The connotation and denotation of life is the core problem of the sustainable development of human kind. It is impossible for us to determine whether the value of humanity nowadays is right or wrong without figuring out this problem.
I am an ordinary man. Each time I got hit by life, I would ask myself this question: What's the reason for these? What should I live for? What is the meaning of my life? An obscure living all days is no better than to die.
However, the statement that there is heaven and hell makes one feel a little bit stupid to die like this. Maybe it is more appropriate to make the meaning of life clear before making decision for how to die.
But how can I figure out the nature of life? Where could I find out the meaning of life?
I started looking for the source of life and life's destination. I read several Buddhist scriptures first, then The Bible, The Qur'an, and Tao Te Ching, and skim through Seth's discussion about life. But the reading only makes me remain confused.
It seems that I had to look for scientific books. So I made some exploration on Newtonian mechanics, Einstein's special and general relativity theory, Quantum Mechanics, Superstring Theory, Cosmic Holygraphy, Unified Field Theory, and Stephen Hawking's A Brief History of Time. But I was still in a confusion state.
What left for me then was nothing but to make exploration lonely.
What occurred in my mind first were these questions: Why is the human body so symmetrical? What is the force creating this symmetry? The reason must lies in the original structure of life factors. Then what kind of structure is the life factor?
Matter is composed of molecules and molecules are composed of atoms. Atoms in turn, are composed of protons, neutrons and the extra nuclear electrons, and the next after which are the elementary particles and the space of sub- particles, and one of the later was named by Murray Gell-Mann of California Institute of Technology as quarks (also called straton by some Chinese physicist).
But what kind of structure is quark? According to professor Tsung-Dao Lee's saying, who won the Nobel Prize, even the existence of quarks was still a riddle to be solved.
However, although I'm not sure that if it is possible for the microscopic matter being infinitely divisible, I do believe the existence of quarks, since the structure of nuclei and extra nuclear electrons isn't that kind of symmetrical structure which will lead to the appearance of life.
Let's make an assumption that quarks do exist, is it the life factor? What are the elementary particles composing quarks again?
It is likely that it is impossible to make infinite division on particles, because neither a particle accelerator, synchrotron radiation appliance nor the neutron source can make it possible for us to "see" a very microscopic material world. So, we had to take elementary particles as the object for our study.
From the Wave-Particle Duality, we have known that each particle spins; quantum mechanics tells us that it seems that particles do not spin around the axis, because some of the particles are the same when observing from each direction, some are not the same until they turn a full circle, some are the same after half a circle, and sill some particles need two full circles before being obvious the same in our observation. Thus, the particles fall into two groups according to their spin: one is 1 / 2 and the other is 0, 1 and 2. According to Pauli Exclusion Principle and Uncertainty Principle, it is impossible for two similar particles to have the same position and velocity simultaneously. Dirac-Theory indicates that each electron must have its partner: antielectron, or positron, which means that each particle parallelizes with an antiparticle with which the particle annihilate itself quickly. On the bases of this, Stephen Hawking believed that it may also exist anti-world and anti-human consists of antiparticles. It seems that the particle annihilation theory comes close to the boundary of the symmetrical structure of life, but it is not the true sense of "real human".
The super-string theory is established for the purpose of combining quantum gravity field theory and general relativity together. Superstring theory suggests that elementary particles are not point particles, but a dimensional string; different particles in nature are different vibrational modes of one-dimensional strings. In this way, the micro structure of matter become a super-string, rather than in the form of particles, and it is just like the melody from a heptachlor.
But there is still a problem here: the M Theory which unify the five superstring theories and eleven-dimensional supergravity, as well as the Matrix theory, can not solve the problem of the unifications of the four interactions (gravitation, electromagnetism, weak nuclear force and strong )
Some people tried to explain this with the cosmic holography theory. The three holographic states are: physical state, motion state and thinking state. It means that in addition to mass and energy, there is a cosmic phenomenon- thinking, also known asenergy of thinking. In this way, the shackle of just concentrating on matter is broken because consciousness and thinking are also included. Hence, human knowledge made a big step in this aspect.
