"The big bang theory does not assume the end of the universe"..... i mean or i would say the disintegration of the universe, and of the countless cylce of destruction and formation of the universe and its universal phenomena.
The question that is tackled here is how the universe and everything in it was created and the most accepted theory was the Big Bang theory.However, it does ot stop there. There are new theories of the eternity of the universe and that lays down the foundation of the Big bang Theory. As this theory says that about 15 billion years ago a tremendous explosion started the expansion of the universe. At the point of this event all of the matter and energy of space was contained at one point. What exisisted prior to this event is completely unknown and is a matter of pure speculation. This occurance was not a conventional explosion but rather an event filling all of space with all of the particles of the embryonic universe rushing away from each other. The Big Bang actually consisted of an explosion of space within itself unlike an explosion of a bomb were fragments are thrown outward. The galaxies were not all clumped together, but rather the Big Bang lay the foundations for the universe.
The origin of the Big Bang theory can be credited to Edwin Hubble. Hubble made the observation that the universe is continuously expanding. He discovered that a galaxys velocity is proportional to its distance. Galaxies that are twice as far from us move twice as fast. Another consequence is that the universe is expanding in every direction. This observation means that it has taken every galaxy the same amount of time to move from a common starting position to its current position. Just as the Big Bang provided for the foundation of the universe, Hubbles observations provided for the foundation of the Big Bang theory.
Since the Big Bang, the universe has been continuously expanding and, thus, there has been more and more distance between clusters of galaxies. This phenomenon of galaxies moving farther away from each other is known as the red shift. As light from distant galaxies approach earth there is an increase of space between earth and the galaxy, which leads to wavelengths being stretched.
In addition to the understanding of the velocity of galaxies emanating from a single point, there is further evidence for the Big Bang. In 1964, two astronomers, Arno Penzias and Robert Wilson, in an attempt to detect microwaves from outer space, inadvertently discovered a noise of extraterrestrial origin. The noise did not seem to emanate from one location but instead, it came from all directions at once. It became obvious that what they heard was radiation from the farthest reaches of the universe which had been left over from the Big Bang. This discovery of the radioactive aftermath of the initial explosion lent much credence to the Big Bang theory.
..."..predicts that the universe is expanding. Does Buddhism make that prediction.
It is no longer a prediction because the Universe,as Buddhism says, has always and always been. The Buddhist doctrine of "Impermanence" that all things, all phenomena(universe) are undergoing constant change. Life, nature and society- the entire universe, never cease to change for even a single moment in time. In addition to the understanding of impermanence, the interrelatedness of all things. The universe and everything in it are in flux, arising and ceasing, appearing and disappearing, in an unending cycle of change conditioned by the law of causation. All things are subject to the law of cause and effect, and consequently nothing can exist independently of other things. This Buddhistic concept of causation is also known as "dependent origination." Shakyamuni awakened to the eternal law of life that permeates the universe, the mystic aspect of life in which all things in the universe interrelate and influence one another in an unending cycle of birth(formation) and death (destruction).
