Stars Traveling Close To Light Speed Could Spread Life Through the Universe 184
KentuckyFC writes Stars in the Milky Way typically travel at a few hundred kilometers per second relative to their peers. But in recent years, astronomers have found a dozen or so "hypervelocity stars" traveling at up to 1000 kilometers per second, fast enough to escape our galaxy entirely. And they have observed stars orbiting the supermassive black hole at the center of the galaxy traveling at least an order of magnitude faster than this, albeit while gravitationally bound. Now a pair of astrophysicists have discovered a mechanism that would free these stars, sending them rocketing into intergalactic space at speeds in excess of 100,000 kilometers per second. That's more than a third of the speed of light. They calculate that there should be about 100,000 of these stars in every cubic gigaparsec of space and that the next generation of space telescopes will be sensitive to spot them. That's interesting because these stars will be cosmological messengers that can tell us about the conditions in other parts of the universe when they formed. And because these stars can travel across much of the observable universe throughout their lifetimes, they could also be responsible for spreading life throughout the cosmos.

I like this quote. "Some climate scientists, such as Professor Phil Jones, director of the Climatic Research Unit at the University of East Anglia, last week dismissed the significance of the plateau, saying that 15 or 16 years is too short a period from which to draw conclusions." It is only not long enough when the data doesn't support their agenda it seems.

Supermassive Black Holes Can Abort Star Formation 67
cremeglace writes "Astrophysicists have found that when a supermassive black hole quickly devours gas and dust, it can generate enough radiation to abort all the embryonic stars in the surrounding galaxy. It's not clear what this means for life's ability to take hold in such a bleak environment, but the research shows that the process might have determined the fates of many of the large galaxies in the universe."

He is not going for the guns yet. But wants to go after ammunition first. He supports the "INTER-AMERICAN CONVENTION AGAINST THE ILLICIT MANUFACTURING OF AND TRAFFICKING IN FIREARMS, AMMUNITION, EXPLOSIVES, AND OTHER RELATED MATERIALS". Basically, if this treaty is signed anyone who reloads ammunition and is not licensed by the government will be guilty of illicit manufacturing. You can have all the guns in the world, but with out ammunition they won't do you any good.

Here is a quick breakdown on AC power.
When dealing with AC power things aren't as simple as with DC power. You have to take into account the phase angle between the current and the voltage.
Power factor is equal to cosine of the phase angle between voltage and current.
There are three different measurements for AC power.
S = I x V (Apparent Power) = 127 x .3 = 38W in your case
P = I x V x PF (Real Power) = 127 x .3 x .7 = 26W in your case
To find Q (reactive power) you multiply current times voltage times the sine of the phase angle bewteen voltage and current.
So your kill a watt meter is giving you everything except reactive power.
