• Dark matter could be the result of fermions pushed into a warped fifth dimension.
• This theory builds on an idea first stated in 1999, but is unique in its findings.
• Dark matter makes up 75 percent of matter but has never been observed ... yet.
Scientists say they can explain dark matter by positing a particle that links to a fifth dimension.
While the “warped extra dimension” (WED) is a trademark of a popular physics model first introduced in 1999, this research, published in The European Physical Journal C, is the first to cohesively use the theory to explain the long-lasting dark matter problem within particle physics.
Our knowledge of the physical universe relies on the idea of dark matter, which takes up the vast majority of matter in the universe. Dark matter is a kind of pinch hitter that helps scientists explain how gravity works, because a lot of features would dissolve or fall apart without an “x factor” of dark matter. Even so, dark matter doesn’t disrupt the particles we do see and “feel,” meaning it must have other special properties as well.
