1、 Spinach leaves grow into human heart tissue
Popeye’s favorite spinach is expected to become the second heart of humanity. After multiple experiments, scientists injected cleaning agents into spinach leaves to remove plant cells and grow beating human heart cells on the leaves. Researchers suggest that this concept validation suggests that spinach leaves may be used to cultivate healthy heart muscles and help treat heart disease patients. The team even believes that after injecting blood into spinach leaf veins, cellulose can transport blood and oxygen to the developing heart tissue.
2、 The Earth is not the center of the universe
We have spent over 400 years denying the “geocentric theory”, but the statement that “the Earth is not the center of the universe” still confuses us at times, because everyone clearly sees the sun and stars rising from the east and setting from the west, and our Earth is as stable as a rock. When Copernicus proposed that the Earth and other celestial bodies revolve around the Sun, most of his contemporaries believed that his logical thinking was absurd, and only a few scholars agreed with his viewpoint. For this theory, Galileo paid a greater price than Copernicus.
3、 The universe is composed of unimaginable matter
When you think of the universe, all you can think of are stars, galaxies, black holes, and dust. However, these only account for 4% of all matter in the universe, while the rest exist in two “dark” or “unclear” forms: dark matter accounts for 23%, and dark energy is as high as 73%. It is precisely because of the existence of dark energy that astronomers are convinced that the universe is constantly expanding, not just expanding, but also at a faster speed, causing all objects in the universe to be further apart. In the end, the universe will become a cold and desolate place. This world will come to an end in sobs.
