For humans, the universe is too dimensional for us to see the details of its depths for the time being

Earthquakes are a common natural phenomenon. On average, millions of earthquakes occur on Earth every year, except that most of them are so mild that they are largely imperceptible to humans.

The modern Earth's atmosphere is so rich in oxygen that the vast majority of this hydrogen will be re-oxidized to water without escaping from the Earth's top atmosphere

In this 5.5 million-year-old cave, not only is there no sunlight, but the environment is also very harsh

In theory, when a civilization develops into a civilization that can cross the stars, there is basically no risk of extinction

When scientists conducted research in the Arctic Circle, they found some mysterious giant holes in the Siberian plain within the Arctic Circle.

Although ultra-pure water does not exist in nature, humans can prepare it themselves

There is a view that the reason why the Earth looks round is because of the role of the Earth's oceans, which simply means that a large amount of seawater has "filled in" the undulations of the Earth's surface.

According to some scientists, the earth itself did not exist billions of years ago, but about 4.6 billion years ago, a giant interstellar molecular cloud gravitationally collapsed to form the solar system. Some dwarf planets, moons, asteroids and other bodies that are somewhat smaller in size than the planets. This is how our home on earth was formed, but in the early days of its formation the earth was not as beautiful as it is today, the newly born earth was shown to be made up of magma, a boiling 'ocean' if you will.
