Gravitational collapse

Hypernovas are the deaths of massive stars and the formation of a black hole. They are larger than supernovas and are believed to be the origin of long gamma ray bursts. This violent explosion happens in a matter of seconds, but produces more energy in those seconds than the sun produces in its entire 9 billion year lifespan. Not a lot was known about hypernovas until 2003 when a massive gamma ray burst reached earth. This was identified as a hypernova and photographed. In 1999 remnants of a…

within the past 200 years is Albert Einstein’s Theory of Relativity. This in fact plays small and major parts in the reason for many of the following happenings. 1. The Expanding Universe 2. The Big Bang Theory 3. Time Travel 4. Black Holes 5. Gravitational…

collapsed and become so dense that it creates a gravitational field strong enough that nothing, not even light, can escape. When a star dies it leaves behind a very dense remnant core. If the core’s mass is more than three times the mass of the sun, the force of gravity will then overpower the other forces, thus creating a black hole. It was in the 1700’s that John Michel and Pierre-Simon Laplace first considered the possibility of a gravitational field too strong for light to escape. Black…

molecular clouds collapses and reaches a certain point. These regions are usually extremely cold and contain carbon and hydrogen. However, not all materials from the clouds form stars. Some of the material can form planets, asteroids, comets, or remain as dust. There are different kinds of stars in space, including neutron stars, white dwarfs, and brown dwarfs. Neutron stars come from collapsed cores of stars. White dwarfs are stellar remnants that is mostly made up…

from it. White holes emerge in eternal black hole theory. In addition to a future black hole, Einstein equations solution has a white hole area in its past. However, this area is not available for black holes that have been created through gravitational collapse. There are no recognized physical procedures through which a white hole could be created. Just like black holes, white holes comprise properties such as, mass, angular momentum, and charge. They attract object same as other mass.…

what we think of when we hear the word “star” they begin as clusters of gas and dust. Eventually this cloud of gas and dust will form a dense portion somewhere within itself. This will in turn attract more and more gas and dust because of the gravitational attraction of the particles. As this dense portion grows increasingly more dense the temperature increases and begins to emit light initially as infrared and eventually in the visible spectrum. It is at this point that a star is born.…

When hydrogen is used up, helium begins to fuse to carbon and the larger element such as calcium and magnesium. Once the main hydrogen supply is used up the outer layers of the star begins to collapse inward toward the core. This process generates heat which temporarily counteracts gravity causing the outer layers of the star to expand. The star expands about one hundred times bigger than it was originally. What happens next in the star life…

The Big Bang Theory is the current theory of the origin of the universe that has largely been accepted by scientists, however it is not one hundred percent correct as modifications of the theory is continuously being developed as new discoveries, observations and calculations are being made. In the beginning in the universe, there was nothing, no space, no matter, no light, no time and no sound. Then there was a sudden explosion of energy which we now call the Big Bang. But there was no BANG…

explained that these two things oppose each other- the gravitational force will try to contract the star and the internal pressure will act outwards. When both of these are balanced out, the star will maintain its size and will neither expand nor collapse. However, if a star runs out of fuel, and therefore continues to lose energy from the surface, the gravity will be much stronger than the internal pressure which will result in the collapse of the star and will lead to the formation of the…

composed of electron-degenerate matter and are white in color. The have a solar mass of up to 1.4, beyond this point, beyond this point, the pressure being exerted by the individual atoms is not able to hold back the gravitational pressure pulling it together The star would collapse down to a more compact object, like a neutron star or a black hole.. White dwarves are very dense, their average density being about one million times denser than that of the sun. A single sugar cubed amount of white…
