What is life?

  What is life?

Life is actually the fastest mechanism of energy propagation in the universe. The dispersion of energy over time is called entropy. When sunlight hits the Earth, it is in the form of high-energy photons that we see, but when the Earth absorbs this light, it is refracted into 20 or more low-energy photons, called (intensity). The case is emissive (the total energy of an energetic photon absorbed and the photon of lower energy emitted is equal). Consider what would happen if the earth could not absorb the sunlight or energy and emit it again in the same amount? Let me draw your attention to an observation to understand this easily.

Today the weather is changing in Pakistan, winter is coming. A few decades ago, winter used to come early, but now due to climate change, the duration of winter is getting shorter and the summer season is longer, which is having negative effects on agriculture and agriculture and the country's economy is sinking.

 So let's go on a cold night when the cold wind is blowing outside and eat dinner for the purpose of relaxation

Enter the pleasure. Rezai will be cold in the beginning but after some time the temperature of Rezai will start rising? why so? This is because your healthy body keeps the blood circulating in you to keep you alive. Through which the glucose and oxygen in the blood reach your cells where they chemically react with each other to release carbon dioxide, water and energy. In order for this process to work properly, your body needs to keep itself at a certain temperature, which requires your body to release energy. If you put a thermometer in your mouth and you don't have a fever, the thermometer But the temperature will be 37 degrees Celsius.

why so ? This is because if the temperature is high, the cells in the body and the proteins in them will be damaged and if it is too low, the processes in the body will slow down. One of the possible reasons for this temperature is not giving the opportunity to bacteria and germs from outside to flourish.

 So your body is set at a certain temperature, about 37 degrees. This means that your body is hotter than the comfort you have entered to avoid the cold. Rezai's temperature will be the same as room temperature. And you will feel cold only when the outside temperature is lower than your body temperature. So low that the energy your body normally emits is immediately absorbed by the cold air molecules in the room. The lower the temperature outside, the faster energy will be released from your body. As if the cold molecules of the outside air would have the ability to absorb more energy. So what changed when you moved into Rezai to escape the cold?

: The cotton or wool in the rug will absorb the heat from your body and release it into the room air after a delay. Because of this, you won't feel cold in Rezai. As if the release of energy from the body into the air was slowed down by pleasure. Thus, it became a closed system where on one hand, energy is continuously flowing from your body to Razi, but there is little or no discharge from there, and gradually the temperature of Razi starts approaching your body temperature. Now imagine that if the sunlight falls on the earth, but the earth does not emit it again, then due to the sunlight falling on the earth for billions of years, the earth does not become embers and there is no life capable of living here?

 The Earth actually absorbs as much energy from the Sun as it emits back into space. However, the energy release process is somewhat slow.

This is due to the greenhouse gases in the Earth's atmosphere that slow down the energy released from the Earth, just as respiration prevents or slows down the energy released from your body into the air.

If there were no greenhouse gases in our atmosphere, the temperature on Earth would not be moderate and it would not be suitable for life.

Life is actually a rapid and orderly mechanism of energy diffusion. Your body stays at a certain temperature. Not at ambient temperature outside. For this you need constant food from which you get energy. With this energy you work, move,

: your body breaks down food. What is all this? It is the diffusion of energy in a systematic way. The breakdown of food, the birth of human beings, the birth of living things, eating each other, etc. Life is the propagation of energy over time.

If we accept this definition of life, we see that the entire universe is alive, that the universe is also continuously expanding, and that the energy distribution in it is also increasing with time. And if we take this definition of life, every star, every planet, every organized galaxy is alive. And the interesting thing is that all these stars, planets, galaxies were not formed at once by themselves, but all these stars, planets, galaxies were formed by the process of evolution of matter, just as we humans or other living beings are formed by the natural process of evolution. .
