Does there exist a state of zero total energy?

In summary, the speakers discuss the possibility of a physical circumstance with zero total energy, taking into account contributions from mass, spin, and other factors. While in principle a pure vacuum could have zero energy, any system including particles cannot have zero total energy due to the equivalence of mass and energy. It is possible to measure zero total energy, but this does not necessarily imply that the system has zero total energy when considering the Heisenberg Uncertainty Principle. The speakers speculate that it may be possible to have a circumstance where the uncertainty in energy is zero, allowing for a claim of zero energy.

Counting contributions from mass, spin, etc., is there a physical circumstance of zero total energy?

In principle, I don't see why there could not be a pure vacuum (a region containing zero energy).

But obviously, since even mass itself is equivalent to energy, any state including a particle cannot have zero total energy.

Can we make a measurement of zero total energy? Sure. Can we therefore imply that the system (or physical circumstance if you like) has zero total energy? I don't think so, not if you account for the HUP.

Could you get a circumstance where the uncertainty in energy is perfectly zero perhaps? Then it may be possible to claim a circumstance zero energy is possible.

Related to Does there exist a state of zero total energy?

1. What is the concept of zero total energy?

The concept of zero total energy refers to the state in which the total energy within a system is equal to zero. This means that all forms of energy, including potential and kinetic energy, have been completely balanced and cancel each other out.

2. Is it possible for a system to have zero total energy?

Yes, it is possible for a system to have zero total energy. This can occur in situations where the potential energy of the system is equal and opposite to its kinetic energy, resulting in a net energy of zero.

3. What are some examples of systems with zero total energy?

Some examples include a pendulum at the highest point of its swing, a charged particle at rest in a uniform electric field, and a simple harmonic oscillator at its equilibrium position.

4. What implications does zero total energy have in terms of the laws of thermodynamics?

The concept of zero total energy is consistent with the first law of thermodynamics, which states that energy cannot be created or destroyed, only transferred or converted between different forms. In a system with zero total energy, there is no net energy transfer or conversion.

5. How is the state of zero total energy relevant to scientific research?

The state of zero total energy is relevant to scientific research as it allows for a better understanding of the behavior and properties of physical systems. It also serves as a reference point for studying energy transformations and the laws of thermodynamics.
