And that’s sending a shudder through the world of physics, making astronomers re-think some of its most basic concepts. |SOURCE| At issue is a number called the Hubble constant, a calculation for [...] Read more

New Material Becomes Invisible to Microwave Radiation with the Flip of a Switch

UMD physicists design self-cloaking material with potential applications in telecommunications and next-generation computing. |SOURCE| University of Maryland physicists have developed a new cloaking material that can become transparent to microwave radiation with the flip of a switch. Because many wireless communication devices rely on microwaves, [...] Read more

One of Stephen Hawking's Most Famous Theories About Black Holes Just Suffered a Huge Blow

One of Stephen Hawking's most famous theories about dark matter — that this mysterious and invisible substance is made up of primordial black holes — recently suffered a huge blow. That conclusion comes from a massive telescope that captured an image of an entire galaxy in one shot. |SOURCE| One of Stephen Hawking's most famous theories about dark [...] Read more
