7 difficult Question Answered by Scientists

According to the report <<Daily News>> English, along with the development of technology and social progress of society, people have a deeper knowledge of the nature of a large number of happenings. But against a number of other problems until now, scientists still have not been able to provide answers and explanations. such as:

1. Do dogs have a sense of humor? 
Scientists researching animal intelligence, they increasingly recognize such a view: the behavior of animals rather than just react instinctively, but an unconscious reaction, a substance thought they made him have the ability to feel love, anger, sadness and joy and even a sense of humor through sensory organs.
For example researchers have found that elephants can recognize themselves in mirrors (lots of kids who may not be able to act as such) an orangutan (or perhaps some birds) can learn a number of beginning-level language and create a complicated equipment. It is conceivable, if the bird can make a hook (hooks) with electrical wire, hook to use food from cans, then is not so cruel when using them as an experiment that torture?

2. How is the origin of life?
 If you want to make a biologist, you simply ask how the origin of life. Since 150 years ago, Darwin continued to think and he thinks that all life on earth comes from the "prebiotic soup". But until now, we are still thinking about the origin of life.We do not know the range of knowledge related to the origin of life, such as how the first, where and when life begins, and whether life begins from life to death took place only once or repeatedly, and so on.Some scientists suspect, lhfe came from underground, or around the lip of the volcano bursts. Other scientists currently suspect, that a single microbe was the ancestor of all living things on earth. At about 3 billion years ago, the planet Mars when it's warm and humid, while the earth is only a cold desert, this single microbes fly to earth along with the destruction explosion rocks on Mars. According to this view, means that we are all human beings from the planet Mars. But until now, all of these allegations has never been proven. So it can not convince anyone. The origin of life, it is likely the most mysterious is the mystery in the universe.

3. Is the inner reaction is just nonsense?
 Most scientists say do not believe in an abnormal phenomenon, because these phenomena violate the principle of normal and can not be explained by the experiment. But if we can say that crystal therapy (using the crystal energy in order to "magnetic field organisms' body back in a state of" balanced "and the inner reaction that is crap?)"Abnormal phenomena" includes the power of Gamma (d), "spiritual", the chatter of a new era (new century), astrology, divination cards / tarot, scientists have reason assume that the abnormal phenomenon is a pseudo science. But scientists on the contrary, they are careful and rational in scholarship, often publish their latest research findings in Science magazine of leading. "But when the crystal therapy techniques horoscopes and believed to be only as an entertainment and not a science, then what about the inner reaction, acupuncture therapy and hypnosis techniques? It remains to be investigated scientifically. And of course, the inner reaction may also be evidenced as a bird news, who knows? no matter what the outcome, must try to find the real facts.

4. What is time? 
If you want to make a physicist, ask him: "What is time?" Because, we will not know the answer.There is a rumor that said, time is a magical weapon that block the natural activity of all objects simultaneously. Time can define our lives, because we rely on to measure the life time. But in terms of what it is time, we just like the ancients, also did not know anything. And of course, this does not mean we do not know what he had done time. Physicists like Einstain, in which case the characteristics of the time had a view of the inside. So we can give a sign at the time, then enter the time into the equation are not equal, and thus we can examine a large number of phenomena and draw conclusions.However, this can not yet tell us exactly what time. Is it a "river" that flows from the past into the future? if yes, then the river is it? What drove her to move and flow velocity based on what the river flow? if time is a river, whether it can flow upward through this river? and whether we can completely stop the flow of this river flowing?This allows the fiction novelist said. What amazes us is, physicists also think like this. But before we create a time machine, we must know very well against a difficult time at the touch and easy to disappear in this glance. Until the last day, we will uncover the mysteries of this mysterious. But if so, then it certainly would appear even more mystery. Perhaps the only consolation is decent, if someday we can reveal all mysteries, and if it is really solved, then everything will be bland.


5. Why is obesity from day to day increasing? 
At 100 years ago, the world's hardly a single case of obesity, for 100 years, obesity has become an unparalleled crisis unmatched in the history of human disease. If calculated according to the current situation, we will increasingly overweight.Because obesity is very clear: eating too much, lack of exercise. But the condition is not as simple as this. Rarely the first to know, in a large number of nations "obesity" in the west, such as the United States, the heat dissipated people far less than the heat is spent on people 50 years ago. Compared with those in 1950 ago, we rarely walk, the place is the large number of motor vehicles. Obesity began to flourish since 1980, compared to when it is, sports are much less done.A large number of scientists believe that the proliferation of obesity must be hidden behind a deep mystery. Some scientists have said that obesity may be caused by a virus, or can be explained by genetics.

6. Whether humans can stay young?
 What can we stay young? might be, maybe not. Preventing aging is one thing that most do not like to talk to scientists, because this can cause a series of issues such as morality and logic, or the things that real headache.First, in reality we do not know what exactly it is aging. In our view, when we are old, or the physical body itself will also join the old. But in reality it is not. First 20 years of age of our lives, our physical from day to day and contains the powerful, the function of our bodies we are more and more effective, more powerful disease-fighting capabilities. However, why in the following days (get older), it becomes very opposite?
According to evolutionary theory of aging, why does our body functions begin to experience aging is estimated at 30-50 years of age men will die from cold, hunger and death in the wild tiger's mouth and so on. But if we can not live so long, we really do not need evolution, to face the pain of old age. But this can not explain, where when we get old, what changes have changed the "bell" gene, so that makes our skin becomes dry, the hair becomes white, bones become brittle. Only after we know exactly what causes this change allows new take steps against aging.But we will face a moral issue: are we willing to live in a world in which human beings will not be old forever? or in other words, are we really willing to live in a world like that if only a small number of elite society that just lucky to be able to enjoy this ageless treatment?

7. A minute ago I do the same with me now?
 "Do I still like a minute ago?" This sounds like a very strange question! But this is one of the most frustrating problem in the whole world of science and philosophy. That is a matter of identity recognition. On the surface, the answer clearly is: "certainly, I am the same person at the last minute. But try to think about again for a moment. "10 minutes ago, all the things that every cell in your brain is totally different from the things that your brain cells right now. Every few years later, your body is almost completely changed once. Whether Cutty Sark can be re-created with new wood and a variety of new components, if would be exactly the same as Cutty Sark sailing over the sea in 150 years ago it was? To this, refining the theory answers is: "No". That way, you are no longer your child's future. This question suggests, that our consideration of the individual is always in contradiction with the real atmosphere is going on. And how do we recognize the identity of the same person, whether based on DNA or something else that is more vague again? (Source Tom.com)
