The idea could be considered as madness but others may say THIS IS PHYICS!  After the giant nebula has started to converge it forms a Protostar, this Protostar is halfway between a nebula and a star. Eventually it gets to a point where it cant contract any more gas and the tremendous pressure starts to cause tremendous hear, and thus nuclear fusion begins, true story. 
Astronomy 10 Chapter 11 1. Both used to be normal stars but the white dwarf ran out of hydrogen, they are both subjected to gravitational theories. A Neutron star is a fluid of neutrons, as hot at its surface as the inside of the sun and has a greater magnetic field. 3. Because its density is so high, neutrons spin in the same way that electrons do so must obey the Pauli Exclusion Principle.
In addition, entering a black hole would not only take thousands of years to occur, according to “Spaghetti theory” the gravity would be so intense as you neared the center of the black hole, your body would be stretched out into a thin strip of organic matter. Not to mention that this is all assuming that black holes are connected to other black holes in some separate universe and at a different time. Speaking of which, since time is relative, Spock going into the black hole a few seconds after The Narada, and coming out after it has been 25 years is quite plausible. So both the timeframe and how this scene was portrayed have little scientific background and is most likely
Terms to Know: Scientific Revolution and Enlightenment Scientific Revolution- a period when new ideas in physics, astronomy, biology, human anatomy, chemistry, and other sciences led to a rejection of doctrines that had prevailed starting in Ancient Greece and continuing through the Middle Ages. Copernicus, heliocentric view- He proposed a model of the solar system in which the planets orbit in perfect circles around the sun; his work ultimately led to rejection of the established geocentric cosmology. Tycho Brahe- a Danish astronomer whose observations of the planets provided the basis for Kepler's laws of planetary motion. Johannes Kepler- was a German mathematician, astronomer and astrologer, and key figure in the 17th century scientific revolution. 3 laws of planetary motion- a Danish astronomer whose observations of the planets provided the basis for Kepler's laws of planetary motion.
These potential causes can be grouped together to be dismissed, having a similar end result. Nuclear war and the less likely, but still possible, gamma ray burst can be easily dismissed due to the lack of one key condition. A gamma ray burst is a type of explosion caused by a star nearing supernova. Its explosion sends a massive amount of radiation and energy in a very compact beam that could easily bake the planet with enough radiation that nearly all forms of complex life, humans included, would perish quickly. The resulting nuclear winter would occur causing the aforementioned minor ice age event, but it is the lack of radiation that prevents this from being a possible answer.
8. Why was the formation of planets such as Jupiter and Saturn more like the development of the Sun then like the development of the terrestrial planets? Saturn and Jupiter are mainly made of gases like the Sun instead of solids like the other planets.

When the source of hydrogen in the Universe is exhausted, all the stars will burn out and die. 3. The gravity of the Universe may become so great that it will bring all matter in the Universe back together and the Universe will collapses into black holes. 4. It is, therefore, true to say that everything that exists in the Universe is not permanent.
The four largest of these were seen by Galileo when he made one of the first telescopes. The way they moved round the planet convinced him that the old idea, that everything moves round the Earth, must be wrong. The following was kindly contributed by Russell Odell The sun contains 99.9 percent of the mass in the solar system. The remaining 0.1 percent make up the other planets and their moons, and Jupiter took most of that mass. If Jupiter were a shell, all the other planets and their moons could fit inside with room to spare.
But when they came to one that was about half the size of Pluto that’s when they began to question their though of Pluto being a planet. They named the large Kuiper Belt object (KBO) Quaoar after the god who created the Native American Tongva tribe. Quaoar actually had a more planet like orbit then Pluto does. Which also gives astronomers a reason to question if Pluto really is a planet. People 1st started to actually look into the idea of Pluto not being a planet in 1998 by the International Astronomical Union also known as the IAU.
This does not enhance their capacity to split, but it does have an important bearing on their capacity to facilitate an explosion. When a U-235 atom splits, it gives off energy in the form of heat and Gamma radiation, which is the most powerful form of radioactivity and the most lethal. When this reaction occurs, the split atom will also give off two or three of its "spare" neutrons, which are not needed to make either of the parts after splitting. These spare neutrons fly out with sufficient force to split other atoms they come in contact with. In theory, it is necessary to split only one
