The Dhaka Times Desk When you think of the word space and close your eyes, you see a vast void. That emptiness has no end. Where many mysteries exist. What is the temperature of this space? That question is on our minds.
One thing always seems to pass by. And that is the measurement of space temperature. Although not constantly discussed, temperature, like everything else in a changing universe, is subject to evolution (moving from one position to another or stratification).
Experts and scientists have analyzed this topic in detail. It is still being tested.
A big question comes to mind all the time, that is how the temperature of the space is measured, how can it be measured? The only name that comes to mind immediately is the name of thermometer. It is not with the help of which we measure our body temperature. If we are sick, even if we have a fever, our body temperature rises! In the case of many inert objects, the temperature depends on the motion of the particles of its constituents. Take water for example. When the speed of water molecules is too low, it turns into ice. As the speed increases, the rotating particles also collide and heat is generated.
Then the water becomes liquid. When the speed of the particles also increases, the water starts to boil. Astronomers use electro-magnetic radiation as a thermometer. The shorter their wavelength, the warmer their source.
Like the Big Bang. It is a primordial explosion which is a fairly common definition. It is because of a huge explosion 14 billion years ago that this huge space was created. An unimaginably hot gas was created. From this gas, galaxies and cosmic objects are born in the universe. At that time various temperatures were created.
Stars like our Sun also have highly dynamic and powerful magnetic fields. Those fields can also speed up the particles at extreme rates. That is why the temperature of our surrounding environment reaches several hundred thousand degrees Celsius. Black holes have higher temperatures. Its gravitational force pulls all elements and particles into vapor.
It is known that extremely cold temperatures of around minus 270 degrees prevail in the interstices of galaxies, stars and planets. There are also relatively few and slow moving particles. Because of this, conflicts between them are also rare. Moreover, the universe is expanding. Due to this expansion, the distance between the particles also increases gradually. As the distance increases, the temperature also decreases.
According to a news report, Europe's Planck satellite measured that cold temperature very precisely a few years ago. Astronomers can measure and examine radiation at all wavelengths with telescopes in space. By measuring the radiation source and its density, they determine the temperature of the source.
