When the meteorite falls into the earth, it will rub against the earth's atmosphere and burn. If the meteorite is large enough, then we will be able to see a flying fireball.
In this case, if we throw a raw egg down while flying on an airplane, will it turn into a mature egg when it lands? This is an interesting question, but you should never try to do this experiment yourself, because it will be very embarrassing when you take a raw egg on a plane and find that you can't open the window. This problem is destined to be solved only through thought experiments, because even if you can throw the egg down, there is no way to find the egg on the ground, and falling objects from high altitudes is an extremely dangerous thing. To know whether eggs can be cooked by throwing them from a plane, you first need to know how high the plane flies.
The cruising altitude of civil aviation aircraft is approximately between 8,000 meters and 12,000 meters. Let’s calculate it based on 10,000 meters.
The earth's atmosphere can be divided into troposphere , stratosphere, mesosphere and thermosphere from bottom to top. The altitude at which the aircraft cruises happens to be the bottom area of the stratosphere. This is because the airflow in this area shows horizontal flow. , relatively stable and conducive to the safe flight of the aircraft. Although the airflow in this area is stable, the temperature is very low. Because the earth's temperature mainly comes from the solar energy received by the surface, the farther away from the surface, the weaker the surface radiation received and the lower the temperature. In the stratosphere, At the bottom, the temperature can reach about minus 40°C. It's a challenge to throw eggs at such low temperatures. When we were young, when we wanted to eat fried eggs, there was a very convenient way to do it, which was to turn down the temperature of the refrigerator.
The old-fashioned refrigerator has a single door, and the seal between the freezer compartment and the refrigerator compartment is not tight. If the refrigerator temperature knob is turned to the lowest, the temperature in some areas of the refrigerator compartment will be as low as 0℃.
Put the eggs in these low-temperature areas. It won't take a while before the eggs will crack. So without saying a word, a plate of eggs will be born at lunch. Eggs are very sensitive to low temperature. As long as the temperature is lower than 0℃, they may be frozen to crack. So when we throw an egg out of the plane, the low temperature of minus 40℃ will freeze it to crack instantly. However, we do not Don't worry about the egg liquid spilling out, because the entire egg is already frozen at this time. After that, the cracked egg will fall rapidly, and the speed will continue to increase. The heat generated by friction with the atmosphere will eventually melt the frozen egg.
Because the eggs have been frozen and cracked, they will break quickly after melting, and eventually no residue will be left.
Fortunately, what we are doing is a thought experiment, so we can have an egg that will not be frozen. Can this egg be cooked during the fall? No, because the height is not high enough. Falling from an altitude of 10,000 meters does generate heat due to friction with the atmosphere, but this heat is too small to cook the eggs at all. The heavy rains in summer fall from an altitude of about 5,000 meters. Not only do they not turn into boiling water, they don't even use any heat. Of course, the egg is a little taller and a little faster than a raindrop, but it's still not fast enough to cook it. Eggs fall faster than rain? certainly.
Objects with different masses fall from the same height at the same speed. This is for an ideal environment in a vacuum.
In reality, objects falling will be subject to atmospheric resistance, and objects of different volumes and shapes experience different amounts of resistance. As the speed of the falling object gradually increases, the resistance also increases. Finally, the resistance and the falling speed are balanced, and the speed no longer changes. The speed at this time is called the terminal velocity. The terminal speed of objects with different volumes and shapes. The speeds are different, so the eggs fall faster than the raindrops.If eggs cannot be cooked by throwing them from a plane at an altitude of 10,000 meters, is it possible to throw them from space? If an egg is thrown from a spacecraft in Earth orbit, the egg will have the same speed and direction as the spacecraft, so it will orbit the Earth without falling. .
Assuming that the egg is not thrown from a spacecraft in earth orbit , but flies towards the earth at high speed from distant outer space, then it can successfully enter the earth's atmosphere.
Like other meteorites, it will have intense friction with the earth's atmosphere, and will gradually carbonize and decompose into particles during the friction. In fact, a large number of meteorites fall into the earth's atmosphere every day, and very few of them can actually reach the ground, because most meteorites will disappear due to friction with the atmosphere, and only those who are large enough can survive. When it comes to the ground, meteorites are like this, let alone eggs. However, we believe that this egg should have turned into a cooked egg before it was broken down into particles. Unfortunately, no matter where this egg is thrown from, it is definitely impossible to eat it.
