In a new study, scientists say they can explain dark matter by positing a particle that links to a fifth dimension.
(Updated version of the previous article.)
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.
Although dark matter is a central part of the standard cosmological model, it’s not without its issues. There continue to be nagging mysteries about the stuff, not the least of which is the fact that scientists have found no direct particle evidence of it.
Despite numerous searches, we have yet to detect dark matter particles. So some astronomers favor an alternative, such as modified Newtonian dynamics (MoND) or modified gravity model. And a new study of galactic rotation seems to support them.
The idea of MoND was inspired by galactic rotation. Most of the visible matter in a galaxy is clustered in the middle, so you’d expect that stars closer to the center would have faster orbital speeds than stars farther away, similar to the planets of our solar system. What we observe is that stars in a galaxy all rotate at about the same speed. The rotation curve is essentially flat rather than dropping off. The dark matter solution is that galaxies are surrounded by a halo of invisible matter, but in 1983 Mordehai Milgrom argued that our gravitational model must be wrong.
Finding a material that could replace silicon is a critical task in nanoelectronics. For many years, graphene has appeared promising. However, its potential was compromised along the way because of destructive processing techniques and the absence of a new electronics paradigm to adopt it. The need for the next major nanoelectronics platform is greater than ever, as silicon is almost at its limit in supporting faster computation.
The strength of graphene, according to Walter de Heer, a professor at the Georgia Institute of Technology’s School of Physics, rests in its flat, two-dimensional structure, which is kept together by the strongest chemical bonds known.
