How small is the electron? If the Earth shrinks to the size of an electron, how big would the universe be?
In the macroscopic world, the earth moves around the sun, while in the microscopic world, electrons move around the nucleus of an atom. Although the two move in very different ways, we often associate the earth with electrons, so the question arises: If the earth shrinks to the size of an electron, how big would the universe be after shrinking in the same proportion? To answer this question, first, we need to know the size of the electron.

The farthest star from the sun, the identity of the mysterious "Sedna" where exactly from?
As we all know, there are 8 planets in our solar system, but before 2006, Pluto was also one of the big planets in our solar system, but, because scientists discovered another object called "Sedna" at the edge of our solar system in 2003, it was judged by many scientists to be a dwarf planet, but Sedna is much bigger than Pluto. This makes the real identity of Pluto once again suffer from questioning, finally in 2006 was dismissed by scientists, the real identity also from a large planet relegated to a dwarf planet. So, what is the origin of Sedna that made Pluto expelled?

The Yellowstone volcano, which is a great threat to humans, has been unusually active in recent years, and will humans become extinct once it erupts?
Introduction: With the advancement of technology, humans can master more and more things. But the only thing that is beyond human control is nature, and humans can only predict the occurrence of natural disasters. Once a natural disaster occurs, the consequences will be unimaginable. Today we are talking about the most terrible kind of natural disaster, that is, volcanic eruptions. One of the largest supervolcanoes in the world is known as the "Yellowstone Volcano". Even known as the active volcano in big brother, its area reached more than eight thousand square kilometers, larger than some small countries. Once the Yellowstone volcano eruption, human beings are very likely, in danger.

The Soviets tried to drill through the earth, and drilled to 16,262 meters why they stopped drilling down?
Nowadays, human beings are exploring more and more deeply into the unknown, our human Voyager vehicle is about to fly out of the solar system, which is already very far away from the Earth, and the Moon has been logged many times, and several planets near the Earth have been approached by man-made probes, human beings have made great achievements in exploring space, but human beings do not know the Earth very well, for example, what will be under the earth that we step on? Now the internal structure of the Earth is only a speculation, and no man-made probes have gone in, so many things can not be easily concluded.

The water in the Marianas Trench is crystal clear, but the magic is that as long as more than 100 meters below the seafloor, vision will be weakened can not see what the bottom of the sea looks like, vision is extremely limited, and there was a hair over the explorer set a record of - 113 meters. Why say below 100 meters vision is still blurred it, the reason is the role of the human's magnetic field, as long as within a certain depth, humans began to hallucinate, began to lose their way, for divers, down to the bottom of the sea must have contrast things to distinguish the direction.
