View source for Zero-point energy

[[Category: Physics]]
== Explanation ==
Zero-point energy is the [[energy]] of a system when it is at its lowest energy state. The reason for the energy can be explained with the [[uncertainty principle]]. Every system obeys the uncertainty principle, which is when the position of a system is known, the momentum of the system cannot be known for sure, and vice versa. So at its lower energy state or the ground state, the system should have a minimum energy to satisfy this principle. That energy is the zero-point energy.
== Frequently Asked Questions ==
=== Is it possible to draw the zero-point energy out of the system? ===
No. This would violate the uncertainty principle and thermodynamic laws. Therefore, such a system is impossible to exist in the universe.
