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. It has always been important to understand the limits of this concept, which is so much in our lives.
When you look at the temperature-related values before, have you ever noticed that the lowest temperature can go as low as -273 °C? When we look at high temperatures, we see that the temperature can reach 1 billion °C and even above. 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 could reach was only a fraction above 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. We would expect a symmetrical structure to exist at many points in the universe, 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.
This experiment at the Large Hadron Collider 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 have not yet discovered an “absolute limit” that would define the limit of temperature, such as absolute zero, today. 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 may be the Planck scale. This unit of measurement is based on physical constants and shows us that temperatures can be reached 100 billion times higher than that achieved in a particle accelerator. 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.
