This would be a consequence of the 2nd law and the "zeroeth" law. Heat always flows from the warmer object to the colder one (2nd law), so to cool something down to absolute zero, you would have to have something colder than absolute zero to absorb the heat coming out. The zeroeth law, however, defines absolute zero as a ground state where energy has been reduced to its absolute minimum - thus you cannot go below absolute zero and thus there cannot be something to absorb the energy to take an object to system down to absolute zero.
The Second Law of Thermodynamics is equivalent to the Law of Conservation of Energy. The Law of Conservation of Matter is not stated in the laws of Thermodynamics.
The Third Law of Thermodynamics.
Nope, never, absolute zero cannot be reached by artificial or natural means.
Absolute zero is achieved when the atoms in a substance stop moving completely. At -273.15C or -459.67F. True absolute zero cannot be reached, but it can be approached to within a few millionths of a degree.
It can't be reached. However, scientists have managed to approach absolute zero within less than one microkelvin.
No, nothing ever can reach absolute zero. The reasons are scientific, but the lowest we've ever gone to is 450 picokelvin (that is 0.000000000045° kelvin).The third law of http://www.answers.com/topic/thermodynamics is an axiom of nature regarding http://www.answers.com/topic/entropy and the impossibility of reaching http://www.answers.com/topic/absolute-zero of http://www.answers.com/topic/temperature.
-273 degrees. This is called absolute zero or the point at which you cannot get any colder. It is theoretically impossible get colder than absolute zero.

Do you mean 'reached the concept of absolute zero'? I ask this because I was always told that you cannot reach absolute zero, because absolute zero is the the lowest temperature in the universe. It is like trying to go faster than the speed of light. It hasn't been reached, yet.

No, absolute zero is not possible to achieve. At absolute zero, a molecule would have no kinetic energy, therefore would be stationary. Quantum mechanics shows that this is impossible, as there is always fluctuations in kinetic energy. The earth's poles are way above absolute zero. Particles in space around around 2 Kelvin, which is extremely cold. The lowest temperature ever achieved on Earth was done in a laboratory with sodium atoms, which were cooled to just under 500pK.
it is zero on the kelvin scale, there is absolutely no particle movement, and it has never been reached
You cannot lower the temperature if you are at absolute zero.
- Nitrogen gas become a solid.- Absolute zero is intangible.
It is called "absolute zero", but it is theoretical - while it can be approached very, very closely, it cannot actually be reached.
Absolute zero is the theoretical lowest possible temperature. More formally, it is the theoretical temperature at which entropy reaches its minimum value. The laws of thermodynamics state that absolute zero cannot be reached using only thermodynamic means. A system at absolute zero still possesses quantum mechanical zero-point energy, the energy of its ground state. The kinetic energy of the ground state cannot be removed. However, in the classical interpretation, it is zero and the thermal energy of matter vanishes.
