In any problem of Astronomy or Space the force is Gravity.
According to Wolfram Mathworld: http://mathworld.wolfram.com/SingularPoint.html
"A singular point of an algebraic curve is a point where the curve has "nasty" behavior such as a cusp or a point of self-intersection. " The graph of such a curve crosses itself at a point or cusp.
In astronomy there is only one singularity and it is called a black hole, and black holes are pure gravity. In the area around the black hole the largest gravitational force is concentrated and focused at one point, the exact center of the black hole. So everything near a black hole falls into it.
In astrophysics and orbital mechanics there are orbital points that are at a balance point. These locus points fit the algebraic definition of a singular point. If a object is let loose in our solar system then it either falls into the sun, falls into an orbit around the sun or falls into such a gravitational locus point (on an orbit around the sun). These points are called the Trojan points. They tend to collect matter like dust and asteroids. As the asteroids rotate around the sun they tend to collect near the Trojan points because they have such a small velocity and gravitational force. The gravitational forces of other bodies mainly Jupiter and the Sun exert enough pull on them to pull them toward the Trojan points. This is a slow process and it will take millions of years before all the asteroids are collected at the Trojan points. Some denser or larger asteroids may not move toward these Trojan points. This is the solution of the famous Three Body Problem or the N body problem. Worked out by the Finland-Swedish mathematician Karl Fritiof Sundman in 1912.
In the Earth Moon system there are 5 singular points or gravitational locus points. These points are called the Lagrange points. The gravity between the Sun, Earth, and Moon, as well as the orbital centripetal force, are balanced at these points. A space station positioned at one of these points will tend to remain stable at that point. The most popular point for such a station is either the L4 or L5 point, and the L5 Society has promoted building a space station there since 1975.
The solution for a multiple mass body problem is incredibly difficult. The multiple moons of Jupiter and Saturn create an incredible gravitational complexity of orbital mechanics for each system. We have known about the 12 Galilean moons of Jupiter for over 300 years. They have not collided yet and new moons (typically captured asteroids) may have been added or subtracted in Jupiter’s long lifespan. This creates an incomprehensional no-collisions singularities problem that cannot be regularised analytically.
Astronomers have found evidence of many planets rotating other stars. They do this by detecting the minute wobble in a star’s position, so only really big planets can be discovered. Any solar system with a large planet or another star orbiting it could have Trojan points.
There are many possible singular points in our solar system and in the other solar systems of the universe, and all of them are created by gravity.

I think you mean a singularity - which is so dense that gravity pulls in everything near it - including light

iam not well versed with astrophysical terms...but as i understand this singularity is the state in space time where all the laws of nature fail to exist....it occurs in conditions of infinite gravity in a black hole, at the time of bigbang etc......

Elohiym is plural style besides the undeniable fact that it would not advise a plurality of persons or personalities. that's the way .. in that element to say that, I advise, at the same time as human beings contained throughout the time of Moseh favor to say "i'm a prophet", he could say "i'm a prophet" or "we are prophet". we in this context would not advise plurality of man or woman. yet is a polite way in that element to say I. so the former testomony regulate the language with the present utterance. keep in mind that holy books in each faiths/each places could say the words of God by way of their languages/utterances .. keep in mind that maximum MCs in huge activities could say "we get exhilaration from" We yet no longer I .. besides the shown actuality that there is merely one guy status there .. We meant I
