Europe's Existential Crisis
Germany's controversial approach to fighting the euro crisis has split the European Union. The only thing agreed on is that the EU needs Germany as a motor if it is to survive.
Germany's controversial approach to fighting the euro crisis has split the European Union. Some countries are complaining about Berlin's rigid course, while others accuse Chancellor Merkel of betraying the European project. The only thing they can agree on is that the EU needs Germany as a motor if it is to survive. "The more the euro crisis expands into an existential crisis for the European Union, the more critical are other member states about Germany, the largest economy on the continent and the fourth largest worldwide." "This is all about Germany, and it's all about the end of the German appetite for writing checks to the periphery of Europe."
Here's the science of black holes, from supermassive monsters to ones the size of ping-pong balls.
- There's more than one way to make a black hole, says NASA's Michelle Thaller. They're not always formed from dead stars. For example, there are teeny tiny black holes all around us, the result of high-energy cosmic rays slamming into our atmosphere with enough force to cram matter together so densely that no light can escape.
- CERN is trying to create artificial black holes right now, but don't worry, it's not dangerous. Scientists there are attempting to smash two particles together with such intensity that it creates a black hole that would live for just a millionth of a second.
- Thaller uses a brilliant analogy involving a rubber sheet, a marble, and an elephant to explain why different black holes have varying densities. Watch and learn!
- Bonus fact: If the Earth became a black hole, it would be crushed to the size of a ping-pong ball.
Protected animals are feared to be headed for the black market.
In a breakthrough for nuclear fusion research, scientists at China's Experimental Advanced Superconducting Tokamak (EAST) reactor have produced temperatures necessary for nuclear fusion on Earth.
- The EAST reactor was able to heat hydrogen to temperatures exceeding 100 million degrees Celsius.
- Nuclear fusion could someday provide the planet with a virtually limitless supply of clean energy.
- Still, scientists have many other obstacles to pass before fusion technology becomes a viable energy source.
