It is possible for the temperature to rise to thousands, millions or even trillions of degrees. However, when it comes to cooling, we cannot see below -273 °C. Today we will look at the mysterious limits of warmth.
Heat; It is something we feel in every aspect of our daily lives. Warmer in summers and colder in winters, temperature is one of the most basic concepts in our lives. This concept, which is so much in our lives, boundaries Understanding has always been important.
When you look at the temperature-related values before, the lowest temperature It can drop down to -273 °C. did you ever notice? When we look at high temperatures, the temperature 1 billion °C And we see that it can even go above it. So why is the lowest temperature so close to our optimal levels, while the highest temperature can be much higher?
The temperature of -273 °C corresponds to absolute zero.
Unlike the high temperature, we have much more information about the temperature that can be the lowest. According to the laws of physics The lowest temperature at which an object or substance can fall is -273 °C. This corresponds to 0 Kelvin or absolute zero.
So why can’t we go lower than this temperature?
The temperature of an object is actually caused by the movement of molecules. So the faster the molecules, the higher the temperature. On the other hand, -273 °C corresponds to the temperature where these molecules cannot move any further and are almost frozen. Since there is no reason to slow down a molecule that has already stopped, the temperature cannot drop below -273 °C.
Since we are so close, can we reach -273 °C continuously?
Just because a number is close to us doesn’t always mean we can reach it. Raising an object at 0 °C to 273 °C is not the same as lowering it to -273 °C. In fact, humanity has not yet reached the temperature of -273 ° C. The lowest temperature record that humanity can reach was only a fraction of absolute zero. To put it exactly, the temperature achieved was 0.006 Kelvin.
Let’s warm up a little. What is the highest temperature in the universe?
We have seen that the limit of low temperature is found very clearly. in many parts of the universe of a symmetrical structure We would expect it to happen, but there is no such thing in temperature. So what could be the highest temperature in the universe? In fact, scientists still have not discovered the limit of this temperature that can be reached.
The highest temperature ever created in the lab was 5 trillion Kelvin.
Large Hadron ColliderThis experiment, done in , appears to be the temperature of the baby universe a few minutes after the Big Bang. The Celsius equivalent of this temperature is “4,999,999,999,726.85 °C.

Could it get even hotter?
When it comes to temperature, things can get out of control. Scientists today an “absolute limit” to define the limit of temperature, such as absolute zero they haven’t discovered yet. For example, this value may be 10,000 times hotter than the 5 trillion Kelvin obtained in the laboratory.

The only limit that can help us at this point Planck scale it could be. This unit of measure is based on physical constants and is based on that obtained in a particle accelerator. It shows us that temperatures can be reached 100 billion times higher. However, according to most scientists, it is not possible for the temperature to reach such high values.
Today, we explained to you why the temperature cannot go below -273 °C while it is possible to reach billions or even trillions of degrees. If you want more content like this, you can write to us in the comments section.
