Everyone's a Critic, Literally
Today, online, everyone is a writer. Words have become a cheap bumper crop of little distinction. That’s a problem for the rarefied world of print and for artistic criticism.
Aside from unfamiliarity, there is resentment among the old print crew for new media. The very technologies that print writers must employ to keep themselves in the conversation are the same ones that seem to be putting them out of business. Once writers for high-flight glossy publications could expect a dollar or more a word. Perhaps we dreamed of filing remembrances of literary friends from a cozy cottage in Normandy. Today we are considered fortunate if we get to pull the oars at The Huffington Post for some stale breadcrumbs and the pleasure of the lash.
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.
