Is there a color that humans have not yet discovered?
In 1666, Newton discovered the different frequencies of color light through a trigonometric mirror, and people gradually realized that the light we perceive comes from a combination of compound light, and the different colors we can perceive are related to the reflection of different colors of light. From the current situation, there are more than 1 million types of colors that can be seen by humans with normal eyesight and vision (women can discriminate 50 colors higher than men), so is there a color in the world that humans have not yet discovered?

The Alps are turning green
The Earth is changing, not only in human habitats but also at the North and South Poles and in high mountain plateaus far from humans. And many of these changes are to a large extent related to us humans, and we humans are responsible for some of the changes on the planet. Because it is our human activities that cause these changes to occur, or we exacerbate the rate of these changes.

Mysterious dark matter 12 billion years old
Dark matter is the most mysterious presence in the universe, and although we cannot see it directly, there are some clever ways to deduce that it should be far more abundant than ordinary matter. The existence of dark matter is crucial to the evolution of the universe. In a recent study, astronomers have mapped how dark matter was distributed around galaxies some 12 billion years ago. Their findings suggest that dark matter is less aggregated than theories would expect.
