It is not only the first interstellar object ever observed, but also the limited data astronomers obtained when it rushed out of the solar system puzzled them.

Even today, five years after the interstellar visitor flew over the earth, scientists are still uncertain about its truth and origin.

Finally, the only way to get some real answers from it is to catch up with it.

In a paper recently published on the preprint website, scientists from Britain and the United States put forward a specific plan to catch up with Olmo. If this plan is implemented, the spacecraft launched from the earth in 2028 will catch up with aomomo in 26 years and take pictures of it for astronomers to study. After that, the probe will sail for nearly 18 years, and finally approach omao around 2050.

Does alien civilization exist? It brings inspiration. Human exploration never stops.

Excluding comets and asteroids, Harvard professor believes that aomo must be the product of alien technology.

The search for extraterrestrial intelligent life is endless - as evidenced by countless books and movies. Most fictional descriptions of close contact involve a noble connection, which is the collision and blending of enlightened ideas and cultures under the peaceful exchange of smart technology.

Scientific ideas like Drake’s equation, which attempts to formalize the broader theoretical parameters of intelligent life outside the earth, have not given a clear result to the possibility of other life in the Milky way. If intelligent aliens really exist, they have not left any footprints.

However, a famous scientist said that someone had found signs of them.

In 2017, no matter what happens tomorrow, it may be our first formal meeting with alien technology - astrophysicist Harvard professor avi Loeb wrote in his book “extraterrestrial visitors: the first sign of extraterrestrial intelligent life” published on January 26.

Alien technology may have entered the solar system

Professor Loeb has put forward a convincing explanation in his forthcoming book on why the slender axial object such as “Olmo”, which swept the solar system in 2017, is not just a space rock.

He believes that aomo may be one of the products of alien technology that no longer exists. The object came from Vega’s direction (25 light-years away) and entered the plane of the solar system on September 6, 2017.

“It broke into the plane of the planetary rotation orbit in the solar system on September 6, 2017,” Loeb wrote. “But the extreme hyperbolic trajectory of this object ensures that it will only visit the solar system, not stay.”

Aomomo has a small and constant acceleration

After passing the perihelion of its orbit, “it began to leave the solar system: it was fast, moving at a speed of about 94800 kilometers (58900 miles) per hour relative to the sun, so as to ensure that it was free from the gravitational pull of the sun.” Loeb wrote in his book.

“It passed through the orbit of Venus and the sun on September 29, for example, and passed the earth on October 7, rapidly moving towards the interstellar space in the direction of Pegasus.”

The acceleration of aomomo is small and constant, which cannot be explained by solar gravity.

The acceleration of strange objects puzzled the scientific community

Comets also gain acceleration when they release gas, which condenses into their iconic tail. But aomomo didn’t have that tail, and the telescope didn’t find any signs of by-products related to gas emission, such as dust or water vapor. Astronomers try to rule out one theory after another and try to find out the cause of aomo’s strange behavior. It did not collide with other celestial bodies, nor did it gain speed from the solar wind.

A research team believes that the best explanation is that due to the unusual element composition of the “miniature comet” aomomo, its tail has not been found. Another group believes that the o’momo is composed of frozen hydrogen, which is a modified small comet theory.

Harvard professor claimed that the brightness of aomo is the key to its origin

However, the most interesting narrative comes from Professor Loeb, who believes that Olmo is not what we think of as an interstellar celestial body, but a product of an alien civilization.

“Long before we knew the existence of Olmo, it had moved towards us from Vega, and it was only 25 light-years away from Vega.” Loeb wrote in his book. However, ground-based and space-based observations following the outward trajectory of celestial bodies confirm that sunlight is reflected on the surface of omamo.

“The changing brightness of a celestial body provides valuable clues for astronomers to study its shape.” Loeb wrote, “the brightness of aomo changes ten times every eight hours, from which we infer that this is the time it takes to complete one rotation.

Harvard professor claimed that aomo was the product of alien civilization

“The magic brightness change of aomo tells us that the shape of aomo is extreme, or its length is at least five to ten times longer than its width.” Loeb wrote. The evidence seems to point to a relatively small cigar shaped object.

“This must be an unusual celestial body.” After reading the narrator of NASA’s video, the new Yorker reported, “and unfortunately, we can’t get more observations of Olmo anymore. It’s too dark and too far away from us.

Excluding the possibility that Omar is a comet or other asteroid, Professor Loeb believes that there is only one explanation left: this puzzling object is the product of advanced alien technology.

Unusual claims require extraordinary evidence

“Our civilization has sent five man-made objects into interstellar space: Voyager 1 and Voyager 2, Pioneer 10 and Pioneer 11, and new horizons.” Le

Chen Li believes that in the process of continuously deepening the mining of data elements, we should resolutely correct and solve some unhealthy and non-standard signs of platform monopoly, information security and user rights and interests, so as to give full play to the role of data as a factor of production and ensure the healthy and orderly development of the data element market. Therefore, it is suggested to speed up the cultivation of data factor market from the following six aspects:

First, to promote the overall planning of the data factor market, we need to coordinate the forces of enterprises and society under the regulation and supervision of the government, and promote the market-oriented allocation of data in a multi pronged manner.

Second, improve the basis for the development and transaction of data production factors, form the basic framework for the initial distribution of data factors according to the market evaluation contribution and the determination of remuneration according to the contribution on the basis of clarifying the property rights, and formulate a policy system to improve the redistribution through fiscal and tax tools.

Third, establish a data classification and hierarchical management system, sort out different types of data in various industries, screen out non sensitive, low-risk and relatively clear data resources, give priority to entering the data trading market in the form of elements, and allocate data resources efficiently.

Fourth, improve the data quality, fully develop the application scenarios of data production factors, stimulate the motivation of service subjects through market demand, lay a good foundation for data quality evaluation and application, establish a data quality management system, and achieve the quality goal of big data.

Fifth, build an open sharing pattern of data elements, including promoting the open sharing of government public data to form a demonstration effect, integrating all kinds of data and giving play to the synergy of data elements.

Sixth, improve the security mechanism of data elements, forcibly encrypt data according to data classification, establish data access management rules, and set control authority to prevent internal data leakage.

The doctor preliminarily judged that the airway mucosa was damaged and the sense of foreign body was caused by esophageal injury.

Mr. Zeng tried to induce vomiting by himself and remove the foreign body, but many attempts failed.

On the way to the hospital, the emergency doctor continued to monitor Mr. Zeng’s condition. After arriving at the hospital, the doctor found through perfect examination that the foreign body sensation in Mr. Zeng’s throat was mainly caused by esophageal injury, which can usually heal itself.

The doctor suggested gastroscopy to determine the location of the foreign body, chew carefully and swallow slowly without talking or laughing.

Dr. Xiong said that if a foreign body gets stuck in the throat, it can be nipped out with tweezers, Heimlich first aid, timely medical treatment and other treatment methods according to the size and depth of the foreign body. When eating, don’t talk, laugh or joke. When eating, you must chew carefully and swallow slowly. You must chew it carefully before swallowing it.
