POPSA Test of the Copernican Principle Disproving the Copernican Principle would amount to a a Copernican revolution on its own account :-) Also, certain aspects of general relativity would need a profound review. Fortunately it seems Copernicus was right after all. Or was he?

POPSWindow of Possibility TAKE YOURSELF OUT TO A FIELD some evening after everyone else is asleep. Listen to the migrant birds whisking past in the dark; listen to the creaking and settling of the world. Think about the teeming, microscopic worlds beneath your shoes—the continents of soil, the galaxies of bacteria. Then lift your face up. The night sky is the coolest Advent calendar imaginable: it is composed of an infinite number of doors. Open one and find ten thousand galaxies hiding behind it, streaming away at hundreds of miles per second. Open another, and another. You gaze up into history; you stare into the limits of your own understanding. The past flies toward you at the speed of light. Why are you here? Why are the stars there? Is it even remotely possible that our one, tiny, eggshell world is the only one encrusted with life?

POPSSpace Experts Call for ‘Fewer Astronauts, More Robots’ The suggestion sure makes a lot of economical sense. Resources should be focused to develop better technologies to carry load into orbit and beyond, because this is the real bottle neck of space exploration as of now. On the other hand, we cannot overlook the fact that sending men and women to space, ignites the imagination and inspires the coming generations. Space is the next frontier of adventure and mystery. The myth and the story are not less important than the economical aspect.

POPSCosmic crash unmasks dark matter It looks as if it is being seen through lots of little lenses. And each of these lenses represents a piece of dark matter. Astronomers used the Chandra X-ray telescope to map ordinary matter in the merging clusters, mostly in the form of hot gas, which glows brightly in X-rays. As the two clusters that formed MACSJ0025 merged at speeds of millions of kilometres per hour, hot gas in the two clusters collided and slowed down. However, the dark matter kept on going, passing right through the smash-up. The latest astronomical observations suggest that dark matter makes up some 23% of the Universe. Ordinary matter - such as the galaxies, gas, stars and planets - makes up just 4%. The remaining 73% is made up of another mysterious quantity; dark energy, which is responsible for speeding up the expansion of the cosmos.

POPSHubble Heritage Gallery of Images The more we see, the more we realize how much we were missing using ground based telescopes. Land telescopes were what we needed to check out the neighbor hood without blowing our minds. After the introduction now we need to look without water in our eyes. Hubble has done that, but we need to keep looking from the sky.We will see to the end of time, and find nothing. It will never contradict the existence of Now. We will be able to trace the path by which nothing became today
