If the Universe Is Teeming with Aliens ... WHERE IS EVERY...

Given that there are 400 billion stars in our galaxy and there may be 400 billion galaxies in the universe, we have found that at least once, once in this 14 billion years ago somewhere We are as advanced as ourselves. With a huge number of figures, it is almost necessary to accept the truth of this hypothesis. So then why are there no evidence from these aliens, no information or artifacts?

In the second part of his popular book, after major revision and expansion, Weber discussed in detail the most convincing and interesting solutions to Fermi's famous public opinion. I strongly pointed out the existence of extraterrestrial civilization, but why can not you find those evidence?

"Web books are amazing among the many books dealing with the possibilities of alien intelligence ... Each solution, along with layman's intelligence, is a very logical, interesting, and thorough way Description and commentary explanation: Webb digs solves the problem by considering a very comprehensive and detailed solution ... he will make this a fun and challenging presentation mode The book says, "Are we alone? (WE Howard III, Choice, March 2003)

"We propose 50 ideas ... to clarify clear and rational consideration about the so-called" Fermi paradox ". People who reduce imagination to the limit ... "Where is everyone?" This will be very informative and fun .... No matter what you think about living in other parts of the universe, Please read this book. Your evaluation of special life on your plan will be strengthened! This supplements every personal library. "(Philip Bridle, BBC Radio, March 2003)

Stephen Webb has a bachelor's degree in physics from Bristol University and has a doctorate in theoretical physics at the University of Manchester since working at universities in the UK. He is a regular contributor to the "Astronomical Yearbook" series and publishes undergraduate textbooks on distance measurement in astronomy and cosmology and several popular scientific books. His interest in Fermi's paradox combines the lifelong interests of science and science fiction.

He issued the "measurement of the universe - the ladder of the cosmological distance" and in 1999, if the universe is full of aliens, "First edition so ... ....: the most famous physicist Stephen Webb is the author of a popular science book In 2002, "Fermi's paradox and 50 solutions to extraterrestrial life problems", "get out of this world - 2004 physics and universe, Blanes, Strings, Other Wild Collisions "concept and" New perspective in the universe - 12 universe mysteries "and tools that need to be resolved in 2012

I want to know why we are still in the universe even if we return to the present. From the statistics, the universe should be full of alien species, but where is it? This is called Fermi's paradox. One version of this problem's "big filter" is that when reaching a certain level of technology, all intelligent living eventually self-destroys. If this is our fate, it also means the inverse relationship between technology and wisdom.

Please make another excuse under the category "Alien is dead". The universe may be filled with kind planets, but there is no guarantee that they will be long enough to evolve life. According to a survey of 2016 by the Australian National University, a damp rocky planet like the Earth was very unstable when I started my career. You can roll the ball in a very limited window (hundreds of millions of years). The authors of the research write as follows. "Life can be rare in the universe, it is not difficult to start, because it is difficult to maintain a living environment in the first 10 years."
