If you follow the calculations of Piran and Jimenez, the universe is so mild in old age. About five billion years gamma-ray bursts were so frequent that they had never allowed the emergence of complex life in the universe. But could that even now only one in ten galaxies life to develop undisturbed long enough to write the two researchers.
The calculations of Piran and Jimenez provide an elegant approach to resolve the Fermi paradox of our interstellar loneliness. Others see it as experts who were not involved in the study.
James Annis , a cosmologist at Fermilab, is one of the pioneers of the idea of the killer gamma-ray bursts. He published in 1999 a "astrophysical explanation for the great silence". "I read the article two weeks ago on the plane and find it great -. Even if I would have done a few things differently I think in recent years more frequently over the Fermi paradox after and am much more confident than they were in 1999 that the must be explanation in a time shorter for the development of intelligent life. And it seems to be the best mechanism gamma-ray bursts. " Finding life is always a way?
However, not all research colleagues follow. Seth Shostak is a senior astronomer at the SETI Institute in California. There, scientists are looking specifically for extraterrestrial intelligence. "If we have learned one thing over the last 20 years, it's that life is extremely resistant and adaptable. During the last four billion years of cosmic catastrophe could not stop the course of life on Earth." Even if the calculations were correct, remained at 10 percent habitable galaxies still about 100 billion planetary systems, the "good enough" are to develop life.
Tsvi Piran admits that he and Jimenez have focused on the development of complex and intelligent life. That is a plausible approach in the search for aliens. "It is almost certain that bacteria and other lower forms of life could survive such a gamma-ray burst and its consequences," he confirmed. "But for higher life it would be as if you press a reset button. It would have to start from scratch again. But you can easily imagine other forms of life, which can not be our arguments apply." Even if the elegant model of Piran and Jimenez so true - totally done away with the Fermi paradox is thus far.
