"earth"

Although we do not know much about these two "super Earths" yet, but from the basic situation, these two "super Earths" are not suitable for human habitation

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.

It is proposed that birds originated from dinosaurs, and that "ancestor birds" are a transitional species between birds and dinosaurs.

In the past days, scientists have been working on the study of meteorites, and as the research continues, there is more and more evidence that life should originate from outer space

Proxima, a slightly smaller red dwarf than Ross 508, has been frequently observed by astronomers as a giant flare in the past.

The earth's water resistance comes from the high temperature, pressure and density of its interior

The climate patterns on Earth will then become chaotic, and humans will lose the ability to control and drive the Earth's climate to remain stable and conducive to the habitability of humans and the Earth's biosphere as a whole

It has been billions of years since life appeared on earth, and although there are seven planets in our solar system in addition to earth, as well as a number of dwarf planets, moons and other relatively large bodies, so far we have not found alien life on any other planet in our solar system for the time being. Even mars, another earth-like planet in the habitable zone of our solar system, has not found a single sign of life. Could it be that life on earth is really unique and no other planet is allowed to have life?

In orbit for longer and longer periods of time, we need to solve not only inorganic resupply problems such as food, water, oxygen and propellant, but also the various problems faced by astronauts flying in orbit for long periods of time

If humans evolved from the forest archaeopteryx, how did the forest archaeopteryx emerge?
