The researchers based their model on a theory called <a href=\"http:\/\/en.wikipedia.org\/wiki\/Loop_quantum_cosmology\">the Loop Quantum Cosmology<\/a>, which was (originally) <a href=\"http:\/\/relativity.livingreviews.org\/Articles\/lrr-2005-11\/\">proposed<\/a> in 2003. At the end of the article, there&#8217;s a funny quote about how these physicist came up on LQC:\n<\/p>\n<p class=\"quote\">&#8220;From a physicist&#8217;s point of view, it is fully justified. Mathematicians perhaps would not be amused.&#8221;\n<\/p>\n<p>I hear that if you give mathematicians a couple of beers, you can convince them that the Earth is only 5,000 years old. I&#8217;m not joking: please try it on your local math teacher!\n<\/p>\n<p>This is important news: there&#8217;s finally <em>empirical<\/em> evidence that our galaxy, the proud Milky Way, <a href=\"http:\/\/news.bbc.co.uk\/2\/hi\/science\/nature\/7774287.stm\">has a white creamy coconut center<\/a> and a soft crunchy chocolate crust, that melts in the mouth, not in your hands. Or as astronomers would say, a black hole in its center. I may have mentioned this a couple of years ago, but this black hole story is actually <a href=\"http:\/\/www.google.ca\/search?hl=en&#038;q=a+black+hole+in+the+milky+way&#038;btnG=Google+Search&#038;meta=\">old news<\/a>, I mean astronomers were already convinced that our galaxy had a black hole in its center. Obviously, it took many years to collect the evidence for this. Additionally, witness the <a href=\"http:\/\/science.slashdot.org\/article.pl?sid=08\/12\/10\/1336228&#038;from=rss\">smartness of the Slashdot crowd<\/a>:\n<\/p>\n<p class=\"quote\">When i heard that there were black holes in other galaxies, i was fine with that, since they are so far away. But now i hear there is one in OUR galaxy? That&#8217;s kinda scary, since its so close to us!\n<\/p>\n<p>Oh: this Hubble telescope that they launched in the 80s, yes? It still seems to be hitting the news: this time, astronomers managed to <a href=\"http:\/\/dsc.discovery.com\/news\/2008\/12\/10\/carbon-dioxide-planet.html\">find CO2 in the atmosphere of a planet circling around a star<\/a>, what, 65 million light-years away.\n<\/p>\n<p>And hanging around the Discovery site: Did you know that 2008 will get <a href=\"http:\/\/dsc.discovery.com\/news\/2008\/12\/09\/time-second-change.html\">one extra second<\/a>? I remember this happened years ago too, which is exactly the reason why I tend to be at work 2 seconds later than normal.
