Will humans never be able to fly out of the solar system? Voyager blocked by 'wall of fire' with 50,000°C temperature
Can humans fly out of the solar system? This is a question that is of great concern to everyone. It has been more than 40 years since Voyager 1 and Voyager 2 flew off the Earth, so long that many people thought Voyager had flown out of the solar system, but the reality is just the opposite.

An Earth-like planet four times larger than Earth has been discovered, less than 11 days a year, and may have life
Is there extraterrestrial life in the universe? To answer this question, we first need to see if there is a planet like our Earth that can provide conditions for the existence and development of life. This is also because so far scientists have found life only on Earth. Although astronomers have used many huge astronomical telescopes to look at the universe and launched deep space probes to probe in detail for extraterrestrial planets, they still have not found any life forms beyond Earth.

Why did Stephen Hawking repeatedly discourage humans from using the eye in the sky and what did he actually discover?
Once upon a time, the moon was far away, but now we can travel to the moon and leave human footprints on it. Once upon a time, people saw Mars as an ominous omen, but now when they set foot on it, they realise that Mars is a barren planet. A misconception has been created because the topsoil contains a lot of iron, which causes the soil to be reddish.

Apollo 18 mission, found on the back of the moon 100 million years ago spacecraft, is it true?
Introduction:From the beginning of the industrial revolution to the present, the level of human technology has also been improved by leaps and bounds. A long time ago, human beings explored outer space, the earliest was the exploration of the moon, because the moon is the closest celestial body to the earth. 2008, photos about the moon caused a hot debate on the internet, in which the spacecraft-like objects also gave rise to exaggerated ideas.

Why is the US in a hurry to return to the moon? The moon turns out to be a "big reservoir"!
Decades have passed since the United States abandoned the moon landing in the last century, and now it has been announced that it will do so again this century. There is some curiosity as to the reasons for this. One wonders why the US is restarting its moon landing program. It has never been a principle that the United States lives by, never doing anything that is not profitable, so most people think that the United States must have found something profitable on the moon. What could it be?

Resurrection from the dead technology is maturing, immortality may be possible? The technology is highly questionable!
In the plots of science fiction movies, we sometimes see scenes of "coming back from the dead", but does "coming back from the dead" exist in real life?

Do extra dimensions exist in the universe? Why do scientists want to prove multidimensional space?
Einstein's theory of relativity proposed that the universe is a four-dimensional space-time consisting of three-dimensional space and one-dimensional time.

Evidence of 'Pac-Man' black hole devouring neutron star detected by scientists for the first time a billion years ago
A black hole, known as the "Pac-Man" of the universe, is by far the most terrifying and dangerous being in the universe that we know of. It captures all matter in its vicinity with its powerful gravitational force, and not even "light" can escape. At the same time, its mystery has attracted the attention of countless astronomers, hoping to learn more about it.

Hawking left three pieces of advice before he died, people dreaded the first and the third has already happened
Stephen Hawking was one of the world's greatest physicists, but he has left us. Stephen Hawking died at his home on 13 March 2018 at the age of 76. Hawking's death has left many people feeling sorry for him. Many wish that Hawking had not left us so soon, as he could have taken us on a journey to understand the universe and space from more perspectives.

Scientists discover metal-eating creature, expert: can eat nuclear waste, great use
Microbiologists from the California Institute of Technology have published their findings in the journal Nature. They have discovered bacteria that feed on Meng. These organisms can directly metabolise and absorb substances that seem completely impossible to us, such as metals, and such organisms that use metals to power themselves happen to exist in nature.

Vaccines: everyone has had them, but not everyone understands them!
First, let's understand what vaccines are. How many types of vaccines are there? A vaccine is a biological product made from various pathogenic microorganisms (bacteria, viruses, tumor cells, etc.). Vaccinations are administered. In addition, the use of bacteria or spirochetes to make a vaccine can also be called a vaccine.

Haunted beds: a nightmare that hits multiple human weaknesses! So you get scared!
I'm sure many people have had the experience of waking up suddenly, only to find that they can't move or even make a sound, but their sense of sight and hearing have become more acute than usual. At this point fear ensues, perhaps because of the visual or auditory senses, but more likely psychologically. This is called ghost pressure, also known as nightmares.
