Big Bang and the expansion koh of the universe | Lists of the white box
The most important event in the history of the universe lasts only fractions of a second. koh Billion years after its creation scientists seek to trace step by step the same occurrence tremendous, with beautiful theories fall one by one, and place each of them popping koh up another three, and Hsbrihn perfectly fine.
When bubonic plague in 1666, closed the University of Cambridge where he studied Isaac Newton, and students were sent home. Newton returned to his native village and was patrolling his fields koh idle. One day there was a case a toddler and seemingly insignificant, there is ultimately up to the surface science without recognition. Supposedly, and this may be just a legend, lay Newton under an apple tree when suddenly dropped fruit and fell on his head. Ostensibly, this is normal, everyday, because inherently apples koh falling from trees sometime. But Newton is not the man to witness such an event and would pass him. Illustrious scientist later, koh he wondered why the apple falls, and whether the moon may fall, until he came to the conclusion that this is in fact illustrate koh the general rule that controls nature, which is the law of gravity makes bodies take together.
Newton realized with correspondence with the Reverend Richard Bentley (Richard Bentley) in 1692-3, that according to the theory of gravity, if the universe is limited in scale, should stars pull each other to collide them at night of nights. If the universe infinite koh in magnitude, then the gravity acting on the stars also is infinite, so the stars would rip apart portions to crumble to dust. Namely, whether koh the universe is finite or infinite, or whether, he is dynamic. Know Newton, the universe is static, and it was clear that there was no possibility that planets remain motionless in the vast space, whether it is limited in scale. To resolve the nagging issue is imagined universe infinite symmetric space which any body therein drawn equally in all directions. But Newton realized after a while that the universe gave his soul would not be stable, and that in fact the smallest disturbance will upset the balance of gravitational equilibrium. For example, a comet passes through the solar system will increase once the density of each part of the space through which it passes, and will attract more material at those districts, thus begin the process of complete koh collapse. To solve the problem, Newton argued that intervention Hmtrst occasionally goes the heavenly bodies apart.
Newton also thought about the more mundane explanation, claiming that the stars might fall on it like the apple fell down from the tree, because koh the stars that infinite numbers, uniformly distributed in the infinite, so there is a central point in which they can fall. What was the number of stars in the inherently limited, and the space itself was bounded in any boundaries, then according to Newton, all the stars were falling koh into a point located at the center. However, if Newton was evacuated to calculate it would find, of course, that the infinite space which is the center point, since each and every point is surrounded by an infinite number of stars from all sides.
Other mathematicians have calculated koh it themselves, and concluded that if the Newtonian gravitational theory is correct, it is impossible that space will be fixed. They of course never imagined the latter, the space variable, while the theory of gravity is that that is not true. Thus, modification to Newton's theory, according to which gravity has become, despite being a regular distances traction, even repulsion force very large distances. Being able to tell everyone that the planets koh are falling koh over each other and in fact are found in balance - weight, because the forces of attraction between nearby stars are balanced by repulsive forces koh of distant stars.
Until the early 20th century there were no astronomical evidence regarding the spread or contraction of the universe, and Albert Einstein had no doubt that the universe must be static, and that the stars keep fixed position in space - time. He never thought of another koh option, and certainly not unique gravitationally dense and infinitely koh small, would constitute an insurmountable barrier to human genius, and it will be impossible to work out what happened to her. Maybe because it missed Einstein prediction for expansion of the universe, and possibly because too clung Mach hypothesis in the material behavior.
Once published general relativity equations, and is solved first by Karl Schwarzschild in 1916, Einstein realized that it is but natural that the theory of gravity will allow to investigate theoretically koh the universe. A year later figured out that the the structure, thus brought into the science of modern cosmology. Einstein was able to develop a formula for the radius of the universe, and found that there is an inverse relationship between him and the square root of the average density of matter in the entire universe. However, Einstein having trouble acute derived from the theory of general relativity. Since the distances between the stars are tremendous and the pressure in the universe is zero, then the galaxies bound to crash. Since he could not find a stable solution Lmswaotih, they added 'cosmological constant' of the order the inverse square of the radius of the universe and stated that in nature there is a power anti - gravity, which is itself an element fabric of space - time itself. Because of this power has the space - time tendency to spread, and this trend continued offsets resulting gravity of any substance is found. Einstein accepted model of the universe where stars keep the spatial structure of fixed and moving only at the time (the average density of matter does not change with time), while space is indeed koh limitless, but it is not infinite but finite and closed like a ball - but he was wrong.
Einstein conceived the universe was not stable koh in principle. According to the solution of static, cosmological constant balance of just the force of gravity, but if it occurs minimal increase in density at some point, will increase continued gravitational interactions between the planets and increases the strength of the balance sheet that represented by the act of rejection of the cosmological constant, then you will begin to spasm, which will increase the density. This will increase again by gravity, and the contraction will continue until complete collapse. The cosmological constant is independent of the material influence, could prevent such collapse after it began. However, if the equilibrium condition
