Neighboring Andromeda Galaxy to eat Milky Way in 5 billion years
Crawley, Australia (UPI) Sep 19, 2014
All galaxies grow by pulling in cosmic debris, gas and dust, and are rather efficient at converting it into new stars. But as galaxies age and grow more massive over time, their ability to create their own stars wanes, and they are forced to add on mass by swallowing up other smaller galaxies. A new study claims our own galaxy, the Milky Way, has already reached that tipping point - no longer able to produce our own fresh stars, we must resort cosmic cannibalism. It's a strategy that will even ... read more

What is life? It's a Tricky, Often Confusing Question What is life? This is a question that is often asked and typically confused. The confusion starts from the several uses of the word "life" in English. There are at least three usages as exemplified ... more		Monster galaxies gain weight by eating smaller neighbours Massive galaxies in the Universe have stopped making their own stars and are instead snacking on nearby galaxies, according to research by Australian scientists. Astronomers looked at more tha ... more		Reinterpreting dark matter Tom Broadhurst, an Ikerbasque researcher at the UPV/EHU's Department of Theoretical Physics, has participated alongside scientists of the National Taiwan University in a piece of research that explo ... more

The Swiss team of scientists aimed to transport the photon into a crystal without the two touching, and they did just that. The same team were able to accomplish this in 2003, but they were only able to teleport the light a little less than four miles. The reporting of the accomplishment can be found in the latest issue of Nature Photonics. ... more
