พอดีผ่านไปเจอกระทู้ของคุณ Chatz ที่ชื่อคล้ายๆผม เลยลองเข้าไปอ่าน Lecture ของ Professor Stephen William Hawking ที่เค้าบอกว่าเป็นหนึ่งในสามนักฟิสิกส์อัจริยะก็เลยเกิดคำถามขึ้นว่าจากบทความนี้
The time scale of the universe is very long compared to that for human life. It was therefore not surprising that until recently, the universe was thought to be essentially static, and unchanging in time. On the other hand, it must have been obvious, that society is evolving in culture and technology. This indicates that the present phase of human history can not have been going for more than a few thousand years. Otherwise, we would be more advanced than we are. It was therefore natural to believe that the human race, and maybe the whole universe, had a beginning in the fairly recent past. However, many people were unhappy with the idea that the universe had a beginning, because it seemed to imply the existence of a supernatural being who created the universe. They preferred to believe that the universe, and the human race, had existed forever. Their explanation for human progress was that there had been periodic floods, or other natural disasters, which repeatedly set back the human race to a primitive state.

If one can determine that there is enough matter in the universe, to focus our past light cone, one can then apply the singularity theorems, to show that time must have a beginning.
แล้วก็บทสรุป
The conclusion of this lecture is that the universe has not existed forever. Rather, the universe, and time itself, had a beginning in the Big Bang, about 15 billion years ago. The beginning of real time, would have been a singularity, at which the laws of physics would have broken down. Nevertheless, the way the universe began would have been determined by the laws of physics, if the universe satisfied the no boundary condition. This says that in the imaginary time direction, space-time is finite in extent, but doesn't have any boundary or edge. The predictions of the no boundary proposal seem to agree with observation. The no boundary hypothesis also predicts that the universe will eventually collapse again. However, the contracting phase, will not have the opposite arrow of time, to the expanding phase. So we will keep on getting older, and we won't return to our youth. Because time is not going to go backwards, I think I better stop now.

แล้วทำไมบางคนไม่เชื่อใน God ครับ

ในทางกลับกันจากหนังสือ Big Quesions in science, Edited by Harriet Swain, Introduction by John Maddox หน้าที่ 5
Nobel Prize-winning physicist Steven Weinberg agree that 'the more the universe seems comprehensible, the more it seems pointless'. He argues that the prevalence of evil and misery proves that there is no benevolent designer.
ทำไมเค้าถึงคิดว่า 'the more the universe seems comprehensible, the more it seems pointless' ครับทังๆที่ดูจากหลายๆทฤษฎีตามที่ Professor Stephen Hawking กล่าวมามันควรจะมี God นิครับ
