Is There a Resting Frame in Universe?

Physics is sometimes closer to philosophy when it comes to understanding the Universe. Dr. Donald Chang, a physicist at the Hong Kong University of Science and Technology, attempts to elucidate whether the Universe has a resting frame. An experiment proposed by Dr. Donald Chang aims at resolving divergence between special …

The only sample of metallic hydrogen on Earth has vanished

The physics world was abuzz with excitement (and skepticism) last month when scientists from Harvard University claimed they had created a stable sample of metallic hydrogen. Their initial testing and paper garnered a great deal of interest, as no one had thus far been able to prove the theoretical material …

Supersolid: Physicists Create New State of Matter

Two teams of physicists have independently created a mysterious new state of matter. The state is known as a supersolid and it combines the properties of both solid and superfluid states. Illustration of a supersolid state, in which the properties of a frictionless fluid and a crystalline state coincide. Image …

Oscillons, Gravitational Wave Factories in Very Early Universe

A team of theoretical physicists at the University of Basel, Switzerland, has found that in the very early Universe, so-called oscillons — strong localized fluctuations of the inflaton field — can act as ‘gravitational wave factories.’ According to Antusch et al, oscillons produced a characteristic peak in the otherwise broad …

Explosions used to make large quantities of graphene

Graphene was discovered in 2004, and right away its remarkable mechanical and electrical properties made it a hot topic of research. Graphene could be used for super-efficient batteries, solar panels, and much more. But after 13 years, we still don’t have any of that. The problem is that graphene is …
