Suppose you take a picture of a certain star-field as a reference. Now, imagine a black hole comes between you and the center of the same star-field, and the black hole is relatively near to you.

Describe how the appearance of the star-field might change.

(Hint - one of the APODimages contains the clue).

The black-holes are more darker then we could have ever think of, as the black hole's body is considered to be much darker and posses the heavy gravitational field inside it. As the whole mass, m of the black whole is very unknown till date, but the scientists considers the black whole to be a large mass of celestial entities which no physical body can escape. But, it captures all of the starlight and other masses into its system.

The star light is seen more bending into the edges of the black wholes, as there are much of the energy,E been captured around the black-holes edges. Along, with which the if the black whole is relatively near to us then we would consider some precautions to take before things get worsen up, as it can also take things up into itself.(along with the consumption of starlight into the black hole). As, the starlight is seen been consumed inside the greater mass,m of the black hole.And the energy,E is sort of a perpendicular to the actual position of the energy ring of the black hole.

3. i would say one, but one is not prime nor composite.
