The plane that disappeared for many years actually appeared in outer space. What's going on?
In the previous article, we talked about such a thing. On July 2, 1955, a flight 914 took off and carried passengers for 35 years. Thirty-five years later, on September 9, 1990, they landed at the Venezuelan airport in South America. Before this, many people thought the plane crashed. Unexpectedly, not only did they return safely, but the faces of the passengers on the plane remained unchanged for 35 years. This incident used to be so loud that many people believed that the plane had passed through. However, over the years, with the development of the Internet industry, people gradually discovered that this was fake. It's just a man-made story. For the specific details of this incident, interested friends can go back to the previous article, and the content we are going to talk about today is also related to the aircraft. The difference is that the aircraft did not pass through, but appeared in outer space.

The density of neutron stars
Neutron stars are extremely dense planets in the universe. Even according to the most conservative estimates, the density of neutron stars can be as high as 100 trillion tons per cubic meter, which, it must be said, is unimaginable, so why do neutron stars exist at such high densities? Let's take a look at how empty the atoms are.

Fuji, Japan
As the largest volcano in Japan, Mount Fuji has successfully become one of the iconic business cards of Japan with its "superb beauty". Although it is a volcano, the top of Mount Fuji is covered with snow all year round, and from a distance, it looks like a dignified "Snow Queen".

Acacia trees and giraffes
Amid beautiful nature, there is a cold law: if a species cannot adapt to the complex and changing natural environment in time, it will be ruthlessly eliminated.

Earth's "twin brother"
Even though there are many celestial bodies in the universe, there are only a few like Earth that can nurture life. The resources on Earth are limited, and it will one day reach the limit of the life it can carry. The search for a second home has become a special mission, not just for one person, but a challenge for all mankind.

Another "Super Earth" discovered
The Sun is only one of the countless stars in the vast universe, and ever since this knowledge was gained, people have been speculating that other stars in the universe have their planets, just like the Sun.

Theories you can't accept
The emergence of scientific theories has largely contributed to the development of human civilization, which also contains many incredible theoretical contents, although their truth has been proven, many people still feel unacceptable.

If the sun suddenly disappears
What would happen to the Earth if the sun suddenly disappeared? The answer is, of course, the Earth will undergo great changes, but at the moment of the disappearance of the sun, the Earth will not immediately change, because the speed of propagation of the sun's light and gravity is the speed of light, about 300,000 kilometers per second, and the average distance between the Earth and the sun is about 150 million kilometers, so in about 500 seconds, the Earth's great changes will begin, and from then on the prelude to the difficult survival of mankind.

The world we live in could be a virtual broadcast
Our human perception of the outside world is the result of our brain's processing of various bioelectric signals, for example, our visual system will convert the external light into bioelectric signals, and then these signals will be transmitted to the brain, after the brain's processing, we "see" the external situation, and similarly, our Hearing, touch, smell, and taste are also produced in this way.
