What else can I help you with?
Is it true if a black hole swallows a supernova nothing will happen?
This is NOT true. Black holes are formed when massive stars explode in supernovas, blowing much of the star into space and crushing the core into a black hole. One of the things that WILL happen is a massive pulse of x-rays and gamma rays.
How does a black hole give off light?
The light that the Black Hole sucks up ends up in another part of the Universe . (Or at least that's what the scientists hypothesis. A black hole is not a portal, it is a star core that uses its immense gravity to pull in anything nearby. When something is pulled in, it's traped in the center and crushed under the intense gravity.
How many Planets in black hole?
There is simply no way of knowing this. Once matter is consumed into a black hole, it is converted into gravitational energy; a black hole's contents cannot be dissected and catalogued. However, according to an idea called the holographic principle, it may be possible for all the information contained within a black hole is encoded on its surface. If this proves to be true, then it might be possible to determine everything that has been sucked into the black hole.
Black body radiation of the emission o light from metal surfaces false or true?
This is false. Most metal surfaces are shiny and reflective. These reflect light away from the surface and absorb very little heat/light. An example of something that absorbs light/heat is black soot and something that doesn't absorb either would be glass.
Is it true a black hole is no more massive that the star from which it was formed?
For a stellar black hole, yes. Mass cannot be created or destroyed. Generally a black hole will be less massive than the star from which it formed, as much of the star's mass gets blasted when the star dies in a supernova. A black hole can gain mass over time as matter falls into it.
What happens in a black hole that makes the saying "what happens in a black hole stays in a black hole" true?
In a black hole, gravity is so strong that nothing, not even light, can escape. This means that whatever goes into a black hole is trapped inside forever, making the saying "what happens in a black hole stays in a black hole" true.
Is it true that black hole is black so iit absorbs light and moon is white in colour so it reflect light?
Let's clarify that the "blackness" of a black hole is of an entirely different type than that of black surfaces in general. A black surface will absorb light, but it will also emit light according to its temperature. A black hole will absorb light, but will not emit anything, since gravity basically lets nothing escape (except for an insignificant amount of Hawking radiation). In general, white objects reflect more light than black objects. Please note that the Moon looks fairly bright if you look at it at night; but actually, its albedo - the amount of light it reflects - is only somewhere around 5%.
What is black made out of?
A object appears black when it reflects or emits no visible light. True black is very uncommon because almost no substance can completely absorb light. http://en.wikipedia.org/wiki/Black

Are black hole common?
A black hole? well scientist are not sure. Black holes is a theory, not proving to be true. But there could be.
If you are pregnant can you stiil escape from a black hole?
no! that is not true because perganacy has nothing to do with space or a black hole
Is it true that there is a black hole?
No, that is not true. There are millions upon millions of black holes, not just one.
Does an opaque object reflect the light it does not absorb?
true
What is true about the light reaction?
photosynthesis begins when pigments in photosystem i absorb light.
Do an opaque object reflects the light that it does not absorb?
true
Is it true that smooth objects absorb more light than rough objects?
No, smooth objects actually reflect more light than rough objects. Rough surfaces scatter light in multiple directions, reducing the amount of light absorbed. Smooth surfaces are more likely to absorb and reflect light in a more concentrated manner.
Is there color black in nature?
Black is the absence of all colour, so if you look into a small, dark hole, and exclude all light, you will see true black.
