Spacetime not so pixelated

Three photons from the same gamma ray burst, recorded in 2009 by the Fermi telescope and recently analyzed by Robert Nemiroff and colleagues, have demonstrated that spacetime is smooth below the Planck length.

Brian Dodson gives an explanation you can follow without a Physics PhD in Quantum spacetime more like foam rubber than beer foam.

According to the Michigan Tech group, spacetime is free of major irregularities on size scales below about 525 Planck lengths in size.

The Rednecks are coming, the Rednecks are coming

Actually, the rednecks are here and everywhere. Let me say, I'm not a big fan of these people. That's putting it mildly. Need I describe them? You know who I mean.This seems to be the time of year when they come out of the woodwork. Here in Indiana, as the weather gets nice, the motorcyclists are out in full force. I hate the noise cycles make. Then there's the Indianapolis 500 fans, the majority of which are rednecks. Interview them or a typical Pacer fan (big news as they face the Miami…See More
