Using the value of H, T works out to be 15*109years, or 15 billion years. 0000001032 00000 n x�b```f``�������� € "�@�����p@A������A���Iu���g�gT �ͽ�^��f��/F� L��Q�� St.Augustines thesis and antithesis (Quoted from Stephen Hawking’s “A brief History of time”), “The questions of whether the universe had a beginning in time and whether it is limited in space were later extensively examined by the philosopher Immanuel Kant in his monumental (and very obscure) work Critique of pure Reason,published in 1781. It is at this moment that the concepts of space and time came to have their present meanings and the laws of physics as we know them became applicable. Modifica ), Stai commentando usando il tuo account Google. Thus time was completely separate and independent from space. The time was unique to everyone. His argument for the thesis was that if the universe did not have a beginning, there would be an infinite period of time before any event, which he considered absurd. Newton (father of classical physics) himself believed in absolute time. Umm …. At that point of time all our laws of science to predict future or past would breakdown .Thus before this point we cannot imagine nether space and time. GIOVANNI da Ripatransone (Ripa; Giovanni della Marca).

Thus you use your energy to achieve the previous state. Since the speed of the light is just the distance it has traveled divided by the time it has taken, different observers would measure different speeds for the light. The Congregation for the Doctrine of the Faith, after careful study, has judged that the book Jesus Symbol of God (Maryknoll: Orbis Books, 1999), by Father Roger Haight S.J., contains serious doctrinal errors regarding certain fundamental truths of faith. First we have to understand —-why time always moves forward? As water can be formed again by melting ice, balloon be deflated when air is released from it. It states—“If a process in an isolated system occurs the entropy of the system always increases (Or remains constant for some cases)but never decreases.“. Say a child blows it again. 0000067175 00000 n 7–10, Pages: Biblioteca personale Introduction. 85–90, Pages: But if I say that when we consider an isolated system changes which occur are always irreversible.Let us consider the example of inflation of balloon.

He called these questions antinomies (that is, contradictions) of pure reason because he felt that there were equally compelling arguments for believing the thesis, that the universe had a beginning, and the antithesis, that it had existed forever. They are both based on his unspoken assumption that time continues back forever, whether or not the universe had existed forever. 0000001615 00000 n Cerca nel più grande indice di testi integrali mai esistito. According to relativity the flow of time for the second observer would slow down, by the relation. 35–44, Pages: Email This BlogThis! 133–156, Pages: Well the most ironic answer I came across was from an anonymous graffito on a wall of a street cafe in Austin, Texas which read “Time is a God’s way of keeping things from happening all at once!!”. In his detailed and careful analysis Ruokanen demonstrates that Vaticanum Secundum understood non-Christian religions as naturally good entities, part of human culture. In classical physics space and time was considered independent or time could be considered an absolute quantity. To understand this we have to first understand changers. In which H is the proportionality constant called the Hubble’s constant. 105–113, Pages: Alessandro Torlonia: The Pope’s Banker: Amazon.it: Felisini, Daniela: Libri in altre lingue Now allow me to introduce one of my favorite laws of physics. Posted by Mr.Singularity at 23:46 No comments: . Here the word “before” loses its meaning.T=10-43seconds.This is the earliest time known as the “Plank’s time “at which we can say anything meaningful about the development of the universe. Pages: Also there was no “before” the big bang because time began with that creation event. 91–103, Pages: The radiations originated after 300,00years after the big bang .As universe expanded the temperature dropped to its present value of 2.7K which shows that the universe has reached the final stages of its expansion the temperature is close to 0K, The Big Bang (Derived from Fundamentals of Physics by Halliday, Resnick , Walker). �?���Q�XX{�����Q����!�����;�D����`jh��7.�lhma,hkf 0�R�5:Z[��,�圎��r*��V�@''��S@[�����q��3������������R��3/[3������������V0��uV��V2�w��L��:;Z������� �?$#3����������h���������M-���4�]_�3��L��p������3�v�����v�Qꯒӝ���N �ͮ��>ԟsF�S���ޢ�{ UO��VY|���lݹx�d��~i��J֥��s�g&��,C��I�y��c:dL�˼{��Je�H$� �p7�P��^V�%9r�v��q�� *:K�ʹ��m@?V>Ɉ�:"R7B��Jv Z] �mNޫjL[�V�����?�?-|�w�h�b����� r9�E��l�.������C�.

Now you may tell me that if I assembled all the balls in the bucket just like the before then ? ( Chiudi sessione /  1–6, Pages: ( Chiudi sessione /  This was first pointed out by St. Augustine. theological faculties and seminaries, special institutes or schools involved in missiology or ecumenics, specialists and students of missiology and ecumenics. How we came to know that there was a beginning of time? 157–158, Pages: Dedicated to Stephen Hawking 0000039313 00000 n Example when you throw a glass dish on a solid concrete wall it breaks into pieces. Please forgive me if I have hurt someone’s sentiment. Thus the entropy gives the time its arrow that’s why things never happen backwards. It appeared that each observer must have his own measure of time, as recorded by a clock carried with him, and that identical clocks carried by different observers would not necessarily agree.”. If we look beyond our immediate galactic neighbors we find an astonishing fact. Therefore you cannot beat this law. 0000001689 00000 n But the law of physics prevents such mishaps, Einstein’s theory of relativity states that they both will see same speed of light. 0000066428 00000 n But things might become more twisted if I ask —-Where does this difference between past and future came from? That all the broken pieces all by itself starts to join together to form the unbroken piece you had before breaking it ! 55–61, Pages: In the previous paragraphs we have see how our concept of absolute time has changed over the years.

Thus the entropy of the system has increased. that is one could unambiguously measure the interval between two events and it would be same for whoever measured ,wherever measured it or whatever speed he was in while measuring. Although our position in the universe is insignificant, the laws of physics that we have discovered (Philosophically “Uncovered”) seem to hold throughout the universe and so far as we know that the universe also had a beginning .Thus until someone complains, we are entitled to stamp the laws of physics “Discovered on Earth.” Many remains to be discovered .As the above authors says that “The Universe is full of magical things, patiently waiting for our wits to grow sharper”. In 1965 Arno Penzias and Robert Wilson, what was known then the Bell telephone laboratories were testing a sensitive microwave receiver which was used for communication research. In other words, the theory of relativity put an end to the idea of absolute time! While there were many controversial values for H considering H=63.0Km/sec Mpc Where Mpc (Megapersec) is a length unit used in astrophysics and astronomy.We interpret the recession of the galaxies to mean that the universe is expanding, as like a balloon being inflated. Religions express in many ways and to varying degrees the natural cognition of God and of natural moral law. A brief History of time by Stephen Hawking 121–131, Pages: Now each observer would have his own measure of time as recorded by his clock he carried which might not agree with others. xڔ�ctf]�-�Tl[O����m��۶m�b۶m�b;��������}��q���F�}��fk��XA�N���(fg�L�D��1�uʪ�)�\� ���������Ž@Cg;[Cg @�� eh`b0�s1�s���899��ɺ8���aeae��beaa���{8Z��;����%���#����=������_����� ,� � gGC��������x��� `ba�0�Y��2�GQ���v &��&.��Ź��9������Tgbgk�0��2��9[T�?���0����3�� ik���&� Akk��ȝ J@'���?��u�������E�3��������?E�ۑ� Let me put another logic (Quoted from Stephen Hawking’s A brief history of time), “In Newton’s theory, if a pulse of light is sent from one place to another, different observers would agree on the time that the journey took (since time is absolute), but will not always agree on how far the light traveled (since space is not absolute). However with the advancement in Einstein’s theory of relativity we saw that speed of light appeared same to every observer no matter how he was moving. the discovered a faint background “Hiss” that remained unchanged in intensity no matter where their antenna was pointed. In relativity, on the other hand, all observers must agree on how fast light travels. Thus absolute time was considered one of the fundamental postulates of physics ,until1905 in famous paper a hitherto unknown clerk in Swiss patient office, Albert Einstein pointed out that the laws of science must be same for all freely moving observers no matter what their speed might be. 965-973. ll passo della Congregazione per l'Educazione Cattolica è citato da Spiritual formation in Seminaries (1980), in Enchiridion Vaticanum 7, Bologna, Edizioni Dehoniane 1982, alle pp. 71–83, Pages: Speed of light is constant (A fundamental law of nature).
