1.      What is the heavenly interpretation of emotion?

Since the beginning of human history, human beings have been
continuously exploring the nature, and extending the boundaries of
understanding of the nature. Columbus’s discovery of the New World is
a good example. Where is the human courage to explore the nature from?
It is from the power of human emotions. Then, what are emotions? This
question is actually the literary theme that has been explored for
thousands of years.  In the eyes of some literature writers,
physicists are cold-blooded and without emotion. I'm a physicist, but
I do not blame writers for this. Although physicists have made a great
contribution in the exploration of nature, they have never given the
physical definition of emotions, or found a shred of evidence of
emotions the nature contains. Although aware of the existence and
development of the humans are inextricably linked with the natural
environment, very few humans appreciate the natural environment for
emotions. In many people's eyes, nature is a dead and an unforgiving
material world. As a Chinese proverb goes, "the heaven would grow old
if it had emotions". It is not surprising that, because almost all
human beings believe that the heaven is not old, so it has no
emotions. In this paper, a model of birth and aging of the universe is
proposed.  Although simple, this model can explain most of important
observations.  However, facing rejection at beginning might be its
inevitable fate.
