About us
Science Blog was started in August 2002. It lives, breathes and eats press releases from research organizations around the globe. Most of what you read here are press releases from the outfits named in the stories themselves. Got a news story you think belongs here?
Let's talk.
The other half of the equation is
blog posts from readers like you. So if you have an interest in science,

X-ray man:
There two kinds of people in the world. One kind do not understand GR and even basic physics. The other who have business with GR are corrupted like people in the times of Galileo!
In fact, Newtonian theory is only applicable to the system of one or two bodies. For the system of three or more bodies which have similar masses like stars, Newtonian theory and all other theories have no answer for their patterns! But people insist on the application of these theories to the description of galaxies as well as the whole universe, in exactly the same way that people believed the sun as well as the whole universe had revolved around the Earth. Of course, this endeavor is unsuccessful and people resort to the assumption that the vast majority of the universe is some magical yet never-observable dark matter, dark energy and so on.
"An important scientific innovation rarely makes its way by gradually winning over and converting its opponents: it rarely happens that Saul becomes Paul. What does happen is that its opponents gradually die out, and that the growing generation is familiarised with the ideas from the beginning.''
