In theoretical physics, negative mass is a hypothetical type of exotic matter whose mass is of opposite sign to the mass of normal matter, e.g. −1 kg....

its physical or chemical properties. Degenerate matter Exotic atoms Negative mass would possess some strange properties, such as accelerating in the direction...

particles with negative energies are consistent with Relativistic quantum theory, with some noting interrelationships with negative mass and/or time reversal...

Look up negative in Wiktionary, the free dictionary. Negative may refer to: Negative number Negative mass Negative energy Negative charge, one of the two...

effective mass in place of m. Plasma oscillations may give rise to the effect of the “negative mass”. The mechanical model giving rise to the negative effective...

calculations lead to an effective mass for the electrons that is typically negative at the top of a band. The negative mass is an unintuitive concept, and...

molecules in the gas phase to create analyte ions for analysis by mass spectrometry. Negative chemical ionization (NCI), charge-exchange chemical ionization...

The electron ( e− or β− ) is a subatomic particle with a negative one elementary electric charge. Electrons belong to the first generation of the lepton...

unstable with negative mass particles bursting into existence. The concept is hence tied to emerging theories of a continuously created negative mass dark fluid...

demonstrated that this negative component can never exceed the positive component of a system. A negative binding energy greater than the mass of the system itself...

fragmenting anionic species in mass spectrometry. It serves as a negative counter mode to electron capture dissociation. Negatively charged ions are activated...

"negative geometry", it is possible to do so by using "negative mass". The same equations do not, of themselves, rule out the existence of negative mass...

configurable energy-density field lower than that of vacuum (that is, negative mass) could be created. Proposed by theoretical physicist Miguel Alcubierre...

there may be many wormholes in the universe if cosmic strings with negative mass were generated in the early universe. Some physicists, such as Kip Thorne...

In 2018 astrophysicist Jamie Farnes proposed that a dark fluid with negative mass would have the properties required to explain both dark matter and dark...

tension and hence negative mass. The stability of such exotic matter strings is problematic; however, they suggested that if a negative mass string were to...

the effective mass can become negative, when the band curves downwards away from a maximum. As a result of the negative mass, the electrons respond to electric...

as "anti-mass" or negative mass, so far as is known, although scientists do discuss the concept. Antimatter has the same (i.e. positive) mass property...

generalization tensor–vector–scalar gravity (TeVeS), f(R) gravity, negative mass, dark fluid, and entropic gravity. Alternative theories abound. Primordial...

The term "negative binomial" is likely due to the fact that a certain binomial coefficient that appears in the formula for the probability mass function...

under the radical is negative. Because the total energy must be real, the numerator must also be imaginary: i.e. the rest mass m must be imaginary, as...

Massed negative practice is a proposed treatment for the tics of Tourette syndrome in which the individual with Tourette's "practices" tics continuously...

cumulative mass loss of glaciers reporting mass balance to the World Glacier Monitoring Service is −16 m. This includes 23 consecutive years of negative mass balances...

In microscopy, negative staining is an established method, often used in diagnostic microscopy, for contrasting a thin specimen with an optically opaque...

certain frequency bands, the effective mass density and bulk modulus may become negative. This results in a negative refractive index. Flat slab focusing...

reveals locations of positive mass "dark clusters", these researchers propose to locate "negative mass clumps" using negative weak lensing, i.e. where the...

sonic waves can exhibit negative refraction. Control of sound waves is mostly accomplished through the bulk modulus β, mass density ρ and chirality....

take in and release energy. Due to mass–energy equivalence, any object that has mass when stationary (called rest mass) also has an equivalent amount of...

propagation of any localized excitation (like a particle). Instead, the negative mass represents an instability to tachyon condensation, and all excitations...

simultaneously solved both the dark energy and dark matter problems, using a new negative mass dark fluid toy model that "brings balance to the universe". In 2019...
