Where is the coldest place in the universe? The answer is the Boomerang Nebula (Boomerang Nebula), known so far as the coldest object, its temperature as low as minus 272 degrees Celsius, which cold people can not imagine.
According to a report on the Live Science website, astronomers have measured the temperature of the Jarabo Nebula through the Atacama Large Millimeter-submillimeter Array in Chile to be minus 272 degrees Celsius ( Or minus 458 degrees Fahrenheit), considered the coldest place in the universe.
About 5,000 light-years from the earth, in a young planetary nebula called the Jai Li Bang Nebula, there is a dying star. The nebula was created by this.
The Collapse of Star – The Start of A Cold Era
Over time, a star called a red giant would exhaust the hydrogen in its core and eventually collapse into a white dwarf, the very dense core remnant of the star.
The star’s outer layer will be thrown down when the collapse occurs. This is because the red giant is enormous and has weak control over the outer layer. When the light from the white dwarf illuminates the outer gas, it presents a brilliant planetary nebula to humans.
These gases expand outwards quickly, and their outward movement speed exceeds 585,000 kilometers per hour. As the gas expands, they become colder. This is because the expansion will cause the pressure to decrease, which in turn slows down the movement of gas molecules, and thus the temperature drops. (The kinetic energy of the gas molecules increases with temperature and accelerates movement pace and vice versa.)
That’s why Boomerang Nebula is so cold; even more than the universe’s big bang, cosmic background radiation left over from the (cosmic background radiation) is still cold.
The Coldest Place on Earth is In A Lab
As for the earth, the coldest place known so far is the Massachusetts Institute of Technology laboratory in the United States.
In 2015, a group of physicists at the school used lasers to cool individual sodium and potassium atoms to a temperature of minus 273.15 degrees Celsius, which is colder than the Pelagic Rod Nebula. However, this is only limited to some atoms and does not occur naturally.
The environment on earth is conducive to human living, and liquid water is permitted. The main reason is that the earth can receive the sun’s radiation, frequent movement inside the earth, and the surface is protected by the atmosphere. Without these necessary conditions in space, the temperature is naturally shallow. According to the laws of physics, absolute zero is minus 273.15 degrees Celsius (or can also be recorded as 0 Kelvin), which is a state that cannot be achieved in theory. The temperature is above absolute zero, even in a seemingly empty space.
Seeking Out the Coldest Place in the Universe To Build Better
The Cosmic Microwave Background (Cosmic Microwave Background) that permeates the universe makes the average temperature in space reach 2.725 Kelvin. So, where is the coldest place in the universe? Careful design is required to reach extremely low temperatures close to absolute zero. Humans have created the lowest known temperature in the universe in a laboratory on the earth’s surface. Lower temperatures may soon appear in the Earth’s orbit on the International Space Station. (International Space Station), this also marks another advancement in the human exploration of the nature of matter.
The standard material forms are solid, liquid, and gaseous. In fact, under some extreme conditions, the matter will show more peculiar states. For instance, certain atoms will take on a state more akin to a “wave” in the description of quantum mechanics when exposed to extremely low temperatures. In the 1920s, Indian physicists Satyendra Nath Bose (Satyendra Nath Bose) and Albert Einstein predicted that the boson atom, which can have multiple atoms of the same energy state, would exhibit a gaseous, superfluid state of matter at a temperature near absolute zero. This ideal state of matter is called Bose-Einstein condensate (Bose-Einstein condensate).
Final Thoughts on Seeking Out the Coldest Place in the Universe
So, we’ve covered a lot of ground in this post. What did you think? I’ll bet your thinking of that really cold winter you experienced wen you were a kid.
The coldest place in the universe is Boomerang Nebula, with a temperature of minus 272 degrees Celsius. That’s so cold that even if you were to go there you would die instantly and freeze to death. But if you were lucky enough not to freeze to death, then you would be frozen solid and unable to move or speak. You’d be trapped forever in a state of eternal frozenness!
So let’s recap: If you wanted to go somewhere where it’s really, really cold, then Boomerang Nebula is your best bet—but only if you have an extremely good reason for going there (and maybe some extra jackets).
