our sun, then yes it will become a black hole.


How big would the sun be if it was a black hole?

If the Sun were to collapse into a black hole, it would not grow significantly in size. The size of a black hole is determined by its mass, not its previous size as a star. The Sun would become a black hole with a radius of about 3 kilometers.


Does the sun travel around a black hole?

Yes, The sun and the solar system orbit the center of the galaxy where there is a black hole.


How fat is a black hole?

A black hole can have anywhere between a few Sun masses, and several billion Sun masses (the so-called "supermassive black holes"). The diameter of the event horizon, if that's what you mean, is directly proportional to the black hole's mass - in other words, more massive black holes have a larger diameter.


Will the sun become a black hole one day?

No. The sun does not have enough mass to become a black hole. When the sun dies it will become a white dwarf.


Can sun escape from a black hole?

No


Has a black hole ever been in hour galaxy?

I assume you mean "our galaxy". There is a supermassive black hole, with a mass that is about 4 million times the mass of our Sun, at the center of our galaxy.


Can the sun form a black hole and take earth to another galaxy If yes how I no why not?

No, the sun does not have enough mass to form a black hole. Even if it did, the sun's gravitational pull would not be strong enough to drag Earth into another galaxy. The sun will eventually evolve into a red giant and then a white dwarf, but it will not become a black hole.
