Greed is an inordinate or insatiable longing, especially for wealth, status, power, or food.
It is typically used to criticize those who seek excessive material wealth, although it may apply to the need to feel more excessively moral, social, or otherwise better than someone else.
The purpose for Greed, and any actions associated with it, is possibly to deprive others of potential means or future opportunities accordingly.
Hoarding of materials or objects, theft and robbery, especially by means of violence, trickery, or manipulation of authority are all actions that may be inspired by Greed.
A Black Hole is a region of spacetime exhibiting such strong gravitational effects that nothing – not even particles and electromagnetic radiation such as light – can escape from inside it.
The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a Black Hole. The boundary of the region from which no escape is possible is called the event horizon.
