Gravitational singularity

Initially, there where a number of ways to get round the conclusion, that there was a singularity of infinite density in the past. There was a comment, which suggested that if one, where to make modifications to the law of gravity, i.e. allow gravity to become repulsive. The idea was that, as the galaxies moved apart, new galaxies were formed

universe. The big bang theory is an effort to explain what happened during and after that moment. According to the standard theory, our universe sprang into existence as "singularity" around 13.7 billion years ago. What is a "singularity" and where does it come from? Well, to be honest, we don't know for sure. Singularities are zones which defy our current understanding of physics. They are thought

Black Holes A black hole is a region of spacetime and it has strong gravitational that affects nothing. Nothing can escape from inside it such as particles nor light radiation. General relativity predicts that a compact mass can deform spacetime to form a black hole. The point of no escape is called the event horizon. The event horizon has an enormous affect on the fate and circumference of an object crossing it. Black holes reflect no light. When it meets a star it consumes it and turns into a colorful

According to the general relativity theory, a sufficiently compact mass has the capacity to deform spacetime thereby forming what is commonly known as a black hole, a point around which the gravitational force is too strong. Imagine a giant building, a skyscraper for example, being compacted and compressed to the size of a Rubik’s cube. This happens to the massive dying star at the end of its life. For nearly 200 years now, theorists have postulated the existence of black holes and now there is

My interests in physics surround the central theme of developing a unified description of the fundamental laws of the universe that is based on underlying symmetries and devoid of free, dimensionless parameters. Superstring theories are one class of theory that endeavours to provide such a description. My graduate research has included projects in both theoretical developments using type IIB supergravity (SUGRA), as well as its application via the AdS/CFT correspondence. A string theory description

"A singularity is a place on either space or time at which some quantity becomes infinite (without an end). Such a place is found in a black hole, the final stage of a collapsed star, where the gravitational field has infinite strength." Singularity could exist in the space - time in a real universe is what Penrose proved. (notable biographies.com) Hawking used the work of both Penrose and Albert Einstein to demonstrate that our universe has its origins in a singularity. In the universe

then it will become a new star and start the process over again. After that, gravity will drag you toward the singularity at the speed of light and ultimately spaghettify you. Gravity's strength is determined by the mass of the object its pulling and then the pulling strength gets greater. This also means that you would be stretched to fast if you happened to enter a black holes gravitational pull. Closer to the center, gravity is even stronger. If you were caught by the pull of a black hole, you would

Although once foreign giants to man, stars live some of the most explosive lives possible. Over billions of years, the violent development of stars from conception to death is one that had perplexed mankind for a while. Though as we formed a better understanding of how they develop, humans have learned that these stellar orbs directly influence the formation of, or death of objects in the universe. Stars are phenomenal objects in our universe that are instrumental to its development. These celestial

evolved from the standard theory. The standard theory says that the universe came into existence as “singularity” around 13.7 billion years ago (Big Bang Theory). Singularities are believed to have originated at the heart of black holes. If one can see a black hole, one is too close. Therefore will be sucked into the black hole. Due to the powerful force of the black hole’s gravitational pull. A singularity is defined as interminably small in size, immensely hot in temperature and extremely dense. Those

Black holes are strange because we can not see them because they have such a strong gravitational pull light can 't escape from. They can rip anything apart. Black Holes form when a star dies and collapses in on itself. They are usually relatively small and really dense. Rather, it is a great amount of matter packed into a very small area - think of a star ten times more massive than the Sun squeezed into a sphere approximately the diameter of New York City. In the milky way their are a few hundred
