What’s Negative Energy?

Negative energy is a scientific concept based on Heisenberg’s uncertainty principle and is a highly unpredictable force that exists in energy or magnetic fields. It was proposed by Dirac in 1928 and is usually not observable. The concept has been demonstrated in experiments, including the Casimir effect. It is speculated to exist on the brink of black holes and has been cited as a necessary prerequisite for time travel by Stephen Hawking.

While many know that “negative energy” refers to negative chi, negative aura, or otherwise harmful energy that a person emits, the term also has a scientific definition. Based on Heisenberg’s uncertainty principle, negative energy has to do with the inherent fluctuations of energy that exists in any energy or magnetic field. This form of “exotic matter” is a highly unpredictable force that has been shown to exist amid zero-energy fields. While difficult to identify, this type of energy is speculated to exist on the brink of black holes and has been cited as a necessary prerequisite for time travel by Stephen Hawking.

The concept of negative energy was proposed by British physicist Paul Adrien Maurice Dirac in 1928, as a component of the Dirac equation. This equation was designed to be consistent with the standards of special relativity. In this equation, Dirac described how quantum states of positive energy would be offset by negative energy. Generally, these two types of energy balance each other. Therefore, a form of negative energy is usually not an observable phenomenon. However, in the case of a pure vacuum, negative energy states will be expressed for all atoms within the vacuum while no positive energy states will be expressed. This concept is referred to as the Dirac Sea.

In theory, a hole can develop in the Dirac Sea if a stray gamma ray collides with electrons in a negative energy state, thereby converting it into a positively charged electron. Such a hole in the Dirac sea would behave oppositely to the original, negatively charged electron. The new positively charged electron would be an example of antimatter. Therefore, antimatter should not be confused with a negative energy state.

In 1948, the Dutch physicist Hendrick Casimir predicted that a small attractive force could exist between two parallel uncharged plates in a vacuum. If the plates are very close to each other, negative energy is produced as the number of electromagnetic waves between the two plates becomes less than that of the surrounding space. Basically, a negative energy state occurs when the wavelengths of the particles in a certain region of space are lower than those normally measurable.

Casimir’s predictions were observed in two separate experiments. The first experiment took place in 1958 and was supervised by MJ Sparnaay. He has produced results consistent with Casimir’s theories. The second experiment, by Steve K. Lamoreaux, was conducted in 1997. Instead of using two plates in the experiment, Lamoreaux paired a single plate with another plate that was part of a nearly precise sphere. This experiment also confirmed Casimir’s predictions. While negative energy states may not be observable, they have been demonstrated both in theory and by means of experiments.
