Comment Re:Air Conditioners save lives (Score 2) 96

There is a strange movement in Europe against Air Conditioners.

Yes. But a large part of that is the difficulty in retrofitting it to their older buildings. In the USA, we have a large installed base of forced air heating. Which can be upgraded to a heat pump. Also, we (USA) have more stand alone single family dwellings. So remodeling or even piping in split systems is easier. And with a heat pump, you not only get more efficient heat, but A/C as well.

hate and refuse to promote air conditioners often use refrigerators and freezers in the same homes.

Completely different applications. Refrigerators/freezers are self contained and much smaller than an entire house. And they prevent food spoilage. A much more serious problem than hot weather.

But large black holes also have extreme gravity

But do they really? They have greater mass. But the Schwarzschild radius is (sort of) defined by that distance from an object's center where the escape velocity is equal to the speed of light. And that is what we think about when we say "gravity". So this value should be the same at the "surface" of every black hole.

If this is the case, then the effects occuring near this surface would be the same for all black holes, given an identical height above it. And given that, we would have trouble picking apart a redshift due to extreme distance (Hubble) from that caused by events close to that surface (gravitational red shift).

So if we can't really tell how far away it is, we can't reliably estimate its energy level.

Winner! This is about Chinese drone companies being forced to pay bribes to Trump to remove the tariffs, and if that fails then the fallback is that the tariff is enacted and acts as a national sales tax. Republicans have wanted a national sales tax for years because the lower and middle classes spend a larger percentage of their income on goods than rich people do. And for importers and retailers, tariffs are much worse than a sales tax: sales tax is only paid on items that were sold and the retailer has already collected the money that needs to be paid to the government while tariffs apply to all items imported, including items that may never be sold, and they need to be paid upfront which requires lots of extra liquidity.

That's true now but it's highly probable that China's economy will eventually outpace the U.S. to a point where they could tell us to piss off. Sure, it would hurt China's economy but it would hurt the U.S. a lot more. While that may seem unlikely today, it's something they may be willing to do if relations between the countries deteriorate significantly.

However, in the case of an emergency the executive can give itself more power. Emergencies like national security risks.

It's interesting that none of the Constitutional crises Trump has perpetrated have resulted in the use of emergency powers but any and all competition to his business interests seem to be rife with the use of emergency powers.

Paying a tariff on imported drones is a security measure in the same manner as charging an extra $45 for airline passengers who don't have a Real ID is a security measure. Evildoers don't have modest amounts of extra cash to throw at the U.S. government for the purpose of inflicting harm or death on proles, and if they do have that cash then they'd better be ready to pay for the privilege.
