A Big Bang conundrum

Jaakko Kurhi The reason the Milky Way isn't collapsing in on itself is for the same reason that the planets stay in orbit around the Sun, and don't fall in: they have sufficient lateral velocity to miss the Sun as they fall towards it, otherwise known as centrifugal force. The stars in the Milky Way fall towards the centre, but keep missing it, and therefore stay in orbit around it. If any of these stars were to lose a sufficient amount of their lateral velocity, then they would fall towards the center. And it's the same reason why nearby galaxies fall towards each other. If they have sufficient lateral velocity, then they will fall towards each other and keep missing, therefore they will enter into orbit around each other. If the galaxies don't have enough lateral velocity, then they will fall towards each other and hit each other, and combine together. BTW, centrifugal force is not a real force, it's really the reactionary force to the force of gravity. As Newton's Laws said, every action has an equal and opposite reaction, centrifugal force is the reaction to gravity. Yousuf Khan |

Yet again, you're starting to make up your own terminology. First you start off by calling the Earth and Moon, stars?!? And now it seems your definition of a Recycling Universe is simply gases coalescing into stars within the galaxies, over subsequent generations. Well, yes, the gases inside a galaxy get recycled into new stars, but that's nothing like a recyling universe which means a universe that goes from Big Bang, to Big Crunch, and then back again, over and over again. The whole thing expands and collapses under its own energy. If you want to get taken seriously, you can't start making up your own terminology at random. These terms have well-established meanings.

No. For the action of the Earth pulling and accelerating the Moon, the reaction is the Moon pulling and accelerating the Earth. The "centrifugal" pseudo-force is what the Earth-facing Lunatic thinks must be supporting the Earth against the gravity field that he feels more strongly. The Lunatic, of course, does not perceive the monthly rotation, except by seeing the Stars move across his sky and the Earth spinning daily. -- (c) John Stockton, nr London, UK. Mail via homepage.

Okay, you're right, that was David Levy in the thread "Star Age Measurements". My apologies. In the case, my post; April 29th 13 did not make it clear, concerning my view of recycling universe; I try to clarify; its based on the concept where the universal matter is in the natural cooling cycle, from the hot events to the very absolute zero temperature state, where the mass of the matter only exists. This postulation is against the current scientific view, because of the application of laws of the thermodynamics, quantum mechanics and equation of E=mc squared. Conclude, that the matter cannot penetrate into the true 0K environment. My disagreement is based on the fact that none of the above components are applicable to explain the behavior of sub atomic particles at very lowest energy and temperature. The reason that absolute zero is not possible is because the Universe is a closed system, and all of the heat that was ever created is still located within the Universe, it cannot escape to the outside, as there is no outside beyond the Universe. The only way that the Universe is cooling down is because it is expanding. By the laws of thermodynamics, expansion causes cooling, while compression causes heating up. Subatomic particles at their lowest energy level still have movement. This movement is due to the quantum uncertainty principle, which states that you can't tell both a particle's speed and its position beyond a certain level of accuracy because the particles exist as a cloud of probabilities rather than a definite and discrete single particle. In other words they are just moving because they can't exist in one place for very long. Yousuf Khan |

a closed system, and all of the heat that was ever created is still located within the Universe, it cannot escape to the outside, as there is no outside beyond the Universe.” The quest for the cooling of subatomic particle matter into the energy-less state is still an unresolved case. The motion within the subatomic particle system indicates the use of energy, and the output of the measurable heat further confirms the use of energy. Because of the energy used for work that generates heat is an expendable type, therefore, the source for energy stored within the system depletes and eventually runs out. The space vacuum, nothingness or so called ‘place’ where the universe exists has no temperature, it’s the existing matter in that space that radiates heat. Hence, in the deep space, heat rays can be too far apart to keep the mass of the particle matter from cooling and reaching the absolute zero environment. So, for the bottom line, analyzing, how the subatomic particle system functions, using uncertainty principle and its resulting probabilities, cannot conclude for absolute certainty, that reaching the motion-less absolute zero is impossible. In case of the fast expanding BB. universe, where particles of matter are constantly growing further apart, resulting the reduced density of radiated heat. Hence, fewer of the heat rays are available to land on the isolated particles of matter, therefore, more of these cooling particles will slip to below the mean space temperature and further advance towards the motion-less state of the matter. So, in the inflating BB. Model, ‘if you will’, the cooling process accelerates as the inflation continues. Hence, eventually the matter will convert to mass only existence, and to potential ingredients for the recycling BB. events. However, it’s problematic to think of operations of the fast inflating universe which makeup is less than 10% of the matter, and the balance is the dark matter. Afterthought; perhaps a simple and naturally functioning recycling universe, which is less problematic and more logical solution. After all, isn’t the quantum mechanics designed as a numerical replacement for the logical thinking? Jaakko Kurhi |

Way galaxy moved 13 billion light years away from the location of the young and small universe. “No. The Milky Way moved at a speed of 300 km/sec over most of its history. How far light traveled, and how long the Milky Way aged are two very different things.” So, how can a slow-moving Milky Way be as an observer of the 13 billion years-old light, if both the light rays and the Milky Way originates from the same small entity? , The moving speed of the Milky Way is not fast enough to place it to the right position for observing that old light. Dear David, because of your communicating format is not very informative, perhaps a related link to this subject, that explains, how a fast inflating universe can be observed from the point of view of the slow-moving Milky Way, should be truly helpful.
