"Science"

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

The more "nucleons" an atomic nucleus contains, the greater its mass, but scientists have found that the average mass of the "nucleons" of different elements is different

Since gravity is actually a manifestation of gravity, and the magnitude of gravity is proportional to mass, for those objects with smaller masses, their own gravity is smaller

It has long been discovered in practice that the phenomenon of "gravitational time dilation" does exist

If mankind can master the method of extracting uranium from seawater in large quantities in the future, there will be enough uranium on the earth to last for tens of thousands of years, even hundreds of thousands of years!

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

In the evolutionary history of human beings, the gradual increase in brain volume is an important marker

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

The energy released by nuclear fusion is actually an important basis for stars to be able to maintain their stability

In essence, sound is actually a wave generated by the vibration of the object, the sound waves in the air is actually a "longitudinal wave"
