big bang theory Essay -- essays research papers

     The defective Bang theory states that altogether the matter that is in the universe was once in a re all(prenominal)y small amount of dummy with infinite temperature, pressure, and density. This theory is puff up derriere up and there are m any reason for its support. One primary(prenominal) reason is that no one really has a clue and The free Bang Theory seems far fetched merely more reasonable than any new(prenominal) ideas that there are out there. Some of the authoritative intimacy to survive about the big bang to understand are the starting signal and the few seconds immediately after the actually bang. Also what generally has happened since the then. It is important to know theories of how it forget end as well, and to get a well rounded opinion, I feel it useful to be possessed of some of the other possibilities outlined. The best place to start is the beginning.     One of the things that cosmologists are non ti l now sure about is the heavy(a) Bang itself. It is not yet mathematical to give a definitive answer to the questions what was the Big Bang and why did it happen? How of all time, there has been a great deal of speculation late on this subject, and it may not be long before a definitive, or almost definitive, answer will be declared. For the moment we will simply take the Big Bang as it is given, a gigantic explosion in which time and space began expanding. It is important to realize that space itself originated in the Big Bang. IT is tempting to think of the universe before the Big Bang as being a vast, infinite, expanse of empty space, standardised the space between the galaxy clusters today. The Big Bang, then, would have flung matter into this nothingness, but this is not what happened. Space itself was created during the Big Bang. Einstein and all subsequent cosmologists have viewed space as being as real as matter. In fact, physicists now view empty space as a sea of vir tual particles. So space is now expanding along with the galaxies and stars that exist with it and has been expanding ever since the Big Bang.     Actually, cosmologists actually have a clearer picture of what the universe was comparable during the period right after the Big Bang than they are about the universe today.The reason for this is universe was very simple, in comparison, then. The universe was fill up with a hot soup of particles like a hot squander trapped in a box. The photons in the cosmic microwave bac... ...re is except so much energy available in the universe for the build of new stars. Just as the law of thermodynamics tell us that a closed universe cant go on forevermore, so they tell us that new stars cannot go on being created forever in an open universe. Eventually the last star will live out and will not be replace. The proton will eventually decay. by and by about a billion billion billion billion years, all atoms will fall apart, and matter as we know it will land up to exist. The universe will be a vast sea of leptons and courier particles.     One main, but unsupported, theory is that the universe was created by God. This theory is not excepted in the scientific community because in has no evidence to back it up. That doesnt mean it isnt a possibility. There are a few other theories of the creations of the universe, but no other theories are as excepted as the big bang theory. Some of the important stuff to know that I have covered is the eras right after the Big Bang, the Big Bang it self and a few of the possible endings to the universe. I rely with this information you can have a better understanding of the universe, its creation, and its endings.
