Can you make wormholes on the earth?

  In theory, the ends of the wormhole are black holes, so if you want to make a wormhole, you need to make a black hole first. Humans can create a tiny black hole by artificial gravity and then create a wormhole through a black hole. However, it is not easy to make a black hole. It is estimated that if you want to make a black hole with a diameter of 1 cm, you need to compress the size of the earth to a size of 1 cm. On the one hand, it is obvious that the Earth cannot be placed with the same size as the Earth. On the other hand, it will require enormous energy to be realized, and human technology is far from being able to do so.
  Even if humans make wormholes, consider the stability of wormholes. According to the scientist’s theory, the wormhole is very unstable. If you want to maintain its state, you need to use the “stabilizer”, which is a substance predicted by quantum theory. This substance may have an antigravitational effect that prevents the wormhole from collapsing. But no one knows what this substance is and how to operate it to maintain wormhole stability. Therefore, human beings cannot create wormholes on the earth.

Why does a smell disappear after you get used to it?

  The sense of smell is the brain’s perception of odor. When we smell a fresh smell, we are happy. When we smell bad smell or other irritating smell, we will be alert to the danger in our surroundings. When odor molecules stimulate the sensory olfactory neurons in our nose, we can smell. Usually we are very sensitive to odors. Only a few odor molecules are enough to stimulate an olfactory neuron. The olfactory neurons send nerve pulses to the brain quickly, so that the brain processes the signals and recognizes the odor, causing us to smell.
  But the brain will have a feeling of adaptation. When the same smell continues to stimulate, the brain will feel “fatigue”, adapt to the smell, think it is not dangerous, and stop recognizing it, reduce or stop receiving the smell. Stimulate the repetitive information generated. Olfactory neurons also adapt to the stimulation of persistent odors by reducing the rate of discharge. Therefore, we feel that the smell is disappearing. The advantage of this is that the olfactory neurons and the brain can work in the identification of other odors in the environment without repeating the useless work. Sensory adaptation is not only found in the sense of smell, but also in touch, sight, hearing and taste.

The earth’s magnetic pole is rapidly shifting, will the Northern Lights move?

  The geomagnetic pole has been doing irregular movements, but the magnitude is not very large. Studies have shown that the aurora moves as the magnetic pole moves.
  The Northern Lights are now visible mainly in Northern Europe, Canada and the North. Scientists have recently observed that the Earth’s magnetic field is moving westward. If the geomagnetic pole moves very rapidly, the aurora may move accordingly. According to predictions, if they move north, through geographical poles, and move along the North Pole, then Northern Lights will be seen more frequently in northern Russia and Siberia, while the chances of seeing Northern Lights in the United States and Canada will decrease.

Can we move the planet to a more livable track?

  In theory, the orbit of the planet can be changed, but in reality it may not be possible. In fact, scientists have been studying the technology of moving asteroids, mainly to remove the asteroids that hit the Earth. However, most of the technology is destructive, such as nuclear explosions near the planet or on the surface, high-speed impact on asteroids with spacecraft, etc. These methods are not suitable for moving the planet to a livable zone, not only because the planets are larger, but also because This can damage the planet. There are also some techniques that are more moderate, that is to pull the asteroid to the designated position, but this requires a long time to provide power, mainly from the tugboat docked on the surface of the asteroid, or by a spacecraft hovering around it, through gravity or other Method push. In terms of human technology, moving a planet is almost impossible.

Why are ants not getting fat?

  In fact, some ants will get fat. For example, a member of the honeypot ant called “sweet honey ants” that absorbs a large amount of sugary liquid every day and stores it in the body. When other members of the ant colony need it, they will take the sugar liquid. Give it to everyone. When the sugar liquid is not stored, the body of the stored honey ants is small, but after the body is filled with sugar liquid, they become round and round, several times larger than other members.
  The average ant usually keeps his body in his life, which is related to how much they eat. The ant has two stomachs, one for the food that guarantees its own nutritional needs while eating, and the other for the rest of the food for hunger. If the companions ask for food from them, they will also unselfishly spit out their stored food for some to eat. More importantly, ants have no lungs and can only “breath” through a small tube. If they grow up and their heads become larger, they will need to consume more oxygen, which is not worth the candle.

Why are the volcanoes on Mars so much higher than those on Earth?

  This is related to the environment of the two planets. Mars’ surface gravity is only two-fifths of the Earth’s, and the same height, the volcano on Mars is less than the gravity on Earth, which makes them less prone to collapse. Some scientists have done calculations. When the mountains on the earth exceed 15,000 meters, the mountains may collapse because they cannot withstand the pressure; and the mountains on Mars can theoretically grow to more than 37,500 meters.
  Moreover, there is no plate movement on Mars, which means that the heat inside Mars can only be concentrated from the volcanoes distributed in hot spots, and the continuous accumulation of lava makes the volcano higher and higher. Mount Olympus, which is more than 20,000 meters high, is formed by a large number of lava eruptions and lava stacks. The volcanoes on the earth are distributed in the form of volcanic belts. These volcanic belts cover a wide area, and the heat inside the earth can be released from any volcano. The lava will not be concentrated around some volcanoes.
  In addition, the atmosphere on Mars is thin, the weathering rate is very low, and the volume of the mountains is not reduced by weathering. The weathering on the earth is serious, and the mountains will gradually be “shortened” by the wind and rain.
