Activists from the Violations Documentation Center (VDC) reported two separate attacks involving the use of chemical weapons in the Eastern Ghouta region. Independently, the Union of Medical Care and Relief Organizations also received reports of two separate incidents and we know from both the Syria Civil Defence and the Syrian American Medical Society that those hundreds exposed to the attack were brought to medical facilities where they showed symptoms consistent with exposure to a chemical agent.

Last year Scientific American published a controversial article titled "Pop goes the Universe", the three authors Anna Ljjas, Paul Steinhardt and Abraham Leob are skeptics of inflationary cosmology and they gave their reasons why. That was followed with a letter signed by 33 physicists who study cosmology, denouncing the article that had been published.

Originally I didn't even want to comment, the whole business of signing a letter denouncing the article instead of writing to the editor rubs me the wrong way. It reminds me when a hundred Nazi scientists were called on to denounce Einstein, if he were wrong you'd only have needed one. Science media should be an open space where people are allowed to hear about controversies in physics. Inflation is not a well established scientific theory like the Big Bang or evolution, and some very highly respected theoretical physicists are in real doubt.

Inflation probably is the correct theory, it's the best worked out mode…
