Humans can’t find aliens. They’ve destroyed themselves. Scientists have never suspected the existence of aliens, but whether they can be found is another matter.
Scientists say there is little hope that humans can find aliens. There are aliens in the universe, but they are likely to die out before humans find them.
There are about 200 to 400 billion stars and 100 billion planets in the universe, but there is no sign of extraterrestrial life, which has become one of the biggest mysteries in astronomy.
According to the daily mail of October 10, British physicist Brian? Cox said that human research on aliens will not produce results. Because, before evolution, extraterrestrial life had destroyed itself.
Professor Cox is known for hosting the “miracle of the universe” documentary series on BBC. In an interview with the times, he said that any form of alien civilization can lead to self destruction if its technology advances faster than the political system governing it.
Although science and technology have led to the development of energy, they have also brought greenhouse gases and nuclear weapons, which can destroy human civilization for thousands of years and threaten human beings themselves.
Recently, Professor Cox and physicist Geoff J. Manchester university? Fu Xiu cooperatively published a book, a guide to the universe.
They believe that the Big Bang is only one of the major events in space, there must be other space, and the physical operation rules of each space are different. These ideas may seem odd, but the evidence is strong and consistent with reasoning, according to Prof. Fukuo.
We’ve been looking for aliens, and we’ve searched all the areas we can see. Where are the aliens? Are they really out of order? Scientists say that only a planet with a stable circular orbit like the earth can have life.
If extraterrestrial life does exist, they are likely to exist in stellar systems with many planets. A recent study shows that the more planets around a star, the closer the planet’s orbit is to a circle.
Planets in circular orbits should not be too close or too far away from the stars, and their climate should be mild enough to breed intelligent life.
Our own solar system fits this pattern. The sun has eight or nine planets (depending on whether you think of Pluto as a planet or not), most of them in nearly circular orbits.
For example, the eccentricity of the earth’s orbit is only 1.7% (the eccentricity ranges from 0% to 100%, representing a circle to an extremely slender ellipse).
Mercury and Pluto have elliptical orbits with eccentricities of 21% and 25% respectively. However, even Pluto (whether it is a planet or not remains controversial), its orbit is relatively round compared with other planets around some stars, whose eccentricities may exceed 60%, 70% or even 80%.
“As far as we know, this kind of ‘barbaric world’ exists only in stellar systems with only one or two planets,” said Mary Anne limbach and Edwin L. Turner, astronomers at Princeton University, who initiated the study.
In contrast, if a star system has four or more planets, the orbits of these planets will be closer to a circle.
This conclusion is based on their analysis of 403 planets in hundreds of stellar systems, published in the January issue of the proceedings of the National Academy of Sciences (PNAs).
Jack Lissauer, a planetary scientist at NASA Ames Research Center, points out that planets in circular orbits are more likely to give birth to life because they don’t interfere with each other.
Lindbach also said that if a planet’s orbit is a long oval, it may “cross the orbits of other planets, thus knocking other planets out of the original system.”.
Planets with narrow orbits will not only bump into other planets like reckless drivers, but they will not be suitable places for life themselves – they will be roasted too hot when they are close to the sun, and they will freeze into ice balls when they are far away from the sun.
Therefore, intelligent life is more likely to exist on planets with circular orbits, and there will be a variety of other planets in their planetary system, and they will even quarrel over whether a planet is a real planet – just like us.
