Mysterious aliens: Exist or not exist? (Part 3)

In recent years, scientists have discovered that many planets may be eligible for life to grow, the problem is that at the current level, humans have not been able to go there to verify. But with logical thinking plus what was discovered, was it enough to declare aliens real?

From religious theory and science

Most religions believe that in addition to humans there exist other intelligent life forms, such as gods, angels or even demons . Gods, angels and demons are all life forms intelligent and obviously not our world. Is it reasonable to see them as aliens? If this treatise seems generic, then among the two major religions of mankind today is Christianity and Buddhism, there are still specific theories about "another world" , ie extraterrestrial life.

In Christianity, since 1277, the Paris bishop, Etienne Tempier, declared that God may have created "more than one world" . In Buddhism, the scriptures have long been referring to the theory of "the three great natural worlds" (3,000 great worlds) of Shakyamuni Buddha. According to the calculation of Buddhism, a small world of the world = 1,000 worlds, 1,000 miniatures of the world = 1 center of the world, 1,000 center of the world = 1 heavenly world So the world's 3,000 great heaven will be equal to 3,000 billion world. In other words, Buddhism believes that as many as 3,000 billion worlds are like the world we live in.

In the 16th century, Giordano Bruno thought that the universe was endless and all stars were surrounded by its planets. And by the time the invention of the telescope (17th century), people really believed what Bruno said when he saw that the Earth was just a very small planet in the countless celestial bodies.

So famous scientists like Carl Sagan and Stephen Hawking argue that "there is no reason that resurrection cannot exist anywhere other than Earth." This argument is based on Copernicus's view that the Earth does not occupy a particular position in the universe. Therefore, life may have developed in many places in the universe and can also switch between living planets. According to computer simulation models, the process of creating similar life on Earth can also occur on other star systems that have planets orbiting stars.

To practical efforts

To search for alien life, people use two popular ways to search directly and indirectly. Immediately bring the detector up to the suspected planet to detect, and indirectly detect through radio waves, telescopes . Currently, self-propelled robots on Mars have many times send pictures that are supposed to be UFOs, aliens or animals .

The findings of self-propelled machines also reinforce the hypothesis that the red planet has water, or once had water, at least once there was life. A regular survey conducted at a European Space Agency conference showed that 75% of participating scientists believe that life once appeared on Mars, while 25% of scientists believe there is still life on Mars.

Since 2007, scientists on Earth have captured 18 Fast Radio Burst (FRB) signals. In particular, it is worth noting that the 6 FRB signals were captured from the same place named FRB 121102 in the Auriga galaxy, 3 billion light-years from Earth. Each signal lasts only a few milliseconds, so it is classified as a fast radio wave pulse.

Although scientists have identified the location of the FRB, their origin remains a mystery, but the researchers say that such repetitive signals are clearly not a phenomenon. Once, like an explosion or a collision.

Where are they?

Based on the collected FRB waves, some believe that aliens are at FRB 121102 3 billion light years away. Meanwhile, many people believe that they are closer, somewhere in the galaxies near the Milky Way, in the Milky Way, or more closely in the solar system.

For example, earlier this year NASA scientists discovered seven more planets that could have life. These are planets similar in size to the Earth, in which 3 planets orbiting their parent star with adequate distance to have water flowing on the surface. These planets are 40 light-years from Earth, a distance close to astronomical standards, but equivalent to 40 million years moving at the average speed of a passenger commercial aircraft.

"This finding shows us that finding a second Earth is only a matter of time," said lead scientist Thomas Zurbuchen at NASA's press conference. 2.

However, some scientists argue that equating alien life with life forms on Earth, from there to search for aliens in the pursuit of environments suitable for Earth's life form is a short-sighted direction.

In particular, most life forms on Earth exist and grow on the basis of basic elements such as water and oxygen, but it is possible that alien life forms do not need water and oxygen to live. Recently, people discovered the bacterium Desulforudis audaxviator , also known as "yellow beak" , existed very deep, nearly 3km underground, in the environment without light and oxygen.

It lives entirely on radioactive sources emitted from uranium."This finding suggests that the ability of outer space organisms to survive, even to eat cosmic rays instead of light, oxygen and carbon. It can't be ruled out that such life can exist in other corners of the universe and somewhere, there are creatures using cosmic rays to survive " - researcher Dimitra Atri said.

Meanwhile, many people believe that aliens are "capitalized" in a place very close to us, the Moon itself. According to these people, the Moon is an extraterrestrial planet, based on the evidence of the Moon's composition and structure, which may be a product of modern technology and science. .

Others believe that aliens are not far away but are watching us. The support for aliens who are watching humans is the appearance of giant drawings in wheat fields (wheat circles) , especially popular in the UK.

Wheat circles have two characteristics that make researchers believe that they cannot be human or natural products: (1) There is absolutely no trace of vandalism; (2) molecular structure at the bending position in wheat stalk is influenced by the electromagnetic field that crystallizes, but continues to grow normally.
