Science and art are two sides of a coin
what is the principle of flight of the dragon?
The dragons discussed in this article are not the brontosaurs that lived tens of millions of years ago, nor are they the flying and fire-breathing dragons of Western legends, but the dragons of Chinese legends. In contrast, both the brontosaurs and western legendary dragons had wings, and it is not surprising that they could fly, while the Chinese legendary dragon is much more powerful, because this amazing creature does not have wings, but can still fly in the sky.
Astronomers: Senkaku IV was pierced by a mysterious force before it became dark
Every shining star in the universe will be extinguished one day, and its "lifespan" is closely related to its mass. For example, Proximal is about 12.2% of the Sun's mass, and its "lifetime" can be as high as trillions of years, while the Sun's "lifetime" is only about 10 billion years, and those stars are much larger than the Sun, its "lifetime" is even shorter.
The world is virtual?
Our human perception of the outside world is the result of our brain's processing of various bio-electric signals generated, for example, our visual system will convert the external light into bio-electric signals, and then these signals will be transmitted to the brain, after the brain's processing, we "see" the outside world, the same, our Hearing, touch, smell, the taste is also produced in this way.
Is the sun suspended in the universe?
We often imagine the solar system as follows: the sun is at the center of the solar system without moving, while the eight planets and many other celestial bodies in the solar system are orbiting around the sun in an orderly manner, and the earth is also a member of it, which begs the question, is the sun suspended in the universe?
70,000 years ago, our solar system was invaded by stars
The Milky Way is a huge galaxy with hundreds of billions of stars, and the Sun is just one of the not particularly impressive stars, which, together with many stars in the Milky Way, are orbiting around the center of the galaxy, such a situation does not prohibit us to worry about the number of such a huge number of stars in constant motion, over time, the Sun will not hit other stars?
Incredible! The moon may have formed in just a few hours.
Among the many natural moons in our solar system, the Moon appears to be quite different, with a mass of about 1 in 81 of the Earth and a diameter of about 27% of the Earth. A natural moon like the Moon is too large for a rocky planet like Earth, and this strongly suggests that the Moon probably has a distinctive origin.
In 1908, mankind was lucky to escape a disaster. Scientists: only 10 km short
The universe is full of all kinds of dangers, even on Earth, which is known as the "paradise of life", we still face threats from outer space, such as those in the solar system, "wandering around" asteroids, from time to time close to Earth, and If they hit the Earth, it may bring a disaster to mankind.
Beneath the light of Sirius lies a dangerous celestial body
Sirius is the brightest star in the night sky, and its great name is also known to us, but perhaps you do not know that under the light of Sirius, there is a dangerous celestial body hidden, which may threaten the Earth in the future, let's take a look at the specific situation.
The deepest seafloor has a pressure of over 1000 atmospheres, will the mud here be compressed?
About 71% of the Earth's surface is covered by the oceans, and we humans know very little about this vast area. As things stand now, human activity in the oceans covers only about 5% of the entire ocean water column. Why is this so? This is because for every 10 meters increase in the depth of the ocean, the pressure in the seawater will increase by about one atmosphere, while the average depth of the Earth's oceans is about 3795 meters, so it can be said that it is the strong pressure in the deep ocean that limits the ability of humans to explore the ocean.
The world's top 5 amazing facts: there were only 2,000 humans left, and Everest is not the highest peak.
The Earth has been born 4.6 billion years, scientists will be divided it into three stages the 4.6 billion years, the first stage for the formation of the period, the second stage to become the Pacific Ocean, the meta-Paleocene, the original atmosphere is formed in this period, the third stage for the geneticist zeros, biological, geological evolution began.
