At Ten, Dark Energy "Most Profound Problem" in Physics

Since a long time ago, physicists thought that the law of gravity was making the universe expand to slow, "But ten years ago this month the Astronomical Journal accepted a paper for publication that revealed there is a dark side of the force. "
But a new study showed that instead of the universe expands slow, is going faster.
Scientists say that this is because of the dark energy, and this force repeals gravity. But this is not all, dark energy also is 74% of the universe... but maybe when more studies are done, the results can change: "This is game-changing science," Michael Turner, a cosmologist at the University of Chicago.
This is because they just stablished the phenomenon, but they still have to prove the cause.

What I think about this, is that is so cool that they found dark energy. I mean, it's not like is necessarly something bad, but in some movies and books they always talk about a dark side of things, and many times they don't think it is true, but things that are going on are coming closer to reality every time.
I also think that if this force is against the gravity law, then new things can be done, because if this is something that is stablished, then this discovery shows that not everything is as we think it can be and as we are used too, so it is really interesting to know about this, because it gets you to think about new ways of viewing things.

Death Toll May Climb in China Earthquake Aftermath

This article is about a city in China that had a huge earthquake and there were many deaths. The death toll has been estimated to become more than 50,000. The earthquake happened last Monday at 2:28 pm local time and measured 7.9 on the Richter scale. As many as 20,000 deaths have already occured and another 40,000 people are missing and probably are dead. The defence minister has ordered 101 helicopters to airlift people from devastated areas. Many schools, hospitals, roads have been hit hard. Aftershocks are devastating as well, in a high school, more than 1,000 students and teachers are dead or missing and in a middle school, 900 children are trapped because of a buiding collapse. This is the worst earthquake to hit China since 1976 when an earthquake measuring 7.5 at the epicenter, more than 240,000 people lost their lives.

This is devastating news and I am sure that if the Chinese government would allow outside help, people would be found more quickly and survivors would also get the help they need now instead of later.
