Physics constants not so constant. Unless you assume so...
Australian astronomers have combined all observations of supernovae ever made to determine that the strength of gravity has remained unchanged over the last nine billion years. (1) But is this really the case? How solid is such a conclusion? Digging a little deeper makes things more clear... The original paper can be found here. The…

Science without compass. A dangerous thing...
A defiant Yoweri Museveni has responded to U.S. President Barack Obama’s criticism of Uganda’s pending Anti-Homosexuality Bill by stating that he intends to sign it into law as soon as a scientific committee has completed its work. In a letter to Obama dated 18 February Museveni, Uganda’s president, defends the bill, which would introduce life…

Hawking, black holes and how everyone is right!
In 1974, Stephen Hawking found that matter and energy can escape a black hole through what is now known as Hawking radiation. However, he contended that the radiation would be so scrambled that scientists could never work backwards to understand what fell into the black hole in the first place. This violates a basic piece…

Physics constants, alpha, change...
One of physics’ most fundamental constants just got a little more... constant. Physicists have placed the strictest limit yet on how much the fine structure constant — which determines how strongly electrically charged objects interact — could change with the density of nearby matter. The fine structure constant, also known as alpha, has long been…

All of our life, a single measurement...
New research from the University of Adelaide shows that weight gain and increased head size in the first month of a baby's life is linked to a higher IQ at early school age. [1] Do you remember that funny Lucky Luke comic (Lucky Luke Collines Noirs) with some funny looking anthropologists who wanted to study…
