NO it is not in theory
The coldest temperatures ever to be reached have been in making Bose-Einstein condensates (tiny clumps of super-cold atoms) which requires cooling to something like 200 nano-kelvins -- mere billionths of a degree above absolute zero.
But to go all the way to zero implies complete lack of particle energy. According to the principles of quantum mechanics, there MUST always be some activity representing energy and therefore a temperature above absolute zero. For example, electron-positron pairs may be created out of vacuum.
Currently, achieving absolute zero (0 Kelvin) is not technically possible due to the Third Law of Thermodynamics. As we cool a system to lower temperatures, the energy required to do so exponentially increases, making it practically unattainable. However, scientists have approached very close to absolute zero in laboratory settings.
No, absolute zero is not something we can achieve. The reason lies in a simple idea included in the tird law of thermodynamics. That sets the bar very high, or low, if you prefer.
To take energy out of a system, you have to "surround" it with a system of less energy. That's because it is essential (required!) that there be a "low energy" place for the energy being removed from a system to go. If a system is to be "reduced" to absolute zero, it must have an absoulte zero system around it to have some place for the energy in the system being investigated to go. It's a catch twenty-two situation. And something we cannot do with anything close to the technology we have now. Use the link below to make a quick review of the third law of thermodynamics and how it applies to this situation.

Is absolute zero is equal to -273 degrees on the Kelvin scale?
Kelvin is defined in such a way that absolute zero is zero Kelvin.Kelvin is defined in such a way that absolute zero is zero Kelvin.Kelvin is defined in such a way that absolute zero is zero Kelvin.Kelvin is defined in such a way that absolute zero is zero Kelvin.
Is the speed of molecules at absolute zero temperature becomes double?
No, the speed of molecules at absolute zero temperature is zero. This is because at absolute zero, there is no thermal energy present to cause the molecules to move.
Why can't -5K exist?
0K is absolute zero, meaning that the system contains zero thermal energy. Temperatures below absolute zero are impossible.
Use absolute zero in a sentence?
Absolute zero is the lowest possible temperature, at which all particle motion ceases.
What is the zero point on the absolute scale defined as?
The zero point on the absolute scale is defined as absolute zero, which is the lowest possible temperature where particles have minimal motion and all thermal activity ceases. This corresponds to 0 Kelvin or -273.15 degrees Celsius.
What are the advantages and the disadvantages of absolute zero?
Advantages of absolute zero: It is a key reference point for measuring temperature and allows for scientific investigations into the behavior of matter at extremely low temperatures. Disadvantages of absolute zero: Achieving and maintaining absolute zero is extremely difficult and requires complex equipment. It is not practically attainable in most real-world scenarios.
What is the absolute vaue of zero?
The absolute value of zero is zero.
What is the special name for zero degree Kelvin?
Absolute zero.
The absolute value of zero is?
Zero.Zero.Zero.Zero.
Is zero degrees Kelvin absolute temperature?
It is absolute zero.
Is absolute zero is equal to -273 degrees on the Kelvin scale?
Kelvin is defined in such a way that absolute zero is zero Kelvin.Kelvin is defined in such a way that absolute zero is zero Kelvin.Kelvin is defined in such a way that absolute zero is zero Kelvin.Kelvin is defined in such a way that absolute zero is zero Kelvin.
Why is absolute zero important?
absolute zero is the essence of nothing and nothing is a quantity of zero.
Why is zero kelvin not attainable?
Zero kelvin represents absolute zero, the lowest possible temperature where particles have minimal energy. Achieving absolute zero requires removing all thermal energy from a system, which is practically impossible due to the third law of thermodynamics. As particles would need to come to a complete stop, the process itself violates the Heisenberg Uncertainty Principle.
Can an numbers absolute value be zero?
The only number whose absolute value is zero is zero. This is because a number's absolute value is its distance from zero on the number line.
Can absolute value be zero?
The absolute value of zero is zero. The absolute value of any other real number - or even of any other complex number - is different from zero.
Can an absolute value be zero?
The absolute value of zero is zero. The absolute value of any other real number - or even of any other complex number - is different from zero.
When was Absolute Zero - novel - created?
Absolute Zero - novel - was created in 1978.
