Black and white holes
Person discharging sleep less than 6 hours , significantly increases your chances to die prematurely. This conclusion Italian scientists investigated more than 1.3 million people in Europe , USA and Asia .
Employees of the University of Warwick and the University Federico II in Naples conducted 16 studies and calculated how much should last night’s rest. ” Stable mode , six to eight hours of sleep per night may be optimal for human health ” – emphasizes the lead researcher Francesco Cappuccio .
Experts estimate statistics and found that people who sleep less than six hours , the risk of premature death increases by 6-18 %. Do those who are in the realm of Morpheus spent more than nine hours per day, the likelihood of early withdrawal from life was increased by 22-38 %. However, the scientists explained that in this case too long dream probably is a symptom , not a cause of various diseases and the general deterioration of health , RIA Novosti reported .

The notion of a black hole is inextricably linked with the birth of stars . All particles newborn star ( protostar ), of which it is formed , are attracted to its center of gravity forces unopposed . Therefore, the star begins to shrink. As compression protostar its temperature rises , and at the core of thermonuclear reaction occurs . With increasing temperature in the inner layers of the star increases the internal pressure tending to unclench her . When there will be a balance of contraction (gravity ) and decompresses forces (centrifugal forces and internal pressure ) , the protostar turns into a star , and can exist in a stable state billions of earth years .
When all the hydrogen will burn and turn into helium, old age comes the star. And then – death. Large and small star die differently.
Small star , which include our sun die not so spectacularly as massive . When the gravitational forces of the Sun inward counterbalanced by repulsive forces existing between the individual particles , the compression process cease, and the sun gradually cools , becoming a white dwarf.
Otherwise, things with big stars . Here are two possibilities. Continue reading
Now … the very science that ” killed ” God restores faith in Him. Physicists have stumbled on signs that the cosmos is designed specifically for the existence of life and consciousness.
Steven Weinberg , a Nobel laureate in physics
Trying to explain the appearance of a universe without any of the Higher Forces , scientists in the mid-twentieth century created the theory that it was the result of the so-called Big Bang of the singular ( singular) point. The size of this point can be represented , acquainted with the statement of senior researcher State Astronomical Institute . V.Surdina Sternberg : ” The early universe was so small that even the atom proton compared to it might seem the Moon .” A point from which it appeared , was even less . Continue reading
Twenty years ago in our country, it was hard to find a man who would not in his time serving in the Armed Forces. For most of the stronger half of our society , military service is associated not only with the ” burdens and deprivations “, but with mysterious stories that happened to them as well as with their colleagues. On many occasions their mysterious witnesses have no right to tell , but some of them after so many years still becoming known wider audience.
In the late 60 – ies of XX century resident of Tomsk Stepan Nikolaevich Lezhnyov happened to serve as a sailor on the Kamchatka Peninsula , on the basis of the Pacific Fleet. One autumn day, one of the diesel submarine returned to base with damage caused by an unknown object. Among the command rose serious commotion. It turned out that two days on earlier this submarine ten miles south of the Commander Islands faced with a large underwater object . The collision on the hull formed several large dents, was severely damaged snorkel and lost contact with base and incapacitated electrical , which is only partially able to restore a few hours. Suggestion of a possible collision with a large marine mammals – whale , walrus or seal – was abandoned after an inspection of damage. On the ship’s shell plating could be seen clearly deep furrows , as if the boat collided with a solid , possibly a metal object. Another interesting fact was that neither before the collision or after the mysterious object was not seen nor radars nor acousticians diesel submarine . Continue reading
