From the alien has not found reason to talk about how humans will probably ruin their own hands
In the human birth of several hundred million years of human civilization gained rapid development, only the last 100 years, humans have created a lot of amazing technology.
human exploration of the universe to be bold than ever, 50 years ago, we will be men on the moon, and the construction of the huge orbiting space station; 30 years ago, the human spacecraft reached the solar system distant planets; 15 years ago, human Mars probe login, login and send humans to Mars in 20 years ......
human exploration of the universe faster and faster, as if found outside Star who just a matter of time. If the existence of extraterrestrial civilizations, when they tell us to develop a similar stage, will be to explore an alien in their eyes.
So why up to now we did not find conclusive evidence of the existence of aliens it?
want to solve this problem, which had to mention a terrible mechanism that exist in the universe - civilization filter .
civilization filter means exists in the universe there is no objective mechanism for the evolution of life in the barren land to interstellar civilization.
civilization filter on a good explanation of why Earth is so "lonely" mentioned earlier. Specifically how to explain it? Listen to my analysis!
that is in the process of evolution of life to a higher civilization, there is one threshold, each threshold will perish part of life, to reach the final of the interstellar civilization of life are few.
This filter contains a total culture nine threshold (a threshold for each relationship is progressive, from low to high):
1 star systems →. 2. a self-replicating molecule → 3. unicellular prokaryotic → 4. multinuclear single cell → 5. sexual reproduction → 6. multicellular organisms → 7. tool biological → 8. primary culture space → 9. interstellar civilization.
So, the current stage of human civilization in which it?
currently, in the eighth stage of primary human space civilization, a civilization that is preliminary master space technology. To also move towards a higher level of interstellar civilization, in the middle there is at least a threshold to cross, to reach the ninth grade of civilization. If you reach the last civilization, civilization can reach the level of God almighty. And most of life in the universe, may all be within the threshold of 1-8.
So this explains why the Milky Way has stars in it 2000-4000, 1000-2000 observable universe has one hundred million galaxies, mankind's most powerful telescopes can observe up to 180 million light-years far away, but we did not find any signs of interstellar civilization.
filter according to civilizations theory, if humans will eventually perish, probably because there is encountered insurmountable threshold. So if we can not cross this threshold, what is the biggest of several possible is it?
artificial intelligence - first, "chicken" or to have "egg"?
Artificial intelligence is the science and technology branch is currently focusing on the development of human, artificial intelligence expert Kurzweil believes that by 2045, artificial intelligence will reach the pinnacle of creativity, today more than 1 billion times the sum of all human intelligence that time artificial intelligence will surpass human beings in terms of computing power, but with a sense of fair distance away from the real, but only with the development of technology, artificial intelligence development from my consciousness is only a matter of time.
when to start thinking about artificial intelligence, and tried to control mankind is not the time, the reality version of "the Matrix", or will occur! To the time, there is no way these humans may be self-aware artificial intelligence body counter, it is likely that the demise of mankind to the moment.
new brain hole again, if artificial intelligence can really destroy the human race, then the universe must have a similar species able to produce artificial intelligence wiped out native species, with their superior thinking ability to continue to replicate and development, eventually colonized the galaxy, right?
If so, should the whole universe filled with a bio-artificial intelligence, but the reality seems not. There are two possibilities:
- civilization they created a lot of artificial intelligence has not produced to the point where they can threaten perished.
- If similar human civilization really been replaced by their manufactured artificial intelligence, while we could not find a trace of the artificial intelligence body, they are likely to have evolved from physical form to the carrier, perhaps become a pure energy of body awareness, even those of us who are of the universe, these are likely to be created by artificial intelligence.
cobalt bomb - over the ultimate" Shazhao "Nuclear weapons may no longer be ideal?
since man invented the first atomic bomb, nuclear weapons became the most deadly human weapons, and is constantly upgraded.
1945 in August in the United States dropped two atomic bombs on Hiroshima and Nagasaki, TNT equivalent of 20,000 tons and 22,000 tons, more than 200,000 casualties. Then the Soviet Union joined the ranks of nuclear weapons competition, the US and the USSR to spare no effort to develop nuclear weapons.
1960, the US thermonuclear weapons manufacturing MK-41, TNT equivalent of 25 million tons, equivalent to 1000 Hiroshima. This simple model of the US nuclear weapons, there are 500.
Soviet Union, not to be outdone, then produced the two the world's strongest in the history of nuclear weapons - Tsar Bomba . It's TNT equivalent of 60 million tons, equivalent to 3000 Hiroshima atomic bomb. The last test explosion mushroom cloud height reached an altitude of 60,000 meters, equivalent to the height of the beads Mulang Mu peak of seven. This time the explosions, let the Eurasian continent to the south moved 7 mm!
these strong return strong nuclear weapons, but want human extinction is not enough, scientists have calculated that, in accordance with the effects of the explosion Tsar Bomba, in order to destroy the entire planet is far far enough, at least 1.5 billion tsar bombs explode. Humans apparently unable to extract the uranium needed for nuclear weapons so much.
so, the future of mankind because if nuclear weapons are destroyed, must have invented a more advanced nuclear weapons. Is there a nuclear weapon much more powerful than the nuclear weapons it?
There! But it is a vision of ultimate nuclear weapons - cobalt bomb .
wrapped in a layer of cobalt is assumed that 59 out of the neutron bomb detonated in the stratosphere, neutron emitted from the neutron bomb blast hit the cobalt becomes 59 cobalt 60, cobalt 60 run all over the Earth's atmosphere in the stratosphere. Cobalt-60 radiation decay will destroy biological DNA, destruction of all life on earth will in a short time. This level of destruction is the nuclear bomb, but also produce more intense gamma rays.
As long as a small number of cobalt bomb, you can destroy all humanity and all life on Earth. If the cobalt bomb is manufactured, humans may end below the cobalt bomb. cobalt bomb is perhaps the real-life version of Thanos snapping his fingers! An idea, barren.
I can only talk about the current article from two perspectives on how humans might" seek death "of their own, if you have any other ideas, please share with me!
can point you feel good praise, concern me, more science sharp dry all in @ Casa science . If you have any ideas and opinions are welcome discussion in the comments section!
