THE UNIVERSE IS UNCREATED, AS THE TIME ITSELF IS, WITHOUT BEGINNING AND END, BUT IT IS BASED ON THE PRINCIPLES…
Twenty billion years ago, something happened- the Big Bang, the event that began our Universe. Why it happened is a greatest mystery. As the big bang occurred, the universe had zero size perhaps a Mathematical Point with no dimensions at all and so must have been infinitely hot. But as the universe expanded, the temperature of the radiation would have been decreased. About a billion years after the big bang, the distribution of matter in the universe had become a little lumpy; as the big bang itself had not been perfectly uniform. Cluster of galaxies fill the universe today.
The suicide rate among galaxies is high. These galaxies are blowing themselves up displaying jets of radiations. Black holes and quasars ranging from millions to billions of times more massive than Sun are suspected in the universe. A quasar is the energy released when gas, dust and star fall into an immense black hole to reach other parts of the universe or even in other universes. In every quasar explosions, millions of worlds, some with life and intelligence may get utterly destroyed.
The discovery that the universe was expanding was one of the greatest intellectual revolutions of the twentieth century. The behavior of the universe could have been predicted from Newton’s Theory of gravity at any time in the nineteenth, the eighteenth or even the late seventeenth century. Will the universe eventually stop expanding and start contracting, or will it expand forever? To answer this question we need to know the present rate of expansion of the universe by measuring the velocities and its present average density.
The present evidence, therefore, suggests that the universe will probably expand forever but we are not really sure about it, it can collapse after at least ten thousand million years, since it has already been expanding for at least that long. This should not worry us since by that time; mankind will long since have died out, extinguished along with the death of our sun.
If the picture of an expanding universe and a Big-Bang is correct, then we must think over more questions. What were the conditions like at the time of Big-Bang? What happened before that? If God created the universe out of nothing, then of course ask next where God comes from. Thus origin of the Universe is an unanswerable question. If God has always existed, then of course universe has always existed. So long as the universe had a beginning, one could suppose that it was created by an outside agency. But if the universe is really completely self- contained, having no boundary or edge, it would be neither created nor destroyed. WHAT PLACE THEN FOR A CREATOR!
If there is insufficient matter to prevent the universe from expanding forever, it must have an open shape extending to infinity in three dimensional analogies. If there is enough matter, then it has a closed shape, curved like a sphere and light cannot escape from it then it is perfectly correct to describe the universe as a black hole. There may be infinite hierarchy of universes, universes within universes, endlessly. To enter these, perhaps a black hole would provide a way.
By mathematical calculation, it has been found that the black holes create and emit particles at a steady rate. The knowledge of Mathematics, Science, the use of all advanced mathematical theories, and an enormous amount of basic mathematics is required to know about the future of universe.
Einstein once asked a question: How much choice did God have in constructing the universe. At least He had the freedom to choose the laws and the principles that the universe obeyed. The usual approach of constructing a mathematical model for the existence of universe cannot answer about its Creator at present.
We have dreams; we have at present undisciplined but ever increasing power. Can we doubt that presently our race will realize our imaginations that it will achieve peace and life, in a universe made lovely than any place or garden we know, going on in widening circle of adventure and achievement?
The time will come when diligent research over long periods will bring to light things which now lie hidden. Many discoveries are reserved for ages still to come. Our universe is a sorry little affair unless it has in it something for every age to investigate. Nature does not reveal her mysteries once and for all.
