Corporate Taxes Are a Joke
Arguably, the U.S. now has a corporate tax code that’s the worst of all worlds. The official rate is higher than in most countries, so enormous time and effort are devoted to finding loopholes.
Economists have long pleaded for an overhaul of the corporate tax code, and both President Obama and Republicans now say they favor one, too. But it won’t be easy. Companies that use loopholes to avoid taxes don’t mind the current system, of course, and they have more than a few lobbyists at their disposal. Over the last five years, Boeing paid a total tax rate of just 4.5 percent, according to Capital IQ. Southwest Airlines paid 6.3 percent. And the list goes on: Yahoo paid 7 percent; Prudential Financial, 7.6 percent; General Electric, 14.3 percent.
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.
