In physics, a fifth force refers to a hypothetical fundamental interaction (also known as fundamental force) beyond the four known interactions in nature: gravitational, electromagnetic, strong nuclear, and weak nuclear forces. Some speculative theories have proposed a fifth force to explain various anomalous observations that do not fit ...
There are four known fundamental forces of nature—electromagnetism, the strong nuclear force, the weak nuclear force, and gravity. ... be the carrier of a fifth force,” particle physicist Jon ...
The strong interaction, or strong nuclear force, is the most complicated interaction, mainly because of the way it varies with distance. The nuclear force is powerfully attractive between nucleons at distances of about 1 femtometre (fm, or 10 −15 metres), but it rapidly decreases to insignificance at distances beyond about 2.5 fm. At ...
The X17 particle could be the force carrier for a postulated fifth force, possibly connected with dark matter, [4] and has been described as a protophobic (i.e., ignoring protons) [5] vector boson with a mass near 17 MeV/c 2.
The discovery could “completely change our understanding of the universe, with consequences for the unification of forces and dark matter.” Scientists believe they have discovered the fifth ...
Ephraim Fischbach (born 1942) is an American physicist and a professor at Purdue University.He is best known for his attempts to find a fifth force of nature [1] and his research relating to the detection of neutrinos. [2]
This boson would mediate a fifth fundamental force acting over a short range (12 fm) and perhaps explain the decay of these 8 Be excited states. [10] A 2018 rerun of this experiment found the same anomalous particle scattering and set a narrower mass range of the proposed fifth boson, 17.01 ± 0.16 MeV/c 2. [11]
Klein's Nature article [5] suggested that the fifth dimension is closed and periodic, and that the identification of electric charge with motion in the fifth dimension can be interpreted as standing waves of wavelength , much like the electrons around a nucleus in the Bohr model of the atom. The quantization of electric charge could then be ...
